The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 30 hours and the median is 26.2 hours. Twenty-four of the families in the sample turned on the television for 15 hours or less for the week. The 11th percentile of the data is 15 hours. Step 4 of 5 : What is the value of the 50th percentile?

Answers

Answer 1

Answer:

26.2 hours

Step-by-step explanation:

From the given information:

The objective is to determine the value of the 50th percentile.

The median is the 50th percentile, which categorically divides the data into two equal parts. It is a number separating the higher half of a data sample from the lower half. This implies that the median stands in place for the 50th percentile of the data.

Thus, the 50th percentile value is 26.2 hours

Answers

About 18 inches / 1 foot and 6 inches

If hair grows about 6 inches every year, and we want to find out how much will grow in 3 years, we multiply.

6 x 3 = 18 inches

Then we can simplify it because there are 12 inches in a foot

Answers

Answer: 24100

Step-by-step explanation:

The money in the account after 8 years is $24068.631.

Given that, principal=$19000 and the rate of interest=3%.

What is the formula to find the compound interest?

The formula to find the compound interest is CI=A-P.

Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.

Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]

=19000[tex](1.03)^{8}[/tex]

=19000×1.26677008139

When we evaluate the quotient functions, (mn)(x) for x = -3

(mn)(-3) = 9 and (m/n) (x), x ≠ 0

How did we evaluate the quotient function?

To evaluate the quotient function (mn)(x) for x = -3, we  substituting x = -3 into the function mn(x).

This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.

We then need to evaluate (m/n)(x), x ≠ 0.

This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

And electronics store chain sells headphones The company is about to introduce a new headphones model that is expected to sell very well across its various stores. The projected revenue and cost functions for the headphones are R(x)=-0.25x+25x and c(x)= -17+90. What is the profit function

Answers

Answer:

[tex]P(x) = -0.25x^2 + 42x - 90[/tex]

Step-by-step explanation:

Given

[tex]C(x) = -17x + 90[/tex]

[tex]R(x) =- 0.25x^2 + 25x[/tex]

Required

Determine the profit function.

Profit function is calculated as thus:

[tex]P(x) = R(x) - C(x)[/tex]

So, we have:

[tex]P(x) = -0.25x^2 + 25x -(-17x + 90)[/tex]

[tex]P(x) = -0.25x^2 + 25x + 17x - 90[/tex]

[tex]P(x) = -0.25x^2 + 42x - 90[/tex]
