Answer:

f(x) = 9x + 4

Step-by-step explanation:

Consider the output values

13, 22, 31, 40, 49

The difference between consecutive terms is constant, that is

22 - 13 = 31 - 22 = 40 - 31 = 49 - 40 = 9

This indicates the function is of the form

y = 9x + c ( where c is a constant )

To find c substitute the values of the input

x = 1 : y = 9(1) + c = 13 → 9 + c = 13 ⇒ c = 4

x = 2 : y = 9(2) + c → 18 + c = 22 ⇒ c = 4

x = 3 : 9(3) + c = 31 → 27 + c = 31 ⇒ c = 4

x = 4 : 9(4) + c = 40 → 36+ c = 40⇒ c = 4

x = 5 : 9(5) + c = 49 → 45 + c = 49 ⇒ c = 4

The value of the constant is 4

Thus the function representing the data is f(x) = 9x + 4

Answer:

A. f(x)=9x+4

Step-by-step explanation:

Function is f(x) =9x+4, because if x=1, then f(1)=9*1+4=9+4=13;

if x=5,then f(5)=9*5+4=45+4=49

Percents
LUCKY_DIMON [66]

Given that,

Michael is leaving a 15% tip for his waitress.

To find,

What percent of the  original price will he pay.

Solution,

Let the original price was 100%.

When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

115\%=\dfrac{115}{100}\\\\=1.15

or

\dfrac{115}{100}=\dfrac{23}{20}

So, this is the required solution.

Dean sot a goal to do more than 900 push-ups this month. So far, he has done 230 push-ups, and there are 20 more days remaining
vampirchik [111]

Step-by-step explanation:

he has 900-230 = 670 more push-ups to do in the remaining 20 days.

so, he has to do every day

670/20 = 67/2 = 33.5 push-ups.

fractions of push-ups don't make sense.

we cannot say, he has to do at least 33 per day, because then he might come short in the end (if he sticks to the low limit) .

so, we have to say he has to do more than 33 or at least 34 push-ups per day to be sure he will at least reach his goal.

p > 33

or

p >= 34

both should be correct in the context of using only whole numbers.

bur in case of doubt I would pick p >= 34.

Specify what an individual unit is in each of the following studies. Then specify what two variables were measured on each unit.
r-ruslan [8.4K]

Answer:

a) Unit: College Student

Variables of measurement: Procrastination and illness habits.

b) Unit: SUV cars

Variables: Manufacturing and car damage for two car manufactures.

Step-by-step explanation:

We are given the following in the question:

In a research, a unit is a single individual or object that is measured.

a) A study finds that college students who often procrastinate tend to be sick more often than students who do not procrastinate.

Since college students are asked about procrastination, then the unit in this study is college students.

Unit: College Student

Variables of measurement: Procrastination and illness habits.

b) A study finds that sport utility vehicles (SUVs) made by one car manufacturer tend to be more heavily damaged in a crash test than SUVs made by a second car manufacturer.

Since all SUVs cars are considered, the unit in this research is  SUV cars

Unit: SUV cars

Variables: Manufacturing and car damage for two car manufactures.
