Please solve number 11:(​
MrRa [10]

Answer:

Market price $400

Cost price $300

Step-by-step explanation:

MP: market price

CP: cost price

1. (MP x 0.9) - CP = 60

CP = 0.9MP - 60

2. MP - CP = 100

CP = MP - 100

0.9MP - 60 = MP - 100

MP - 0.9MP = 100 - 60

0.1MP = 40

MP = 400

Cost price = MP - 100 = 400 - 100 = 300

zysi [14]

Answer:

The percentile rank of someone who earns $75,000 per year is the 85th percentile.

Step-by-step explanation:

Meaning of percentile:

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

In this question:

Working population of 10,500

8,925 people earn less than $75,000 per year.

8925/10500 = 0.85

0.85*100 = 85

The percentile rank of someone who earns $75,000 per year is the 85th percentile.

What is the equation of the line that passes through the point (2, -1) and has a<br> slope of 3/2
quester [9]

Answer:

y = 3/2x - 4

Step-by-step explanation:

y = mx + b

*plugging in slope*

y = 3/2x + b

*finding b (aka y-intercept, starting value, when x=0) by plugging in x and y values from point (2, -1) )*

-1 = 3/2 * 2 + b

-1 = 3 + b

b = -4

so: y = 3/2x - 4
