If P(not yellow) = StartFraction 4 over 15 EndFraction, which best describes the probability of the complement of the event?
Answer:
The P(yellow) = 11/15
Step-by-step explanation:
Here, we have;
P(not yellow) = 4/15
Mathematically, the addition of the probability of an event and its complement adds up to be 1
The complement we have here is P(yellow)
Thus, mathematically we have;
P(not yellow) + P(yellow) = 1
P(yellow) = 1 - P(not yellow)
From the question P(not yellow) = 4/15
Plugging this value, we have;
P(yellow) = 1 - 4/15 = 11/15

A bus traveled on a level road for 3 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 3 hours. Find the average speed on the level triad if the entire trip was 252 miles
Answer:
65 mph on level road
Step-by-step explanation:
Set b as average speed on the level road and (b-20) = average speed on the winding road
Distance = speed * time
Level Road distance + winding road dististance = 285 miles
Substituting b and (b-20), we have,
3b + 2(b-20) = 285
3b + 2b - 40 = 285
5b = 285 + 40
5b = 325
b= 325/5
b = 65 mph on level road
Answer: 52 mph
Step-by-step explanation:
Assume the following :
a = average speed traveled on level road
(a - 20) = average speed traveled on winding road
Recall:
Distance = speed × time
Total distance traveled :
Level road distance + winding road distance = 252 miles
3a + 3(a - 20) = 252
3a + 3a - 60 = 252
6a = 252 + 60
6a = 312
a = 52 mph on a level triad

The coordinates A(0,0) B(0,4) and C(2,0)are graphed and connected together. What 3 dimensional shape will be created
A right triangle. The Origin connects 4 blocks up ON the y axis, then connects 2 on the x axis.
Solve the equation by completing the square. If necessary, round to the nearest hundredth. x2+10x=18
To solve the quadratic equation x² + 10x = 18 by completing the square, we rearrange the equation, complete the square, solve for x by taking the square root of both sides, and then isolate x. The two solutions are x = -5 + √43 and x = -5 - √43, which can be approximated if necessary.
To solve the equation x² + 10x = 18 by completing the square, we first need to move all terms to one side to get the equation in the form of ax² + bx + c = 0.
Subtracting 18 from both sides, we have x² + 10x - 18 = 0.
To complete the square, we take the coefficient of x, which is 10, divide it by 2 to get 5, and then square it to get 25. We add 25 to both sides of the equation and then subtract it right back to maintain the balance:
x² + 10x + 25 - 25 - 18 = 0
Now we group the perfect square trinomial and simplify:
(x + 5)² - 43 = 0
Next, we add 43 to both sides:
(x + 5)² = 43
Then we take the square root of both sides:
(x + 5) = √43
Subtract 5 from both sides to solve for x:
x = -5 ± √43
The solutions are x = -5 + √43 and x = -5 - √43.
If y - 12 = 23, what would you do to solve for x? *
option 1 - add the 12 to both sides
option 2 - subtract the 12 from both sides
option 3 - subtract 23
Answer:
Option 1 - add the 12 to both sides.
Step-by-step explanation:
If you meant solve for the variable, y, then you should:
Option 1 - add the 12 to both sides.
y - 12 = 23
Isolate the variable, y. Add 12 to both sides:
y - 12 (+12) = 23 (+12)
y = 23 + 12
Simplify:
y = 23 + 12
y = 35

