Answer:
11.7 (3 s.f.)
Step-by-step explanation:
Given information:
∠CAB = 90°∠ABC = 52°AC = 9.2As one of the given angles is 90°, the triangle is a right triangle.
Draw the triangle using the given information (see attached) to help visualize the problem.
To calculate the length of BC, use the sine trigonometric ratio:
\(\sf \sin(\theta)=\dfrac{O}{H}\)
where:
\(\theta\) is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)From inspection of the attached triangle:
\(\theta\) = 52°O = AC = 9.2H = BCSubstitute the values into the formula and solve for BC:
\(\implies \sf \sin(52^{\circ})=\dfrac{9.2}{BC}\)
\(\implies \sf BC=\dfrac{9.2}{\sin(52^{\circ})}\)
\(\implies \sf BC=11.67496758...\)
\(\implies \sf BC=11.7\:\:(3 \:s.f.)\)
Therefore, the length of BC is 11.7 (3 s.f.).

(10y - 7
Answers
Answer:
x = 4 and y = 15
Step-by-step explanation:
Opposite sides of parallelogram are equal
Opposite sides of parallelogram are equaltherefore,
13x + 15 = 19x - 9
15or 15 + 9 = 19x - 13x
or 24 = 6x
or 24÷6 = X = 4
adjacent angles = 180°
therefore,
(10y - 37) + (4y + 7) = 180
or 10y - 37 + 4y + 7 = 180
or 14y = 180 + 37 - 7
or 14y = 210
or y = 210 ÷ 14
or. y = 15

Find the equation of the line that passes through the given point and has the given slope. Express your answer in slope-intercept form.1(3,0), m= -8
Answers
Given the word problem, we can deduce the following information:
1. Point (3,0)
2. m=-1/8
To find the slope-intercept form of the equation, we use the formula:
\(y=mx+b\)where:
m=slope
b=y-intercept
First, we plug in x=3, y =0, and m=-1/8 into y=mx+b to find the value of b:
\(\begin{gathered} y=mx+b \\ 0=-\frac{1}{8}(3)+b \\ \text{Simplify and rearrange} \\ b=\frac{3}{8} \end{gathered}\)Then, we plug in b=3/8 and m=-1/8 into the slope-intercept form formula:
\(\begin{gathered} y=mx+b \\ y=-\frac{1}{8}x+\frac{3}{8} \end{gathered}\)Therefore, the answer is:

Choose the number that is closest to the mean of the distribution
Answers
The mean of the distribution is 3
What is arithmetic mean?Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean. One of the basic methods used to acquire a result, the term "Mean" is commonly used in the field of statistics.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
According to the first graph,
Given the bar of observations as :
0, 5, 6, 3, 1, 1, 3, 6, 4, 1
Here the Sum of Observations = 30
And the total number of observations = 10
The mean of the distribution = 30/10
The mean of the distribution = 3
According to the second graph,
Given the bar of observations as :
0, 1, 3, 3, 9, 0, 9, 4, 4, 1
Here the Sum of Observations = 34
And the total number of observations = 10
The mean of the distribution = 34/10
The mean of the distribution = 3.4
The mean of the distribution = 4 (closest)

Answer: w = 9
Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.
18 + 4w = 6w
4w + 18 = 6w
Now we subtract 18 from both sides.
When we simplify, we get that w = 9.
Step-by-step explanation:
Hope this helps =)
Answer:
w = 9
Step-by-step explanation:
Rearrange terms
4w + 18 = 6w
Subtract 18 from both sides of the equation
4w+18-18 = 6w -18
Simplify
4w=6w-18
Subtract 6w from both sides of the equation
4w-6w=6w-18-6w
Simplify
-2w=-18
Divide both sides of the equation by the same term

Answers
The area of the sidewalk is 388 square feet.
How to find the area of the sidewalkTo find the area of the sidewalk you can find the area of each individual shape and add them together.
Area of the first triangle T = (1/2) x 6 ft x 11 ft = 33 sq. ft.
Area of the second triangle = (1/2) x 6 ft x 18 ft = 54 sq. ft.
Area of the rectangle = 6 ft x 30 ft = 180 sq. ft.
Area of the square = 11 ft x 11 ft = 121 sq. ft.
Therefore, the total area of the sidewalk is:
33 sq. ft. + 54 sq. ft. + 180 sq. ft. + 121 sq. ft. = 388 sq. ft.
So, the area of the sidewalk is 388 square feet.

