Step-by-step explanation:
The provided information are:
Population mean 
= 500
Population standard deviation 
= 40
z-score = 2
The formula to calculate the z-score is:
x = data item.
The data item can be computed as:
Hence, the data item is 580.

Answer:
A = Full bottle can fill 34 ounces water and 27.2 ounces left in the bottle
Step-by-step explanation:
Full bottle: 100%
6.8 ounces: 20%
100% / 20% = 5
Full bottle = 6.8 x 5 = 34 ounces
water remain in bottle = 34 -6.8 = 27.2 ounces
B = Answer:
55% or 27.2 ounces
Step-by-step explanation:
If he poured out another 25% out of the 80% percent that was there he would have 55% or 27.2 ounces.
Answer:
<h3>
The number is 7</h3>
Step-by-step explanation:
x - a certain number
6x - - six times the number
6x-31 - six times the number less 31
3x - three times the number
3x-10 - 10 subtracted from three times the number
so the equation:
6x - 31 = 3x - 10
+31 +31
6x = 3x + 21
-3x - 3x
3x = 21
÷3 ÷3
x = 7
Check: 6•7-31=42-31=<u>11</u>; 3•7-10=21-10=<u>11</u>
Answer:
Since the diagonals of a rhombus bisect each other, the diagonals are 5 * 2 = 10 and 12 * 2 = 24. To find the area of a rhombus we can divide the product of the diagonals by 2 which is 10 * 24 / 2 = 120 cm².
