ȳ = 9
Step-by-step explanation:
ȳ (yBar) is used to represent mean value of y
Mean, which is the average score of the population on a given variable
It is represented by = ( Σ Xi ) / N
There are two steps to calculate mean value
Add the numberssum of all numbers = 3 + 7 + 8 + 11 + 16
= 45
2. Divide by how number of ys (there are 5 numbers)
45 / 5 = 9
So ȳ = 9
a cone and a sphere have the same volume. the height of the cone is 96 units. what would be the values for the radius of the cone and the sphere?
Answers
The volume [tex]V_c[/tex] of a cone with base radius [tex]r_c[/tex] and height [tex]h_c[/tex] is
[tex]V_c = \dfrac{1}{3}\pi r_c^2 h_c[/tex]
Similarly, the volume [tex]V_s[/tex] of a sphere with radius [tex]r_s[/tex] is
[tex]V_s = \dfrac{4}{3}\pi r_s^3[/tex]
We know that [tex]V_c=V_s[/tex] and that [tex]h_c=96[/tex]
So, we can set up the following equation:
[tex]\dfrac{96}{3}\pi r_c^2=\dfrac{4}{3}\pi r_s^3[/tex]
We can simplify the common denominator 3, and pi appearing on both sides:
[tex]96r_c^2=4r_s^3[/tex]
We can divide both sides by 4:
[tex]24r_c^2=r_s^3[/tex]
Without further information, this is all we can say: the cubed radius of the sphere is the same as 24 times the squared radius of the cone.
The values for the radius of the cone and the sphere is 24 units.
It is given that a cone and a sphere have the same volume.
It is required to find the radius of the cone and sphere if the height of the cone is 96.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of the cone:
[tex]\rm V_c = \pi R^2\frac{H}{3}[/tex]
Where R is the radius of the cone and H is the height of the cone.
And the volume of the sphere:
[tex]\rm V_s = \frac{4}{3} \pi r^3[/tex]
Where r is the radius of the sphere.
[tex]\rm V_c = V_s[/tex] (From the question)
[tex]\rm \pi R^2\frac{H}{3}=\rm \frac{4}{3} \pi r^3[/tex]
[tex]\rm \pi R^2\frac{96}{3}=\rm \frac{4}{3} \pi r^3[/tex] ( H = 96 units)
[tex]\rm 32R^2=\rm \frac{4}{3} r^3[/tex]
[tex]\rm 24R^2= r^3[/tex]
We are assuming that R = r
[tex]\rm 24r^2= r^3[/tex]
r = 24 units and
R = 24 units.
Thus, the values for the radius of the cone and the sphere is 24 units.

The percentage of people from the West that are insured is:
Answers
Do 55,427 divided by 67,103 which is 0.825998838 then multiply that by 100 to get 82.5998838 then round up to the nearest tenth to get 83 percent
The percentage of people from the West that are insured is 83%.
Given that, the U.S. government collects information on Americans who do not have health insurance.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Number people insured from west region = 55,427
Total number of people from west region = 67,103
So, percentage = 55,427/67,103 × 100
= 0.8259 × 100
= 82.59
≈ 83%
Therefore, the percentage of people from the West that are insured is 83%.

The expression 12h + 30w Identifies the amount paid to an employee.Let h represent hours and let w represent the total amount of g-wagons sold. Since the question explains that an employee works 6 hours and sells 3 wagons, put h as h = 6 and w as w = 3. We would end up getting this equation. 12h + 30w = 12(6) + 30(3).Now all you need to do is solve it.left side = 72right side = 9072 + 90 = 162Write the fractions as mixed number.

The area of a triangle is 1,4440 cm^2. The base of the triangle is 5 times the height. What is the height of the triangle?
Answers
Answer:
h = 24 cm
Step-by-step explanation:
The formula for area of a triangle is
A = (1/2)bh where b is the base and h is the height.
We are told that the base is 5 times the height, this translates to
b = 5h, so we can rewrite our formula to
A = (1/2)(5h)(h) or
A = (1/2)5h²
We are given A = 1,440, so plug that in and solve for h...
1,440 = (1/2)5h²
2,880 = 5h² (multiply both sides by 2 to get rid of the fraction)
576 = h² (divide both sides by 5 to get the h value by itself)
24 = h (take the square root of both sides)

Rob deposits $1000 in a savings account at New York State bank that pays 4.4% interest,compounded monthly. How much is in his account at the end of one year? What is the APY for this account to the nearest hundredth of a percent ?
Answers
Answer:
$45
Step-by-step explanation:
I used a compound interest calculator
Rob will have $1044.89 in his account at the end of one year. The APY for this account is 4.47%.
Explanation:The subject of the question is related to calculating the final balance of a savings account that earns compound interest. In Rob's case, he deposits $1000 in a bank account that pays 4.4% interest compounded monthly. In order to calculate the balance at the end of the year, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.
To find Rob's account balance at the end of one year, we would substitute the values into the formula as follows: A = 1000(1 + 0.044/12)^(12*1) = $1044.89. This means Rob will have $1044.89 in his account at the end of one year. The APY (Annual Percentage Yield) for this account is closer to the nominal rate due to the effect of monthly compounding, which follows the formula APY = (1 + r/n)^(nt) - 1. Substituting the values gives us, APY = (1+ 0.044/12)^(12) - 1 = 0.044682, which is approximately 4.47 after converting to percentage and rounding to the nearest hundredth of a percent.

So, 3.75 is 3 parts as per this ratio
Divide this amount by 3 to get 1 part in the ratio
3.75 / 3 = 1.25
Now simply multiply all the other ratios by this value to find how much the others get:
1.25 x 7 = 8.75
1.25 x 2 = 2.5
Paula gets £8.75 and Henry gets £2.50
The amount altogether would be their individual amounts added together:
8.75 + 2.50 + 3.75 = 15

The mean of the temperatures in the chart is 24° with a standard deviation of 4°. Which temperature is within one standard deviation of the mean? 18° 19° 22° 30°
Answers
Answer:
22°
Step-by-step explanation:
If the mean is m and the standard deviation is s, then we can say that the temperatures that fall within 1 standard deviation of the mean will be:
m - s < temperatures < m + s
To we take the sum of mean and standard deviation: 24 + 4 = 28
and, the different of mean and standard deviation: 24 - 4 = 20
So, the temperature that is in between 20 and 28 is the temperature within 1 standard deviation of the mean.
