It would be 20, because 5 plus 4 is 9 and you can multiply 9 by 2 to get 18, 9 by 3 to get 27, and 9 by 4 to get 36, but you can't multiply anything by 9 to get to 20.
Answer:
$425
Step-by-step explanation:
because the closest to 400$ is 425. hope this helps
Answer:
y = 14.5
Step-by-step explanation:
given that y varies directly as x
mathematically,
y ∝ x
y = kx .............................................. where k is the constant of proportionality.
k = y /x
given that
y = 79
x = 49
k = 79/49
k = 1.61
to find y when x = 9
from
y = kx
y = 1.61 × 9
y = 14.5
therefore the value of y when x = 9 in ths variation is evaluated to be equals to 14.5
Answer:
47.72% of the completion times is between 73.4 and 88.2 minutes
2.28% of the completion times is at most 58.6 minutes
Step-by-step explanation:
A reading test are normally distributed with a mean time of 73,4 minutes and a standard deviation of 7.4 minutes.

Standard deviation = 
A)Approximately what percent of the completion times is between 73.4 and 88.2 minutes i.e.P(73.4<x<88.2)
Formula : 
At x = 73.4

Z=0
Refer the z table for p value
p value = 0.5
At z = 88.2

Z=2
Refer the z table for p value
p value =0.9772
So,P(73.4<x<88.2)=0.9772-0.5=0.4772
So, 47.72% of the completion times is between 73.4 and 88.2 minutes
B)Approximately what percent of the completion times is at most 58.6 minutes i.e.
?


Z=-2
Refer the z table for p value
p value =0.0228
So,2.28% of the completion times is at most 58.6 minutes
The 2 is __________ the value of the 2 in the number to it's right
Answer:10,000 OR 10
Hope I helped
