Answer:
The table is missing in the question. The table is provided below.
Step-by-step explanation:
1. In the table, it is given the difference of high temperature. They are :
-7, -7, 2, 5, -3, -2
Now adding the differences of high temperatures and taking out its average.
-7 + (-7) + 2 + 5 + (-3) + (-2)= -12
Average :
Thus the answer is an integer.
2. In the table, it is given the difference of high temperature. They are :
0, -3, -7, -1, 1, 0
Now adding the differences of high temperatures and taking out its average.
0 + (-3) + (-7 )+ (-1) + 1 + 0= -10
Average :
Thus, the answer is not an integer. The answer lies between the integers -2 to -1.
My present age - x
Mom's age - 2x + 12
My age after 8 yrs - x +8
My mom's age after 8 years - 2x+20
Equation formed-
3(x+8)-20 = 2x+20
3x +24 -20 = 2x +20
x = 20-4 = 16
Therefore, my present age = x = 16 yrs
And my mom's present age = 2x + 12 = 32+12 = 44
The complete table will be:
<u><em>Explanation</em></u>
Suppose, the number of sit-ups in Sunday is
Mean is the simple average of some numbers. <u>For finding the mean number</u> of sit-ups per day, we need to <u>divide the 'total number of sit-ups' by the 'total number of days'</u>.
Here the total number of days is 7 and the total number of sit-ups for 7 days
Given that, the mean number of sit-ups per day is 100. So, the equation will be...
So, the number of sit-ups you have to do Sunday is 175.
Answer:
Yes
Step-by-step explanation:
It might take a while but if you just multiply a number by itself to get the perfect square it would work.
