Use the regression calculator to compare the teams’ number of runs with their number of wins. a 2-column table with 9 rows. colu

-Dominant- [34]

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956
Sum of Y = 680
Mean X = 661.7778
Mean Y = 75.5556
Sum of squares (SSX) = 50569.5556
Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21

salantis [7]

Answer:

Mean = 83.15

Median = 90

Mode = 88

Range = 110

Outlier = 5

Step-by-step explanation:

Mean - (88+92+76+42+88+90+100+110+115+5+88+92+95)/2 = 83.15

Median - 5, 42, 76, 88, 88, 88, <u>90</u>, 92, 92, 95, 100, 110, 115 = 90

Mode - <u>88</u>, 92, 76, 42, <u>88</u>, 90, 100, 110, 115, 5, <u>88</u>, 92, 95 = 88

Range - 115 - 5 = 110.

Outlier - 88, 92, 76, 42, 88, 90, 100, 110, 115, <u>5</u>, 88, 92, 95 = 5

hope it helps :)

Rudiy27

Answer:

#4= 1

#5= A=9,216

B=360

Step-by-step explanation:

number five x equals 9 and y = 1,024 so it's asking us that if x = 81 what would y = and to get 81 you need to multiply 9 by 9 so all you have to do is multiply 1024 by 9 to get 9,216 so y = 9,216 and the same thing goes for B
