Hi Kimberlys969pdrfzz,

Question:

Find the mean

Mean - "The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are."

Solution:

$\frac{10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28}{9} = \frac{180}{9} = 20$

Answer:

Mean = 20

Hope This Helps!

What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-intercept of 2.

spin [16.1K]

Y - 1 = m(x - 1) . . . (1)
y = mx - m + 1 . . . (2)

From(2), -m + 1 = 2 => m = 1 - 2 = -1

Substituting for m in (1), we have:
y - 1 = -(x - 1) . . . (3)

Equation of a line in general form is given by ax + by = c

From (3), y - 1 = -x + 1
x + y = 1 + 1

Therefore, required equation is x + y = 2.

Can someone plz help me. There is an equation and the cost too.

Answer:

C = 40p

Cost for 15 people: 600 dollars

Step-by-step explanation:

The amusement park charges $40 per person.

That can be represented as 40 × P or 40P.

C is equal to the cost of admission for P people.

So, C = 40P

C = 40P

C = 40(15)

C = 600

The cost of admission for 15 people is 600 dollars.

Hope that helps.

Answer: (C) 13,120

Step-by-step explanation:

Given the sequence {4, 12, 36, 108, ... , 8748} we know that the first term (a) is 4 and the ratio (r) is $\dfrac{12}{4}=3$

Input the values above into the Sum formula:

$S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_8=\dfrac{4(1-3^8)}{1-3}\\\\.\quad=\dfrac{4(1-6561)}{-2}\\\\.\quad=\dfrac{4(-6560)}{-2}\\\\.\quad=-2(-6560)\\\\.\quad=13,120$

The density of a certain material is such that it weighs 10 ounces per gallon of volume. Express this density in pounds per pint

poizon [28]

Answer:

0.08 pounds per pint.

Step-by-step explanation:

Given: The density of a certain material is such that it weighs 10 ounces per gallon.

We are to express this density in pounds per pint.

1 gallon ⇒ 10 ounces

1 pound = 16 ounces

How many pounds? = 10 ounces.

Cross-multiplying gives;

$\frac{10 * 1}{16} = 0.625$ pounds

1 gallon = 8 pints

The density in pounds per pint is;

0.625 pounds ÷ 8 pints = 0.078125 pounds per pint = 0.08 pounds per pint (answer rounded up to the nearest hundredth).
