Answer:

x=11

Step-by-stepx+11 explanation:

this was an accident ignore this

It isn't appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.

The major reason is because the sample is short and it is given that most consumer has zero payouts.

The size of the sample taken is not enough large. When sample isn't large enough, it represents skewed information of the population.

The population itself contains many customers who have zero payouts, thus the population isn't normally distributed for insurance claim.

Because of these reasons, the sample mean won't help in deducing conclusions about population mean.

Thus, it is inappropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.

It is not appropriate to perform a hypothesis test for the mean payout of all customers, mostly because the sample is really small.

The first thing you can see is the sample size, it seems to be really small for a company with thousands of customers, is really probably that just 18 of them do not represent accurately the whole population.

We also do know that a large proportion of the population has zero payouts, so the population is skewed.

Just because of these two motives, the mean of the sample most likely does not accurately portray the whole population, thus is not appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.

Answer:

49 tickets

Step-by-step explanation:

THis is pretty straight forward

So we have the ratio 4:7

We know there were 88 tickets in total but we don’t know the exact amount of adult and kids

So we can Add up the ratio

4+7=11

Now we can divide 88 by 11

you’ll get 7

So by doing this we know there are 7 groups of the ratio for child to adults 4:7

So we just multiply the 7 to each

4*7

7*7

you’ll get 28:49

Now we know there are 28 kid tickets and 49 adult tickets

We know this is correct becuase if you add up the ratio, it’ll be 88

Which is the same as the amount fo people at the hockey game

Answer:

1 hour and 15 minuets

Step-by-step explanation:

5 hours and he was hedging for 25% of that time.

25%=.25

5(0.25)

1.25

A quarter of an hour is 15 minutes.

So the final answer would be 1 hour and 15 minuets.

Answer:

Step-by-step explanation:

(-8x + 2) + (-5x + 7)

-8x + 2 - 5x + 7

- 13x + 9

Finding x:

We know that the diagonals of a rhombus bisect its angles

So, since US is a diagonal of the given rhombus:

∠RUS = ∠TUS

10x - 23 = 3x + 19                      [replacing the given values of the angles]

7x - 23 = 19                                [subtracting 3x from both sides]

7x = 42                                       [adding 23 on both sides]

x = 6                                           [dividing both sides by 7]

Finding ∠RUT:

We can see that:

∠RUT = ∠RUS + ∠TUS

Since we are given the values of ∠RUS and ∠TUS:

∠RUT = (10x - 23) + (3x + 19)

∠RUT = 13x - 4

We know that x = 6:

∠RUT = 13(6)-  4

∠RUT = 74°

Answer:

Step-by-step explanation:

For your first question,

Total percentage of people cheering for visiting team = 45%

Total percentage of people cheering for home team = 55%

Total number of people cheering = 1200

Therefore, the number of people cheering for visiting team = 45% of 1200

                                                                                                   = [tex]\frac{45}{100}[/tex] × 1200

                                                                                                   = 45 × 12

                                                                                                    = 540 people

For your second question,

Total number of questions = 75

Total percentage of the number of questions he completed = 36%

Percentage of the amount of questions left = 100 - 36 = 64%

Therefore, the number of questions left to complete = 64% of 75

                                                                                 = [tex]\frac{64}{100}[/tex] × 75

                                                                                 = [tex]\frac{64}{20}[/tex]  × 15

                                                                                 = [tex]\frac{64}{4}[/tex] × 3

                                                                                 = 16 × 3

                                                                                 = 48 questions are left

Answer:

a. 8.5

b. 10

Step-by-step explanation:

a.) 1, 1, 2, 7, 7, 10, 12, 16, 20, 34

Since 7 and 10 are tied in the middle, then we need to find a number in the   middle of the two.

8.5 is in the middle of 7 and 10, therefore 8.5 is the mean.

b.) We need to do the same thing we did before, except add 22 to it's directed place:

1, 1, 2, 7, 7, 10, 12, 16, 20, 22, 34

Since 10 is in the middle, 10 is the new mean.

Answer:

a) The slope of the function is 3.

c) The equation is represented by [tex]n(t) = 3\cdot t + 35[/tex].

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

[tex]n(t) = m\cdot t + n_{o}[/tex] (1)

Where:

[tex]m[/tex] - Slope, measured in number of pieces per minute.

[tex]t[/tex] - Time, measured in minutes.

[tex]n_{o}[/tex] - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

[tex]n[/tex] - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that [tex]n(15\,min) = 80\,p[/tex] and [tex]n(45\,min) = 170\,p[/tex], then the following system of linear equations is formed:

[tex]15\cdot m + n_{o} = 80[/tex] (2)

[tex]45\cdot m + n_{o} = 170[/tex] (3)

The solution of the system of equations is:

[tex]m = 3[/tex] and [tex]n_{o} = 35[/tex]

The slope of the function is 3.

c) By (1) and using results from a) we conclude that the equation function is:

[tex]n(t) = 3\cdot t + 35[/tex] (4)

d) The y-intercept of the function is 35.

Step-by-step explanation:

Answer:

  The first question is A.

  The second question is C.

   The thid question is B., I think i'm not quit sure sorry

Answer:

option 1

Step-by-step explanation:

It's given in the question that

a (first term of an A.P.) = 14

d (common difference between terms of A.P.) = -3

So,

2nd term will be = a + d = 14 + (-3) = 11

3rd term = a + 2d = 14 + 2×(-3) = 8

4th term = a + 3d = 14 + 3×(-3) = 5

All these terms are matching with option 1. So, option 1 is the correct option
