Answer: t + 20 = 60; 40 minutes are spent answering phone calls.
Step-by-step explanation: We know that 20 minutes are spent out of a 60 minute day of volunteer work. So, with the equation, t + 20 = 60, we can solve to find out that 40 minutes are spent answering phone calls.
Answer with explanation:
Data set Showing number of times seventh period class attended a summer camp since first grade:
3, 1, 0, 4, 1,⇒⇒Mean =1.8
4, 2, 3, 0, 5,⇒⇒Mean =2.8
0, 1 , 1, 2, 0,⇒⇒Mean =0.8
4, 1, 4, 4, 2,⇒⇒Mean =3
3, 2, 0, 1, 4⇒⇒Mean =2
⇒≡Mean of a Data set is sum of all the variate in data set divided by total number of Variate in the data set.
Range of the sample Means of a data set is difference between Maximum value of variate in the data set and Minimum value of Variate in Data set.
Maximum Value in the sample mean = 3
Minimum Value in the sample mean = 0.8
⇒Range = Maximum value of mean - Minimum value of mean
= 3 - 0.8
= 2.2
⇒≡None of the option given, matches with the value of range Calculated.
Answer:
a = 22
b = 31
c = 13
Step-by-step explanation:
The sum is the same in each row, column, and diagonal.
One of the diagonals is already complete. The sum is:
16 + 25 + 34 = 75
So the first row adds up to 75:
a + 37 + 16 = 75
a = 22
The second row adds up to 75:
19 + 25 + b = 75
b = 31
And the third row adds up to 75:
34 + c + 28 = 75
c = 13
We can check our answer by finding the sum of each column and the other diagonal.
22 + 19 + 34 = 75
37 + 25 + 13 = 75
16 + 31 + 28 = 75
22 + 25 + 28 = 75
