Which is equal to the product of HJ?

1 answer:

7 0

H = 1st row 4 -2 5
2nd row 6 1 -3

J = 1st column 7 3 8

1st row and 1st column: 4*7 + -2*3 + 5*8 = 28 - 6 + 40 = 62
2nd row and 1st column: 6*7 + 1*3 + -3*8 = 42 + 3 - 24 = 21

Answer is 2nd option. 62 and 21.

Given:
3 kids
72 is the product of their ages.
There is a youngest child.

This means that all three are of different ages. We need to factor 72 into 3 integers.
Let us use prime factorization:

72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3

Prime factors are: 2 x 2 x 2 x 3 x 3 OR 2³ x 3²

3 ages.

eldest = 3³ = 9
middle = 2² = 4
youngest = 2¹ = 2

2 x 4 = 8
8 x 9 = 72

Answer:

Therefore, the probability is P=1/84.

Step-by-step explanation:

We have a bag contains 3 red and 6 white tokens. Tokens are randomly selected and removed one at a time until the bag is empty.

We conclude that in a bag have 9 tokens.

We calculate the probability that the red tokens are drawn consecutively.

We calculate the number of possible combinations:

$C_3^9=\frac{9!}{3!(9-3)!}=84\\\\$

Number of favorable combinations is 1.

Therefore, the probability is P=1/84.
