Answer:
300,000
Step-by-step explanation:
Given the following question:
[tex]324145[/tex]
To round to the nearest hundred thousand of this number we must first find the hundred thousand place value and then determine if the number next to that place value is greater than five, if so, we can round the number up.
[tex]324145[/tex]
[tex]PV=3[/tex]
[tex]2 < 5[/tex]
[tex]=30000[/tex]
Rounded to the nearest hundred thousand "300,000" is your answer.

A toy store received a large shipment of toy race cars. The cars come in blue and red. Because the red cars are more popular, the toy store wanted the ratio of red cars to blue cars to be 3:2. If total number of cars received was 40, then how many of the cars were red?
Answer:
24 cars
Step-by-step explanation:
Given
[tex]Red:Blue = 3:2[/tex]
[tex]Cars = 40[/tex]
Required
Determine the number of red cars
Number of red cars is calculated using:
[tex]Red\ Cars = \frac{Red\ Ratio}{Total\ Ratio} * Cars[/tex]
[tex]Red\ Cars = \frac{3}{3 + 2} * 40[/tex]
[tex]Red\ Cars = \frac{3}{5} * 40[/tex]
[tex]Red\ Cars = \frac{3 * 40}{5}[/tex]
[tex]Red\ Cars = \frac{120}{5}[/tex]
[tex]Red\ Cars = 24[/tex]

A wedding tent is built in the shape of a right rectangular prism topped with a
rectangular pyramid. The dimensions of the prism are 21 ft by 27 ft by 8 ft,
and the height of the pyramid is 2 ft. Find the total volume of the tent. Round
your answer to the nearest tenth if necessary.
Based on the calculations, the total volume of this wedding tent is equal to 4,914 [tex]ft^3[/tex]
Given the following data:
Dimensions of prism (LWH) = 21 ft x 27 ft x 8 ft.Height of pyramid = 2 ft.How to calculate the total volume of the tent.First of all, we would determine the volume of the right rectangular prism by using this formula:
[tex]V=LWH\\\\V=21 \times 27 \times 8\\\\V=4536\;ft^3[/tex]
Also, we would determine the volume of the pyramid by using this formula:
[tex]V=\frac{1}{3} BH\\\\V=\frac{1}{3}\times (21\times 27)\times 2\\\\V=378\;ft^3[/tex]
For the total volume:
Total volume = [tex]4536+378[/tex]
Total volume = 4,914 [tex]ft^3[/tex]

A circle has the equation x² + y2 = 7
P is the point (-2,13) on the circle x² + y2 = 7
Work out the equation of the tangent to the circle at P.
Answer:
A tangent to a circle at point P with coordinates is a straight line that touches the circle at P. The tangent is perpendicular to the radius which joins the centre of the circle to the point P. As the tangent is a straight line, the equation of the tangent will be of the form y = m x + c .

Brett is performing a hypothesis test in which the population mean is 310 and the standard deviation is 20. His sample data has a mean of 295 and a sample size of 50. Which of the following correctly depicts the z-statistic for Brett’s data? –5. 30 –0. 11 4. 28 6. 27.
Z-score of given data comes to be -5.30.
It is given that
Population mean μ= 310
Standard deviation σ= 20
Mean of sample data X= 295
Sample size n= 50
What is z-score?A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
For a hypothesis test
Z-score = (X-μ)/(σ/√n)
Where, X = observed value
μ= mean
σ = standard deviation
n =sample size
Z-score of above data = (295-310)/(20/√50)
Z-score = -5.30
Therefore, Z-score of given data comes to be -5.30.

Hey there!
First of all, what is this "√" sign?
It means "square root"
Wow, numbers have square roots? Yes.
The square root of a number is the opposite of squaring a number.
Squaring a number simply means multiplying it times itself.
So taking the square root of a number is the opposite of squaring a number.
So, we have

In calculating the monthly payment for a loan with an 8.5% interest rate compounded monthly, what value should be used for i, the interest rate per period, as it appears in the following formula? p = p v times startfraction i over 1 minus (1 i) superscript negative n endfraction a. 8.5 b. 0.71 c. 0.085 d. 0.0071
The value of i, the interest rate per period(monthly here) that should be used in the considered formula is given by: Option B: 0.71
How to find the monthly payment?If we're given that:
[tex]P_v[/tex] = present value[tex]P[/tex] = monthly payment to be paidi = interest rate per monthn = number of periods.Then, we get:
[tex]P = P_v\left(\dfrac{i}{1-(1+i)^{-n}}\right)[/tex]
For this case, we're provided that:
i = interest rate per period
And we have:
Interest rate compounding monthly = 8.5%
The interest rates are usually given for annual basis. Since i represents the rate per period, which is monthly here, thus, we will convert the rate 8.5% from annually to monthly.
Since 1 year = 12 months,
so 8.5% per year compounding monthly = (8.5/12)% per month compounding monthly
Thus, i = interest per period = interest per month = 8.5/12≈ 0.71 (in percentage)
Thus, the value of i, the interest rate per period(monthly here) that should be used in the considered formula is given by: Option B: 0.71

A regional transportation authority is interested in estimating the mean number of minutes working adults in the region spend commuting to work on a typical day. A random sample of working adults will be selected from each of three strata: urban, suburban, and rural. Selected individuals will be asked the number of minutes they spend commuting to work on a typical day. Why is stratification used in this situation?
A. To remove bias when estimating the proportion of working adults living in urban, suburban, and rural areas.B. To remove bias when estimating mean commuting time.C. To reduce bias when estimating mean commuting time.D. To decrease the variability in estimates of the proportion of working adults living in urban, suburban, and rural areas.E. To decrease the variability in estimates of the mean commuting time.
Answer:
To reduce bias when estimating mean commuting time
Step-by-step explanation:
Given that the selection of adults is based on the three strata found in the region; urban, suburban, and rural areas where the population and proportion of adults commuting to work is progressively decreasing, using a uniform number or sample size will not increase sample error as there are more commuters in the urban areas than in the suburban or rural areas, likewise, there are more commuters in the suburban area than in the rural areas, and as such the proportion of those sampled in the urban areas should be more than those surveyed in the suburban while those surveyed in the suburban areas should be more than those surveyed in the rural areas to reduce bias when estimating the mean as there will be more general representation.
