Mathematics
1 answer:
IRISSAK [1]3 years ago
6 0

Answer:

50.6

Step-by-step explanation:

MA=46.2-14=32.2

We have similar triangles.

That is, triangle MNP is similar to MAB.

This means, we have the following proportion to solve:

32.2/46.2=x/72.6

Multiply both sides by 72.6

32.2/46.2*72.6=x

50.6=x

Select all of the equations that have graphs with the same y-intercept (starting amount).
attashe74 [19]

Answer: y=3x-8, y=5x-8, and y=2x-8

Step-by-step explanation:

These equations are all lines in slope-intercept form (y=mx+b where b is the y-intercept). y=3x-8, y=5x-8, and y=2x-8 all have -8 as the b value. Therefore, these equations have the same y-intercept.

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of
Lesechka [4]

Answer:

680 students

Step-by-step explanation:

The 68 - 95 - 99.7  rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean,  95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

number of people that like MATH 123 = 0.68 * 1000

number of people that like MATH 123 = 680 students
