The table shows the cost of taking a rideshare trip. Which description correctly reflects the way the charges are calculated?
Nadya [2.5K]

The table is an illustration of a linear function.

The description of the charges is: <em>A)  The ride requires a $14 initial fee, plus 50 cents per mile driven</em>

<em />

The base fee is the charges, when the number of miles is 0

From the table;

y = $14, when x = 0

So, the base fee is $14

Next, we calculate the slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

From the table, we have:

m = \frac{16.5 - 14}{5-0}

m = \frac{2.5}{5}

m = 0.5

The above means that:

The cost per mile is $0.5 (i.e. 50 cents)

Hence, the description of the charges is: <em>A)  The ride requires a $14 initial fee, plus 50 cents per mile driven</em>

<em />

Use the following data set to find the standard deviation of the set. 46, 34, 25, 31, 15, 50, 37, 42
vekshin1

The given data exists 46, 34, 25, 31, 15, 50, 37, 42

Mean, μ = 35

Variance, σ² = 114.5

Standard deviation, σ = 10.7004

<h3>What is the standard deviation?</h3>

A standard deviation (or σ) exists as a measure of how dispersed the data exists concerning the mean. Low standard deviation indicates data exist clustered about the mean, and high standard deviation suggests data exist better spread out.

Given data 46, 34, 25, 31, 15, 50, 37, 42

The number of elements exists n = 8 (8 numbers in the set)

To calculate the mean,

(46+34+25+31+15+50+37+42)/8 = 280/8 = 35

μ = 35

To calculate the variance,

Sum of the squared difference between each number of the set and the mean divided by the number of elements of the sample minus one.

Variance = [(46-35)² + (34-35)² + (25-35)² + (31-35)² + (15-35)²+ (50-35)² + (37-35)² + (42-35)²]/8

= 916/8

= 114.5

σ² = 114.5

Standard deviation exists as the square root of the variance.

σ² = 114.5

√σ² = √114.5

σ = 10.7004

Therefore, the standard deviation exists at 10.70.
