Which graph is the solution to the inequality?

y - 13 > -85
13 < -85 + y
y + 13 < -85

Answer:

  {6-√21, 6+√21}

Step-by-step explanation:

It usually works well to put the x-terms on one side of the equal sign. Then add the square of half the x-term coefficient.

  x^2 -12x = -15 . . . . . . subtract 12x

The x-term coefficient is -12, so the square of half that is (-12/2)^2 = 36. Adding 36, we have ...

  x^2 -12x +36 = -15 +36

  (x -6)^2 = 21

  x -6 = ±√21 . . . . . take the square root

  x = 6 ±√21 . . . . . add 6

The solution set is ...

  {6-√21, 6+√21}

Answer:

[tex] p(O)=\frac{8}{18}=\frac{4}{9}[/tex]

And since we want the complement of choosing an orange juice box the answer would be:

[tex] P(O') =1 - P(O) = 1-\frac{4}{9}= \frac{5}{9}[/tex]

And the nest answer for this case is:

5/9

Step-by-step explanation:

For this case we know that we have 4 apple juice boxes, 8 orange juice boxes, and 6 fruit punch juice boxes, so then the size of the sample space is:

[tex] 8+4+6= 18[/tex]

Then we can find the probability of selecting an orange juice box with the definition of Laplace given by:

[tex] p =\frac{possible}{total}[/tex]

And for this case the possible cases are 4 and the total 18 so then the probability is given by:

[tex] p(O)=\frac{8}{18}=\frac{4}{9}[/tex]

And since we want the complement of choosing an orange juice box the answer would be:

[tex] P(O') =1 - P(O) = 1-\frac{4}{9}= \frac{5}{9}[/tex]

Answer: The paper going to cost $16.31 for those reports.

Step-by-step explanation:

Given, the length of a long year-end status report for work = 144

If we ned to print  16 copies for a meeting next week, the total number of pages required = 16 *144

= 2304

Since, the paper is sold in reams of 500 pages = $3.54

Then, cost of one page = (Cost of a ream of 500 pages) ÷ 500

= $3.54 ÷ 500

=  $ 0.00708

Cost of  total number of pages required  = 2304x (cost of one page)

= 2304 x ($ 0.00708)

= $ 16.31232 ≈ $16.31

Hence, the paper going to cost $16.31 for those reports.

Answer: 22,084,920 different clubs

Step-by-step explanation:

The club must have 6 juniors and 8 seniors

We have a total of 13 juniors and 16 seniors.

Now, we know that the possible combinations of N objects into a group of K is equal to:

[tex]C = \frac{N!}{(N-K)!*K!}[/tex]

For the juniors we have N = 13 and K = 6

[tex]Cj = \frac{13!}{7!*6!} = \frac{13*12*11*10*9*8}{6*5*4*3*2*1} = 1716[/tex]

For the seniors we have N = 16 and K = 8

[tex]Cs = \frac{16!}{8!8!} = \frac{16*15*14*13*12*11*10*9}{8*7*6*5*4*3*2*1} = 12870[/tex]

Now, as the group consist on both combinations togheter, the number of different clubs that can be formed are:

C = Cj*Cs = 1,716*12,870 = 22,084,920

In order to wipe out the whole job, it takes

(9 persons) x (8 hours/day) x (25 days)  =  1,800 person-hours .

12 workers working for 15 days will accomplish

(12 persons) x (H hours/day) x (15 days)  =  180H person-hours  of work.

180H person-hours  =  1,800 person-hours

H = 10

The 12-person team must work 10 hours/day to make this scheme all work out.  

What'll really happen:  

-- In order to keep tabs on the project and make sure it gets done on the accelerated schedule, the managers in Chicago in suits will assign the supervisor to complete the project in 14 days instead of 15, and they'll require him to send them a status report twice each day.

-- After completing and emailing the Noon status report each day, the supervisor will put on his hard-hat and PPE, and head out to work alongside the 12 sweating workers, who will all begin to sag when they pass 9 hours each day.

-- Day #12 will be solid torrential rain, and no progress will be possible.  The men will want to get some rest, but Chicago will call a Zoom meeting to deliver a motivational pep-talk. Attendance will be mandatory.

-- Days #13 and #14 will stretch to 12 hours, but the project will finish in the allotted 14 days.

