If we define left of the graph as "negative" and right of the graph "positive", we can see how most data points are shifted to the left.
∴ It would be negatively skewed.
It would not be 2. Symmetric because if we draw a line of symmetry, it is in fact unsymmetrical.
It would not be 3. Positively skewed because the data would be grouped towards the right.
It would not be 4. Exponentially skewed because the data is not strictly increasing bigger and bigger.

Right triangle FHG is shown. The sine of angle F is 0.53. What is the cosine of Angle h ?
Answers
Given:
Given that FGH is a right triangle. The sine of angle F is 0.53.
We need to determine the cosine of angle H.
Cosine of angle H:
Given that the sine of angle F is 0.53
This can be written as,
[tex]sin F=0.53[/tex]
Applying the trigonometric ratio, we have;
[tex]\frac{HG}{FH}=0.53[/tex] ----- (1)
Now, we shall determine the value of cosine of angle H.
Let us apply the trigonometric ratio [tex]cos \ \theta=\frac{adj}{hyp}[/tex], we get;
[tex]cos \ H=\frac{HG}{FH}[/tex] ----- (2)
Substituting the value from equation (1) in equation (2), we get;

Jim rode at average speed of 12 mph for 2 hours. Then, he
walked at average speed of 3 mph for 0.5 hour. What was the
total distance covered by Jim?
miles
Answers
Answer:
25.5 miles
Step-by-step explanation:
The distance is equal to speed multiplied by time. When Jim rode at 12 mph for 2 hours, that means her rode for 24 miles(12*2), then he walked at 3 mph for half an hour, that means he walked for 1.5 miles(3*1/2). Add them both together, you get 25.5 miles.
The total distance covered by Jim is 25.5 miles.
Calculating distancesTo find the total distance covered by Jim, we need to add the distances covered while riding and walking.
Distance covered while riding = Speed * Time = 12 mph * 2 hours = 24 milesDistance covered while walking = Speed * Time = 3 mph * 0.5 hours = 1.5 milesTotal distance covered = 24 miles + 1.5 miles = 25.5 miles
Therefore, the total distance covered by Jim is 25.5 miles.

The exterior walls and roof of a barn are to be painted. The barn is in the shape of a rectangular prism, with an isosceles triangular prism for a roof. Calculate the total area to be painted. PLEASE HELP! I WILL MARK YOU BRAINLIEST!
Answers
Given:
The rectangular prism has a length of 25 feet, a width of 10 feet and a height 55 feet.
The triangular prism has a base length of 25 feet, a height of 8 feet, and a prism height of 55 feet.
To find:
The total area to be painted.
Solution:
There are 4 external surfaces for the rectangular prism and 4 external surfaces for the triangular prism.
The rectangular prism has 4 rectangles out which there are 2 sets of similar rectangles.
There are two rectangles with lengths of 25 feet and widths of 10 feet while the other two rectangles have lengths of 55 feet and widths of 10 feet.
The area of a rectangle with a length of 25 feet and a width of 10 feet [tex]= 25(10)= 250[/tex] square ft.
The area of two such rectangles [tex]= 2(250) = 500[/tex] square feet.
The area of a rectangle with a length of 55 feet and a width of 10 feet [tex]= 55(10)= 550[/tex] square feet.
The area of two such rectangles [tex]= 2(550) = 1100[/tex] square feet.
The triangular prism has 2 triangles and 2 rectangles.
The triangles have base lengths of 25 feet and heights of 8 feet while the rectangles have lengths of 55 feet and heights of 14.8 feet.
The area of a triangle with a base length of 25 feet and a height of 8 feet [tex]= \frac{1}{2}(25)(8)= 100[/tex] square feet.
The area of two such triangles [tex]=2(100)= 200[/tex] square feet.
The area of a rectangle with a length of 55 feet and a width of 14.8 feet [tex]= 55(14.8)= 814[/tex] square feet.
The area of two such rectangles [tex]= 2(814) = 1628[/tex] square feet.
The total area to be painted [tex]=500+1100+200+1628 = 3128[/tex] square feet.
So an area of 3128 square feet is to be painted.
An area of 3128 square feet is to be painted.
The rectangular prism has a length of 25 feet, a width of 10 feet and a height 55 feet.
The triangular prism has a base length of 25 feet, a height of 8 feet, and a prism height of 55 feet.

