Answer:
Explained
Step-by-step explanation:
Given that:
- A researcher is interested in determining whether a large aerospace firm is guilty of gender bias in setting wages.
According to the given info the difference in means test is too limited because it does not include the type of engineer, education level or experience. The gender with lower wages of might be reflected in the type of engineer or education level.
The research could be improved using additional data on the factors namely gender, education, education and the type of engineer.
Then, further it is recommended to construct a multiple regression where the dependent variable is a wage and the four factors are independent variables. The importance of the omited variable by the means of that the "difference in means" test in unsuitable for determining the gender bias in setting wages.
Answer:
Thomas travels <em>64 miles each hour</em>.
Step-by-step explanation:
Distance traveled by train = 328 miles
Time taken to travel by train =
We know that speed can be formulate as:
Speed is equal the total distance traveled for the one unit time.
In our case, speed is total distance traveled in miles in 1 hour.
So, using above formula:
As per definition of Speed, Thomas travels <em>64 miles each hour</em>.
X = 1st evening, y = 2nd evening, z = 3rd evening
x + y + z = 83
x = z + 7
y = 2z
z + 7 + 2z + z = 83
4z + 7 = 83
4z = 83 - 7
4z = 76
z = 76/4
z = 19 <=== 3rd evening calls
x = z + 7
x = 19 + 7
x = 26 <=== 1st evening calls
y = 2z
y = 2(19)
y = 38 <=== 2nd evening calls
Answer:
25, 29
Step-by-step explanation:
The Pythagorean Theorem is a² + b² = c² where a and b are legs and c is the hypotenuse. In this case, a = 2, b = 5 and we are solving for c, which is also known as AC here. Therefore,
4 + 25 = AC²
AC² = 29
