Which of the following expressions would give the number of ways to choose a group of 7 from a group of 15?

Answers

The formula is ¹⁵C₇. Then the number of ways to choose a group of 7 from a group of 15 will be 6435.

What are permutation and combination?

A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.

Then the number of ways to choose a group of 7 from a group of 15 will be given by the combination formula.

Then we have

Number of ways = ¹⁵C₇

Number of ways = 6435

Which is longer ; 180 seconds or 3 minutes?

Answers

Both 180 seconds or 3 minutes are equal.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

We have two times,

180 seconds and 3 minutes.

180 seconds in minutes,

= 180/60

= 3 minutes.

Therefore, both are the same.

how you find the answer is you divide 60 into 180 and you get 3 which means 3 minutes so their both the same

What is the area of a kitchen floor that measures 15 1/4 feet by 13 3/4 feet?

Answers

Hi there! The area is 209 11/16 square feet. First, you can turn 15 1/4 into an improper fraction which is 61/4.If you don't know how to make an improper fraction, here is what to do: 15 1/4. Multiply the whole number by the denominator.( 15 x 4 = 60) Then you add the numerator.(60 + 1 = 61) The denominator ALWAYS stay the same. Do this same step for 13 3/4. For 13 3/4,you will get 55/4. Now, all you do is multiply!

Answers

Final answer:

In this question, we create a system of inequalities to describe the possible number of hours and distance you may have to drive. It is not possible to have driven 160 miles.

Explanation:

Part A:

Let t represent the number of hours you drive and d represent the distance you drive.

The constraints for the number of hours are: 0 ≤ t ≤ 3, which means you can drive for at most 3 hours.

The constraints for the distance are: 0 ≤ d ≤ 55t, which means the distance you drive cannot exceed 55 miles per hour multiplied by the number of hours you drive.

Part B:

No, it is not possible for you to have driven 160 miles. Let's substitute t = 3 into the distance constraint:

d ≤ 55t

d ≤ 55(3)

d ≤ 165

Since 160 is greater than 165, it is not within the range of possible distances you can drive.

Final answer:

The system of inequalities describing the possible numbers of hours and distance is t ≤ 3 and d = t × 55. It is not possible to have driven exactly 160 miles.

Explanation:

Part A:

To describe the possible numbers of hours and distance you may have to drive, we can create a system of inequalities based on the given conditions. Let's denote 't' as the number of hours you drive and 'd' as the distance you cover.

The maximum allowed driving time is 3 hours, so we can write the inequality: t ≤ 3.

Since your maximum speed is 55 miles per hour, the distance 'd' can be calculated using the formula: d = t × 55.

Combining these two inequalities, we have: t ≤ 3 and d = t × 55.

Part B:

To determine if it is possible to have driven 160 miles, we substitute the distance 'd' with 160 in the inequality: d = t × 55. By solving for 't', we can find the allowed range of hours. Plugging in the values, we get: 160 = t × 55. Rearranging the equation, we find t = 160 / 55, which gives t ≈ 2.91.

Therefore, it is not possible to have driven exactly 160 miles, as it falls outside the allowed range of t.
