Percent of children under five considered to be underweight. Percent of Underweight Children Number of Countries 16–21.45 23 21.45–26.9 4 26.9–32.35 9 32.35–37.8 7 37.8–43.25 6 43.25–48.7 1 What is the best estimate for the mean percentage of underweight children? What is the standard deviation? ( consider this sample data ( not population data ) Consider that unusual values are typically more than 2 standard deviations ( ±2sx ) from the mean. Therefore, which interval(s) could be considered unusual? Explain.

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
