Answer:

Slope of line s is $\frac{2}{5}$

Step-by-step explanation:

It is given line r is parallel to line s .Parallel lines do not meet if produced on either side.

Slope of parallel lines are same .

In the given figure line r is having a slope of $\frac{2}{5}$

Line s is parallel to line r ( given)

Hence line s will have the same slope as line r.

Slope of line s= slope of line r= $\frac{2}{5}$

Answer:

Pvalue = 0.020335

X² = 14.99

CONCLUSION: THERE IS DIFFERENCE IN MARKET SHARES

Step-by-step explanation:

H0 : there is no difference in market shares

H1: there is difference in market shares

Chisquare (X²) = (observed - Expected)²/ expected

Honda Civic - 0.20 * 400 = 80 : (98-80)^2 /80 = 4.05

Toyota Corolla - 0.17 * 400 = 68 : (72-68)²/68 = 0.235

Nissan Sentra - 0.12 * 400 = 48 : (54-48)²/48 = 0.75

Hyundai Elantra - 0.10 *400 = 40 : (44-40)²/40 = 0.4

Chevrolet Cruze - 0.10 * 400 = 40 : (42-40)²/40 = 0.1

Ford Focus - 0.08 * 400 = 32 : (25-32)²/32 = 1.531

Others - 0.23 * 400 = 92 : (65-92)²/92 = 7.924

X² = (4.05+0.235+0.75+0.4+0.1+1.531+7.924) = 14.99

The obtain the Pvalue ;

We use the Pvalue from Chisquare calculator :

Pvalue(14.99, 0.05, df= 6) = 0.020335

Decision region :

Reject H0 ; if Pvalue < α

THERE IS DIFFERENCE IN MARKET SHARES

Market share differences:

* 98/400 = 0.245,

0.245-0.20 = 0.045

* 72/400 = 0.18,

0.18 - 0.17 = 0.01

* 54/400 = 0.135,

0.135 - 0.12 = 0.015

* 44/400 = 0.11,

0.11 - 0.10 = 0.01

* 42/400 = 0.105

0.105 - 0.10 = 0.005

* 25/400 = 0.0625

0.0625-0.08 = -0.0175

* 65/400 = 0.1625

0.1625 - 0.23 = -0.0675

Scale a rectangle that has length 9 inches and width 17 inches by the scale factor determine the dimensions of the scaled rectan

emmasim [6.3K]

Answer:

The dimensions of the scaled rectangle are

$6.3\ in$ of length by $11.9\ in$ of width

Step-by-step explanation:

we know that

The scale factor is equal to $70\%$

Remember that

$70\%=70/100=0.70$

The scale factor is less than 1

the dilation is a reduction

To find the dimensions of the scaled rectangle multiply the dimensions of the original rectangle by the scale factor

$9*0.7=6.3\ in$

$17*0.7=11.9\ in$
