Find the indicated probability. round to three decimal places. a test consists of 10

a. True

b. False questions. to pass the test a student must answer at least 6 questions correctly. if a student guesses on each question, what is the probability that the student will pass the test?

Answers

Answer 1

To answer this problem, we use the binomial distribution formula for probability:

P (x) = [n! / (n-x)! x!] p^x q^(n-x)

Where,

n = the total number of test questions = 10

x = the total number of test questions to pass =   >6

p = probability of success = 0.5

q = probability of failure = 0.5

Given the formula, let us calculate for the probabilities that the student will get at least 6 correct questions by guessing.

P (6) = [10! / (4)! 6!] (0.5)^6 0.5^(4) = 0.205078

P (7) = [10! / (3)! 7!] (0.5)^7 0.5^(3) = 0.117188

P (8) = [10! / (2)! 8!] (0.5)^8 0.5^(2) = 0.043945

P (9) = [10! / (1)! 9!] (0.5)^9 0.5^(1) = 0.009766

P (10) = [10! / (0)! 10!] (0.5)^10 0.5^(0) = 0.000977

Total Probability = 0.376953 = 0.38 = 38%

There is a 38% chance the student will pass.

Solve the problem by writing an inequality. A club decides to sell T-shirts for $12 as a fund-raiser. It costs $20 plus $8 per T-shirt to make the T-shirts. Write and solve an equation to find how many T-shirts the club needs to make and sell in order to profit at least $100. Show your work.

Answers

An algebraic equation containing an inequality may contain symbols such as <, >, ≤ and ≥. You should know the concept of profit first. Profit is the net income you acquired by getting the total revenue, and subtracting from it all the fixed and variable costs. So, in equation, that would be

Profit = Revenue - (Fixed Cost + Variable Cost)

You should note that the limit for profit is at least $100. So that means it can be more than $100 but can't be less than. Therefore, the symbol to be used is greater than or equal to, symbolized by ≥. Then the equation is

12x - (20 + 8x) ≥ 100, where x represents the minimum number of t-shirts to reach a profit of at least $100. Solving the equation,

12x - 20 - 8x ≥ 100
12x - 8x ≥ 100 + 20
4x ≥ 120
x ≥30

Therefore, the club needs to sell at least 30 shirts.

How can x2 = x2 + 2x + 9 be set up as a system of equations?

Answers

Final answer:

To set up x^2 = x^2 + 2x + 9 as a system of equations, we would have x^2 = x^2 + 2x + 9 and x = -4.5.

Explanation:

To set up x2 = x2 + 2x + 9 as a system of equations, we can separate it into two separate equations:

Equation 1: x2 = x2 + 2x + 9

Equation 2: 0 = 2x + 9

By rearranging Equation 2, we can rewrite it as:

x = -4.5

Therefore, the system of equations for x2 = x2 + 2x + 9 is: x2 = x2 + 2x + 9 and x = -4.5.

The standard form of the equation of a parabola is x=y^2+6y+1. What is the vertex form of the equation?
A. X=(y+3)^2-8
B. X=(y+3)^2-5
C. X=(y+6)^2-35

Answers

A. x = (y+3)^2-8 is the correct answer.
What you want to do is get the quadratic (y^2+6y+1) into it's root factor form, in other words, the quantity of (y+what) squared will equal y^2+6y+1. Well it's not a perfect square so we'll have to play around with it a little.
In the format ay^2 + by + c, completing the square first requires finding out what value would do that: c = (b/2)^2 = (6/2)^2 = 3^2 = 9
So we need y^2+6y+1 to have the last number (c) to equal 9 to have (y+b/2)^2, or (y+3)^2
How do we get 9 down to the 1 that we have for c?? 9-1=8, so just subtract 8.
That means that y^2+6y+1 is the same as (y^2+6y+9)-8, and y^2+6y+9 = (y+3)^2, so now we have: y^2+6y+1 = (y+3)^2-8, which is answer [A]

How much more is the rate of change of function 2 than the rate of change of function 1?

Answers

The graph is the horizontal line:

y=3  it has a slope of zero.

Function 2 is

y=3x+1, it is in slope-intercept form, y=mx+b where m is the slope and b is the y=intercept so in this case it has a slope of 3.