The total area to be painted.
There are 4 external surfaces for the rectangular prism and 4 external surfaces for the triangular prism.
The rectangular prism has 4 rectangles out which there are 2 sets of similar rectangles.
There are two rectangles with lengths of 25 feet and widths of 10 feet while the other two rectangles have lengths of 55 feet and widths of 10 feet.
The area of a rectangle with a length of 25 feet and a width of 10 feet = 25(10)= 250 square ft.
The area of two such rectangles = 2(250) = 500 square feet.
The area of a rectangle with a length of 55 feet and a width of 10 feet = 55(10)= 550 square feet.
The area of two such rectangles = 2(550) = 1100 square feet.
The triangular prism has 2 triangles and 2 rectangles.
The triangles have base lengths of 25 feet and heights of 8 feet while the rectangles have lengths of 55 feet and heights of 14.8 feet.
The area of a triangle with a base length of 25 feet and a height of 8 feet = (1)/(2)(25)(8)= 100 square feet.
The area of two such triangles =2(100)= 200 square feet.
The area of a rectangle with a length of 55 feet and a width of 14.8 feet = 55(14.8)= 814 square feet.
The area of two such rectangles = 2(814) = 1628 square feet.
The total area to be painted =500+1100+200+1628 = 3128 square feet.
So an area of 3128 square feet is to be painted.

d. 81 pi units2
PLEASE HURRY!! I HAVE LIMITED TIME!! :)
Answers
Given:
Given that the radius of the circle is 9 units.
The measure of the angle JHG is 160°
We need to determine the area of the shaded sector of the circle.
Area of the circle:
The area of the circle can be determined using the formula,
[tex]A=(\frac{\theta}{360}) \pi r^2[/tex]
where r is the radius
Substituting r = 9 and [tex]\theta=160[/tex], we get;
[tex]A=(\frac{160}{360}) \pi (9)^2[/tex]
Simplifying, we get;
[tex]A=(\frac{160}{360}) \pi (81)[/tex]
[tex]A=36 \pi[/tex]
Thus, the area of the shaded sector of the circle is 36π units²
Hence, Option a is the correct answer.

Which equation is a correctly written thermochemical equation?
C3H8 (g) + 5O2 (g)→3CO2 (g) + 4H2O (l) , ΔH= −2,220 kJ/mol
Fe (s) + O2 (g)→Fe2O3 (s) , ΔH= −3,926 kJ
NH4Cl→NH4 + + Cl−
2C8H18 + 25O2→16CO2 + 18H2O , ΔH= −5,471 kJ/mol
Answers
Correctly written thermochemical equations include gaseous, liquid, or solid state indications as well as the enthalpy change, ΔH. Out of the presented options, the equations for C3H8(g), Fe(s), and 2C8H18 correctly represent thermochemical equations, but NH4Cl does not due to lacking these features.
Explanation:The question is asking which equation is a correctly written thermochemical equation. A thermochemical equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH.
Looking at the given equations, the first is:
C3H8(g) + 5O2(g)→3CO2(g) + 4H2O(l) , ΔH= −2,220 kJ/mol. This is a correct thermochemical equation.
The second equation is:
Fe(s) + O2(g)→Fe2O3(s) , ΔH= −3,926 kJ. This is also a correct thermochemical equation.
The third equation lacks the gaseous, liquid, or solid state indications as well as the ΔH value, therefore it is not a thermochemical equation.
The fourth equation, 2C8H18 + 25O2→16CO2 + 18H2O , ΔH= −5,471 kJ/mol, is definitely an example of a correct thermochemical equation.

Ms. van Vugt is making brownies. Her recipe calls for 1/2 cup of milk for 12 brownies. She is making 48 brownies. How much milk does she need? (HINT: How many cups are in a pint?) *
Answers
Answer: Ms. Van Vugt will need 2 cups of milk or 1 pint of milk to make 48 brownies.
Step-by-step explanation: For this situation, we know for every 12 brownies she will use 1/2 cup of milk. So we can count up for every 12 brownies.
12 brownies = 1/2 cup of milk
24 brownies = 1 cup of milk
36 brownies = 1 1/2 cup of milk
48 brownies = 2 cups of milk
So, Ms. Van Vugt will need 2 cups of milk or 1 pint of milk to make 48 brownies.

