Answer:

They would be normally distributed.

Step-by-step explanation:

Because there are more than 30 samples, the distribution would closely resemble the normal distribution.

40 ticketholders are winning the contest. 40 ≥ 30. This is enough to make the distribution approximately normal.

Answer:

12 gallons

Step-by-step explanation:

If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.

Answer:

(1,-1)

Step-by-step explanation:

We can solve the system by using substitution.

In order to do this we must make x the subject in the first equation.

We can do this by simply subtract 2y from both sides

x + 2y = -1

subtract 2y from both sides

x + 2y - 2y = -1 - 2y

simplify

x = -2y - 1

now that we have made x the subject in one of the equations we can plug in (or substitute) the value of x into the other equation

2x – 3y = 5

x = -2y - 1

2(-2y - 1) - 3y = 5

We can then solve for y

2(-2y - 1) - 3y = 5

Distribute the 2

-4y - 2 - 3y = 5

combine like terms -4y + -3y

-7y - 2 = 5

add 2 to both sides

-7y = 7

divide both sides by -7

y = -1

Now that we have found the value of y we can plug in the value of y into one of the equations and solve for x

x + 2y = -1

y = - 1

x + 2(-1) = -1

multiply 2 and -1

x + -2 = -1

add 2 to both sides

x = 1

So we have found that x = 1 and y = -1 therefore the solution to the system of equations is (1,-1)
