Answer:
17000 batteries
Step-by-step explanation:
Three years and one month is equivalent to the mean minus one standard deviation.
Three years and seven months is equivalent to the mean plus one standard deviation.
For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months
Answer:
EH = 10
Step-by-step explanation:
Because F is a midpoint, that means that FG and EF are congruent to each other. So, since FG = 2, that means that EF also equals 2. Because FH also includes FG, you can take the 2 from the FG, and then take that 2 away from 8. Now you know that GH = 6. All that is left is to add all 3 of the units together (2+2+6=10).
The living room is rectangular. We would find the area by applying the formula for calculating the area of a rectangle which is expressed as
Area = length x width
From the information given,
internal length = 5.2
internal width = 2.95
Thus,
internal area of the living room = 5.2 x 2.95
internal area of the living room = 15.34 m^2
You're right, that's the required operation.
Because they want to know how many glasses can be full, the answer is 15.
