Graph answer Click and drag to make a rectangle. Click a rectangle to delete it.
To construct a frequency histogram based on the given temperature data, we will use the temperature ranges as the x-axis and the number of days as the y-axis.
The temperature ranges and their corresponding frequencies are as follows:
30-39: 2 days
40-49: 26 days
50-59: 28 days
60-69: 8 days
70-79: 2 days
To create the histogram, we will represent each temperature range as a bar and the height of each bar will correspond to the frequency of days.
Using an appropriate scale, we can label the x-axis with the temperature ranges (30-39, 40-49, 50-59, 60-69, 70-79) and the y-axis with the frequency values.
Now, we can draw rectangles (bars) on the graph, with the base of each rectangle corresponding to the temperature range and the height representing the frequency of days. The height of each bar will be determined by the corresponding frequency value.

What values of x
and y
satisfy the system of equations {8x+9y=−36 x+7y=1}
Enter your answer as an ordered pair, like this: (42, 53)
If your answer includes one or more fractions, use the / symbol to separate numerators and denominators. For example, if your answer is (4253,6475),
enter it like this: (42/53, 64/75)
If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."
The solution to the system of equations is (x, y) = (-261/47, 44/47) as an ordered pair.
To solve the given system of equations:
Equation 1: 8x + 9y = -36
Equation 2: x + 7y = 1
We can use the method of substitution or elimination to find the values of x and y. Let's use the method of substitution:
From Equation 2, we can solve for x:
x = 1 - 7y
Substituting this value of x into Equation 1:
8(1 - 7y) + 9y = -36
8 - 56y + 9y = -36
-47y = -44
y = 44/47
Substituting the value of y back into Equation 2 to find x:
x + 7(44/47) = 1
x + 308/47 = 1
x = 1 - 308/47
x = (47 - 308)/47
x = -261/47
Therefore, as an ordered pair, the solution to the system of equations is (x, y) = (-261/47, 44/47).

What motivates producers and consumers in the black market
The motivations for producers and consumers in the black market are largely driven by financial incentives and a desire to avoid legal consequences.
The black market refers to the illegal trade of goods and services that are not permitted by law, such as drugs, counterfeit items, and stolen goods. Producers and consumers in the black market are motivated by a variety of factors, including:
High profits, Producers in the black market can earn higher profits than they would in legal markets due to the lack of regulation and taxes.
Escaping legal consequences: Producers and consumers may participate in the black market to avoid legal consequences, such as fines or imprisonment, for engaging in illegal activities.
Limited availability, Some goods and services are only available on the black market due to legal restrictions or limited supply.
Low prices, Consumers in the black market can often purchase goods and services at lower prices than in legal markets due to the lack of taxes and regulations.
Desire for anonymity, The black market can provide anonymity for both producers and consumers, allowing them to engage in illegal activities without fear of detection or retribution.
However, participating in the black market also comes with significant risks, including the possibility of arrest, fines, and even violence.

Two rescue workers leave at the same time to find an injured hiker. The first walks 25 west of north at 3.5 mi/h, and the second walks 36 east of north at 2.5 mi/h. After 2 hours, the second worker finds the hiker and radios the first worker for help. If the first worker jogs directly to the second worker at 6 mi/h, how long will it take for her to arrive?
After 2 hours, the second rescue worker finds the injured hiker and radios the first worker for help. The first worker arrives in approximately 28.5 minutes after jogging directly to the second worker at 6 mph.
We can start by finding the distances each worker covers in 2 hours.
For the first worker:
Distance = rate × time
Distance = 3.5 × 2 = 7 miles
For the second worker:
Distance = rate × time
Distance = 2.5 × 2 = 5 miles
Now we can use trigonometry to find the horizontal and vertical components of the first worker's displacement while walking:
Horizontal component = 7 × sin(25°) ≈ 3.01 miles
Vertical component = 7 × cos(25°) ≈ 6.30 miles
Similarly, we can find the horizontal and vertical components of the second worker's displacement:
Horizontal component = 5 × sin(54°) ≈ 4.07 miles
Vertical component = 5 × cos(54°) ≈ 3.62 miles
We can now find the horizontal and vertical components of the distance between the two workers:
Horizontal component = 3.01 - 4.07 ≈ -1.06 miles
Vertical component = 6.30 - 3.62 ≈ 2.68 miles
The distance between the two workers is the hypotenuse of a right triangle with these components as its legs:
Distance = √((-1.06)² + (2.68)²) ≈ 2.85 miles
Finally, we can find the time it takes for the first worker to cover this distance at 6 mi/h:
Time = Distance ÷ rate
Time = 2.85 ÷ 6 ≈ 0.475 hours or 28.5 minutes
Therefore, it will take the first worker about 28.5 minutes to arrive.

