2) Find the median for his data set of days that had a temperature above 40 degrees C.
3) Find the mode for his data set of days that had a temperature above 40 degrees C.
4) If, instead, there are 5 more days per month that had a temperature above 40 degrees C, what will be the mean for the data?
5) If, instead, there are 2 more days per month that had a temperature above 40 degrees C, what will be the mode for the data?
6) If the number of days per month that had a temperature above 40 degrees C, doubles each month in that year, what will be the median for the data?

Triangle JKL was dilated with the origin as the center of dilation to create triangle J'K'L'. The triangle was dilated using a scale factor of 1/2. The coordinates of the vertices of triangle JKL are given. You can use the scale factor to find the coordinates of the dilated image. Enter the coordinates of the vertices of triangle J'K'L' below.
(Decimal values may be used.)
Answers
Answer:
J' (-2, 2.5), K' (1, 2.5) L' (1, -2.75)
Step-by-step explanation:
With a scale factor of 1/2=.5 you can simply multiply all coordinates by .5 (or divide by 2)
J (-4,5) x 1/2= (-2, 2.5)
K (2,5) x . 5 = (1, 2.5)
L (2, -5.5) /2= (1, 2.75)
Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Jorge invested a total of $5000. He invested some of his money at 4% and the rest at 7%. If the total return at the end of the year was $320, how much was invested at each rate?
Answers
Step-by-step explanation:
Let's solve this problem using a system of equations.
Let's assume that Jorge invested x dollars at 4% interest and (5000 - x) dollars at 7% interest.
The interest earned from the 4% investment can be calculated as (4/100) * x.
The interest earned from the 7% investment can be calculated as (7/100) * (5000 - x).
According to the problem, the total return at the end of the year was $320. Therefore, we can set up the following equation:
(4/100) * x + (7/100) * (5000 - x) = 320
Simplifying and solving for x:
(4/100) * x + (7/100) * 5000 - (7/100) * x = 320
0.04x + 0.07(5000 - x) = 320
0.04x + 350 - 0.07x = 320
-0.03x = -30
x = -30 / -0.03
x = 1000
Jorge invested $1000 at 4% interest and the remaining amount, $5000 - $1000 = $4000, at 7% interest.
Therefore, Jorge invested $1000 at 4% and $4000 at 7%.

Answers
3.50 rounds up to 4.00 4.49 rounds down to 4.00
The actual price per gallon of milk should be between $4.01 to $4.49.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, The price of a gallon of milk, rounded to the nearest dollar, is $4.00.
∴ The actual price per gallon of milk should be between $4.01 to $4.49

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.
Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

I need help on a b and function 2
I dont get it
Answers
Answer:
For A: The first function has a greater ROC
For B: The first function has a negative slope
Step-by-step explanation:
Explication for A:
We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1
after substituting: (-3-(-6))/(0-(-1))
simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first
Explanation for B:
The first function described is f(x)=20-3.5x
This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.
The second function described is c(m)=5x+10
This is because the equation represents the total cost of renting a calculator, so both terms are positive.
