The heights (in inches) and weights (in pounds) of nine randomly selected thirteen-year old girls are listed below. Find the standard deviation for each of the two sample sets of data (rounding to two decimal places), then compare
the standard deviation in heights to the standard deviation in weights.
Heights (inches): 59.1 61.3 62.1 64.7 60.1 58.3
Weights (pounds): 87 94
91
119 96 90
64.6 63.7 66.1
123 98 139

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract
