A student would like to find the height of a statue. The length of the statue's right arm is 54 feet. The student's right arm

Komok [63]

Answer:

a) Approximate height of the statue: 144 feet

b) The approximate height is 1.7% greater that the actual height of the statue.

Explanation

1) Assume that the measures of the statue are proportional to the dimensions of the student. That means:

statue's height student's height

________________________ = ______________________

length of the statue's right arm length of student's right arm

⇒ x / 54 feet = (5 + 1/3) feet / 2 feet

⇒ x = 54 × (16/3) / 2 feet = (54×16) / (3×2) feet = 144 feet

Answer: 144 feet

2) Compare the approximate heigth obtained with the actual height:

144 feet - (143 feet + 9 inches) = 144 feet - (143 feet + 9/12 feet) = 1 feet - 9/12 feet

1 feet - 9/12 feet = 1 feet - 3/4 feet = 1/4 feet.

Hence, the approximate feet obtained is 1/4 feet larger than the actual height.

In relative terms that is : (1/4) / (143 + 3/4) = 0.0017 = 1.7%.

A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.24 lb, the mean of all of the weight

Vladimir [108]

Answer:

a) 3.308 lb

b) That difference is 2.91 standard deviations.

c) $Z = 2.91$

d) We have that $Z = 2.91 > 2$ , so the weight of 5.24lb is significantly high.

Step-by-step explanation:

The z-score formula is given by:

$Z = \frac{X - \mu}{\sigma}$

In which: X is the weight we are going to find the z-score of, $\mu$ is the mean of all the weights and $\sigma$ is the standard deviation of all the weights.

The problems gives these following informations:

The highest weight is 5.24 lb

The mean of all the weights is 1.932 lb

The standard deviation of all the weights is 1.135 lb

a. What is the difference between the weight of 5.24 lb and the mean of the weights?

$D = 5.24lb - 1.932lb = 3.308lb$

b. How many standard deviations is that [the difference found in part (a)]?

The difference found in (a) is 3.308lb.

This can be calculated by a simple rule of three.

1 standard deviation - 1.135lb

x standard deviations - 3.308lb

$1.135x = 3.308$

$x = \frac{3.308}{1.135}$

$x = 2.91$

That difference is 2.91 standard deviations.

c. Convert the weight of 5.24 lb to a z score.

We have that:

$X = 5.24, \mu = 1.932$ and $\sigma = 1.135$ . So:

$Z = \frac{X - \mu}{\sigma} = \frac{5.24 - 1.932}{1.135} = 2.91$
