Answer:
AC = 15
Step-by-step explanation:
Use segment addition postulate to add AB + BC = AC. 10 + 5 = 15.

Answer:
42.57
Step-by-step explanation:
10+39+71+39+76+38+25=298
298/7=42.57
Answer: t _(α/2) = 2.060
Step-by-step explanation:
Given that;
sample size n = 26
confidence interval = 95%
level of significance α = ( 1 - 95/100 ) = 0.05
but from the question the salaries (26) are use to estimate the mean of the population so, its a two tail test
therefore our level if significance α will be divided by 2 = 0.05/2 = 0.025
now our degree of freedom df = 26 - 1 = 25
FROM standard t-table value
the critical value of t for the level of significance 0.025
and 25 degree of freedom is 2.060
therefore, t _(α/2) = 2.060
Answer:
A
5(15x-4)^3
Explanation:
I assume you mean g(f(h(x))) so in that case here is how you do it:
So the first one is g(x) which is:
5x^3
Now g(f(x)) you just plug in f(x) for the x in the g equation. It would look like this:
5(5x-4)^3
Now the h(x) you would do the same, plug it in for all the values of x in g(x). So it would look like this:
5(5(3x)-4)^3
Since you simplify, you get 5(15x-4)^3
This final equation is g(f(h(x))) which is what you were looking for, which is A
A, just divide by 4 and youll get your solution.
