julia-pushkina [17]

Answer:

g = -1110p +4300.9
804 gallons

Step-by-step explanation:

a) Price is the independent variable, so the data we are given can be written as ...

(price, gallons) = (2.99, 982) and (2.79, 1204)

Using the 2-point form of the equation for a line, we have ...

g = (g2 -g1)/(p2 -p1)(p -p1) +g1

g = (1204 -982)/(2.79 -2.99)(p -2.99) +982

g = -1110(p -2.99) +982 = -1110p +4300.9

g = -1110p +4300.9

b) When p = 3.15, the predicted sales volume is ...

g = -1110(3.15) +4300.9 = 804.4

Weekly sales are predicted to be 804 gallons at a price of $3.15.

A public health department wants to determine the rate that parents of teen boys are choosing to vaccinate their sons for HPV wi

viktelen [127]

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

The sample size is $n = 64$

The proportion that choose to vaccinate the teen boys is $\r p = 0.12$

considering the first statement

The 95% confidence interval is 12% ± the margin of error*standard deviation is false because

The 95% confidence interval is is %12 ± the margin of error

considering the second statement

The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem

np = 64 * 0.12 = 7.68

and this value is less than 10 hence the confidence interval should not be calculated

considering the third statement

A 99% confidence interval will be smaller than the 90% confidence interval is false

This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval

The local pizza parlor is filling an order of 40 pizzas for a school party. The circle graph shows the percentages of the differ

marysya [2.9K]

Answer:

C 10 pizzas

Step-by-step explanation:

We know that there are 40 total pizzas

We also know the percentage of each pizza, except mushroom.

By definition, the total percent of everything is 100%

If we add up what we know...we get the following:

10% Pineapple + 45% Pepperoni + 20% Ham equals 75%

10 + 45 = 55

55 + 20 = 75

If all the pizzas other than Mushroom equals 75% of the pizza toppings, then Mushroom must be 25% of the pizzas

100% - 75% = 25%

25% of 40 pizzas is 0.25 x 40 which equals 10

25% is also the same as 1/4 or one quarter...so 40 divided by 4 is also 10.

So the answer is C. 10 pizzas

Another was to approach this would be to figure out how many of each other pizzas there are.

10% Pineapple is 0.10 x 40 = 4 Pineapple pizzas

45% Pepperoni is 0.45 x 40 = 18 Pepperoni pizzas

20% Ham is 0.20 x 40 = 8 Ham pizzas

if you add 4 + 18 + 8 you get 30 pizzas

40 total pizzas minus 30 non mushroom pizzas leaves 10 mushroom pizzas
