Step-by-step explanation:

i took the test on khan academy :D

The probability of the number of times from the result that he got 11 or fewer free throws is; P(11 or fewer sucessess) = 0.2

We are told that he simulated 30 samples. From the dot plot, we can see how many times he got 10 free throws, 11 free throws, 12 free throws, 13 free throws, 14 free throws, 15 free throws.

Now, from the dot plot, the number of times that he had 11 or fewer free throw successes is 6 times.

Thus;

P(11 or fewer sucessess) = 6/30

P(11 or fewer sucessess) = 1/5

P(11 or fewer sucessess) = 0.2

Answer:

18 bulbs for $54

Step-by-step explanation:

if we get 6 bulbs for $18

we can keep going

12 bulbs for $36

18 bulbs for $54

or we can divide 54 by 18 and get 3

then we multiply 3 by 6 and get 18 bulbs :)

if im correct may i please get brainliest

Answer:

18 bulbs

Step-by-step explanation:

let x number of bulbs can be bought for $54.

[tex]\frac{6}{18} =\frac{x}{54} \\\frac{1}{3} =\frac{x}{54} \\\\3x = 54\\x =\frac{54}{3} \\x=18[/tex]

You will find the answer from my explanation.

Step-by-step explanation:

Let the cost of one small shirt be x

And that of a large shirt be y

From the expression above;

4x + 14y = 210; since the total cost of a small shirt by Wili is;

4 * x and the large shirts 14 * y

Similarly for Jordan we have:

12x + 11y = 110; since the total cost of a small shirt by Jordan is;

12 * x and the large shirts 11 * y

We now have two equations,

So you can solve both equations now using elimination method;

If you multiply all the variables of x and y in the first equation by 3 and then subtract the second equation from it, x would be eliminated remaining y;

Multiplying the first equation we have;

12x + 42y = 630

- 12x + 11y = 110

------------------------------

0. + 31y = 520

You can continue from there

Answer:

My opinion is that you can exist any many things as you navigate through life. This quote is very wrong because you can exist in doing things for other people and not just yourself! You can not be selfish your entire life! I think that you should be for other people! I think that doing stuff for yourself is okay to a certain extent!

Step-by-step explanation:

THIS IS SOOO WRONG( idk tho)

This quote is telling us that you can't exist unless you are doing something worth being remembered for. Through out our lives we all listen to what the world tells us, but not many of us actually do what we want to. We live our lives for someone else, but I plan to change that. Instead of letting the public decide how I should live my life I will live for me. I will work harder in school, become smarter than my parents and grow as a person. I want to be remembered for stepping out of my comfort zone and being different. This is the year that I exist, and show people that I exist for a purpose.

Answer:

  $119.58

Step-by-step explanation:

We expect Carol's annual tax bill to be the difference of her pay and exemption, multiplied by the tax rate:

  annual tax = ($45,000 -4,000) × 0.035 = $1,435

Then her monthly tax bill will be 1/12 of this:

  monthly state tax = $1435/12 = $119.58

Carol pays $119.58 in state taxes each month.

Answer:

-$25,000

Step-by-step explanation:

15% of $50,000 is $7,500 Therefore..

10 x $7,500 = $75,000 ( 10 being the amount of years and 7500 being the 15% )

$50,000 - $75,000 = -$25,000

Answer:

Carmen is $ 27, Henry is $ 80, and Goran is $ 20.

Step-by-step explanation:

be Carmen's money "c", Goran's "g" and Henry's "h"

Now, we organize the equations and we are left with:

c + g + h = 127

h = 4 * g

c = g + 7

replacing in the main one we have:

g + 7 + g + 4 * g = 127

6 * g = 127 - 7

g = 120/6

g = 20

now replacing:

h = 4 * 20 = 80

c = 20 + 7 = 27

therefore, Carmen is $ 27, Henry is $ 80, and Goran is $ 20.

Answer:

  B.  quadratic

Step-by-step explanation:

The equation y=x^2+7x-15 is a quadratic equation. It might be the result of a quadratic regression.

_____

The descriptors "linear," "quadratic," "exponential," and "power" describe the sort of equation that is used to try to match the data. Quadratic regression returns a quadratic equation.

