Answer:

x=20

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

21 ^2 + x^2 = 29^2

441+x^2 =841

Subtract 441 from each side

x^2 = 841-441

x^2 = 400

Take the square root of each side

sqrt(x^2) = sqrt(400)

x = 20

Answer:

$\boxed{x = 20}$

Step-by-step explanation:

Hey there!

Well to find x we need to use the Pythagorean Theorem, which is.

$a^2 + b^2 = c^2$

We have a which is 21 and 29 which is c.

$(21)^2 + x^2 = (29)^2$

$441 + x^2 = 841$

$-441$

$x^2 = 400$

$x = 20$

So the missing side "x" is 20.

Hope this helps :)

The distribution of the number of siblings for students at a large high school is skewed to the right with mean 1.8 siblings and

morpeh [17]

Answer:

E. Approximately normal with standard deviation less than 0.7 sibling

Step-by-step explanation:

To solve this question, we use the Central Limit theorem.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

Skewed right distribution, with $\mu = 1.8, \sigma = 0.7$

Sampling distribution of the sample mean for samples of size 100

By the Central Limit Theorem, they will be approximately normal, with mean $\mu = 1.8$ , and standard deviation $s = \frac{0.7}{\sqrt{100}} = 0.07$

So the correct answer is:

E. Approximately normal with standard deviation less than 0.7 sibling

Find the derivative of ((t^4-6)^3)*((t^3+6)^4)

rjkz [21]

=d/dx((t^4-6)^3) * (t^3+6)^4 + d/dx((t^3+6)^4) * (t^4-6)^3
=3*(t^4-6)^2 * (t^3+6)^4 * d/dx(t^4-6) + 4*(t^3+6)^3 * (t^4-6)^3 * d/dx(t^3+6)
=3*(t^4-6)^2 * (t^3+6)^4 * 4t^3 + 4*(t^3+6)^3 * (t^4-6)^3 * 3t^2
Simplify that if youd like
