Answer:

25 feet

Step-by-step explanation:

The hypotenuse of the right triangle with legs 15 feet and 20 feet can be found using the Pythagorean theorem:

h^2 = 20^2 +15^2

h^2 = 400 +225 = 625

h = √625 = 25

The distance from the shadow tip to the flag pole tip is 25 feet.

Answer:

Step-by-step explanation:

Given that a nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks

90% confidence interval is

(317.2, 326.8)mg.

Using confidence intervals,we can check whether null hypothesis is true.

Here

$H_0: \bar x = 325\\H_a: \bar x$

(left tailed test at 10% significance level)

We check whether confidence interval 90% contains the mean value.

We find 325 belongs to the confidence interval

Hence H0 is true

The hot dogs do not satisfy.

Answer:

A, D

Step-by-step explanation:

When we multiply the fractions, we can get:

$\frac{1}{5^{4} }$

This is also equivalent to:

$5^{-4}$

When looking at the answer choices, the only ones that equal $5^{-4}$ are A and D because:

$(5^{-2})^{2} =5^{-4}$

$5^{2}*5^{-6} = 5^{-4}$
