A. A worker with 1700 hours of training is paid $40 per month

Step-by-step explanation:

Given : the table of hours of training and monthly pay

To find : meaning of h(40)=1700

Answer : here 40 is given under hours of training and 1700 is given under monthly pay.

So, h(40)=1700 means the workers with 40 hours of training is paid $1700 every month

The distance between two cities is 87 km. What is the distance between them on a map drawn at a scale of 1:600,000?

Elena L [17]

The distance between them on a map at a scale 1 : 600,000 is 14.5 cm

Step-by-step explanation:

Scale drawing:

Is used to represent a real object with accurate sizes reduced or enlarged by a certain amount (called the scale)
States the ratio of a length in the drawing to an equivalent length in the real world
1 : 100 means 1 unit in drawing represents 100 units in real life

∵ The distance between two cities is 87 km

∵ The distance between them on a map drawn at a scale of

1 : 600,000

- That means each 1 cm represents in real life 600,000 cm, so

you must change the kilometer to centimeter

∵ 1 km = 100,000 cm

∴ 87 km = 87 × 100,000 = 8,700,000 cm

Now let us use the ratio method

→ 1 : 600,000

→ x : 8,700,000

By using cross multiplication

∴ x × 600,000 = 1 × 8,700,000

- Divide both sides by 600,000

∴ x = 14.5

∴ The distance between them on the map = 14.5 cm

The distance between them on a map at a scale 1 : 600,000 is 14.5 cm

vladimir2022 [97]

Answer:

Sample space=S={HH1,HT1,TH1,HH2,HT2,TH2,HH3,HT3,TH3,HH4,HT4,TH4}

Step-by-step explanation:

The sample space for Y can be made as under

Coin is tossed two times={HH,HT,TH,TT}

4-sided die is rolled={1,2,3,4}

Coin is tossed two times and 4-sided die is rolled

={HH1,HT1,TH1,TT1,HH2,HT2,TH2,TT2,HH3,HT3,TH3,TT3,HH4,HT4,TH4,TT4}

Y be the random variable that the number of heads observed multiply by die roll number so, the sample space for Y would be

Sample space=S={HH1,HT1,TH1,HH2,HT2,TH2,HH3,HT3,TH3,HH4,HT4,TH4}

The cost to ride a ferris wheel is $2.00 per person. The ferris a wheel has a capacity of

irakobra [83]

Answer:

When we have a function f(x), the domain of the function is the set of all the inputs that "work" (Not only in a mathematical way, the context is also important) with the function f(x)

In this case, we have a function M(p) = $2*p

This function represents the amount of money collected depending on the number of people who ride on the ferris whell.

Then p can be only a whole number (we can not have 1.5 people, only whole numbers of people).

And we also know that the maximum capacity of the ferris is 64 people.

Then:

p ≤ 64

And we also should add the restriction:

0 ≤ p ≤ 64

(Because p can't be smaller than zero)

Such that p should also be an integer, then, the domain is:

D: p ∈ Z, p ∈ {0, 1, 2, ..., 64}
