Step-by-step explanation:
10% of 35,000 is the same as .10 × 35,000, or 3,500.
The mean, median, and mode of the 5 number 5, 7, 8, a, b are equal. (the list have a single mode.) find all the possibilities of a+b
The mean, median, and mode of the 5 number 5, 7, 8, a, b. are equal so
the possibilities of a+b is 20.
what is mean?The" mean" is the" average" you are used to, where you add up all the figures and also divide by the number of figures.
what is median?The" median" is the" middle" value in the list of figures. To know the median, your figures have to be listed in numerical order from lowest to largest, so you may have to rewrite your list before you can find the median.
what is mode?The" mode" is the value that occurs utmost often. However, also there's no mode for the list, If no number in the list is repeated.
According to the given Information:Given numbers are: 5, 7, 8, a, b
Total number =5
Then,
The mean = (5+7+8+a+b) / 5
Mean=(20+a+b) / 5 ------------------ (1)
Median=middle value in the list of figures
Median=8 ------------------(2)
According to the question ,mean and median are equal
Compare equation (1) and (2),
we get
= (20+a+b) / 5=8 20+a+b
=40a+b=20
there is no repetition of any number, so no mode is there
hence, all the possibilities of a+b is 20.

Translating 4 to the right means that you should add 4 to the x value of your coordinate point.
Question 18: C. (3,-5)
This is because reflecting over the x-axis would mean to move down the same amount of units above the x-axis the original point is (the original point is five units above the x-axis so you just move down five units). Look at the attached picture for more help.
Question 19: A. C’ (0,-2)
We can see that the triangle has been translated 1 unit to the right and 2 units up. This would mean you add 1 to the x-value of the coordinate and add 2 to the y-value of the coordinate. I can’t see point C clearly, but I’m guessing that it’s at (-1,-4). This would give point C’ as (0,-2)

For given question,
We have been given a function g(x, y) = 9x² + 6y² subject to the constraint −1≤x≤1 and −1≤y≤7
We need to find the absolute maximum and minimum values of the function.
First we find the partial derivative of function g(x, y) with respect to x.
⇒ [tex]g_x=18x[/tex]
Now, we find the partial derivative of function g(x, y) with respect to x.
⇒ [tex]g_y=12y[/tex]
To find the critical point:
consider [tex]g_x=0[/tex] and [tex]g_y=0[/tex]
⇒ 18x = 0 and 12y = 0
⇒ x = 0 and y = 0
This means, the critical point of function is (0, 0)

Uan zhang bought a 10-year bond that pays 8. 25 percent semiannually for $911. 10. what is the yield to maturity on this bond? (roundyour percentage answer to two decimal places. )
The yield to maturity on this bond according to the trial-and-error approach is 9.66 percent.
According to the statement
we have given that the Uan zhang bought a 10-year bond that pays 8. 25 percent interest per 6 months.
And we have to find that the yield to maturity on this bond.
So, For this purpose,
The amount given is $911. 10.
Years to maturity = n = 10
Coupon rate = C = 8.25%
Semiannual coupon = $1,000 × (0.0825/2) = $41.25
Yield to maturity = i
Present value of bond = PB = $911.10
Use the trial-and-error approach to solve for YTM. Since the bond is selling at a discount, we know that the yield to maturity is higher than the coupon rate.
Try YTM = 9.4%:
= $522.90 + 391.54 ≅ $914.43
The YTM is approximately 9.66 percent. Using a financial calculator provided an exact YTM of 9.656 percent (2 × 4.828%).
So, The yield to maturity on this bond according to the trial-and-error approach is 9.66 percent.

Explain what is meant by intercepts with the axes give examples of y and x intercepts
Intercepts with the axes are where your line touches the x or y axis. An example is a straight line, say, y=4x+2. In this case, the y-intercept is 2 because the line touches the y-axis at (0, 2). With y=mx+b format, the y-intercept is b. To find the x-intercept of an equation in y=mx+b format, set y to zero and solve for x. In a parabola, the x-intercepts would be the roots. An example of this is x^2 - 5x + 4 = 0. The roots here are (4,0) and (1,0). Hopefully this helped.

