Answer:
you simplify the fractions then you cross multiply
Step-by-step explanation:
1/2 * 4/2 you multiply 1 and 4 and you get 4/4 which is equal to 1
Answer:
The hypothesis test appropriate to be used here is <em>t</em>-test for the difference between two means.
Step-by-step explanation:
In this case, the researcher is interested in the effect of gender bias in hiring, i.e. the researcher wants to determine whether there is any difference in hiring between the male and female candidates.
So the researcher selects 100 fake job application; 50 scientists received an application with a typically male name on top, while the other 50 scientists received an application with a typically female name on top.
The scientists have to rate how likely they were to hire the candidate.
It is provided that the applications were identical other than the name. That is, there are no other factors affecting the hiring of the candidate other than their gender.
After rating the candidates the researcher can compute the mean rating for both the groups.
To determine whether there is any difference between the two means, the researcher can use the <em>t</em>-test for the difference between two means to draw conclusions about the experiment.
Thus, the hypothesis test appropriate to be used here is <em>t</em>-test for the difference between two means.
Answer:

Step-by-step explanation:
Let, the number of blueberry slices = b and number of cherry slices = c.
As, each slice sells for the price of $3.50.
Thus, the revenue of total slices sold = 
Also, the money spent on ingredients of both the pie is $15.25 and $12.84 respectively.
Thus, the total selling cost of the slices = $15.25 + $12.84 = $28.09.
So, we have,
Cindy's profit = Revenue - Cost
i.e. Cindy's profit = 
Hence, the required expression is
.
Answer:
20x^3
Step-by-step explanation:
(I honestly don't have one)
This expression can be written as 4(x+3) because you have to multiply the sum of x and 3 by 4.
Hope this helps
