<h2>Answer</h2>

.

A = 9

B = 19

.

<h2>Explain</h2>

.

If median are getting from " ( a + b ) ÷ 2 " . So :

.

Find b :

.

(a + b) ÷ 2 = Median

(17 + b) ÷ 2 = 18

17 + b = 18 × 2

17 + b = 36

b = 36 - 17

b = 19

.

In conclusion, the value of b is 19

.

Find a :

\frac{7 + a + 12 + 15 + 17 + 19 + 20 + 22 + 24 + 25}{10}  = 17

\frac{161 + a}{10}  = 17 \\

161 + a = 17 \times 10

161 + a = 170

a = 170 - 161

a = 9

.

In conclusion, the value of a is 9

.

Margaret has 16 yards of fabric and she is making dresses for z doll write the expression for the length of fabric used for each
emmasim [6.3K]
<h3>The expression for the length of fabric used for each doll is \frac{16}{z}\ yards</h3>

<em><u>Solution:</u></em>

Given that,

Margaret has 16 yards of fabric

she is making dresses for z doll

Therefore,

Total length of fabric = 16 yards

Number of dresses = z dolls

Therefore,

\text{ length of fabric used for each doll } = \frac{ \text{ Total length of fabric }} {\text{ z dolls }}\\\\\text{ length of fabric used for each doll } = \frac{16}{z}\ yards

Thus, the expression for the length of fabric used for each doll is \frac{16}{z}\ yards
