Answer is 12, they spilt 1/5 on the way to the lemonade stand 180 x 1/5 = 180/5 = 36 so they spilt 36 cups of lemonade on the way to the stand number of cups left 180- 36 = 144. They sold 75% of 144 cups of lemonade 75/100 x 144 (divide both 75 and 100 by 25) = 3/4 x 144 (divide 144 by 4) =3 x 36 = 108 so they sold 108 cups of lemonade number of cups left 144-108 = 36 they spilt 1/3 of 36 cups of lemonade on the way home. 36 x 1/3 = 36/3 = 12 therefore they brought back 12 cups of lemonade home.

Answer:
C. Type I error
Step-by-step explanation:
Hello!
The hypothesis tested was:
H₀: μ = 7
H₁: μ > 7
The decision was taken: Reject the null hypothesis.
Reminder:
There are four decisions you can take when you make a hypothesis test.
1. Reject the null hypothesis when the hypothesis is false (This is a correct decision)
2. Reject the null hypothesis when the hypothesis is true (This decision is also known as Type I error)
3. Fail to reject the null hypothesis when the hypothesis is true (This is a correct decision)
4. Fail to reject the null hypothesis when the hypothesis is false (This decision is also known as Type II error)
Since they concluded, that the average process time vas greater than 7 days, when it was 7 days, they rejected the null hypothesis when it was true. This is a Type I error and its associated probability is α.
I hope it helps!
Answer:
d
Step-by-step explanation:
In order for the two triangles to be similar the ratio of each side has to be the same. in answer do the ratios would be 21 to 17.5 and 18 to 15 and both ratios equal 1.2 which means they are similar triangles.
