Answer:
Claudia could estimate the amount of water that her teammates drank by using this process:
1. Measure the amount that Claudia herself drank.
2. Subtract that from the amount of water that the jug was filled with before the soccer game.
3. Find the difference of that and the current amount of water.

Answer:
The total is: $ 1345.5
Step-by-step explanation:
It is given that:
I would like to purchase 20 products at a cost 65.00 per product.
This means that the cost of 20 products will be:
Also, there is a sales tax of 3.5%
This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.
i.e. he need to pay 3/5% on $ 1300
This means that the amount of tax he need to pay is: 3.5% of 1300
= 3.5%×1300
= 0.035×1300
= $ 45.5.
Hence, the total cost is: $ 1300+$ 45.5
This means that the total cost is: $ 134.5

Check Explanation
Step-by-step explanation:
A) The null hypothesis would be that the proportion of newly hired candidates that are not white is not significantly different from the proportion of the applicants that are not white & there is no significant evidence that the company's hiring practices are discriminatory.
Mathematically,
H₀: μ₀ = 0.53
And the alternative hypothesis would be that there is a significant difference between the proportion of newly hired candidates that are not white is not significantly different from the proportion of the applicants that are not white. More specifically, that the proportion of newly hired candidates that are not white is significantly less than the proportion of applicants that are not white & there is significant evidence that the company's hiring practices are indeed discriminatory.
Mathematically,
Hₐ: μ₀ < 0.53
B) The two errors that can come up in this hypothesis testing include -
Type I error: We reject the null hypothesis because we obtain that the proportion of newly hired candidates that are not white is significantly less than the proportion of applicants that are not white and conclude that there is indeed significant evidence that the company's hiring practices are discriminatory when in reality, there is no significant difference and hence, no discrimination.
Type II error: We accept the null hypothesis (fail to reject the null hypothesis) because we obtained that there is no significant difference between the proportion of newly hired candidates that are not white & th proportion of applicants that are not white and conclude that there is no discrimination in the company's hiring practices when in reality, there is significant difference in the stated proportions above and significant evidence that there is indeed significant evidence that the company's hiring practices are discriminatory.
C) The power of the test increases as the significance level reduces. This is because t-statistic increases as significance level reduces.
D) The standard error of the mean used in computing the t-score is given as
σₓ = (σ/√n)
It is evident that as the value of n increases, the standard error reduces and this widens the effect of the test, hence, the power of the test increases.

Answer:
These are the rectangular prisms that have a surface area greater than 140 square feet
6 feet by 5 feet by 4 feet
7 feet by 6 feet by 4 feet
8 feet by 3 feet by 7 feet
Step-by-step explanation:
The formula to find the surface area of a rectangular prism is SA=2(wl+hl+hw)
All you have to do is go through all the options given to you to figure out which retangular prisms have a surface area greater than 140 square feet.
6 feet by 2 feet by 3 feet
SA = 2((2)(6)+(3)(6)+(3)(2))
SA = 2(12 + 18 + 6)
SA = 2(36)
SA = 72
6 feet by 5 feet by 4 feet
SA = 2((6)(5) + (4)(5) + (4)(6))
SA = 2(30 + 20 + 24)
SA = 2(74)
SA = 148
7 feet by 6 feet by 4 feet
SA = 2((7)(6) + (4)(6) + (4)(7))
SA = 2(42 + 24 + 28)
SA = 2(94)
SA = 188
8 feet by 3 feet by 7 feet
SA = 2((8)(3)+(7)(3)+(7)(8))
SA = 2(24 + 21 + 56)
SA = 2(101)
SA = 202
8 feet by 4 feet by 3 feet
SA = 2((8)(4)+(3)(4)+(3)(8))
SA = 2(32 + 12 + 24)
SA = 2(68)
SA = 136
