<h3>2 answers: choice B, choice F</h3>

Explanation:

The discriminant is

D = b^2 - 4ac

D = (-5)^2 - 4(3)(-1)

D = 25 + 12

D = 37

This means 37 is under the square root, and we know the answers are B and F due to this. Also note with these two answer choices, they are in the form $\frac{-b \pm \sqrt{D}}{2a}$ where...

a = 3, so 2a = 2*3 = 6
b = -5, so -b = -(-5) = 5

Choices A, C, D, and E can be eliminated as the discriminant for these is D = 13.

Need help Identify three solutions of the graph shown

tester [92]

The solutions are basically the points on the graph that the line passes through. The best way to pick them is to use the whole numbers that are on the corners of the little boxes instead of the middle.

(4, -5)
(3, -3)
(1, 1)
(0, 3)
(-1, 5)
and so on.

"Statewide Insurers receives 1,600 applications per month Currently, there are 160 applications in the Reception area and 240 ap

Inessa05 [86]

Answer:

It takes 5 days to process an application.

Step-by-step explanation:

We have that number of requests per month would be equal 1600

Now, the applications in hand would be:

160 + 240 = 400

They tell us that everything must be in a number of 20 business days, therefore, the number of applications in one day would be:

1600/20 = 80

Which means that the time needed to finish an application is:

400/80 = 5 days

It takes 5 days to process an application.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 18 cm3

Minchanka [31]

Answer:

12 cm³

Step-by-step explanation:

Let's say the radius of the sphere and cylinder is r and the height is h. However, notice that the "height" of the sphere is the same thing as the diameter, which is 2r, so h = 2r.

The volume of a sphere is denoted by: $V=\frac{4}{3} \pi r^3$ , where r is the radius.

The volume of a cylinder is denoted by: $V=\pi r^2h$ , where r is the radius and h is the height. Plug in 2r for h and 18 for V:

$V=\pi r^2h$

$18=\pi r^2*2r=2\pi r^3$

$\pi r^3=18/2=9$

Now plug in 9 for πr³ in the volume formula for the sphere:

$V=\frac{4}{3} \pi r^3$

$V=\frac{4}{3} *9=12$

The volume of the sphere is 12 cm³.

In 1990, the mean duration of long-distance telephone calls originating in one town was 7.2 minutes. A long-distance telephone c

scoundrel [369]

Answer:

We know that In 1990, the mean duration of long-distance telephone calls originating in one town was 7.2 minutes. And we want to test if the mean duration of long-distance phone calls has changed from the 1990 mean of 7.2 minutes (alternative hypothesis) and the complement rule would represent the null hypothesis.

The correct system of hypothesis are:

Null hypothesis: $\mu =7.2$

Alternative hypothesis: $\mu \neq 7.2$

So then the best option for this case would be:

H0: μ = 7.2 minutes Ha: μ ≠ 7.2 minutes

Step-by-step explanation:

The correct system of hypothesis are:

Null hypothesis: $\mu =7.2$

Alternative hypothesis: $\mu \neq 7.2$

So then the best option for this case would be:

H0: μ = 7.2 minutes Ha: μ ≠ 7.2 minutes

And in order to test the hypothesis we can use a one sample t test or z test depending if we know the population deviation or not

X-8pi=pi<br><br><br> plz help (i couldnt find the pi button )

Nostrana [21]

Jus combine like terms. Treat pi like a variable.

x - 8pi = pi

Combine like terms by adding 8pi to both sides to get

x = 9pi
