Answer:
2/7
Step-by-step explanation:
The quotient ==> -16/-56 = 2/7 | 8/8 = 2/7
A common factor of -8 can be cancelled from the numerator and the denominator
Make an equation:
5x+12=6x
Use the subtraction property:
x=12
The final answer is that the cost for members and nonmembers will be the same when there have been 12 classes.
Answer:
The first quartile of the IQ scores of adults is 82.26.
Step-by-step explanation:
The first quartile is the value that is greater than 25% of the observations and less than 75% of the observation.
The formula to compute the first quartile (Q₁) of a Normal distribution is:

The mean and standard deviation of the IQ scores of adults are:

Compute the first quartile value as follows:

Thus, the first quartile of the IQ scores of adults is 82.26.
3/5 x 3/5
=9/25
You have to multiply the 2 numerators (top) and then the 2 denominators (bottom)
The median is the middle number when the numbers are put in ascending order (lowest to highest)
1, 2, 3, 4, 4, 7
The middle numbers are 3 and 4. The number between 3 and 4 is thus the median - this number is 3.5