So the difference in slopes is 3-0=3
Final answer:

The rate of change of function 2 is 3 times greater than the rate of change of function 1.

Explanation:

The rate of change of a function measures how much the output of the function changes when the input changes by 1 unit. In function 1, since the graph is a straight line, the rate of change is constant. We can find the rate of change of function 1 by finding the slope of the line, which represents the rate of change. In function 2, the equation is y = 3x + 1, so the rate of change is 3. Therefore, the rate of change of function 2 is 3 times greater than the rate of change of function 1.

Suppose you toss a coin 100 times and get 76 heads and 24 tails. based on these​ results, what is the probability that the next flip results in a head​?

Answers

If it is a fair coin, the probability of the next flip resulting in "heads" is 50-50 or .5

 

The probability that the next flip results in a head​ is 50% or 0.5.

We have,

Total number of coins tossed = 100

Number of heads outcome = 76

Number of tails outcome = 24

Now,

The probability of getting heads in the tossing of coins 100 times.

= 76/100

= 0.76

= 76%

Now,

Generally for an unbiased coin.

The probability of getting a head in tossing a coin is 50%.

So,

Based on the results of the first 100 coin tosses, even if the probability of getting a head is 76% the probability that the next flip results in a head is still 50%.

Thus,

The probability that the next flip results in a head​ is 50% or 0.5.

The area of a certain rectangle is 288 yd2. the perimeter is 68 yd. what are the dimensions of the rectangle?

Answers

P = 2(L + W)
P = 68
68 = 2(L + W)
68/2 = L + W
34 = L + W
34 - L = W

A = L * W
A = 288
W = 34 - L

288 = L(34 - L)
288 = 34L - L^2
L^2 - 34L + 288 = 0
(L - 16)(L - 18)

L - 16 = 0
L = 16

L - 18 = 0
L = 18

not exactly sure which (length or width) , but one is 16 yds and one is 18 yds

The dimensions of the rectangle are a length of 16 yds and a width of 18 yds.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

Given that the perimeter is 68 yd

We know that the perimeter of a rectangle is:

P = 2(L + W)

∴ P = 68

68 = 2(L + W)

68/2 = L + W

34 = L + W

34 - L = W ....(i)

The area of a rectangle is:

A = L × W ....(ii)

∴ A = 288

Substitute the value W = 34 - L in equation (ii), and solve for L

288 = L(34 - L)

288 = 34L - L²

L² - 34L + 288 = 0

(L - 16)(L - 18)

L - 16 = 0 and L - 18 = 0

L = 16 and L = 18

Take L = 16 and substitute the value in the equation (i)

So, W = 34 - 16 = 18

Therefore, the rectangle's length is 16 yds and its width is 18 yds.

A survey asked 30 people what their favorite genre of television broadcasting was, and the results were tabulated above. Find the probability that a person chosen at random was female, given that they like comedy. Round the answer to the nearest hundredth.

Answers

The probability that a person chosen at random is female, given they like comedy, is approximately 0.53 or 53% .

First, let's find the total number of females who like comedy. In the Venn diagram, there are 8 females who like comedy. There are also 7 males who like comedy. So, there are 15 people who like comedy in total.

Next, we need to determine the total number of females. There are 16 females who like drama, and 4 females who like sports. Adding these together, we get 20 females in total.

Now, we can calculate the conditional probability that a female likes comedy given that she was chosen at random. The formula for conditional probability is P(A|B) = P(AnB) / P(B). In this case, event A is "being female" and event B is "liking comedy."

P(A|B) = (Number of females who like comedy) / (Total number of people who like comedy)

P(A|B) = 8 / 15

To express this as a percentage, multiply by 100:

P(A|B) * 100 ≈ 0.5333

Rounded to the nearest hundredth, the probability is 0.53 or 53%.

The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding 4 to the first equation of System A and the second equations are identical. They will have the same solution because they represent the same lines when plotted on the coordinate axes. They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A. Line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment AB. What is the length of AB? 1 unit 2 units 3 units 5 units For maslow, the most highly evolved motive is _______. self-actualization physiological need esteem intellectual need Which one of the following characteristics of a solid is of concern to geometry?
