PLEASE HELP Complete the table with the number of sit-ups you have to do sunday so that the mean number of sit-ups per day is 10

klemol [59]

The complete table will be:

$Monday - 100\\ Tuesday-65\\ Wednesday- 120\\ Thursday-150\\ Friday-90\\ Saturday- 0\\ Sunday-175$

Explanation

Suppose, the number of sit-ups in Sunday is $x$

Mean is the simple average of some numbers. For finding the mean number of sit-ups per day, we need to divide the 'total number of sit-ups' by the 'total number of days'.

Here the total number of days is 7 and the total number of sit-ups for 7 days $= 100+65+120+150+90+0+x= 525+x$

Given that, the mean number of sit-ups per day is 100. So, the equation will be...

$\frac{525+x}{7}=100\\ \\ 525+x=700\\ \\ x= 700-525=175$

So, the number of sit-ups you have to do Sunday is 175.

Debbie's city took a survey about a plan for a new park. The city surveyed 600 people. 60% of the people surveyed liked the plan

lukranit [14]

Hi there.

All we have to do to find out how many people like the plan is multiplication.

We multiply the total number of people by 60% - in decimal form.

600 · 0.6 = 360

360 people liked the plan.

A. You need to compare 2/5, 1/2 and 3/4
2/5= .4
1/2= .5
3/4=.75
Therefore the bucket that is 2/5 full is less than 1/2 full

Write an integer whose absolute value is greater than itself.

Fed [463]

The set of an integer is called the set Z
The set of integers number is composed by the positive whole number {0, 1, 2, 3…} and the negative whole number {…-4, -3, -2, -1, 0} .We write it as follow Z= {…- 4, -3, -2, -1, 0}U{0, 1, 2, 3…}. If we assume that k is inside Z, so k can be a negative integer of positive integer. Besides the absolute value of a number is always the positive value of this number. Let be k<0 an integer different from zero, so abs(k) >0, and abs(k)> k for all value of k. For example for k= -2, and abs(k)=abs(-2)=2> -2 (always)