Step-by-step explanation:
The alphabet game costs $.25 to play. Before the game, 26 slips of paper with a different letter of the alphabet on it are put into a bag. A player draws one slip from the bag. If the player draws a vowel (A, E, I, O, or U), he or she wins $1. If a player plays the alphabet game 2 times in a row, replacing the slip of paper after each turn, what is the probability that they win twice? Write as a fraction.
Answer: 25/676
Step-by-step explanation:
Number of possible outcomes = 26
In other to win, one must draw must be either (A, E, I, O or U)
Therefore required drws to win = 5
First draw:
P(win) = Total required outcome / Total possible outcome
P(win) = 5/26
Second draw:
P(win) = Total required outcome / Total possible outcome
P(win) = 5/26
Therefore,
P(winning twice) = (5/26) × (5/26) = 25/676
The probability of winning the alphabet game twice in a row is 25/676.
To calculate the probability of winning the alphabet game twice in a row, we need to consider the probability of drawing a vowel each time and then multiply these probabilities together since the events are independent.
First, we identify there are 5 vowels (A, E, I, O, U) in the alphabet, and there are 26 total letters. So the probability of drawing a vowel in one turn is 5/26.
To win twice in a row, you would need to draw a vowel during your first turn and then replace the slip and draw a vowel again on your second turn. Since the slip is replaced after each turn, the probability for each turn remains the same (5/26).
Therefore, the probability of winning twice is:
(5/26) * (5/26) = (25/676)
So, the probability of winning the alphabet game twice in a row is 25/676.
What is the equation of the line that passes through 1,2 and is parallel to the line whose equation is 2x + y - 1 = 0
Answer:

Answer:
43°.
Step-by-step explanation:
To find the measures of the other two angles, we will need to use various angle properties.
We can use the Supplementary Angles formula to find the adjacent angle to the angle that measures 123°.
180 - 123 = 57°. This is the measure of the first angle.
Now, to find the measure of the second angle, we know that these are vertical angles meaning they are congruent. Therefore, the measure of the angle is 80°.
To find 'x', we will simply need to subtract from 180:
180 - 80 - 57 = 43°.

Which answer explains why the sum of 12+12 is an even number
A.Any number plus 12 is even.
B.Both addends are equal.
C.Any number greater than 12 is even.
D.12+12 is equal to an odd number
Answer:
Even + Even = even
odd + odd = even
Odd + even = odd
even + odd = odd
Rule of thumb in addition.
Answer is B
Step-by-step explanation:
Final answer:
The sum of 12+12 is an even number because both addends are even numbers, and adding two even numbers always results in an even sum.
Explanation:
The question you're asking is about why the sum of 12+12 is an even number. To answer this, we need to understand a property of even numbers. An even number is any integer that can be divided by 2 without leaving a remainder. Adding two even numbers together will always result in another even number because the sum of two multiples of any number is a multiple of that number. Since 12 is an even number (it can be divided by 2 to get 6), adding it to itself (another even number) must result in an even sum.
It's not correct to say that any number plus 12 is even (Option A) because if you add 12 to an odd number, the result is odd. Option B is the closest to a correct explanation because both addends are equal and are even numbers. Saying any number greater than 12 is even (Option C) is incorrect because odd numbers also exist above 12. Finally, 12+12 is not equal to an odd number (Option D), so that choice is incorrect as well.

Dado el número N = 4752a, averigua qué valor ha de tomar "a" para que: a) N sea divisible por tres. b) N sea divisible por cinco. c) N sea divisible por 15. d) Cuando se divida N por 7 dé de resto 5.
Answer:
I will answer it in English:
a) We have te number N = 4752a
if we want to divide it by 3, then the addition of all the digits must be a multiple of 3.
Sum = 4 + 7 + 5 + 2 + a = 6 + 7 + 5 + a = 18 + a
and 18 is a multiple of 3, then we can have, a = 0, a = 3, a = 6, a= 9
b) A number is divisible by 5 if it ends on 5 or 0, so the possible values of a are 0 and 5.
c) we know that 15*3 = 45
then 15*3000= 45000
now we have:
4752a - 45000 = 252a
15*13 = 2520
then we have that a must be equal to zero, and:
15*(13 + 3000) = 47520
d) We want a number that when we divide it by 7, the surpass is 5.
a number is divisible by 7 if the difference between the number without the units and the double of the units is 0 or a multiple of 7.
in N = 4752x the unit is a, then we have:
D = 4752 - 2*x
now, let's choose a such we have a multiple of 7
we know that 5746 is a multiple of 7, so we can choose x= 3 and get:
D = 4752 - 2*3 = 5746
So the number N = 47523 is a multiple of 7, and when we divide it by 7 we will have a surpass of 0.
Then when we divide N + 5 by 7, we will have a surpass of 7.
This is: N + 5 = 47528
This means that the actual value of a that we need is 8.