Answer:

a) 0.426 = 42.6% probability that a customer waits less than a second for credit card approval.

b) 0.189 = 18.9% probability that a customer waits more than 3 seconds.

c) The minimum approval time for the slowest 5% of transactions is 5.39 seconds.

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The probability that x is lower or equal to a is given by:

[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]

Which has the following solution:

[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]

The probability of finding a value higher than x is:

[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]

An online retailer has determined that the average time for credit card transactions to be electronically approved is 1.8 seconds.

This means that [tex]m = 1.8, \mu = \frac{1}{1.8} = 0.5555[/tex]

(a) Use an exponential density function to find the probability that a customer waits less than a second for credit card approval.

This is [tex]P(X \leq 1)[/tex].

[tex]P(X \leq 1) = 1 - e^{-0.5555*1} = 0.426[/tex]

0.426 = 42.6% probability that a customer waits less than a second for credit card approval.

(b) Find the probability that a customer waits more than 3 seconds.

This is P(X > 3).

[tex]P(X > x) = 1 - P(X \leq 3) = 1 - (1 - e^{-0.5555*3}) = 0.189[/tex]

0.189 = 18.9% probability that a customer waits more than 3 seconds.

(c) What is the minimum approval time for the slowest 5% of transactions

This is x for which [tex]P(X \leq x) = 0.95[/tex]

So

[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]

[tex]0.95 = 1 - e^{-0.5555x}[/tex]

[tex]e^{-0.5555x} = 0.05[/tex]

[tex]\ln{e^{-0.5555x}} = \ln{0.05}[/tex]

[tex]-0.5555x = \ln{0.05}[/tex]

[tex]x = -\frac{\ln{0.05}}{0.5555}[/tex]

[tex]x = 5.39[/tex]

The minimum approval time for the slowest 5% of transactions is 5.39 seconds.

Answer:

E. We are 95% confident that 27.8% to 32.2% of all Chinese adults smoke.

Step-by-step explanation:

x% confidence interval between a and b.

Interpretation: We are x% sure that the true value is between a and b.

In this question:

95% confidence level

30% with a margin of error of 2.2%.

So

30 - 2.2 = 27.8%

30 + 2.2 = 32.2%

So the correct answer is:

E. We are 95% confident that 27.8% to 32.2% of all Chinese adults smoke.

  y = -3/4x -15/4

Step-by-step explanation:

We assume you mean the given line to be ...

  y = -3/4x -21/4

The slope of this line is -3/4. The parallel line will have the same slope.

__

In point-slope form the equation of the line you seek is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

  y = -3/4(x -(-5)) . . . . .substitute m=-3/4 and (h, k) = (-5, 0)

  y = -3/4x -15/4

Answer:

PSP maybe?

Step-by-step explanation:

Answer:

The answer is 886.

You need to find the area of each specific shape and then add them together.

19 * 11 = 209, which is the area of the rectangle in the middle.

34 * 16 = 544, which is the area of the rectangle on the bottom of all the other shapes.

Now the triangle is a little more complicated. It only gives you the length of both the triangle and the rectangle combined, so first you need to subtract the length of the rectangle.

25 - 11 = 14, which is the length of the triangle.

Next, to find the area of a triangle, you need to multiple the length times the height and then divide it by two. 14 * 19 = 266. Divide 266 by 2 and you get 133.

Now, like I said earlier, add all of these together.

544 + 209 + 133 = 886.

Answer:

9 and 11

Step-by-step explanation:

The squareroot of 202 is 14... so the numbers are both less than 14.

9*9= 81

11*11= 121

121+81= 202

Answer:

Step-by-step explanation:

(9^2) + (11^2) Simplify the exponents

81 + 121 = 202

You would write AB with a horizontal line segment over the letters A and B

So you would write this [tex]\overline{AB}[/tex]

If you cannot draw that on your computer, then I would stick to saying "segment AB".

line segment is used to name a segment that has an endpoint at point A and another endpoint at point B

A line segment is a part of line that is bounded by two distinct end points , and contains every point on the line that is in between its endpoint  .

since , in question it is given that their are two end points A and B then, it will form a line segment named AB

the answer is line segment
