Your answer should be 0.3000
Step-by-step explanation:
I am doing the same math and I have no idea one nobody is helping me :/ there just looking at my problem and saying the wrong number :((
Simplest form would be, 5y-23+72 then it would be 5y+49
Answer:
We can assure the Ann Arbor officials that after look the information we conclude that the mean is 8 h
Step-by-step explanation:
From CI ( 95 % ) = ( 6,7 ; 9,3 )
And the information "large random size sample" we conclude that the population has a normal distribution; a normal distribution has a bell shape curve, and data must spread symmetrically with respect to the mean, therefore the mean is:
6,7 + 9,3 = 16
16/2 = 8
If we need t check we can use the other CI
CI ( 99 % ) = (6,257 , 9,743 )
6,257 + 9,743 = 16
16/2 = 8
We are sure the mean is 8 h
Explanation:
This might not be how you are supposed to do it but,
We can see the two triangles are similar because AA similarity.
We know that the sides are proportional so we can make:
We get,
Because sides can't be negative, x = 2/3
