So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be $(1.07*2+0.85*2+2.12*2)$

Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is $7(1.07*2+0.85*2+2.12*2)$ . Now we can solve it from there.

Firstly, solve the multiplication inside the parentheses: $7(2.14+1.7+4.24)$

Now add up what's inside the parentheses: $7(8.08)$

Lastly, multiply and <u>your answer will be $56.56</u>

Answer:

Distance is 6.7units to the nearest tenth.

Explanation:

To solve this problem, we the distance formula. And this is given as:

$D = \frac{|a x + b y + c|}{\sqrt{a^2 + b^2}}$

We were given the equation:

y = 2 x + 4

This can also be rewritten as:

y – 2 x – 4 = 0.

Therefore, a = -2, b = 1 and c = -4

Also, we were given the points:

(x, y) = (–4, 11)

Making use of the above formula for distance, we have:

$D = \frac{|-2\times -4 + 1\times 11 + -4|}{\sqrt{-2^2 + -4^2}}$

$D = \frac{15}{\sqrt{5}}$

D = 6.7units (to the nearest tenth)

Ber [7]

Answer:

No. The data in this study were not based on a random method. This is a key requirement for an inference to be made from the two-sample t-test.

Step-by-step explanation:

1. Hayden can use the two-sample t-test (also known as the independent samples t-test)to find out if there was a difference in the time spent in the checkout time between two grocery stores and to conclude whether the difference in the average checkout time between the two stores is really significant or if the difference is due to a random chance. There are three conditions to be met when using the two-sample t-test.

2. The first condition is that the sampling method must be random. This requirement was not met in this study. Each customer from each store should have an equal chance of being selected for the study. This was not achieved.

3. The distributions of the sample data are approximately normal. This is achieved with a large sample size of 30 customers selected for each study.

4. The last but not the least condition is the independence of the sample data. Sample data here is independent for both samples.
