Answer: See explanation

Step-by-step explanation:

Correlation is a term which simply measures the strength of the linear relationship that exist between two variables that are quantitative.

In the scenario in the question, since the correlation coefficient between the variables is +0.64, it means that there is a positive correlation between the two variables which means there's a positive relationship between the repeated visits to the coffee shop and the customer's age but they're weakly positively correlated .

Answer:

I would say 54 units (sorry if I'm wrong)

Answer:

12.4 mg

Step-by-step explanation:

a = p(1/2)^(t/h)

p is the initial quantity = 70

t is the time = 15

h is the half life = 6

plug in the givens

a = 70(1/2)^(15/6)

a = 12.3743686708

12.4 mg

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

[tex]A = 4\pi r[/tex]

In which r is the radius.

Volume:

[tex]V = \frac{4\pi r^3}{3}[/tex]

The circumference of the ball is 9.4 inches.

So the radius is:

[tex]6.2832r = 9.4[/tex]

[tex]r = \frac{9.4}{6.2832} = 1.53[/tex]

Surface area

[tex]A = 4\pi(1.53)^2 = 29.3[/tex]

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

[tex]V = \frac{4\pi (1.53)^3}{3} = 14.9[/tex]

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

====================================================

Explanation:

The formula given is

[tex]M = \frac{P*\left(\frac{r}{12}\right)*\left(1+\frac{r}{12}\right)^{12*t}}{\left(1+\frac{r}{12}\right)^{12*t}-1}\\\\[/tex]

which to be honest is a big ugly mess of variables. The fractions also make things even more messy. Through trial and error, you can find various ways to help clean up the formula.

Notice how the "r/12" seems to show up a lot. Let's replace that fraction with the variable A.

So we'll make A = r/12

Because of that, the expression [tex]\left(1+\frac{r}{12}\right)^{12*t}[/tex] turns into [tex]\left(1+A\right)^{12*t}[/tex]

After replacing all the "r/12" terms with "A", we have the formula

[tex]M = \frac{P*\left(\frac{r}{12}\right)*\left(1+\frac{r}{12}\right)^{12*t}}{\left(1+\frac{r}{12}\right)^{12*t}-1}\\\\[/tex]

turn into

[tex]M = \frac{P*A*\left(1+A\right)^{12*t}}{\left(1+A\right)^{12*t}-1}\\\\[/tex]

which is a bit simpler in my opinion.

------------------

We could also let

B = (1+A)^(12t)

which would then allow us to go from this

[tex]M = \frac{P*A*\left(1+A\right)^{12*t}}{\left(1+A\right)^{12*t}-1}\\\\[/tex]

to this

[tex]M = \frac{P*A*B}{B-1}\\\\[/tex]

and that's even more simple

---------------------

We're given the following values

Based on those values, we can say

From here, we plug the values of P, A, and B into the simplified version of the formula below.

[tex]M = \frac{P*A*B}{B-1}\\\\M \approx \frac{75000*0.00191667*1.25832348}{1.25832348-1}\\\\M \approx \frac{180.88431483087}{0.25832348}\\\\M \approx 700.22405563\\\\M \approx 700.22\\\\[/tex]

Step-by-step explanation:

Jacket price= $90

Sales tax= 7%

Sales tax in dollars

=7/100×90

=$6.30

Jacket in cents

=$90+$6.30

=$96.30 ÷100

=$0.9630

Answer:

The p-value of the test is 0.1117 > 0.1, which means that there is not significant evidence at the 10% significance level that the battery life is lower than 1100 hours.

Step-by-step explanation:

A manufacturer reports that the mean lifetime of its lithium batteries is 1100 hours, but there are customer complaints that the battery life is lower.

At the null hypothesis, we test that the mean lifetime of the battery is of 1100 hours, that is:

[tex]H_0: \mu = 1100[/tex]

At the alternate, we test that is is lower, that is:

[tex]H_a: \mu < 1100[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

1100 is tested at the null hypothesis:

This means that [tex]\mu = 1100[/tex]

A consumer advocate group selects 25 of these batteries at random and finds the mean lifetime to be 1080 hours with a standard deviation of 80 hours.

This means that [tex]n = 25, X = 1080, s = 80[/tex]

Test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{1080 - 1100}{\frac{80}{\sqrt{25}}}[/tex]

[tex]t = -1.25[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean below 1080, which is found using a left-tailed test for t = -1.25, with 25 - 1 = 24 degrees of freedom.

With the help of a calculator, this p-value is of 0.1117

The p-value of the test is 0.1117 > 0.1, which means that there is not significant evidence at the 10% significance level that the battery life is lower than 1100 hours.

Answer:

8.66 cm

Step-by-step explanation:

From the diagram :

The vase of the triangle = 9.9cm - 4.9 cm = 5cm

Hence, using Pythagoras rule :

Opposite = √hypotenus² - Adjacent²

Opposite = √10²-5²

Opposite = √100 -25

Opposite= √75

= 8.66 cm

Answer:

Opposite angles are the same measure.

Angles around a point = 360°

When you add all the angles, you get 360.

Angle a and b would measure the same and so would angle d and c. So you double the measure for one of those angles and subtract it from 360.

Then, you half that value( divide by 2) and this is to find the measure of the other angle
