Noel works as a driver for a transportation company. On average, he drives 152 hours to make 19 successful deliveries. Assume this rate is his
constant rate for delivering goods. If you graph this relationship with time along the x-axis and number of deliveries along the y-axis, the slope of
the line you get gives Noel's unit rate for a successful delivery. Which unit rate can be interpreted as the slope?

Answers

So I have this test too and I'm pretty sure it's 8. I will check back when I know for sure and have my answer submitted.

Edit:

Yes the answer I originally gave is correct.

Noel's unit rate for successful delivery is 1/8 of a delivery per hour option (D) is correct.

What is the rate of change?

It is defined as the change in values of a dependent variable with respect to the independent variables.

The missing options are:

A. 8 deliveries per hour

B. 2/17 of an hour per delivery

C. 1/8 of a delivery per hour

D. 1/8 of an hour per delivery

We have:

On average, he drives 152 hours to make 19 successful deliveries.

The rate is constant.

The total time for which Noel drives = 152 hours

The total number of successful deliveries = 19

Noel's unit rate for a successful delivery

= total successful deliveries/total hours

= 19/152

Divide by 8 on the numerator and denominator:

= 1/8

y = (1/8)x

Here x represents time

y represents the number of deliveries

Thus, Noel's unit rate for a successful delivery is 1/8 of a delivery per hour option (D) is correct.

College roommates John and David were driving home to the same town for the holidays. John drove 55mph, and David, who left an hour later, drove 60mph. How long will it take for David to catch up to John?

Answers

Answer:

sorry

Step-by-step explanation:

It will take for David 11 hours to catch up with John

Speed is the ratio of distance traveled to the total time taken. Speed is given by:

Speed = distance / time

Let d represent the distance at which both John and David meet up at time t hour.

Since drove at 55 mph and is an hour faster, hence:

55 = d / (t + 1)

d = 55t + 55    (1)

John is driving at 60 mph, hence:

60 = d / t

d = 60t    (2)

equating equation 1 and 2:

55t + 55 = 60t

5t = 55

t = 11 hours

Hence, it will take for David 11 hours to catch up with John

A supermarket sells orange juice in three sizes. The 32 fl oz container costs $1.99,the 64 fl oz container costs $3.69, and the 96 fl oz container costs $5.85. Which size orange juice has the lowest price per fluid ounce? Explain!

Answers

Answer:

64 fl oz

Step-by-step explanation:

To find the best price you take the cost and divide it by the number of fluid ounces ($1.99/32). For the 32 oz it costs .062, for the 64 oz it costs .057, and for the 96 oz it costs .060 (these are all approximate number btw). Therefore, since 64 oz has the lowest number it has the lowest price per fluid oz.

A doctor prescribe 125 miligrams of a therapeutic drug that decays by about 10% each hour. Write an exponentia lmodel representing the amount A in milligrams of the drug remainng in the patient's system after t hours.

Answers

Answer:

[tex]C(t)=125\cdot 0.9^t[/tex]

Step-by-step explanation:

Exponential Decay Function

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

[tex]C(t)=C_o\cdot(1-r)^t[/tex]

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The doctor prescribed 125 milligrams of a therapeutic drug. It decays by 10% each hour. The initial value is Co=125 and the decay rate is r=0.1 per hour. Substituting into the function:

[tex]C(t)=125\cdot(1-0.1)^t[/tex]

Operating:

[tex]\mathbf{C(t)=125\cdot 0.9^t}[/tex]

Where t is expressed in hours.

An experiment consists of dealing 6 cards from a standard 52-card deck. What is the probability of being dealt 6 hearts?

Answers

Answer: 0.0000842890

Step-by-step explanation:

Given that :

Number of cards in a deck = 52

Number of hearts in a deck = 13

Probability of being dealt 6 hearts :

Probability = (required outcome / Total possible outcomes)

Required outcome = choosing 6 hearts from a possible 13

13C6:

Recall : nCr = (n! / (n-r)!r!)

13C6 = 13! / (13-6)!6!

13C6 = 13! / 7!6!

13C6 = (13*12*11*10*9*8)/(6*5*4*3*2*1)

13C6 = 1235520 / 730

13C6 = 1716

Total possible outcomes :

52C6 = 52! / (52-6)!6!

52C6 = 52! / 46!6!

52C6 = (52*51*50*49*48*47)/(6*5*4*3*2*1)

52C6 = 14658134400 / 720

52C6 = 20358520

Hence,

P(6 hearts) = 1716 / 20358520

P(6 hearts) = 0.0000842890

5. 24 points scored in 4 games; a points scored in 10 games​

Answers

Complete Question:

24 points scored in 4 games; a points scored in 10 games​. Are they equivalent?

Answer:

Both games are not equivalent

Step-by-step explanation:

Given

[tex]24\ points = 4\ games[/tex]

[tex]1\ point = 10\ games[/tex]

Required

Determine if they are equivalent

We have that:

[tex]24\ points = 4\ games[/tex] ----- (1)

[tex]1\ point = 10\ games[/tex] ----- (2)

To solve this, we simply make the number of games equal.

Multiply (1) by 2.5

[tex]2.5 * 24\ points = 4\ games * 2.5[/tex]

[tex]60\ points = 10\ games[/tex]

This implies that there are 60 points in 10 games

While for (2):

[tex]1\ point = 10\ games[/tex] means that

There are 1 point in 10 games

Hence, both games are not equivalent

Because, the number of points differ in the same number of games

x+2y+−2y=6+−2y

x=−2y+6

Let's solve for y.

x+2y=6

x+2y+−x=6+−x

2y=−x+6
