Answer:
Choice D
Step-by-step explanation:
38/4 =9.5
Therefore, this number is between 9 and 10
Note:
38/4 = 9 remainder 2
Hence, the quotient is 9 which is a whole number
The area of the figure above is 53
Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32
Answer:
6x+2y+3=0
Step-by-step explanation:
y=-3x-(3/2) add 3x
y+3x=-(3/2) divide -1
-y-3x=3/2 multiply 2
-2y-6x=3 subtract 3
-2y-6x-3=0 multiply -1
2y+6x+3=0 rearrange
