Lets say that the vertical line in Y and Horizontal line in X
Take any point from either the number 8 diagonal or number 17 diagonal and see the value it has on both X and Y line and sum them , u will find the sum is always the same , this is because all the squares made by closest numbers r the same as any of the squares in this , think this as a graph paper that makes more sense if u r trying to understand ....

2х + Зу = 24<br> What is the x and y intercept

DochEvi [55]

Answer:

rearrange into y=mx+c

so it becomes

3y= -2x+24

y= (-2/3)x+24

substitute values for x

when x is 0

y is (-2/3)*0=0 +24 =24

<h2>y=24</h2>

for x intercept

0=(-2/3)*x+24

0-24=-2/3*x

-24/(-2/3)=x

<h2>x= -36</h2>

Fifty people were surveyed about their favorite flavor of frozen yogurt. The results of the survey are displayed in the circle g

Ksju [112]

The answer is 2. This is because 2 = 4% of 50.

You can think of it like this:

4 is 4% of 100.

50 is half of 100.

Therefore, 4% of 50 is HALF of 4% of 100.

4 divided by 2 = 2

Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five event

enot [183]

Answer:

$P(x < 3) = 25\%$

$E(x) = 3$

Step-by-step explanation:

The given parameters can be represented as:

$\begin{array}{ccccccc}x & {5} & {4} & {3} & {2} & {1}& {0} & P(x) & {25\%} & {30\%} & {20\%} & {15\%} & {5\%} & {5\%} \ \end{array}$

Solving (a): P(x < 3)

This is calculated as:

$P(x < 3) = P(x = 0) + P(x = 1) + P(x =2)$ ----- i.e. all probabilities less than 3

So, we have:

$P(x < 3) = 5\% + 5\% + 15\%$

$P(x < 3) = 25\%$

Solving (b): Expected number of events

This is calculated as:

$E(x) = \sum x * P(x)$

So, we have:

$E(x) = 5 * 25\% + 4 * 30\% + 3 * 20\% + 2 * 15\% + 1 * 5\% + 0 * 5\%$

$E(x) = 125\% + 120\% + 60\% + 30\% + 5\% + 0\%$

$E(x) = 340\%$

Express as decimal

$E(x) = 3.40$

Approximate to the nearest integer

$E(x) = 3$
