7. Brenda is the owner of Brenda's Hair Salon. She produced the following graph to show that her customers are more satisfied than customers of two nearby salons owned by Nancy and Tammy. Which statement best describes why the graph is misleading?

Brenda's ratings look better than they really are because the graph does not start at zero. Using percentages makes it seem like there is a large difference in customer satisfaction between Brenda's Hair Salon and its competitors. Not enough salons were included in the survey.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
