Sure hope this helps you and pls mark me brainiestfor the quadratic function f(x)=5x^2-2x+3, find f(x+2), f(x+2)-f(x), and f(x+h)
Answer:
f(x + 2) = 5x² + 18x + 19
f(x + 2) - f(x) = 20x + 16
f(x + h) = 5x² + 10hx + 5h² - 2x - 2h + 3
Step-by-step explanation:
1. f(x + 2)
[tex]f(x)=5x^2-2x+3\\f(x+2)=5(x+2)^2-2(x+2)+3\\f(x+2)=5(x+2)(x+2)-2(x+2)+3\\f(x+2)=5(x^2+4x+4)-2(x+2)+3\\f(x+2)=5x^2+20x+20-2(x+2)+3\\f(x+2)=5x^2+20x+20-2x-4+3\\f(x+2)=5x^2+18x+20-4+3\\f(x+2)=5x^2+18x+19[/tex]
2. f(x + 2) - f(x)
[tex]f(x+2)-f(x)\\(5x^2+18x+19)-(5x^2-2x+3)\\5x^2-5x^2+18x-(-2x)+19-3\\0x^2+18x+2x+16\\20x+16[/tex]
3. f(x + h)
[tex]f(x)=5x^2-2x+3\\f(x+h)=5(x+h)^2-2(x+h)+3\\f(x+h)=5(x+h)(x+h)-2(x+h)+3\\f(x+h)=5(x^2+2hx+h^2)-2(x+h)+3\\f(x+h)=5x^2+10hx+5h^2-2(x+h)+3\\f(x+h)=5x^2+10hx+5h^2-2x-2h+3[/tex]

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

The cost to rent a condominium at the beach is $1,500 per week. If two people share the cost, they each have to pay $750. Explain why the relationship between the cost per person varies inversely with the number of persons sharing the cost. 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.
I believe the inverse variation function is
c = 1500 × 1/p

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

where something like [tex]5 \big| 0[/tex] represents the number 50.
The most frequent leaf is "0" in the very bottom row. It shows up four times, which is the most of any of the other leaf.
This leaf ties to the stem of 9.
stem = 9 & leaf = 0 leads to the data value 90.
Therefore, the mode is 90

Answer:
The answer is, y = 1060.64
Step-by-step explanation:
First, you want to multiply both sides by 38, which gives you
38y = 157y -126216.
Then you want to rearrange:
119y = 126216
then you want to divide by 119, which gives you y=126216/119, which is 1060.64
