Answer:

Step-by-step explanation:

${ {a}^{b} }^{c} = {a}^{bc } \\ in \: this \: case \\ { ({8}^{n}) }^{3} = {8}^{3n} \\ \\ {8}^{3n} = {8}^{6 } \\ 3n = 6 \\ n = \frac{6}{3} = 2$

Use the Pythagorean theorem to find the length of the leg in the triangle below. side a is 35 , and side c is 21. What is B?

garri49 [273]

Answer:

b=-784!

Step-by-step explanation:

If pythagorean theorem is the following (see below), then we can work backwards in order to solve for b!

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

$35^2 +b=21^2\\1225+b=441$

Now all that's left is to subtract 1225 and we should have our answer!

$b=-784!$

An analysis of the grades on the first test in History 101 revealed that they approximate a normal curve with a mean of 75 and a

QveST [7]

Answer:

b. 85

Step-by-step explanation:

Average grade (μ) = 75

Standard deviation (σ) = 8

Assuming a normal distribution, the z-score corresponding to the upper 10% of the test grades is z = 1.28.

The minimum grade 'X' within the top 10% is given by:

$z=\frac{X-\mu}{\sigma}\\1.28=\frac{X-75}{8}\\X=85.24$

Rounding to the nearest percent, the dividing point between an A and a B grade is 85.

A woman is 5 1⁄7 inches taller than her daughter. The woman is 66 1⁄7 inches tall. How tall is her daughter?

rodikova [14]

Her daughter's length would be 61 inches because 66 1/7 - 5 1/7 = 61 in.
