The x intercept ? I think this is what you mean
Answer:
n = 20
Step-by-step explanation:
2n − 35 = 5
find: n
2n = 5 + 35
n = 40 / 2
n = 20
Answer:
The probability of his score being between 135 and 167 is 0.8151 or (0.8151*100=81.51%)
Step-by-step explanation:
Given that:
Mean = μ = 150
SD = σ = 12
Let x1 be the first data point and x2 the second data point
We have to find the z-scores for both data points
x1 = 135
x2 = 167
So,

And

We have to find area to the left of both points then their difference to find the probability.
So,
Area to the left of z1 = 0.1056
Area to the left of z2 = 0.9207
Probability to score between 135 and 167 = z2-z1 = 0.9027-0.1056 = 0.8151
Hence,
The probability of his score being between 135 and 167 is 0.8151 or (0.8151*100=81.51%)
Answer:
26 is the perimeter
Step-by-step explanation:
you add all of the side numbers just like this:
9+5+12= 26 :)
Hope this helped :D
