Two figures are similar. The ratio of the corresponding sides between the figures is 9 to 12 (9:12). Based on the ratio, which could be the scale factor used to dilate one figure to create the other?

Step-by-step explanation:

1. the claim here is that over 60 percents of the households living in ann harbor have pets.

null hypothesis;

h0: p≤0.60

alternative:

h1: p>0.60

2.

n is the size of the sample = 280

n(p) = 280 x 0.60 = 168 greater than 10

n(1-p) = 280(1-0.6) = 280 x 0.4 = 112  greater than 10

we use the normal dist since each of the above are greater than 10

3. n = 280

x = 182

x/n = 182/280

= 0.65

we get the test statistic z

z = [tex]\frac{0.65-0.6}{\sqrt{0.6*(1-0.6)/280} }[/tex]

= [tex]\frac{0.05}{\sqrt{0.000857} }[/tex]

=[tex]\frac{0.05}{0.02927}[/tex]

≈ [tex]1.71[/tex]

we get the p value = 1-p(z<1.71)

= 1-.9562

this gives 0.0438

4. we can see that 0.0438 < 0.10

so we conclude that over 60% of these households have at least one pet since we rejected h0.

Given:

A composed figure of a rectangle, semicircle and another semicircle removed.

To find:

The area of the given figure.

Solution:

From the given figure it is clear that the diameter of semicircle and removed semicircle are same, i.e. 8 cm.

Since the diameter of semicircle are equal, therefore their area is also equal.

The area of the given figure is:

A = Area of the rectangle - Area of removed semi circle + Area of semicircle

A = Area of the rectangle - Area of semicircle + Area of semicircle

A = Area of the rectangle

We know that, the area of a rectangle is

[tex]A=length\times width[/tex]

The length of the rectangle is 14 units and width is 8 units. So, the area of composed figure is

[tex]A=14\times 8[/tex]

[tex]A=112[/tex]

Therefore, the area of the combined figure is 112 sq. units.

Answer:

$54

Step-by-step explanation:

300 times 0.06 times 3

0.06 times 3 = 0.18

300 times 0.18 = 54

The simple interest is $54

Answer:

$54

Step-by-step explanation:

A = P(1 + rt)

300(1 + (0.06 × 3)) = 354

Answer:

y=5x-11

Step-by-step explanation:

parallel lines have the same slope 5

y-4=5(x-3)

y-4=5x-15

y=5x-15+4

y=5x-11

Answer:

The answer is "[tex](p-1) (pq-r^2)[/tex]"

Step-by-step explanation:

Given:

[tex]\to P ^2q-pr^2-pq+r^2\\\\[/tex]

Rearrange the above value:  

[tex]\to P ^2q-pr^2-pq+r^2 = p^2q-pq-pr^2+r^2\\\\[/tex]

                                    [tex]= pq(p-1)-r^2(p-1)\\\\= (p-1)(pq-r^2)\\\\[/tex]

Answer:

1) = 32.02

2) = 18

Step-by-step explanation:

1) 20^2 + 25^2 = 1025

sq rt 1025 = 32.02

2) 30^2 - 24^2 = 324

sq rt 324 = 18

Answer:

27π

Step-by-step explanation:

area of circle = πr^2

= π × 6^2

= 36π

36/4

= 9

36 - 9

= 27π units squared

Answer:

13

Step-by-step explanation:

71-6=65

65/5=13

therefore the answer is 13

5d + 6 = 71

5d = 71 - 6

5d = 65

d = 65/5

d = 13

Answer:

[tex] \huge \boxed{ \boxed{\tt y < - 2x + 7 }}[/tex]

Step-by-step explanation:

let's figure out the slope

two points (2,3),(0,7)

[tex]m = \frac{ 3 - 7 }{ 2 - 0}[/tex]

[tex]m = \frac{ - 4}{2} [/tex]

[tex]m = - 2[/tex]

y-intercept:7

therefore

our linear inequality is
