In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549
The probability of picking a black card and then a red card from a standard deck without replacement is 13/51.
To calculate the probability of selecting a black card and then a red card from a standard deck without replacement, we need to consider the sequence of the two events. Initially, the deck contains 26 black cards (spades and clubs) and 26 red cards (diamonds and hearts). The probability P(A) of picking a black card first is 26/52 or 1/2.
After one black card has been removed, there are now 51 cards left in the deck with 26 red cards remaining. The probability P(B) of then picking a red card is 26/51. To find the overall probability of both events happening in sequence, we multiply the probabilities:
[tex]P(A and B) = P(A) \times P(B) = (\frac{1}{2}) \times (\frac{26}{51})[/tex]
This simplifies to P(A and B) = [tex](\frac{26}{102})[/tex] which can be further simplified to [tex](\frac{13}{51}).[/tex]
Identify, graph, and state the symmetries for the polar equation r=2+2sintheta.
Which are the critical points in the graph? please help
Answer:
Graph = Cardioid
Axis of symmetry = y-axis
Critical points= [tex]\frac{\pi}{2} , \frac{3\pi }{2}[/tex]
Step-by-step explanation:
General equation for this type of cardioid is:
a ± b sinθ
Condition for a cardioid = [tex]\frac{a}{b} = 1[/tex]
Axis of symmerty according to the graph of 2 + 2 sinθ is along y-axis.
Critical points:
r = 2 + 2 sinθ ⇒ r = 2(1 + sinθ) ⇒ r' = 2 cosθ
∵derivative of 1 + sinθ = cosθ
For finding critical point the derivative is equal to zero,
2 cosθ = 0 ⇒ cosθ = 0
the value of cosθ is equal to zero at intervals: [tex]\frac{\pi}{2} , \frac{3\pi }{2}[/tex]
So, critical points = [tex]\frac{\pi}{2} , \frac{3\pi }{2}[/tex]

help quick. One car traveled 220 miles and drove 10 mph hour slower than a second car which drove 260 miles. If the cars were traveling for the same time, how fast was the first car traveling?
65 mph
75 mph
55 mph
85 mph
Answer:
55mph
Step-by-step explanation:
car A distance, d1= 220
car b distance, d2= 260
speed of car A, s1= speed of car B- 10
let speed of car B be s2
s1= s2-10
speed = distance/time
time= distance/speed
As time of car A= time of car B
distance of Car A/speed of Car A=distance of Car B/speed of Car B
220/s2-10= 260/s2
s2=(s2-10)260/220
s2=65
s1= s2- 10
= 65-10
=55
hence speed of first car is 55mph !
Answer: 55 mph

You are in charge of buying the chips and soda for
a party. You must spend $52. The chips cost $5
per bag and the soda costs $3 for a gallon bottle.
You want to buy 14 items. How many
bottles of soda should you buy?
Show work
Answer:
9 bottles of soda can be bought.
Step-by-step explanation:
Let chips represented by x
and soda represented by y
then
x + y = 14 eq(1)
and
5x + 3y = 52 eq(2)
Solving the equations simultaneously we can find the value of x and y
Multiplying eq(1) with 5 and subtracting from eq(2)
5x + 3y = 52
5x + 5y = 70
- - -
___________
-2y = -18
y = -18/-2
y = 9
Putting value of y in eq(1)
x + y =14
x + 9 = 14
x = 14 - 9
x = 5
As y represents the soda, so 9 bottles of soda can be bought.
if y=-3x, find x's and y's value in 4x-2y=-20
Answer:
x=-2
Step-by-step explanation:
Answer:
x = - 2
y = 7
Step-by-step explanation:
4x - 2y = - 20
Now substitute - 3x for y.
4x - 2(-3x) = -20 combine the xs in the brackets
4x + 6x = - 20 Make the addition
10x = - 20 Divide by 10
x = - 20/10 Do the division
x = - 2
===============
3x - 2y = - 20 Put - 2 in for x
3(-2) - 2y = - 20 remove the brackets
- 6 - 2y = - 20 Add 6 to both sides
-2y = - 20 + 6 Combine
-2y = - 14 Divide by - 2
y = - 14/-2
y = 7

Final answer:
The question appears to involve solving a quadratic equation using the quadratic formula, but there seems to be a typo in the provided figures. Nevertheless, the solution process entails substituting the given values into the quadratic formula and solving for x, which may result in two possible solutions depending on the discriminant.
Explanation:
The question involves solving a quadratic equation of the form ax² + bx + c = 0 using the quadratic formula, which is x = (-b ± √(b² - 4ac)) / (2a). Based on the provided values of a, b, and c, we would substitute these into the quadratic formula to find the solutions to the equation. It seems there may be a typo in the original question, as the given values do not match any standard form of a quadratic equation nor the matrix form of a linear system. However, I will provide a general step-by-step solution for the quadratic equation based on the format provided in the reference information.
First, calculate the discriminant using the formula √(b² - 4ac). Then, use the values of a, b, and c to evaluate the positive and negative solutions of x using the quadratic formula. For example, if a = 1, b = 0.0211, and c = -0.0211, the solutions would be found as follows:
-0.0211 ± √(0.0211)² - 4(1)(–0.0211)
2(1)
It is important to note that this structure is indicative of the process and the actual computations will differ with the correct values provided for a, b, and c.

