Answer:

The answer is 56. Here's why:

Step-by-step explanation:

Pythagorean Therom works for any right triangle, and it states (a)²+(b)²=(c)². A and B are the height and base, and C is the hyptoanuse. We don't know the height, but we know the rest of the information:

(a)²+(33)²=(65)². This simplifies to (a)²+1089=4225. If we subtract 1089 from each side, we get (a)²=3136. The √3136 (Sqaure root of 3136) is 56.

Answer:

?=38

average rate of change =3 (on the way they partitioned the x's)

Step-by-step explanation:

This is a line because it has the same rise/run ( $\frac{y_2-y_1}{x_2-x_1}$ ) per pair of points.

That is, the following are equal:

$\frac{17-5}{2-(-2)}=\frac{26-17}{5-2}$

$\frac{12}{4}=\frac{9}{3}$

$3=3$

The slope (also called the rate of change) is 3.

This means the calculating of the last pair of points should have the same rise/run.

That is we should have:

$\frac{?-26}{9-5}=3$

$\frac{?-26}{4}=3$

Multiply both sides by 4:

$?-26=12$

Add 26 on both sides:

$?=12+26$

$?=38$

U 1995, 70% of all children in the U.S. were living with both parents. If 25 children were selected at random in the U.S., what

nikdorinn [45]

Answer:

The probability that at most 10 of them will be living with both of their parents is 0.0018

Solution:

Given, US 1995, 70% of all children in the U.S. were living with both parents. 25 children were selected at random in the U.S.,

We have to find what is the probability that at most 10 of them will be living with both of their parents?

Now, number of children picked (n) = 25.

Probability to be with parents = 70% = 0.7.

Our condition is 0 ≤ x ≤ 10.

Then, we have to calculate p(0 ≤ x ≤ 10).

We can calculate using binomial cumulative distribution frequency- binomial CDF

Now, p(0 ≤ x ≤ 10) = binomcdf(n, p, x) = binomcdf(25, 0.7, 10) = 0.00177840 ≈ 0.0018.

Hence, the probability is 0.0018
