Answer:

i. 18 miles per hour is an outlier

ii. the outlier decreases the mean speed

Step-by-step explanation:

An outlier in a given data is one of the values that is far greater or lesser compared to others. It affect the mean and standard deviation of a given data significantly.

From the given data, 18 is far too small compared to other values. This is certainly an outlier. This would affect the mean speed by decreasing the value.

An interquartile range is a measure of differences among data by dividing a set of given data into quartile. Increasing the value of the outlier would increase the interquartile range.

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 35

Step 2: Solve for x hits

Substitute [BLF]: 35 = 0.15x - 1.5
Add 1.5 on both sides: 36.5 = 0.15x
Divide 0.15 on both sides: 243.333 = x
Rewrite: x = 243.333

Remember that this is a prediction. According to the best line of fit, we would need approximately ~243 to get 35 home runs.

Alice has two flying disks. One is 12 cm in diameter and the other is 24 cm in diameter. What is the difference between the area

Oksi-84 [34.3K]

Answer:

432π cm² or 1356.48 cm²

Step-by-step explanation:

The area of a circle is πr²

The area of the disks are 144π and 576π.

576π-144π = 432π

432π ≈ 1356.48 cm²

Point G is the centroid of triangle ABC. AG = (5x + 4) units and GF = (3x – 1) units. What is AF? 11 units 15 units 43 units 51

jek_recluse [69]

see the attached figure to better understand the problem

we know that

The point G is where all medians intersect and is often described as the triangle's center of gravity or centroid. It is formed by the intersection of the medians. The centroid divides each median in a ratio of $\frac{2}{1}$

$\frac{AG}{GF} =\frac{2}{1} \\\\ \frac{5x+4}{3x-1}=\frac{2}{1}\\ \\ (3x-1)*2=5x+4\\ \\ 6x-2=5x+4 \\\\ 6x-5x= 4+2\\\\ x=6\ units$

Find the value of FA

$FA=(5x+4)+(3x-1)\\ \\FA=8x+3\\ \\FA=8*6+3\\ \\FA=51 units$

therefore

the answer is

$51 units$
