Answer:
A. 10%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
The new number is the increased wage, $8.25, and the old number is the original wage, $7.50.
percent change = ($8.25 - $7.50)/($7.50) * 100%
percent change = ($0.75)/($7.50) * 100%
percent change = 0.1 * 100%
percent change = 10%
Since the percent change is a positive number, it is a percent increase.
The percent increase was 10%.
Answer: A. 10%
Answer:
30
Step-by-step explanation:
Here, it is given that the Z – score corresponding to the score X = 45 is 1.5 and the Z – score corresponding to the score X = 40 is...
Z =
So:
1/ 1.5 = and 1 = . solve the both equations, we found out:
<=> S = 10
=> M = 30
Hence, mean is:
M = 45 -1.5S = 45 - 1.5 (10) = 30
Answer: There are children at the circus show.
Step-by-step explanation:
Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.
Knowing that of the spectators are men, we can find the remaining:
Since of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:
Solving for "x", we get:
Therefore, we get that "c" is:
Answer:
x = 10 and y = 7
Step-by-step explanation:
Equalateral triangle means all sides are equal.
x = 10, easy
make y + 3 = 10
y = 7
Easy, no real math needed. lol
