Answer:

336

Step-by-step explanation:

The formula for a volume of a cylinder is πr²h

The description of the terms:

π = pie = 3.14

r = radius

h = height

One thing to remember in this formula :

πr² is also the formula for the area of a circle

In the figure given, the area of the base, which is a circle, is 48 cm²

Now, we got one of the part in the formula for the volume of the cylinder.

πr²h = volume of cylinder

πr² = 48

48(7) = volume of cylinder

336 = volume of the cylinder

Hope I helped!

The sum of x and 3/5 is 5/7.

crimeas [40]

We first write the word in math as x+3/5 = 5/7. Now we cross multiply our fractions and rewrite them with the LCD of 5 and 7. Our equation now looks like x + 21/35 = 25/35. We simplify our equation by subtracting 21/35 from both sides to get x = 4/35. 4/35 is already in lowest terms so it is our answer.

The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning

Anna11 [10]

4x + 89.95 = 628.35 <== ur equation
4x = 628.35 - 89.95
4x = 538.40
x = 538.40 / 4
x = 134.60 <== the cost for each cavity filling

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.9 years with a

Bas_tet [7]

Answer:

5.9 years.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

In this question:

Mean of the population is $\mu = 5.9$

If a sampling distribution is created using samples of the ages at which 69 children begin reading, what would be the mean of the sampling distribution of sample means?

By the Central Limit Theorem, the same population mean, of 5.9 years.

As a 42.4 foot long pipe comes off the manufacturing line it is cut into 0.80 foot long sections. How many smaller sections are

Ludmilka [50]

53 smaller sections are created from the larger pipe

Step-by-step explanation:

The number of smaller section will be obtained by dividing the length of long pipe by the length of small section.

Given

Length of long pipe= 42.4 feet

Length of small section = 0.80 foot

$Total\ number\ of\ sections=\frac{Length\ of\ large\ pipe}{length\ of\ one\ small\ section}\\=\frac{42.4}{0.80}\\=53$

53 smaller sections are created from the larger pipe
