Is it practical to list all of the different possible routes in order to select the one that is​ best?
A.
​Yes, it is practical to list all of the different possible routes because the number of possible permutations is very small.
B.
​Yes, it is practical to list all of the different possible routes because the number of possible permutations is very large.
C.
No, it is not practical to list all of the different possible routes because the number of possible permutations is very small.
D.
No, it is not practical to list all of the different possible routes because the number of possible permutations is very large.

Answers

Answer:

P (She selects the route of four specific capitals) = (1)/(2686320)=(3.7226)10^(-7)

D. No,it is not practical to list all of the different possible routes because the number of possible permutations is very large.

Step-by-step explanation:

Let's start assuming that each route is equally likely to be chosen.

Assuming this, we can calculate P(A) where the event A is ''She selects the route of four specific capitals'' doing the following :

P(A) = Favourable cases in which the route of four specific capitals is selected / Total number of ways in 4 of 42 states

The favourable cases in which the route of four specific capitals is selected is equal to 1 .

For the denominator we need the permutation number of 4 in 42.

The permutation number is defined as :

nPr=(n!)/((n-r)!)

42P4=(42!)/((42-4)!)=(42!)/(38!)=2686320

The probability of event A is : (1)/(2686320)=(3.7226)10^(-7)

Finally for the other question : The option D is the correct because the number of possible permutations is 2686320 and is very large to be listed.

Find the difference of 5.95 and 4.7

Answers

Answer:

1.25 is your answer.

Final answer:

To find the difference between 5.95 and 4.7, we subtract 4.7 from 5.95, following the rules of subtraction involving decimals, giving us the result of 1.25.

Explanation:

The question asks us to find the difference of 5.95 and 4.7. This can be easily done by using the subtraction operation. Here, since 5.95 is greater than 4.7, we subtract 4.7 from 5.95.

To solve this, follow these steps:

  • First, align the numbers by their decimal points: 5.95 - 4.7
  • Since you cannot subtract 7 from 5, you would need to borrow 1 from the number in the next decimal place to the left, i.e., 9.
  • Now subtract the numbers in each decimal and whole number place: (15 - 7) and (4 - 4).
  • After performing the subtraction, you get your answer, 1.25.

Therefore, the difference between 5.95 and 4.7 is 1.25.

Suppose the correlation coefficient between a predictor variable (a person’s height, measured in centimeters) and a response variable (a person’s weight, measured in kilograms) is 0.72.Suppose that we change the units used to measure height from centimeters to inches and the units used to measure weight from kilograms to pounds, and then we recompute the correlation coefficient. Which of the following would be true?Select one:a. The new correlation coefficient should be the same: R = 0.72.b. The new correlation coefficient should be R = 0.72 × (2.54/2.2) ≈ 0.83.c. The new correlation coefficient should be R = 0.72 × (2.2/2.54) ≈ 0.62.d. The new correlation coefficient should be something other than the options given here.

Answers

Answer:

a) The new correlation coefficient should be the same: R = 0.72

Step-by-step explanation:

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

It is a relative dimensionless measure, so it does not depend on the units of measurement of the variables involved.

If the variables are correlated in centimeters and kilograms, they will also be correlated in inches and pounds, and with the same relative magnitude.

So the answer is  

a) The new correlation coefficient should be the same: R = 0.72

Ethan buys 4 packs of muffins. He uses a Coupon and saves $2 off the total.Which expression represents his total cost?

A. 4+2

B. 4m -2

C. 4m + 2

D. 4 - 2m

​

Answers

This expression represents Ethan's Total cost after using the coupon cost after using the coupon would be:4m - 2

Ethan buys 4 packs of muffins. He uses a coupon and saves $2 off the total.

Let's find out which expression represents his total cost.

Step 1: Determine the cost of one pack of Muffins

To determine the cost of one pack of muffins, we need to use algebra.

Let m be the cost of one pack of muffins. If Ethan buys 4 packs of muffins, then his total cost before using the coupon would be 4m.

Step 2: Use the coupon to calculate the total Cost Now let's use the coupon to calculate Ethan's total cost.

We know that he saved $2 off the total.

Therefore, his total cost after using the coupon would be:4m - 2

This expression represents Ethan's total cost after using the coupon. Therefore, the correct answer is option B: 4m - 2.
