69 cm is one standard deviation below the mean
<span>for a normally distributed (bell curve) population </span>
<span>___ about 68% lie within one standard deviation of the mean ___ 34% above and 34% below </span>
<span>in this case , the 34% below the mean is added to the 50% above the mean (the 1/2 of the population equal to or longer than 79 cm) </span>
<span>so 84% of the population is longer than 69 cm</span>
Answer:
86°
Step-by-step explanation:
Given:
A = (6x + 10)°
B = (4x +30)°
Two angles are supplementary if they sum up to 180° ;
A + B = 180°
Now insert the parameters and solve;
6x + 10 + 4x +30 = 180
10x + 40 = 180
10x = 140
x = 14
So;
B = (4x +30)° = 4(14) + 30 = 86°
A. They need to be sure you will be able to pay the loan back
You would be able to read 36 pages in 45 minutes
Here's how i got it.
You divide 16/20 = 0.8
Take 0.8 and multiply it by 20 to get 16. (Always good to check your work)
Then you would take 0.8 and multiply by 45 in order to get your final answer of 36 pages.
Hope this helped!
