The members of Maggie's choir have a mean height of 58 inches, with a standard deviation of 4 inches. The choir includes both ch

Inessa [10]

Answer:

Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.

Step-by-step explanation:

Chebyshev's Theorem states that, in a sample:

75% of the measures are within 2 standard deviations of the mean

89% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 58

Standard deviation = 4

Between what two heights does Chebyshev's Theorem guarantee that we will find at least approximately 89 % of the choir members?

Within 3 standard deviations the mean, so from 3 standard deviations below the mean to 3 standard deviations above the mean.

3 standard deviations below the mean

58 - 3*4 = 46

3 standard deviations above the mean

58 + 3*4 = 70

Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.

Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5

y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)

y = 4/5x - 3.6 ( y = mx + b formula)

4/5 = 0.8

y = 0.8x - 3.6

x = 1
y = 0.8(1) - 3.6
y = - 2.8

x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2

x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2

x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4

x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4

etc.

graph using the (x,y)

connect the dots

hope this helps
