Step-by-step explanation:
2(4x - 8) - 10
8x - 16 - 10
|_______|
8x - 26
-5x + 8 - 11x - 12
___ ___ _____ ____
___ ____
-16x - 4
-3(4x - 5)
-12x + 15
For the third and first exercises, you just use the Distributive Property, and for the second exercise, all you are doing is combining like-terms.
I am joyous to assist you anytime.
Let's simpifuy the answer they gave us:
Answer letter C
Q 1:
$8.50+$23.25+$18.00+$10.75+x = 14
_________________________

x+ $60.5 = 14(5)
x+ $60.5= 70
x= 70 - $60.5
x= $9.5#
answer check:
8.50+23 .25+18.00+10.75+9.5

=14 (everage/mean)
Complete question:
A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wishes to test H0: u=175 millimeters versus Ha:u>175 millimeters, using the results of n samples. Find the boundary of the critical region if the type I error probability is and n = 16
Answer:
186.63
Step-by-step explanation:
Given:
Using the standard normal deviate table:
NORMSINV(0.01) = 2.326
Thus, the Z score = 2.326
To find the critical value if the mean, use the formula:
Since we are to find X', Make X' subject of the formula:
The boundary of the critical region is 186.63
