When would there be only four different equations for a set of math mountain numbers?

Mathematics

Trava [24]3 years ago
5 0

Answer:

Only when any equation you find among those numbers can be simplified into one of the four main equations, which means you only have four different true statements and lots of equivalences. 20 = 40 - 20. As the two addends are the same, so there would be only four different equations for a set of math mountain numbe

Sarah earns $500 a week at her job when she works 40
frez [133]

Answer:

G = $612.50 when H = 46hours

Step-by-step explanation:

Given:

G = 18.75(H-40) + 500

Where,

G =Gross pay in dollars

H = Number of hours worked

If her gross pay one week was $612.50, what was the

total number of hours she worked that week?

G = $612.50 when H = ?

G = 18.75(H-40) + 500

612.50 = 18.75H - 750 + 500

612.50 = 18.75H - 250

Add 250 to both sides

612.50 + 250 = 18.75H

862.5 = 18.75H

Divide both sides by 18.75

862.5 / 18.75 = 18.75H / 18.75

46 = H

H = 46

If her gross pay one week was $612.50, her total hours worked = 46hours

A manufacturer knows that their items have a normally distributed length, with a mean of 16.2 inches, and standard deviation of
statuscvo [17]

Answer:

57.926%

Step-by-step explanation:

Calculation for the probability that it is less than

16.4 inches long

Using this formula

z = (X - μ) / σ

Where,

X represent Date=16.4

μ represent Mean=16.2

σ represent Standard deviation=0.9 inches

Let plug in the formula

z = (16.4 - 16.2) /0.9 inches

z=0.2/0.9 inches

z = 0.2

Using Z-score table to find the area of 0.2

z=0.57926*100

z=57.926%

Therefore the probability that it is less than

16.4 inches long is 57.926%