Function f is an exponential function
By what factor does the output value increase as each input value increases by 1?
Answer:
4
Step-by-step explanation:
You are given a table of function values in which x increases by 2, and you want to know the factor by which f(x) increases when x increases by 1.
FactorLet k represent the factor by which f(x) increases when x increases by 1. This means ...
f(2) = k·f(1)
f(3) = k·f(2) = k·(k·f(1)) = k²·f(1)
64 = k²·4
k² = 64/4 = 16
k = √16 = 4
The output value increases by a factor of 4 as the input value increases by 1.
__
Additional comment
The table values would also be obtained if the factor of increase were -4. That is, f(x) = -(-4)^x would give the same table. In that case, f(x) would not be a continuous function.

Aircraft A has 105 more seats than aircraft B. If their total number of seats is 519, find the number of seats for each aircraft.
Aircraft A has how many seats?
Aircraft A has 312 seats.
Let's assume that Aircraft B has x seats.
According to the given information, Aircraft A has 105 more seats than Aircraft B. So, the number of seats in Aircraft A can be expressed as x + 105.
The total number of seats in both aircraft is 519, which can be represented by the equation:
x + (x + 105) = 519
Simplifying this equation, we have:
2x + 105 = 519
Subtracting 105 from both sides, we get:
2x = 414
Dividing both sides by 2, we find:
x = 207
Therefore, Aircraft B has 207 seats.
To find the number of seats in Aircraft A, we substitute the value of x back into the expression x + 105:
Aircraft A = 207 + 105 = 312
Hence, Aircraft A has 312 seats.

find the rate at which a spherical ballon is increasing if the surface area is increasing at 5 cm²/s when the radius of the spherical balloon is 4cm
The rate at which the spherical balloon is increasing is calculated as approximately 0.049 cm/s.
How to Determine the Rate the Surface Area of the Spherical Balloon is Increasing?Let's use the formula for the surface area of a sphere:
S = 4πr²
where S is the surface area and r is the radius.
Differentiating both sides of the equation with respect to time t, we get:
dS/dt = 8πr dr/dt
where dS/dt is the rate of change of surface area, and dr/dt is the rate of change of the radius with respect to time.
We are given that dS/dt = 5 cm^2/s when r = 4 cm. Substituting these values into the equation above, we get:
5 = 8π(4) dr/dt
Simplifying, we get:
dr/dt = 5/(32π) cm/s ≈ 0.049 cm/s

Please help what is the slope of the line?
Answer:
-5/4
Step-by-step explanation:
Let \((x_1,y_1)=(-4,4)\) and \((x_2,y_2)=(0,-1)\). The slope of the line would be:
\(\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{-1-4}{0-(-4)}=\frac{-5}{4}=-\frac{5}{4}\)
Answer: -5/4
Step-by-step explanation:
To find the slope between two points, you can use the formula:
Slope = (y2 - y1)/(x2 - x1)
Using the points (0, -1) and (-4, 4), we can substitute the coordinates into the formula:
slope = (4 - (-1))/(-4 - 0)
slope = (4 + 1)/(-4)
slope = 5/-4
Therefore, the slope between the two points is -5/4.
The height of XYZ is the distance from the point Y to XZ find the area of the triangle round your answer to the nearest 10th if necessary HELPPP PLEASE
Answer:
Area of ΔXYZ = 10 square units
Step-by-step explanation:
Area of the triangle XYZ = \(\frac{1}{2}(\text{Height})(\text{Base})\)
Height of the triangle = AY
Base of the triangle = XZ
To get the length of any segment we will use the formula,
d = \(\sqrt{(y_2-y_1)^2+(x_2-x_1)^2)}\)
Here \((x_1,y_1)\) and \((x_2,y_2)\) are the endpoints of the segment.
Length of AY = Distance between (-1, 4) and (3, 6)
= \(\sqrt{(6-4)^2+(3+1)^2}\)
= \(\sqrt{20}\)
Length of XZ = \(\sqrt{(6-2)^2+(-2-0)^2}\)
= \(\sqrt{20}\)
Area of ΔXYZ = \(\frac{1}{2}(\sqrt{20})(\sqrt{20})\)

Here is a diagram of a person standing next to a tree.
The diagram shows two centimeter rulers.
The tree and the person are drawn to the same scale.
The person is approximately 1.65 m tall.
Using the scale diagram, estimate the height of the tree in meters
Answer:
9.9 m
Step-by-step explanation:
According to the scale the person is 2 cm tall, and the tree is 12 cm tall.
So we know that the tree is 6 times taller than the person because,
12 cm = 6 x 2 cm
The actual height of the person is 1.65 m.
Since we know that the tree is 6 times taller than the person, we can find the height of the tree to be
6 x 1.65 m = 9.9 m
