Answer:

15 ways

Step-by-step explanation:

<u>Recall:</u>

nCk=\frac{n!}{k!(n-k)!}

n = Number of items given in a set

k = Number of objects selected from a set of n objects

<u>Given:</u>

n = 6 people

k = 4 chairs

<u>Calculation:</u>

6C4=\frac{6!}{4!(6-4)!}=\frac{720}{24(2)}=\frac{720}{48}=15

Therefore, there are 15 different combinations.

Thе іmagе оf (-2, 5) is (1, 1).
dem82 [27]

Answer:

  (6, -2)

Step-by-step explanation:

To get to x=1 from x=-2, you must add 3 to the x-coordinate. Only one answer choice has an x-coordinate that is 3 more than that of the given point:

  3 + 3 = 6

The image point is (6, -2).

_____

<em>Check</em>

To get from a y-coordinate of 5 to an image point y-coordinate of 1, you must subtract 4. If you subtract 4 from the y-coordinate of (3, 2), you get 2-4 = -2, the y-coordinate in the chosen answer above.

Write 98 as the product of prime factors in ascending order
umka2103 [35]

to write 98 as a product of its prime factors we have to first find the prime factors of 98

prime factors are prime numbers by which the given number can be divided by.

98 we have to keep dividing it by prime numbers

98 is an even number so we can first divide by 2

98 / 2 = 49

49 is a multiple of 7 which too is a prime number so we can divide 49 by 7

49/7 = 7

7 can be divided again by 1

7/7 = 1

98 is divisible by 2 and 7

so 98 written as a product of prime factors is

98 = 2 x 7 x 7
