Hope this helps you

Step-by-step explanation:

43. A "Square" cornfield, which means all 4 sides has the same lenght BxH

164.000 ft^2=404.96 NO

156.816 ft^2=396 Yes

174724 ft^2=418 Yes

215908 ft^2=464.66 NO

44. it's the same here, if the area is 81. then each side of the square is 9

1st figure: it has 12 sides x9 =108

2nd figure: it has 10 sides x9=90

3rd figure: has also 12 sides x9=108

45. 13^3= 13x13x13 = 2197

46. 25^2= 25x25 = 625

47. 15^3= 15x15x15 = 3375

48. 34^2= 34x34 = 1156

49. 5 root121= 5 (11)=55

50. -6.root36= - 6 (6)= -36

51. 10 root3 (8) = 10(2) = 20

52. -4. root 144= -4(12) = -48

The total amount shared by the friends illustrates mean and average, and the amount spent by each friend is $11.5

<h3>How to determine the amount?</h3>

The given parameters are:

Total = $76
Tip = $16
Number of friends = 8

The amount spent by each friend is calculated using:

Amount = (Total + Tip)/Number of friends

So, we have:

Amount = (76 + 16)/8

Evaluate

Amount = 11.5

Hence, the amount spent by each friend is $11.5

A driving school wants to find out which of its two instructors is more effective at preparing students to pass the state’s driv

jonny [76]

Answer:

Yes, there is evidence to support that claim that instructor 1 is more effective than instructor 2

Step-by-step explanation:

We can conduct a hypothesis test for the difference of 2 proportions. If there is no difference in instructor quality, then the difference in proportions will be zero. That makes the null hypothesis

H0: p1 - p2 = 0

The question is asking whether instructor 1 is more effective, so if he is, his proportion will be larger than instructor 2, so the difference would result in a positive number. This makes the alternate hypothesis

Ha: p1 - p2 > 0

This is a right tailed test (the > or < sign always point to the critical region like an arrowhead)

We will use a significance level of 95% to conduct our test. This makes the critical values for our test statistic: z > 1.645.

If our test statistic falls in this region, we will reject the null hypothesis.