Answer:
The answer is 6 schools.
In a box and whisker plot, every piece of whisker or box represents 25% of the whole number of schools.
The schools participated 1 year or less are represented by the left part of the whisker. Which stands for 25%.
BOOM
Step-by-step explanation:
On analyzing the boxplot, we find that 6 schools have participated for 1 year or less.
What is a boxplot?A boxplot is a standardized way of displaying the distribution of data based on a five number summary (minimum, first quartile (Q1), median, third quartile (Q3), and maximum).
The box extends from 1 to 6 on the number line. This implies first quartile (Q1) = 1 and third quartile (Q3) = 6.
There is a vertical line at 3.5, median = 3.5.
The whiskers end at 0 and 8, i.e., minimum = 0 and maximum = 8.
Since, Q1 = 1, this implies 25% of the schools participated for 1 year or less.
(First quartile (Q1) is the value under which 25% of data points are found when they are arranged in increasing order.)
Number of schools that have participated for 1 year or less = 25% of 24 = [tex]\frac{25}{100} * 24 = 6[/tex]

rolling a 5= 11/100
getting tails=71/29
i’m pretty sure you times the fractions together to get an overall probability
The probability of rolling a 5 on number cube and tail on coin is:
[tex]P(A\bigcap B)=\dfrac{781}{10000}[/tex]
or
[tex]P(A\bigcap B)=0.0781[/tex]
Step-by-step explanation:Let A denote the event of rolling a 5 on the number cube.
and B denote the event of coin landing on tails.
Let P denote the probability of an event.
Also, event A is independent of event B.
( Since, both the events are not affected by happening of each other )
We are asked to find the probability: P(A∩B)
We know that:

3.3 m2
7.1 m2
17.9 m2
18.8 m2
Answer:
The area of the deck that surrounds the hot tub is 17.9 m².
Step-by-step explanation:
Base of deck = 5 m
Height of deck = 5 m
Area of deck = base*height

can you find x for the following equation?
7x+12=3(5x-12)
7x + 12 = 3(5x - 12)
Step 1: Distribute the 3 to the numbers in the parentheses (5x and -12)
7x + 12 = (3 × 5x) + (3 × (-12))
7x + 12 = 15x + (-36)
Step 2: Combine like terms
x's go with x's (7x and 15x)
Subtract 7x to both sides
(7x - 7x) + 12 = (15x - 7x) + (-36)
(0) + 12 = 8x - 36
12 = 8x - 36
Normal numbers go with normal numbers
Add 36 to both sides
12 + 36 = 8x + (-36 + 36)
48 = 8x
Step 3: Isolate x by dividing 8 to both sides
48/8 = 8x/8
6 = x
Hope this helped!
Answer:
x = 6
Step-by-step explanation:
Eliminate parentheses using the distributive property.
7x +12 = 15x -36
You have x-terms and constants on both sides of the equal sign. One way to approach this is to find the x-term with the least coefficient (it is 7x) and subtract everything on that side of the equation.
(7x +12) -(7x +12) = (15x -36) -(7x +12)
Simplify, also known as "collect terms."
0 = 8x -48
Now, divide by the coefficient of x: 8.
0 = x -6
Add the opposite of the constant: 6.
6 = x
__
Alternate solution
By looking for the x-term with the smallest coefficient, we get a positive result when we subtract that term. If we were to subtract 15x from both sides of the equation, it would be ...
-8x +12 = -36 . . . . . . . with a negative x-coefficient
You can still work the problem this way, but it can introduce errors if you're not careful with signs. To finish this, we would subtract 12 to get the x-term by itself:
-8x = -48
Then we would divide by the x-coefficient, -8.
x = -48/-8 = 6 . . . . . same solution; same number of steps
_____
Whenever you add, subtract, multiply, divide, you do the same thing to both sides of the equation.

Ava and Kelly ran a road race, starting from the same place at the same time. Ava ran at an average speed of 6 miles per hour. Kelly ran at an average speed of 8 miles per hour. When will Ava and Kelly be 3/4 mile apart?
To find out when Ava and Kelly will be 3/4 mile apart, we can set up a distance equation based on their average speeds. The time it takes for Ava and Kelly to be 3/4 mile apart is 22.5 minutes.
Explanation:To find out when Ava and Kelly will be 3/4 mile apart, we can set up a distance equation based on their average speeds.
Let's assume that the time it takes for Ava and Kelly to be 3/4 mile apart is t. Ava's distance can be represented by the equation 6t, while Kelly's distance would be 8t. We can set up the equation:
6t - 8t = 3/4
Simplifying, we have -2t = 3/4. To solve for t, we can multiply both sides of the equation by -1/2 to eliminate the negative sign:
t = (3/4) * (-1/2) = -3/8
Since time cannot be negative, we can conclude that Ava and Kelly will be 3/4 mile apart after 3/8 of an hour or 22.5 minutes.

