A rectangular prism has a length of 4m, a height of 11m, and a width of 17m. What is its volume, in cubic m?
Answer:
748m³
Step-by-step explanation:
Hello!
The volume of a rectangular prism is determined by the formula [tex]l * w * h[/tex]. To find the volume is to find how much space the object takes up in 3D. The formula is used to find the area of the base ( [tex]l * w\\[/tex] ), or the space taken on a 2D plane and multiplied by the height to give it 3 Dimensions.
Breakdown of [tex]l * w * h[/tex]:
[tex]l[/tex] is length[tex]w[/tex] is width[tex]h[/tex] is heightFind the Volume:
Use the formula and plug in values into the formula.
V = l * w * hV = 4 * 17 * 11748Th units of length are m, and volume is the units cubed, so the units are m³.
The volume is 748m³
Answer:
748
Step-by-step explanation: V= W*H*L
17*11*4= 748m^3
Ramon received a $100 bill as a graduation gift. He bought a game online for $24. 95. Then he bought a backpack for $39. 75 at a variety store. How much money did he have left after making the purchases?
Answer:
$35.30
Step-by-step explanation:
24.95+39.75 because this is the money he has spent.
This, in total, will be 64.7
Lastly, the problem states that Ramon has $100 in total, so you subtract.
$100-64.7=35.3
He has $35 and 30 cents left.

The median number of visitors to a local zoo each day is 893. A sample median of 1,005 visitors would be most likely to occur for which sample size? n = 20 n=75 n = 300 n 500 n=1,000
A sample median of 1,005 visitors would be most likely to occur for the sample size given by: Option A: 20
What does median behave like for large sample?As the value of n (the sample size) grows larger, the sampling distribution tends to being normal. For an approximate normal distribution, its mean, median, and mode all are approx coincident. And as the sample size increases, the sample mean tends to being the population mean as per the weak law of large numbers. For n > 30, we can approximate it using normal distribution usually.
We're given that:
Population median (the real median of the number of visitors to the zoo) = 893We want to choose value of n from 20, 75,, 300, 500, 1000 for which the sample median would be 1005.So, as we know, as the sample size increases, the sample mean and sample median and sample mode, all will tend to the population mean, median and mode (assuming population is large enough that they're all same).
Thus, the smaller the sample size, the more likely it is for holding 1005 as sample median instead of approx 893.
So, size 20 is most likely to have that median as it is the smallest sample size given.
Thus, a sample median of 1,005 visitors would be most likely to occur for the sample size given by: Option A: 20

In the same coffee shop, another group of friends
ordered 4 muffins and 3 cups of coffee for $32.85.
Algebraically determine the price of one muffin and
one cup of coffee.
Answer:
1 muffin is 5.25 and 1 cup of coffee is 3.95
Step-by-step explanation:
32.85 - 22.35 is 10.5. 10.5 divided by 2 is 5.25 that is the cost of 1 muffin. 22.35 - 10.5 is 11.85. 11.85 divided by 3 is 3.95.

reflect (7,4) across the x-axis then reflect the result across the y-axis what are the coordinates of the final point
The coordinates of the final point after the two reflections is (-7, -4)
How to reflect a point across an axis?
For a point (x, y), a reflection across the x-axis gives the point (x, -y), while for a point (x, y) a reflection across the y-axis gives (-x, y).
In this case, we have the point (7, 4), first we reflect across the x-axis, so we get the point (-7, 4).
Now we reflect across the y-axis, so the sign of the y-component changes, and we get (-7, -4)
So the coordinates of the final point after the two reflections is (-7, -4).

Then write an inverse variation function that can be used to calculate the cost per person, c, of p persons sharing the rental fee.
Step-by-step explanation:
c = cost per person
p = number of people
The cost per person is 1500/p, where
is the number of people. A larger p creates a smaller value of c since they are INVERSELY RELATED.

A car company claimed that it improved the gas mileage of a particular model of car between 2011 and 2012. A consumer advocacy group obtains a random sample of 16 cars from 2011 and finds the average number of miles driven on exactly 25 gallons of gas in laboratory conditions is 574. 4 miles, with a standard deviation of 43. 1 miles. The consumer advocacy group also obtains a random sample of 24 cars from 2012 and finds the average number of miles driven on exactly 25 gallons of gas in laboratory
conditions is 604. 6 miles, with a standard deviation of 27. 8 miles. The 99% confidence interval for the difference in mean miles driven on 25 gallons of gas (2012 model – 2011 model) is (–3. 95, 64. 35).
Does this confidence interval support the company’s assertion that their gas mileage has increased?
a)Yes, we are 99% confident that the true mean difference in miles driven per 25 gallons is 30. 2 miles.
b)Yes, the fact that most of the values in the confidence interval are positive means that the true mean number of miles driven on 25 gallons is higher in 2012.
c)Yes, the 2012 sample mean of 604. 4 miles per 25 gallons is 30. 2 more miles than the 2011 sample mean of 574. 4, which is an increase of 1. 208 miles per gallon.
d)No, the confidence interval contains 0, so we are 99% confident that the true mean increase in number of miles driven on 25 gallons is 0.
e)No, the confidence interval contains 0, so 0 is a plausible value for the true mean increase in number of miles driven on 25 gallons. An increase of 0 would indicate the gas mileage has not increased
Using the interpretation of the confidence interval, it is found that the correct option is:
e) No, the confidence interval contains 0, so 0 is a plausible value for the true mean increase in number of miles driven on 25 gallons. An increase of 0 would indicate the gas mileage has not increased.
What is the interpretation of a x% confidence interval?It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
In this question, the 99% confidence interval for the increase is of (-3.95, 64.35). It contains 0 and negative values, hence those are plausible values, and this is not enough evidence that the mean has increased, hence option e is correct.
