Let s denote the quantity of sports drinks purchased by April

Let p symbolize the amount of pizza slices bought by April

Since she spent a total of $21.25, the equation can be stated as:

s+p=21.25

p+3+p=21.25

2p=18.25

p=9.125

As she ordered 3 more sports drinks than pizza slices, we have s = p + 3

Full Question

April bought some sports drinks and slices of pizza for her friends. She bought 3 more sports drinks than slices of pizza. If her total order was 21.25, how many sports drinks did she purchase? One slice of pizza costs 2.25, and a sports drink costs 1.25.

Solution -

Let the total number of pizza slices purchased be X

Then the total number of sports drinks purchased would be X + 3

Given -

Cost of one slice of pizza = 2.25 dollars

Cost of one sports drink = 1.25 dollars

The total cost for X slices of pizza and X + 3 sports drinks would be

X * 2.25 + (X+3) * 1.25 = 21.25

2.25 X + 1.25 X + 3.75 = 21.25 \\3.5 X = 21.25 -3.75\\3.5 X = 17.5\\X = \frac{17.5}{3.5} \\X = 5

Thus, the count of pizza slices purchased equals 5

Consequently, the number of sports drinks acquired is

5 + 3\\8

A researcher is interested in determining if the more than two thirds of students would support making the Tuesday before Thanks
zzz [12365]
The null hypothesis is stated as, {H₀}: p = 0.66, H₀: p = 0.66. The alternative hypothesis can be represented as, {Hₐ}: p > 0.66, Hₐ: p > 0.66. For clarity, let p denote the fraction of students that support making the day before Thanksgiving a holiday. Since we are evaluating two different populations, it is necessary to articulate the alternative hypothesis concerning the difference in their means. The ratio indicating that two-thirds of the students support this holiday is p = 0.66, derived as follows: The null hypothesis is, {H₀}: p = 0.66, H₀: p = 0.66. In contrast, the alternative hypothesis is, {Hₐ}: p > 0.66, Hₐ: p > 0.66.