-- On Day #15, in Chicago, the customer will treat the managers to a fine dinner, drinks, and a Bulls game, in appreciation for completing the project in 15 days.  In the field, the supervisor and the 12 workers will get to sleep in for a whole hour later than usual, before they clean up the job site and begin the long drive home.

Answer:

We conclude that there is difference in the proportion of deaths between the 2 groups.

Step-by-step explanation:

We are given that among 2823 drivers not wearing seat belts, 31 died as a result of injuries, and among 7765 drivers wearing seat belts 16 were killed.

Let [tex]p_1[/tex] = proportion of deaths when drivers were not wearing seat belts.

[tex]p_2[/tex] = proportion of deaths when drivers were wearing seat belts.

So, Null Hypothesis, [tex]H_0[/tex] : [tex]p_1=p_2[/tex]      {means that there is no difference in the proportion of deaths between the 2 groups}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]p_1\neq p_2[/tex]     {means that there is difference in the proportion of deaths between the 2 groups}

The test statistics that would be used here Two-sample z test for proportions;

                          T.S. =  [tex]\frac{(\hat p_1-\hat p_2)-(p_1-p_2)}{\sqrt{\frac{\hat p_1(1-\hat p_1)}{n_1}+\frac{\hat p_2(1-\hat p_2)}{n_2} } }[/tex]  ~ N(0,1)

where, [tex]\hat p_1[/tex] = sample proportion of deaths when drivers were not wearing seat belts = [tex]\frac{31}{2823}[/tex] = 0.011

[tex]\hat p_2[/tex] = sample proportion of deaths when drivers were wearing seat belts = [tex]\frac{16}{7765}[/tex] = 0.002

[tex]n_1[/tex] = sample of drivers not wearing seat belts = 2823

[tex]n_2[/tex] = sample of drivers wearing seat belts = 7765

So, the test statistics  =  [tex]\frac{(0.011-0.002)-(0)}{\sqrt{\frac{0.011(1-0.011)}{2823}+\frac{0.002(1-0.002)}{7765} } }[/tex]

                                       =  4.438

The value of z test statistics is 4.438.

Now, at 5% significance level the z table gives critical values of -1.96 and 1.96 for two-tailed test.

Since our test statistic doesn't lie within the range of critical values of z, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore, we conclude that there is difference in the proportion of deaths between the 2 groups.

Also, Margin of error (E) =  [tex]1.96 \times \sqrt{\frac{\hat p_1(1-\hat p_1)}{n_1}+\frac{\hat p_2(1-\hat p_2)}{n_2} }[/tex]

                                        =  [tex]1.96 \times \sqrt{\frac{0.011(1-0.011)}{2823}+\frac{0.002(1-0.002)}{7765} }[/tex]

                                        =  0.00397

Answer: 3/4 of the original price.

Step-by-step explanation:

Ok, so Sam buys 4 boxes in Store A.

We know that in Store A you can get 4 boxes paying only for 3.

If P is the price of a Box, then he got 4 boxes and paid 3*P

then the amount that he paid for each box is equal to the total amount that he paid divided the number of boxes that he received.

this is: 3P/4 = (3/4)*P

Meaning that he paid 3/4 of the original price for each box.

Answer:

Null hypothesis: [tex] \mu \geq 60[/tex]

Alternative hypothesis: [tex] \mu <60[/tex]

Since the sample size is large enough we can assume that the distribution for the statistic is normal so then in order to find the critical value for this test taking in count the significance level given of 0.05 we need to look in the normal standard distribution a value who accumulates 0.05 of the area in the left and would be:

[tex] z_{crit}= -1.64[/tex]

Step-by-step explanation:

For this case we have the following data given:

[tex] \bar X = 53[/tex] represent the sample mean

[tex] s = 23[/tex] represent the sample deviation

[tex]n = 10000[/tex] represent the sample size.

We want to test for this case if the true mean is less than 60 so then the system of hypothesis are:

Null hypothesis: [tex] \mu \geq 60[/tex]

Alternative hypothesis: [tex] \mu <60[/tex]

Since the sample size is large enough we can assume that the distribution for the statistic is normal so then in order to find the critical value for this test taking in count the significance level given of 0.05 we need to look in the normal standard distribution a value who accumulates 0.05 of the area in the left and would be:
