Phaedra researched the cost of a gallon of milk at eight grocery stores. She recorded her data below. Find the mean cost of a gallon of milk and the mean absolute deviation of the data set. $3.50, $3.50, $2.50, $2.50, $5.00, $2.50, $4.00, $4.50

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
