Step-by-step explanation:
1.2x=6. So first you divide 1.2 on both sides like: 1.2/1.2 and 6/1.2. so then you get x alone and the equation is x=5.
Answer: 3.125
Step-by-step explanation:
Given
Triangle is dilated by a factor of 
i.e. each side multiplies to 0.25.
Side E'F' becomes 0.25 times the original length
Answer: 56-(7+5)
Step-by-step explanation:
You can find the amount of muffins left over by adding up the amount of muffins that were eaten and subtracting them from the original amount of blueberry muffins, so the answer is 56-(7+5).
(7+5 is in parentheses because if not, you would have 56-7+5 and get 54).
A. we use the z statistic to solve this problem
z = (x – u) / s
We calculate the value of the sample mean u and standard deviation
s:
u = $30 * 304 = $9120
s = $21 * 304 = $6384
z = (9,600 – 9120) / 6384
z = 0.075
From the normal tables using right tailed test,
P = 0.47
B. At worst 11% means P = 0.11, so the z value at this is
z = -1.23
-1.23 = (x – 9120) / 6384
x = 1267.68
