Answer:

ST = 7.1 in

Step-by-step explanation:

we can use SOH-CAH-TOA because we've got a right triangle

side ST would be 'adjacent'

side TU would be the 'hypotenuse'

so we use Cosine because that's used when you're dealing with adjacent and hypotenuse:

cos 42° = ST/9.5

ST = cos 42° × 9.5

ST = 7.1

Hello!

The sum of all angle measures in a heptagon in 900°. We will subtract all of these angles from 900 to find our answer.

900-146-122-142-140-110-142=98

x=98°

I hope this helps!

19. A cross section of a water trough is in the shape of trapezoid with bases measuring 4 m and 12 m. what is the length of the

ludmilkaskok [199]

Given:

The bases of trapezoid measuring 4 m and 12 m.

To find:

The median of the trapezoid.

Solution:

The median of the trapezoid is the average of its bases.

$\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}$

The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:

$\text{Median}=\dfrac{4+12}{2}$

$\text{Median}=\dfrac{16}{2}$

$\text{Median}=8$

Therefore, the correct option is C.

Julli [10]

Answer:

The standard error of the mean is 0.0783.

Step-by-step explanation:

The Central Limit Theorem helps us find the standard error of the mean:

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 $\frac{\sigma}{\sqrt{n}}$ .
