a university is comparing the grade point averages of biology majors with grade point averages of engineering majors. the university wants to test whether there is a significant difference in the hpa for students in the two majors what are the null and alternative hypotheses that should be used to test this claim
Answers
Answer:
H0 : μEng = μBio
H1: μEng ≠ μBio
Step-by-step explanation:
μEng = Engineering average gpa
μBio = Biology average gpa
To test for difference between two sample means , in this case grade point average of biology majors and Engineering major.
Null hypothesis is the initial truth, which is that ; there is no difference in the mean grade point average of both biology and engineering majors
H0 : μEng = μBio
The Alternative hypothesis is the opposite of the null, which is stated has ; there is difference between the average GPA of both Engineering and Biology majors
H1: μEng ≠ μBio

x:y=5:3 and x+y=56 work ouy the value of x and y
Answers
Answer:
x=35, y=21
Step-by-step explanation:
A way to rewrite the first equation is [tex]\frac{x}{y} =\frac{5}{3}[/tex]
after cross-multiplying, we get 3x=5y.
If we solve for one variable, we can substitute it into the other equation.
Let's solve for x.
3x=5y
x=(5/3)y
Now, we can substitute x=(5/3)y in the equation x+y=56.
(5/3)y+y=56
(8/3)y=56
y=21
Going back to x+y=56, we can now plug back in y, knowing that it is 21.
x+21=56
x=35.

One acre is equivalent to 43,560 square feet. If an acre is also equivalent to 4,840 square yards, how many square feet are equal to one square yard? Add an explanation and a step by step answer.
Help please thank you so much! (Math has never really been my strongest subject)
Side Note: I'd rather not have the answer in a file thank you very much.
Answers
Answer:
9 square feet
Step-by-step explanation:
1 acre = 43,560 ft²
1 acre = 4,840 yd²
Since both values are equal to 1 acre, we can set them equal to each other via the property of equality:
43,560 ft² = 4,840 yd²
The question is asking us to find the ft²/yd² ratio, which is found by dividing.
43,560 ft² / 4,840 yd² = 9 ft²/yd² (or 9 square feet is equal to one square yard.)
(If it helps to grasp the concept, we can add a variable representing this ratio to solve for.)
43,560 = 4,840x
43,560 / 4,840 = 9
