A shopping center includes a grocery store and a drug store. One​ afternoon, a total of 200 people visited the shopping​ center, and 121 shopped at the grocery​ store, 91 shopped at the drug​ store, and 33 shopped at both businesses. ​a) How many people shopped at the grocery store or the drug​ store? ​b) How many people shopped at neither the grocery store nor the drug​ store?

Answers

Answer 1

9514 1404 393

Answer:

  a) 179

  b) 21

Step-by-step explanation:

When making a Venn diagram for a problem like this, it often works well to fill in the "both" quantity first. Then that is subtracted from the number for grocery to find "grocery only", and from the number for drug store to find "drug store only." The sum of the numbers inside the circles (88+33+58) is the number who shopped at the grocery or drug store. The number who shopped at neither is the difference between this number and the total number of shoppers (200-179).

A company that manufactures electronic components wants to know the mean discharge time of one particular type of capacitor that it makes. In order to estimate this value, they randomly select 100 capacitors and measure how long they take to discharge. The mean of this sample was 7.25 seconds with a standard deviation of 0.15 seconds. Assuming that this distribution is normal, construct a 99% confidence interval to estimate the mean discharge time for all capacitors of this type. Is this question asking for a confidence interval or hypothesis test

Answers

Answer:

99% confidence interval to estimate the mean discharge time for all capacitors of this type

(7.2146, 7.2854)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 100

Given that the mean of sample x⁻ = 7.25 seconds

Given that the standard deviation of the sample (S)  = 0.15 seconds

Level of significance = 0.01

Degrees of freedom = n-1 =100-1 =99

t₀.₀₁ , ₉₉ = 2.3646

We have to find that the 99% of the confidence interval of the mean

Step(ii):-

99% confidence interval to estimate the mean discharge time for all capacitors

[tex](x^{-} - t_{0.01 , 99} \frac{S}{\sqrt{n} } , x^{-} + t_{0.01 , 99} \frac{S}{\sqrt{n} } )[/tex]

[tex](7.25 - 2.3646 \frac{0.15}{\sqrt{100} } , 7.25 + 2.3646 \frac{0.15}{\sqrt{100} } )[/tex]

(7.25 - 0.0354 , 7.25 + 0.0354)

(7.2146, 7.2854)  

Final answer:-

99% confidence interval to estimate the mean discharge time for all capacitors of this type

I have ¾ of an hour to finish 6 homework assignments. How much time can I spend on each assignment?

Answers

Answer:

 7.5 min for each assignment

Step-by-step explanation:

1 hour is 60 minutes, and there are four 15 minute intervals. So, if there are four intervals of 15 minutes that add up to 60, just take three of them and put them over four:

15 ⋅ 15⋅ 15/ 15⋅ 15 ⋅ 15 ⋅ 15= 45 /60

Or we could multiply one hour, or 60 minutes, by  3 /4 .

    60 ⋅ 3/ 4 = 60 /1 ⋅ 3 /4 = 60 ⋅ 3/ 4 ⋅ 1 = 180 /4 =45

Three fourths of an hour is 45 minutes.

to find  time for each assignment =45/6

          7.5 min

Two triangles have bases with lengths 5in and 8in.
a. Find the ratio of the areas of the triangles

b. If the area of the smaller triangle is 15in², what is the area of the larger triangle?

Show work ​

Answers

Answer:

i. The ratio of the areas of the two triangles is 5:8.

ii. The area of the larger triangle is 24 in².

Step-by-step explanation:

Let the area of the smaller triangle be represented by [tex]A_{1}[/tex], and that of the larger triangle by [tex]A_{2}[/tex].

Area of a triangle = [tex]\frac{1}{2}[/tex] x b x h

Where; b is its base and h the height.

Thus,

a. The ratio of the area of the two triangles is:

[tex]\frac{area of the smaller triangle}{area of the larger triangle}[/tex]

Area of smaller triangle = [tex]\frac{1}{2}[/tex] x b x h

                                       = [tex]\frac{1}{2}[/tex] x 5 x h

                                       = [tex]\frac{5}{2}[/tex]h

Area of the lager triangle = [tex]\frac{1}{2}[/tex] x b x h

                                           = [tex]\frac{1}{2}[/tex] x 8 x h

                                           = 4h

So that;

Ratio = [tex]\frac{\frac{5}{2}h }{4h}[/tex]

         = [tex]\frac{5}{8}[/tex]

The ratio of the areas of the two triangles is 5:8.

b. If the area of the smaller triangle is 15 in², then the area of the larger triangle can be determined as;

[tex]\frac{area of the smaller triangle}{area of the larger triangle}[/tex] = [tex]\frac{5}{8}[/tex]

[tex]\frac{15}{A_{2} }[/tex] = [tex]\frac{5}{8}[/tex]

5 [tex]A_{2}[/tex] = 15 x 8

       = 120

[tex]A_{2}[/tex] = [tex]\frac{120}{5}[/tex]

    = 24

The area of the larger triangle is 24 in².

My math students challenged me, their math teacher, to play a dice game with them. They will give me 10 cents for each odd sum I roll with two dice, but I have to give them 10 cents for each even sum they roll with the two dice. I do not think this game is fair. I think I am going to get cheated! I noticed that I cannot roll one of my odd numbers: 1!

Should I play this game with the students? Use your mathematical thinking to convince me whether or not this is a fair game.

Answers

Answer:

No

Step-by-step explanation:

You can if you want, but there is a total of 6 on the dice. And there are 3 odds. Each odd you role you gain 10 cents, but each time a student roles a even they also get 10 cents. So you will get paid and in a game of chance and gambling. You won't gain anything if ALL of the students are together and going against you. Its like 1 vs 25 and you would have to pay a lot of students at one time to play this game. So logically no, because you won't gain money. But also you could if you always get odds, but again. That's a 3/6 or 1/2 each time you role to get a odd number.

Hope that helped, or even made sense xD
