Answer:

Y intercept is 0, slope is 15

Step-by-step explanation:

Hi! This is 2023elliottsg I just now found your question, the y intercept is 0 because the line meets the y axis at (0,0)

the slope is 30/2 which simplifies to 15 because from point (4,60) it rises 30 and runs 2 over to point (6,90)

Answer:

See below

Step-by-step explanation:

Hello! I see your teacher is a Harry Potter fan. Anyways,

1) The y-intercept is when you plug x as 0 or it's when the line crosses the y axis. The easiest way to find the y-intercept is to look at the graph and see where the graph starts off from the y axis.

We can see that the line starts off from (0,0) so the y-intercept is (0,0).

In this case, the y-intercept represents the initial income when you haven't start working yet.

2) The formula for slope is y2-y1/x2-x1. We can find any two points on the line to do this equation. Lets take (0,0) and (2,30).

Let's now plug in the y, 30 - 0

And then the x, 2 - 0

Together they are 30 - 0/ 2 - 0

Or 30/2 = 15.

The slope is 15

In this case, the slope represents the amount of income earned per hour/every hour.

A rectangular box is 32 cm wide and 36 cm high. If the surface area of the box is 4344 square​ centimeters, find the length of t
AnnZ [28]

To find the surface area, multiply length x width x height.

let "length" = l

l x 32 x 36 = 4344

Simplify

l x (32 x 36) = 4344

l x 1152 = 4344

Isolate the length. Divide 1152 from both sides

(l x 1152)/1152 = (4344)/1152

l = 4344/1152

l = 3.77 (rounded)

3.77 cm is your length.

hope this helps

Suppose a basketball player has made 231 out of 361 free throws. If the player makes the next 2 free throws, I will pay you $31.
statuscvo [17]

Answer:

The expected value of the proposition is of -0.29.

Step-by-step explanation:

For each free throw, there are only two possible outcomes. Either the player will make it, or he will miss it. The probability of a player making a free throw is independent of any other free throw, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Suppose a basketball player has made 231 out of 361 free throws.

This means that p = \frac{231}{361} = 0.6399

Probability of the player making the next 2 free throws:

This is P(X = 2) when n = 2. So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{2,2}.(0.6399)^{2}.(0.3601)^{0} = 0.4095

Find the expected value of the proposition:

0.4095 probability of you paying $31(losing $31), which is when the player makes the next 2 free throws.

1 - 0.4059 = 0.5905 probability of you being paid $21(earning $21), which is when the player does not make the next 2 free throws. So

E = -31*0.4095 + 21*0.5905 = -0.29

The expected value of the proposition is of -0.29.
