To solve this problem, we make use of the z statistic. The formula for the z score is:z score = (x – u) / swhere x is the sample value = 0.90, u is the sample mean = 0.917, and s is the standard deviation = 0.005
Therefore:z score = (0.90 – 0.917) / 0.005z score = -3.4
From the standard probability tables, the p-value for a right tailed test of z = -3.4 is:P = 0.9997
Therefore there is a 99.97% chance that it will be above 0.90 mm
Answer:
Your answer is B
Step-by-step explanation:
Because if they are already $60 and she wants one more it would be $75
Answer:
2(4x^2+1)
Step-by-step explanation:
The greatest common factor of 8x^2 and 2 is 2.
We can factor:
2(4x^2+1)
How did we get the expression in the parentheses?
It is just 8x^2 divided by 2 and 2 divided by 2
Hope this helps!
Lets name the shortest piece a, the medium b and the longest c
Together they are 90inches

The longest is 30 inches longer than the shortest

The third piece is half the lenght of the longest

So if you place c=a+30 in the other 2 equasions you get

And

Now if you put this 2 toghether u get

Multyplied by 2


Meaning that a=18inches
Now that we have the lenght of a we put it in the previous equasion

So b=48/2 which means b=24inches
And together they must be 90 so

C=48inches
