Step-by-step explanation:
The rules is to mutiply pls try your best to do your work rate me 5 thank u hope it help u
First we distribute
into
and
.
That makes the left side of the equation
Now we subtract
from
, which makes
Now the equation is
Our goal is to isolate
, so we both sides by 30
That will make the equation
We multiply -1 on both sides of the equation:
Finally we simplify
, which makes
So the answer is
Answer: 34%
Step-by-step explanation:
Given : The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 7.
i.e. and
According to the 68-95-99.7 rule, about 68% of the population lies in one standard deviation from the mean.
About 34% of the population lies one standard deviation above the mean and About 34% of the population lies one standard deviation below the mean.
For the given situation, 34% of lightbulb replacement requests lies one standard deviation below the mean .
i.e.About 34% of lightbulb replacement requests lies between and .
i.e. About 34% of lightbulb replacement requests lies between and .
i.e. About 34% of lightbulb replacement requests lies between and .
Hence, the approximate percentage of lightbulb replacement requests numbering between 52 and 59 = 34%
The given graph is a Distance- Time graph whose slope gives us speed that is ~ rate of Distance covered ( m ) and per unit time ( sec ).
therefore, the correct choice is ~
No. Make the fractions have a common denominator
1/2=6/12
(Multiply by 6/6, which equals 1)
7/12 is not less than 6/12
