Answer:

y=18h+0.05s

Step-by-step explanation:

Let's say, y = earnings

h = number of hours worked

s = amount of sales

Mark works at a popular electronics retail store. He earns a fixed income of $18 an hour and a 5% commission on the sales he makes.

Earnings will be the fixed pay plus the commission earned.

So, we have the equation;

y=18h+0.05s

Carter is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Carter will earn
professor190 [17]

Carter's song played on 7 commercials and 5 movies.

Step-by-step explanation:

Earning per commercial = $50

Earning per movie = $130

Total earned = $1000

Total commercial and movies = 12

Let,

x be the number of commercials

y be the number of movies

According to given statement;

x+y=12     Eqn 1

50x+130y=1000    Eqn 2

From Eqn 1

x=12-y    Eqn 3

Putting value of x from Eqn 3 in Eqn 2

50(12-y)+130y=1000\\600-50y+130y=1000\\80y=1000-600\\80y=400

Dividing both sides by 80

\frac{80y}{80}=\frac{400}{80}\\y=5

Putting y=5 in Eqn 1

x+5=12\\x=12-5\\x=7

Carter's song played on 7 commercials and 5 movies.

Most dermatologists recommend using sunscreens that have a Sun Protection Factor (SPF) of at least 30. One of the authors wanted
Basile [38]

Answer:  We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.

Step-by-step explanation:

Given : Significance level : \alpha: 1-0.95=0.05

Sample size : n= 52 , which is a large sample (n>30), so we use z-test.

By using z-value table,

Critical value: z_{\alpha/2}=1.96

Sample mean : \overline{x}= 34.55

Standard deviation : \sigma= 20.12

The confidence interval for population means is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

i.e. 34.55\pm(1.96)\dfrac{ 20.12}{\sqrt{52}}

=34.55\pm5.46867829455\\\\\approx34.55\pm5.4687\\\\=(34.55-5.4687, 34.55+5.4687)=(29.0813,\ 40.0187)

Now, the 95% confidence interval for the ppopulation mean = . (29.0813, 40.0187)

Hence, We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.

What is the distance between the points R (5,7) and S (-2,3) 1: 25 2:33 3:55 or 4:65
Shtirlitz [24]
d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}
d = \sqrt{(-2 - 5)^{2} + (3 - 7)^{2}}
d = \sqrt{(-7)^{2} + (-4)^{2}}
d = \sqrt{49 + 16}
d = \sqrt{65}

The answer is 4, √(65).
