Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are:<em> 7, 14, 21, 28, 35. </em>You can get these by multiplying 7 to any integer.
- 7x1 = 7
- 7x2 = 14
- 7x3 = 21
- 7x4 = 28
- 7x5 = 35
In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21
<em>The answer is 21.</em>
Answer:
a = 4, b = 
Step-by-step explanation:
Use any ordered pairs of points from the table.
Substitute into the equation and solve for a and b, that is
Using (0, 4), then
4 = a
= a
Hence a = 4
Using (2, 1), then
1 = 4
( divide both sides by 4 )
b² = 
( take the square root of both sides )
b =
Equation is
y = 4
I hope the joke wasnt attented but the answer is 69
Answer:
0.43
Step-by-step explanation:
It's easy if you think of 43% as a decimal if you base it off 100. For example lets write a fraction about it: 
. A decimal you can think of the same way. 0.43 is the same as saying 43% of 100 or 43/100.
