$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's use distance formula :

$\qquad \sf \dashrightarrow \: \sqrt{(x - 1) {}^{2} + (2 - 5) {}^{2} } = 5$

$\qquad \sf \dashrightarrow \: {(x - 1) {}^{2} + ( - 3) {}^{2} } = 5 {}^{2}$

$\qquad \sf \dashrightarrow \:(x - 1) {}^{2} + 9 = 25$

$\qquad \sf \dashrightarrow \:(x - 1) {}^{2} = 16$

$\qquad \sf \dashrightarrow \:(x - 1) = 16$

$\qquad \sf \dashrightarrow \:(x - 1) = \pm4$

$\qquad \sf \dashrightarrow \:x = 5 \: \: or \: \: - 3$

A recent national survey found that high school students watched an average (mean) of 7.1 movies per month with a population sta

muminat

Answer:

H0: μc ≤ μs Ha :μc > μs

Step-by-step explanation:

The null and alternate hypotheses can be stated as

H0: μc ≤ μs Ha :μc > μs one tailed test

Where

μc = Mean of college students watching movies in a month

μs = Mean of school students watching movies in a month

For one tailed test of α =0.05 the value of Z= ± 1.645

The critical region will be Z > ± 1.645

It is of importance to note that by rejecting the null hypothesis and accepting the alternate hypothesis we are automatically rejecting all values of mean that are greater than 7.1

If you spend $50,000 on new furniture and it is depreciating about 20% per year, how much will it be worth by its third year?

Julli [10]

Answer:

$25,600

Step-by-step explanation:

Given: P = $50,000, r = 20% & t = 3 years

Formula for depreciation is given as:

$A(t) = P\bigg(1-\frac{r}{100}\bigg)^t$

Plugging the values of P, r and t in the above formula, we find:

$A(3) = 50,000\bigg(1-\frac{20}{100}\bigg)^3$

$\implies A(3) = 50,000\bigg(1-\frac{1}{5}\bigg)^3$

$\implies A(3) = 50,000\bigg(\frac{4}{5}\bigg)^3$

$\implies A(3) = 50,000\times\frac{64}{125}$

$\implies A(3) =\$ 25,600$

So, after third year it will be worth by $25,600.

Carmen measured a house and made a scale drawing. The scale of the drawing was 9 millimeters = 1 meter. What is the drawing's sc

malfutka [58]

When you write a scale factor, the units have to be the same. In this case, 9mm on the drawing represents 1 meter on the house. Change 1 meter to millimeters (1m = 1000mm).

9 mm on the drawing represents 1000 mm on the house.

The scale factor is 9 to 1000, or, as a fraction, 9/1000.
