Answer:
-29/2
Step-by-step explanation:
the expression that is equivalent is 7^6*7^1
We use the formula:
x± s <span>t_<span>(1−c)/2 / </span></span>√n = 5
(1 - c)/2 = (1 - 0.95) / 2 = 0.025
Using the t score calculator at this value, at the 95% confidence internval,
t = 0.5080, So
100 - 19(0.5080) / √n = 5
Solving for n
n = 97
a) 97
b) yes
I'm sorry but I don't understand what "distributive property" and "properties of equality" means - English isn't my native language.
But the value of x is 30
0,5 * (30 + 6) = 18
True To my knowledge well