The mark on the tape measure that is closest to 3.16228 is 3.1875
How to determine the closest measure?The measurement is given as:
Length = 3.16228
The tape measure is marked in sixteenths of an inch i.e 1/16 or 0.0625
So, we have the following range:
0.0625, 0.125, 0.1875, 0.25,.....
Rewrite the range as follows:
3.0625, 3.125, 3.1875, 3.25,.....
The length 3.1622 is between 3.125 and 3.1875.
The difference between the measurement and the range is
3.16228 - 3.125 = 0.03728
3.1875 - 3.16228 = 0.02522

Given,
The probability of winning on an arcade game, p = 0.659
Number of times you play arcade game, n = 30
By assuming this as a normal distribution, we get
Mean=μ=30×0.659 =19.77
Standard deviation, σ = [tex]\sqrt{np(1-p)}[/tex]
= [tex]\sqrt{30(0.659)(1-0.659)}[/tex]
≈ 2.60
Let X be a binomial variable
Then, the z score for x = 21 will be:
z = (x - μ) / σ = [tex]\frac{21-19.77}{2.60}[/tex]
≈ 0.47
Now, the probability of winning exactly 21 times
P (x ≥ z) = P (21 ≥ 0.47) = 0.32
Hence the probability of winning exactly 21 times is 0.32

How long is the arc intersected by a central angle of startfraction pi over 2 endfraction radians in a circle with a radius of 4.5 cm? round your answer to the nearest tenth. use 3.14 for pi.
7.1 cm long is the arc intersected by a central angle .
What is length of an arc?
The arc length of a circle can be calculated with the radius and central angle using the arc length formula. Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ is in degree.Given,
Central angle = π / 2
radius = 4.5 cm
we apply formula of length of arc.
length of the arc = angle × radius
= (π/2) × (4.5 cm)
Now put value of π = 3.14
length of the arc = (3.14 / 2) × (4.5) cm
= 7.065 cm ≈ 7.1 cm
Therefore, 7.1 cm long is the arc intersected by a central angle .

What is the height of a rectangular prism with a volume of 80 cubic feet and a base area of 25 square feet?
Volume=80cubic feet
Length×Width×Height =80cubic feet
Base area×Height =80cubic feet
25square feet×Height =80cubic feet
Height =80÷25
=3.2feet
The height of the rectangular prism is 3.2 feet.
To determine the height of a rectangular prism with a volume of 80 cubic feet and a base area of 25 square feet,
The volume of a rectangular prism, that is V = lwh, where l is the length, w is the width, and h is the height of the prism.
Given:
Volume (V) = 80 cubic feet
Base area (A) = 25 square feet
We know that the base area is equal to the product of the length and width:
A = lw.
Calculate the length (l) and width (w) from the given base area:
We know that A = lw, and A = 25 square feet.
If we assume the length to be greater than the width, we can express the base area as lw = 25.
We need to find two factors of 25 that have a difference as small as possible. The factors of 25 are 1, 5, and 25.
We can choose l = 5 feet and w = 5 feet.
V = lwh.
80 = 5 * 5 * h
Divide both sides of the equation by 25:
80/25 = h.
h = 16/5 = 3.2 feet.
Therefore, the height of the rectangular prism is 3.2 feet.

4. Emily’s house has a chimney. What is the volume of her chimney? 4 in 9 in 12 in 3 in 4 in 6 in
Using the volume for rectangular prisms, the volume of the chimney is: 216 in.³.
What is the Volume of a Rectangular Prism?The volume of a rectangular prism = (length)(width)(height).
How to Find the Volume of Composite Shapes?The Chimney in Emily's house is a composite solid consisting of two rectangular prism. To find the volume, we have to decompose the figure into two rectangular prisms. Then solve for the volume of each before finding the total volume.
Volume of the bigger rectangular prism = (length)(width)(height) = (4)(4)(12)
Volume of the bigger rectangular prism = 192 in.³
Volume of the smaller rectangular prism = (length)(width)(height) = (4)(2)(3)
Volume of the smaller rectangular prism = 24 in.³
The volume of the chimney = volume of the two rectangular prism
The volume of the chimney = 192 + 24
The volume of the chimney = 216 in.³