A baseball is hit so that its height in feet after t seconds is s(t) = - 4t"" + 20t+2.
(a) How high is the baseball after 1 second?
(b) Find the maximum height of the baseball.
Answers
Answer with Step-by-step explanation:
We are given that
Height of ball after t seconds is given by
[tex]s(t)=-4t^2+20t+2[/tex]
a.Substitute the value of t=1
[tex]s(1)=-4(1)+20(1)+2=-4+20+2=18 ft[/tex]
b.Differentiate w.r.t x
[tex]s'(t)=-8t+20[/tex]
[tex]s'(t)=0[/tex]
[tex]-8t+20=0[/tex]
[tex]8t=20[/tex]
[tex]t=\frac{20}{8}=2.5[/tex]
Again differentiate w.r.t t
[tex]s''(t)=-8<0[/tex]
Hence, the height is maximum at t=2.5 s
[tex]s(2.5)=-4(2.5)^2+20(2.5)+2=27[/tex]
Maximum height of the baseball=27 ft
Which equation represents a line with a slope of 3 and y-intercept of -4?
a y = 3x -4
b y =4x −3
c y=−3x +4
d y=−4x + 3
Answers
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
You know:
m = 3
b = -4 So substitute/plug it into the equation
y = mx + b
y = 3x + (-4)
y = 3x - 4 Your answer is a
The equation representing a line with a slope of 3 and a y-intercept of -4 is y = 3x - 4. Hence, the correct option is (a).
The student's question pertains to finding the equation of a line with a given slope and y-intercept. In the slope-intercept form of a linear equation, which is y = mx + b, the m represents the slope, and the b represents the y-intercept. Therefore, for a line with a slope of 3 and a y-intercept of -4, the corresponding equation would be y = 3x - 4.
So, the correct answer is:
y = 3x - 4
This is because it directly shows a slope (m) of 3 and a y-intercept (b) of -4, which matches the line properties the question is asking for.

Final answer:
To calculate Mr. Rich's take-home pay, add together the regular and overtime pay, then subtract the deductions. The result is a take-home pay of $10,737 that is option A is correct.
Explanation:
The student is asking how to calculate the take-home pay for Mr. Rich after deductions from his income. To find the take-home pay, we first add together Mr. Rich's regular pay and overtime pay to get his total earnings. Then, we subtract the deductions to find the amount he takes home.
Regular pay: $9,278
Overtime pay: $2,132
Total earnings before deductions: $9,278 + $2,132 = $11,410
Deductions (taxes and loan): $673
Take-home pay: $11,410 - $673 = $10,737

There are a number of different ways to handle this. One is to target a 100% response rate, although in doing this care has to be taken in how it is achieved to avoid biasing the responses by changing them! By way of a silly example, if I offered everyone who responds to the survey a lifetime’s supply of ice-cream to boost the response rate, and the survey includes questions about future purchases of ice-cream, that may well impact on the answers. Similarly, cajoling employees into completing an engagement survey may have a negative effect on their answers.
Non-response does not always have a negative effect on survey result (there is a large body of research in this area: Curtin, Presser, and Singer 2000 ; Keeter et al. 2000; , and Earl, “The Practice of Social Research”). Anything over 50% is usually sufficient, and over 70% is viewed as a very good response rate. There are a number of reasons for survey non-response:
Awareness (people were not aware of the survey due to communication failure).
Capability (people do not have the knowledge/competence/tools to complete the survey).
Motivation (people are aware and able, but unmotivated/unwilling/refusing).

What is the equation of the line that passes through (-2, 2) and (1, -4)?
y=2x-2
y=-2x-4
y=-2x-2
y= 2x+4
Answers
Answer:
y = - 2x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ = (- 2, 2) and (x₂, y₂ ) = (1, - 4)
m = [tex]\frac{-4-2}{1+2}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 2), then
2 = 4 + c ⇒ c = 2 - 4 = - 2
y = - 2x - 2 ← equation of line
