Horace is a professional hair stylist.
let c represent the number of child haircuts and a represent the number of adult haircuts that horace can give
within 7 hours
0.75c +1.25 a < 7
horace gave 5 child haircuts. how many adult haircuts at most can he give with the remaining time?

2

Step-by-step explanation:

0.75(5)+1.25(a)<7

3.75+1.25(a)<7

1.25(a)<3.25

a<2.6

therefore Horace can give 2.6 more haircuts but you can't do 2.6 of a haircut so with the remaining time he can do 2.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.

step-by-step explanation:

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
