Harold collected data on the daily high temperature in two cities over a period of one week.
He analyzed the data and found the measures below. Which statement is true, based on
these measures?
City Median Temperature Range from Median
Carlton
75°F
5 degrees
Borden
88°F
5 degrees
The daily low temperatures for the two cities were 70°F and 83°F.
Borden had at least one daily high temperature of 98°F.
The temperature in Carlton was always cooler than in Borden.
The difference between the daily high temperature for the two cities was 13 degrees.

Answers

The following statement is true with the given values of median and range.

The temperature in Carlton was always cooler than in Borden.

Median and range

The median is the middle number in a sorted ascending or descending list of numbers. The range is the difference between any two numbers.

How to find the median and the range?

Check the trueness of each statement with the given table.

First statement-The daily low temperatures for the two cities were[tex]70^{0}F[/tex] and [tex]83^{0}F[/tex].

Lowest temperature over a week [tex]=[/tex] Median - Range

Thus, for Carlton, it is [tex](75-5)=70^{0}F[/tex] and for Borden it is [tex](88-5)=83^{0}F[/tex]

So, this statement is not true.

Second statement-Borden of at least one daily high temperature of [tex]98^{0}F[/tex]

At least one daily high-temperature [tex]=[/tex] Median + Range

For Borden, it is [tex](88+5)=93^{0}F[/tex]

So, 2nd statement is not true.

Third statement-Temperature in Carlton was always cooler than in Borden.

For Carlton, at least one daily highest temperature (75+5)=[tex]80^{0}F[/tex]

For Borden, at least one daily lowest temperature [tex](88-5)=83^{0}F[/tex]

Borden's lowest temperature [tex]83^{0}F[/tex] was even more than Carlton's highest temperature [tex]80^{0}F[/tex].

So, the 3rd statement is true.

Fourth statement-The difference between the daily high temperature for the two cities was [tex]13^{0}F[/tex].

If the high temperature for Carlton for one day is [tex]80^{0}F[/tex] and for Borden [tex]83^{0}F[/tex], which is within the given range, then the difference is only [tex]3^{0}F[/tex].

So, the 4th statement is also not true.

Hence, the temperature of Carlton was always cooler than in Borden is the true statement.

Math homework, don't get it please explan!

Answers

Answer:

-1/2

Step-by-step explanation:

The slope of the line is y=mx+b. when searching for the slope of a line you take where the line crosses EXACTLY on two points, for this grid it would be (0,3) and (2,2) based off this you see that you Rise 1 and Run 2. rise and run is how you find the formula for slope, since the line is going from the left side of the graph to the right (in a downward motion) the overall direction of the line is negative. now you plug in the answer to the formula given, y=-1/2x+3, the +3 or b in the formula is where the line intersects the y axis. this can be negative or positive. the slope can also be taken from the formula, -1/2for more explanation or questions ask please!

Step-by-step explanation:

____ | <40 | 》40 | Total

< 30 | W | X | 1.0

》30 | Y | Z | 1.0

Total | 0.43 | 0.57 | 1.0

Since W, X, Y and Z are conditions frequency, they can't be negative

Therefore,

W and Y are both less than 0.43

X and Z are both less than 0.57

The only option less than 0.43 is 0.19 (for Y)

a line passes through the point (-9, 1) and had a slope of -2/3. Write an equation in point-slope form for this line

Answers

Answer:

y-1=-2/3(x+9)

Step-by-step explanation:

y-1=-2/3(x-(-9))

y-1=-2/3(x+9)

Hello!

To write an equation for this line, you must follow these steps:

1. M= Slope (-2/3)
2. X1= -9
3. Y1= 1
4. First, take the equation y - y1 = m(x - x1)
5. Plug the values into the equation
6. Y - 1 = -2/3(x - (-9))
7. Change the sign
8. Y - 1 = -2/3(x +9)
9. Distribute the -2/3
10. Y - 1 = -2/3x - 6
11. Add 1 to both sides
12. Y = -2/3x - 5

This gives you a final answer of y = -2/3x -5 (note that this equation is in slope intercept form)

Triangle ABC is a right triangle. The legs of the triangle are AB = 6 cm and BC = 12 cm. Find the measure of angle A.

Answers

Answer:

63.4°

Step-by-step explanation:

Given that AB and BC are the legs of the right triangle, then opposite to angle A is side BC and adjacent to angle A is side AB.

By definition, the tangent of angle A is:

tan(∠A) = opposite leg / adjacent leg

tan(∠A) = BC/AB

tan(∠A) = 12/6

∠A = arctan(2)

∠A = 63.4°

WILL MARK THE BRAINLEIST Find the surface of the rectangle prism ,show all of your work

Answers

The answer is 108 as your surface area.

Work:
To find surface area, you find the area of each side and add it all together. For the bottom and the top sides, it’s 6 x 3 which equals to 18. 18 + 18 = 36. Then, 3 x 4 = 12. 12 + 12 = 24. 6 x 4 = 24. 24 + 24 = 48. Then, you add it all together which equals to 108. If what I did doesn’t makes sense, I’ll explain it more detailed here.

So, I found the area of the bottom side and multiplied it by 2 to represent the top and bottom sides. Then, I did the same thing for the other sides if that makes sense. I’m really sorry if I’m not explaining it well. I’m better at doing the work in my head and not on paper or explaining it to other people.
