Answer:
And we want to find this probability:
And we can find this probability:
And using the normal table or excel we got:
Step-by-step explanation:
For this case we have the following info given:
represent the sample size
represent the true proportion
The sample proportion can be approximated with this distribution:
The mean is given by:
And the deviation is given by:
And we want to find this probability:
And we can use the z score formula given by:
And replacing we got:
And we can find this probability:
And using the normal table or excel we got:
Answer:
k = 9.6
Step-by-step explanation:
When dealing with inverse variation, the two variables vary in opposite directions. This means that as the first variable increases, second variable decreases and as the first variable reduces,the second variable increases.
Y varies inversely with x.
So as y increases, x reduces and as y reduces, x increases.
We would proceed by introducing a constant of variation, k
y = k/x
From the information given,
The constant of variation = k
The value if x = 6.4
The value of y = 1.5
To find the value of k
y = k/x
k = yx = 1.5 × 6.4
k = 9.6
Answer
A
Why?
He did not distribute 2/3 to the x
9:20 am
Lcm is 80 so 80 minutes after 8 am is 9:20
