First let us calculate for the z score using the formula:
z = (x – u) / s
where x = 8, u is the mean = 12.7 years, s is the
standard deviation
z = (8 – 12.7) / 2.5
z = -1.88
From the standard probability tables, the p value at z =
-1.88 is:
P = 0.0301 = 3.01%
Answer:
This is the same as writing (x^20)/(y^15)
===================================================
Work Shown:
In the second step, I used the rule that (a*b)^c = (a^c)*(b^c)
In step 3, I used the rule (a^b)^c = a^(b*c)
In the last step, I used the rule a^(-b) = 1/(a^b)
Answer:
can you please give more info?
Step-by-step explanation:
Answer:
4.75 pounds
Step-by-step explanation:
Before the termites: 5 pounds
After the termites: 1/4 of a pound
Amount that the termites took: x
5 - x = 1/4
Add x to both sides of the equation
5 = 1/4 + x
Subtract 1/4 from both sides of the equation
4 3/4 = x
4 3/4 = 4.75
The termites took 4.75 pounds from the log
