pentagon [3]

Answer:

1331π cm³

Explanation:

$\sf V_{cylinder} = \pi (radius)^2 (height)$

Here given:

radius: 11 cm
height: 11 cm

Hence find volume:

$\sf \rightarrow\pi (11)^2 (11)$

$\sf \rightarrow 121\pi ( (11)$

$\sf \rightarrow 1331\pi \quad \approx \:\:\ 4181.46 \ cm^3$

The perimeter of the scalene triangle is 54.6 cm.

olchik [2.2K]

Answer:

b = 45.9 - c

Step-by-step explanation:

A scalene triangle has non of its sides equal.

Perimeter = 54.6

side a = 8.7 cm

side b = unknown

side c = unknown

Perimeter of a shape is sum of all its sides.

Perimeter = a + b + c

54.6 = 8.7 + b + c

Making b the subject

b = 54.6 - 8.7 - c

b = 45.9 - c

The value of b is (45.9 - c)

A study was conducted in order to estimate μ, the mean number of weekly hours that U.S. adults use computers at home. Suppose a

777dan777 [17]

Answer:

The point estimate for $\mu$ is 8.5 hours.

Step-by-step explanation:

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

In this problem

We are working with a sample of 81 adults, so the point estimae of the mean is the mean number of weekly hours that U.S. adults use computers at home.

So, the point estimate for $\mu$ is 8.5 hours.
