48 + 36 written as a product of two factors gives; 12 × 7

We are given the function;

48 + 36

Let us pick the largest common factor of both numbers which is 12 and so we will factorize to have;

12*4 + 12*3

⇒ 12(4 + 3)

⇒ 12 * 7

Thus, the correct answer is 12 * 7

The thickness of a fingernail is about 10^-5 inch

From the complete question, we have the following parameter

Thickness = 1/100000 inch

To represent the thickness in standard form, we do the following:

Express the thickness as a decimal

Thickness = 0.00001 inch

So, the standard form would be:

Thickness = 1 * 10^-5 inch

This gives

Thickness = 10^-5 inch

Hence, the complete statement is:

The thickness of a fingernail is about 10^-5 inch

There are 720 different ways to arrange the books.

Here we know that there are a total of 7 books, 3 of math and 4 of sciences.

We know that the 3 math books must be together, so first let's analyze this element.

The number of permutations of these 3 books is 3! = 3*2*1 = 6

Now we have 5 elements, 4 books of science and a "group of math books."

So there are 5 positions in which the group of math books can be, and for the four science books we have 4! = 4*3*2*1 = 24 permutations.

The total number of different combinations is given by the product of the numbers we found above:

combinations  = (permutations of math)*(possible positions of math)*(permutations of science).

Combinations = 6*5*24 = 720

Anasia is a basketball player who regularly shoots sets of 2 free throws. The required standard deviation is 0.65

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

Anasia is a basketball player who regularly shoots sets of 2 free throws. Suppose that each shot has a probability of 0.7, point, and 7 being made, and the results of the shots are independent.

[tex]e \times P(X=x) \\=0\times 0.09+1\times0.42+2\times0.49\\=0.49+0.98\\\\1.4[/tex]

Now,

[tex]E(X^2) = 0\times0.009 +1^2 \times0.42 +2\times0.42\\\\= 0.42+ 1.96\\\\=2.38[/tex]

we can calculate the standard deviation by variance

[tex]\sigma^2 = E(X^2) - (E(X))^2\\\\\sigma^2 =2.38 - 1.4^2\\\\\sigma^2 =0.42\\\\\sigma = 0.65[/tex]

The required standard deviation is 0.65
