Suppose that the operations manager of a nose mask packaging delivery service is

Murrr4er [49]

Answer:

Coefficient of variation (weight) = 15%

Coefficient of variation (volume) = 25%

Step-by-step explanation:

Let's begin by listing out the given information:

Population = 200, Average weight = 26 lb,

standard deviation (weight) = 3.9 lb,

Average volume = 8.8 ft³,

standard deviation (volume) = 2.2 ft³

Based on the data given, the manager will have to make a deduction by comparing the relative scatter of both variables due to the different units of measuring weight (pounds) and volume (cubic feet).

To compare the variation of the weight and volume, we use the coefficient of variation given by the formula:

Coefficient of Variation = (Standard deviation ÷ Mean) * 100%

⇒ $C_{v}$ = (σ ÷ μ) * 100%

For weight

σ = 3.9 lb, μ = 26 lb

$C_{v}$ (weight) = (3.9 ÷ 26.0) * 100% = 15%

$C_{v}$ (weight) = 15%

For volume

σ = 2.2 ft³, μ = 8.8 ft³

$C_{v}$ (volume) = (2.2 ÷ 8.8) * 100% = 25%

$C_{v}$ (volume) = 25%

∴ the relative variation of the volume of the package is greater than that of the weight of the package

Laura bernett is 5 ft-4 inches tall. she stands 12 feet from a streetlight and casts a 9-foot-long shadow. how tall is the stree

xxMikexx [17]

The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches

The streetlight is 12 ft 5 1/3 inches tall.

Help please :) What is the value of x? Enter your answer in the box x =

lakkis [162]

Answer:

x=27

Step-by-step explanation:

Triangles always add up to 180 so 90+63+x=180 (we know 90 is one of the degrees because of the triangles next to it) Now do some algebra: 90+63+x=180 add 90+63 together> 153+x=180 minus 153 from both sides it'll be x=27

Need 13&14!! ASAP, will put Brainliest

UNO [17]

Answer:

13- A 14-B

Step-by-step explanation:

You take the formula (x1+x2/2, y1+y2/2) and plug in accordingly. For instance, when you plug the values in for 13, you would get:

x1+-9/2, y1+7/2= -8,2

All you have to do from there is a simple guess and check or plug in each number from the multiple answer choices you have. You should then get A (-7,-3) Do the same with 14, in which you should get B (11,-20)

Sorry for taking so long to answer but hope this kind of helps.
