<em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>0</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
1% of students in 7th grade ----- 10 ÷10= 1 student
<em>×</em><em>100</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

Answer:
Step-by-step explanation:
One
The input is the top line. B is the output when multiplied by 4
B = 4A
Input A 12 15 47 34
Output B 48 60 188 136
Rule: 12 * 4 = 48; 15*4 = 60
Check the other two.
Two
B = A/2
Input A 44 56 18 26 20
Output B 22 28 9 13 10
Rule: 44/2 = 22; 56/2 = 28
Check the others.
I highly recommend using the unit circle; the answer is 1/2.
Answer:
The probability is 0
Step-by-step explanation:
Since proportion of time spent on mowing will be 200/400 = 0.5, there will be no chance that the true proportion of time spent mowing is exactly equal to the sample proportion. Where true proportion is 200 and sample is 400 . So the probability is 0.
What u have to do it combine the like terms on each side, so the answer is y=13+7 or y=21
