the mean of 16,18,x,12 and 15 calculate the value of x
Answers
Answer:
29
Step-by-step explanation:
Mean = sum of datas/Sample size
Given the data 16,18,x,12 and 15
Sum = 16+18+x+12
Sum = 46+x
Mean = 15
Sample size = 5
Substitute
15 = 46+x/5
15 * 5 = 46+x
75 = 46 + x
x = 75-46
x = 29
Hence the value of x is 29

Help pls show work if needed!
Answers
Answer:
d = 50h
Step-by-step explanation:
We are using the linear property y = mx.
We know that distance = rate × time, so if we subsitute this, we get that the distance is d, the rate is 50 mph, and the time is h.
Therefore, we can form the equation d = 50h.
A market research analyst claims that 32% of the people who visit the mall actually make a purchase. You think that less than 32% buy something and decide to test the claim. You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase. The value of the test statistic is about:
A. 1.74
B. 1.60
C. 1.48
D. -1.60
E. -1.48
Answers
Answer:
E. -1.48
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A market research analyst claims that 32% of the people who visit the mall actually make a purchase.
This means that:
[tex]\mu = 0.32[/tex]
[tex]\sigma = \sqrt{0.32*0.68} = 0.4665[/tex]
You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase.
This means that [tex]n = 82, X = \frac{20}{82} = 0.2439[/tex]
The value of the test statistic is about:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.2439 - 0.32}{\frac{0.4665}{\sqrt{82}}}[/tex]
[tex]t = -1.48[/tex]
So the correct answer is given by option E.

Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Let x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiply both sides by 100.
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Divide both sides by 50.
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
The amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Therefore, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

The total area of three walls, each 8' feet high; 14, long, and other is 10' long?
Answers
Answer:
304 feet²
Step-by-step explanation:
Given three walls :
First wall : 8 feets high ; 14 inches long
Second wall : 8 feets high ; 14 inches long
Third wall : 8 feets high ; 10 feets long
Area = Length * height
Area = (8 * 14) = 112 ft²
Area = (8 * 14) = 112 ft²
Area = (8 * 10) = 80 ft²
Total area :
(112 + 112 + 80) ft²
= 304 feet²
THE amusement park won't allow kids to ride roller-coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inch every month. How many months will it be until Michael can read a roller coaster? Please show me the individual steps?
Answers
Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.
Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.
Answer:
48-42=6, which is how much Michael needs to grow.
1/2x=6, where x is the number of months
x = 12 months.
1 year = 12 months so the answer is one year.

Answer: The model is 69.420 feet tall.
Step-by-step explanation: I asked my teacher.
Answer:
5.5 cm

If you take 11 and divide it by 2 you would get 5.5cm. This is the answer because If 1cm is 2 ft you divide it by the actual height and you end up with how tall the model would be.

A store has clearance items that have been marked down by 35%. They are having a sale, advertising an additional 45% off clearance items. What percent of the original price do you end up paying?
Answers
Let’s pretend something at the store is $100. (It will save some math later)
100 - 35% leaves 65% (0.65 as a decimal)
100 x 0.65 = 65
That’s the price after the first discount. If we take 45% off of the sale price, we’ll be left with 55%, 0.55
65 x 0.55 = $35.75
Now normally you’d compare 35.75(sale price)/ 100(original price) to % off (x)/100, but doe this example, it’s unnecessary.
35.75/100 = x%/100
