Answer:

1. 32.5

2. 16.3

Step-by-step explanation:

This is algebra. We need to find the unknown values.

1. 23 = x – 9.5

  Adding 9.5 on both sides of the equation

  23 + 9.5 = x – 9.5 + 9.5

  32.5 = x

∴ x = 32.5

2. 12 = k – 4.3

Adding 4.3 on both sides of the equation

12 + 4.3 = k – 4.3 + 4.3

16.3 = k

∴ k = 16.3

Given that for simplicity that the number of children in a family is 1, 2, 3, or 4, with probability 1/4 each. Little Joe (a boy
horsena [70]

Answer: \dfrac{1}{4}

Step-by-step explanation:

Given : The number of children in a family is 1, 2, 3, or 4.

Little Joe (a boy) has no brothers. But he may have sisters.

The sample space for the number of child in Joe's family : {B, BG, BGG, BGGG}, where G represents girl and B represents boys.

Then , for the probability that he is an only child, favorable outcome = B

Thus, the probability that he is an only child is given by :-

=\dfrac{\text{Favorable outcome}}{\text{Total outcomes}}=\dfrac{1}{4}

Hence, the probability that he is an only child = \dfrac{1}{4}

shusha [124]

Answer:

To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.

2 1/4 + 7/8

The common denominator is 8.

2 2/8 + 7/8

2 9/8

3 1/8

Put back in the 5 ft.

So, Jerry was 5ft and 3 1/8 inches at the end of the school year.

Hope this helped! :)
