14n+ 4 = 2( 7n + 2 ) ; the factors are 2 and ( 7n + 2 ) ;
Answer:
The value of M would be 18
Step-by-step explanation:
It's 18 because if we do 5 x 14 x 18 it would give us 1,260 cm
Answer:
24
Step-by-step explanation:
Equilateral has 3 angles that add up to 180, and all angles are equal
3(2x+12) = 180
6x+36 = 180
180-36 = 6x
144 = 6x
24 = x
Answer:
The approximate percentage of SAT scores that are less than 865 is 16%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 1060, standard deviation of 195.
Empirical Rule to estimate the approximate percentage of SAT scores that are less than 865.
865 = 1060 - 195
So 865 is one standard deviation below the mean.
Approximately 68% of the measures are within 1 standard deviation of the mean, so approximately 100 - 68 = 32% are more than 1 standard deviation from the mean. The normal distribution is symmetric, which means that approximately 32/2 = 16% are more than 1 standard deviation below the mean and approximately 16% are more than 1 standard deviation above the mean. So
The approximate percentage of SAT scores that are less than 865 is 16%.
