Stephen charges $25 for each lawn he mows. Identify the dependent and independent variable

1 answer:

3 0

Because Stephen always gets $25 it doesn't change making it the Dependent Variable, but how many lawns she mows can change making it Independent.

Dependent = $25

Independent = Lawns Mowed

Ive never did anything like this before, Can someone help?

FromTheMoon [43]

Answer:

Step-by-step explanation:

SA = πr² + πrs

r = 4.42

s = 2.61

SA = π(4.42)² + π(4.42)(2.61)

SA = 19.5364π + 11.5362π

SA = 61.34 + 36.22

SA = 97.56

The closest answer would be A.

Best of Luck!

A certain forest covers an area of 4800 km^2 . Suppose that each year this area decreases by 5.25% . What will the area be after

9966 [12]

Answer:

the area after 6 years is 3,473 km^2

Step-by-step explanation:

The computation of the area after 6 years is as follows:

= Area × (1 - decreased percentage)^number of years

= 4,800 km^2 × (1 - 5.25%)^6

= 4,800 km^2 × 0.9475^6

= 3,473 km^2

Hence, the area after 6 years is 3,473 km^2

A fish story: The mean length of one-year-old spotted flounder, in millimeters, is 127 with standard deviation of 22, and the me

pishuonlain [190]

Answer:

The z-score for this length is of 1.27.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

One-year-old flounder:

Mean of 127 with standard deviation of 22, which means that $\mu = 127, \sigma = 22$

Anna caught a one-year-old flounder that was 155 millimeters in length. What is the z-score for this length

This is Z when X = 155. So

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

$Z = \frac{155 - 127}{22}$

$Z = 1.27$

The z-score for this length is of 1.27.
