10 times as many as a number is 10 × the number.
10 times as many as 1 ten is 10 × 10 = 100
10 times as many as 1 hundred is 10 × 100 = 1000
Therefore, 10 times as many as 1 hundred is 10 hundreds or
10 times as many as 1 hundred is one thousand.
To answer (a), we will need to find the Z value for 710 hours and 990 hours.
B) 68% of data lies between one standard deviation of the mean.
850 +70 = 920
850 - 70 = 780
Answer:3x+6=2x+21 base angle of isosceles triangle
3x-2x=21-6
X=15
<J=3×15+6=51
<k=2×15+21=51
,<I=180-51-51=78
Step-by-step explanation:
Answer:
54minutes
Step-by-step explanation:
Let the time taken to clean up be t
Let the number of people cleaning be n
If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;
t = k/n
k is the constant of proportionality
If 3 people work together to clean, and took them 90 minutes, this means
at t = 90, n=3
Substitute
90 = k/3
k = 3×90
k = 270
To et the time it will take 5people to clean, the will say;
t =k/n
t =270/5
t = 54 minutes
Hence it will take 5 people 54minues to clean
