Quick help 20 points Michael charges $5 an hour to babysit.

Which of the following expresses the amount of money Michael gets paid as a function of how many hours he babysits?

f( x) = x + 5
f( x) = x
f( x) = 5 x
f( x) = x/5

the first one f(x)=x+5

Step-by-step explanation:

f(x) = 5x

Step-by-step explanation:

Because Michael is working at $5 dollars an hour to babysit:

1 hour: $5

2 hour: $10

Alright. So if Michael makes this ratio, and we have x hours, he would make 5 times that amount of hours in money. (5 is the multiplication factor).

Therefore, f(x) = 5x

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
