heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr
Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr
so 24 problems can be done in 1 hr
Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done
and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem
ur answer is : 30 < 24x + 5 < 50 <==
Answer:
12
Step-by-step explanation:
12 doesn't fit the data because it is so much farther from the general average of the others.
12 affects the median because with it, the median is 74. but without 12, the median is 76.
12 affects the mean because with it, the mean is 68.36. but without 12, the mean is 72.69.
Answer:
Step-by-step explanation:
Given that college GPA is positively correlated with salary after college
This means there is a positive linear relationship between GPA and salary after college.
Or we can write one as dependent and another as independent.
Since in the given question Salary is to be found out for given GPA we can make GPA as independent variable and Salary after college dependent variable
We will find a linear relationship as
Salary = slope * GPA + intercept
So
If we use knowledge of a student's GPA to predict his or her salary, the criterion variable is __GPA_____ and the predictor variable is __Salary after college._____.