Step-by-step explanation:
To find out when Ava and Kelly will be 3/4 miles apart, we can set up an equation.
[tex]d = 8t-6t=2t[/tex]
t is the time in hours and d is the distance between the two girls in miles. Kelly runs at 8 miles/hour (represented by 8t) and Ava runs at 6 miles/hour (represented by 6t), and the distance between them can be calculated by subtracting Ava's distance from Kelly's distance.
To find out when they will be 3/4 miles apart, set d to 3/4 and solve for t.
[tex]\frac{3}{4} =2t\\\frac{3}{8}=t[/tex]
So, they will 3/4 miles apart after 3/8 hours.

identify the type of sampling (simple random sample, cluster, stratified, convenience, systematic
The scenarios provided represent different types of sampling methods, such as stratified, cluster, simple random, and systematic, based on how the samples are selected from the population.
Explanation:The type of sampling can be determined based on how the samples are chosen from the population. Here, we discuss different sampling methods using the provided scenarios.
Stratified sampling is used when the soccer coach selects players from different age groups to form a team. Each age group is a stratum.Cluster sampling takes place when a pollster interviews all human resource personnel in a few high tech companies. Each company is a cluster.When a high school educational researcher interviews an equal number of female and male teachers, this is an example of stratified sampling as well.The high school principal who polls an equal number of students from each grade level utilizes stratified sampling.A sample of high school students chosen by first organizing by class and then selecting an equal number from each also exemplifies stratified sampling.If a completely random method is used to select students giving each one the same chance of being chosen, this represents simple random sampling.When selecting a sample proportionate to class standings in a college, and drawing from each class based on their representation in the total population, stratified sampling is again used.Using a random number generator to select every 50th student from an alphabetical list represents systematic sampling.The sum of a and b is equal to 24.

The function c(f) = 5/9 (f-32) allows you to convert degrees to Fahrenheit to degrees Celsius. Find the inverse of the function so that you can convert degrees Celsius back to degrees Fahrenheit
For this case we have the following function:
[tex]c (f) = \frac {5} {9} (f-32)[/tex]
We must find the inverse function. For this we follow the steps below:
Replace c (f) with y:
[tex]y = \frac {5} {9} (f-32)[/tex]
We exchange variables:
[tex]\frac {5} {9} (y-32) = f[/tex]f = \frac {5} {9} (y-32)
We solve for "y":
[tex]\frac {5} {9} (y-32) = f[/tex]
We multiply by[tex]\frac {9} {5}[/tex]on both sides of the equation:
[tex]y-32 = \frac {9} {5} f[/tex]
We add 32 to both sides of the equation:
[tex]y = \frac {9} {5} f + 32[/tex]
We change y by[tex]c^{ -1} (f):[/tex]
[tex]c^{-1} (f) = \frac {9} {5} f + 32[/tex]
Answer:
[tex]c^{-1} (f) = \frac {9} {5} f + 32[/tex]
Answer:
[tex]f(c)=\frac{9}{5}c+32[/tex]
Step-by-step explanation:
Given function that is used to convert degrees to Fahrenheit to degrees Celsius,
[tex]c(f)=\frac{5}{9}(f-32)[/tex]
Let y represents the output value of the function and x represents the input value,
[tex]y=\frac{5}{9}(x-32)[/tex]
Switch x and y,
[tex]x=\frac{5}{9}(y-32)[/tex]
Isolate y,
[tex]9x=5(y-32)[/tex]
[tex]\frac{9}{5}x=y-32[/tex]
[tex]\implies y = \frac{9}{5}x+32[/tex]
[tex]\implies f(c)=\frac{9}{5}c+32[/tex]
Which is the required function.

Your friend George is 6 feet tall and his shadow is 10 feet long. At the same time, the shadow of the flagpole was 85 feet long. What is the height of a flagpole?
A. 141.6 feet.
B. 51 feet.
C. 1.4 feet.
D. 60 feet.
Answer: 51 feet
Since we know George's height, the length of George's shadow, and the length of the flagpole's shadow we have all the information we need
Now we can set up a relationship between George and the flagpole:
[tex] \frac{6}{10} = \frac{x}{85} [/tex]
6 represents George's height
10 represents the length of George's shadow
x is the unknown height of the flagpole
85 is the length of the flagpole's shadow
Now you solve for x:
[tex]x = \frac{85 \times 6}{10} \\ x = \frac{510}{10} \\ x = 51[/tex]
So, the height of the flagpole is 51 feet
