Answers

Answer 1
Answer:

The formula for the cost, C of renting a car as a function of the number of days, d, and the number of miles driven, m is C f(d, m) = 40 + 55d + 0.13m

Given:

Application fee = $40

cost per day = $55

cost per mile = $0.13

let

Total cost = C

Number of days = d

Number of miles = m

Total cost, C = 40 + 55d + 0.13m

C f(d, m) = 40 + 55d + 0.13m

= 40 + 55(5) + 0.13(600)

= 40 + 275 + 78

= $393

Therefore, the cost of renting the car given the number of days is $393

Answer 2
Answer:

Answer:

A) C(d,m) = 40 + 55d + 0.13m

B) $448

Step-by-step explanation:

Let 'd' be the number of days and 'm' the number of miles driven.

A) The cost function that describes a fixed amount of $40, added to a variable amount of $55 per day (55d) and a variable amount of 13 cents per mile (0.13m) is:

B) If  d = 5 and m =600, the total cost is:

The cost is $448.

a fair coin tossed in the air four times if the experiment probability of landing on tails is 1/4,then what is the difference between the experimental and theoretical probability

Answers

The difference between the experimental and theoretical probability is 1/4.

Given that

A fair coin is tossed in the air four times if the experimental probability of landing on tails is 1/4.

We have to determine

What is the difference between the experimental and theoretical probability?

According to the question

The experimental probability is 1/4 because of the four times the coin was flipped, it only landed on tails once, and on heads the other three times.

The theoretical probability, however, is 1/2 because there are two possible outcomes that are equally likely.

The theoretical probability is one that can be calculated without having to do the experimental trials following all the steps given below.

Then,

The difference between the experimental and theoretical probability is,

Hence, the difference between the experimental and theoretical probability is 1/4.

Also how would you round 2.59 to the nearest tenths ?

Answers

Answer:

2.6

Step-by-step explanation:

The tenths digit is the 5.

Drop every digit after the 5. You get 2.5

Now you need to see if the 5 stays as it is or if it goes up by 1 to 6.

The first digit after the 5 you dropped is 9. Since 9 is greater than 4, the previous digit goes up by 1, so the 5 becomes a 6.

The final answer is 2.6

Answer:

2.6

Step-by-step explanation:

When rounding, if the decimal place after what you are rounding is ≥5, you round up. ≤4, you dont do anything.

Example:

6.37 rounded to the nearest tenth is 6.4 because the 7 in the hundredths place is ≥5

5.32 rounded to the nearest  tenth is 5.3 because 2 is ≤5 so we do nothing.

In our problem:

2.59 rounded to the nearest 10th is 2.6 because 9 is ≥5 so we round up.