C} The range is greater for the boys, B) The mean is greater for the girls
D}The range is greater for the boys, B) The mean is greater for the boys
Answers
The range is greater for the girls and the mean is greater for the girls. So, correct option is B.
A) The statement "The range is greater for the girls" is true. The range is the difference between the highest and the lowest values in a data set.
Looking at the line plots, the highest value for the boys is 10, and the lowest is 3, giving a range of 7 hours. The highest value for the girls is 9, and the lowest is 5, giving a range of 4 hours. Therefore, the range is greater for the boys.
B) The mean is the sum of all values divided by the total number of values. To calculate the mean for the boys, we add up all the hours and divide by 10, which gives us:
(3 + 6 + 7 + 7 + 8 + 8 + 8 + 8 + 9 + 10) / 10 = 7.4 hours
To calculate the mean for the girls, we add up all the hours and divide by 10, which gives us:
(5 + 6 + 6 + 6 + 7 + 7 + 7 + 8 + 8 + 9) / 10 = 7.1 hours
Therefore, the mean for the boys is 7.4 hours and the mean for the girls is 7.1 hours, so the statement "The mean is greater for the girls".
So, correct option is B.

9. A has some amount of money with him. He gave one half of one third from that amount One half of the amount received by B is 20. What is the amount that A originally had?
Answers
Using the expression 5x/12 = 20, the amount that A originally had was $48.
We have,
Let x be the amount of money that A originally had.
Then, A gave away 1/2 x 1/3 = 1/6 of the amount, which is equal to x/6.
The amount received by B is 1/2 of the remaining amount,
which is (x - x/6)/2 = 5x/12.
We know that 5x/12 = 20,
Solving for x.
5x/12 = 20
5x = 240
x = 48
Therefore,

Three-year-old boys in the United States have a mean height of 38 inches and a standard deviation of 2 inches, and 10-year-old girls have a mean height of 54.5 inches and a standard deviation of 2.5 inches.
Mrs. Davis has two children: a 3-year-old boy 43 inches tall and a 10-year-old girl 57 inches tall.
Which of Mrs. Davis' children is more unusually tall for his
or her age and gender? Explain, showing any calculations you perform.
Answers
The 3-year-old boy is more unusually tall for his age and gender than the 10-year-old girl.
To solve this problemA z-score calculates how many standard deviations an observation is from the mean. An observation is said to be above the mean if the z-score is positive, while it is said to be below the mean if the z-score is negative.
For the 3-year-old boy, the z-score is:
z = (43 - 38) / 2 = 2.5
The z-score for the 10-year-old girl is:
z = (57 - 54.5) / 2.5 = 1
The 3-year-old boy has a higher z-score than the 10-year-old girl, indicating that he is more unusually tall for his age and gender. This is due to his height, which is higher than the average for his age group 38 inches .
Therefore, the 3-year-old boy is more unusually tall for his age and gender than the 10-year-old girl.

C. Purchase of new vehicle
D. Receipt of dividend from investment
Answers
Answer:
The answer is A. Depreciation.
A cash budget is a financial statement that projects a company's future cash inflows and outflows. It is used to help the company manage its cash flow and avoid running out of money. The cash budget includes all of the company's expected cash receipts and payments, including sales, purchases, expenses, and taxes. Depreciation is not a cash flow, so it does not appear on a cash budget.
Depreciation is an accounting concept that allows companies to spread the cost of an asset over its useful life. It is not a cash expense, because the company does not actually pay out any money when it depreciates an asset. Instead, the company reduces the value of the asset on its balance sheet.
The cash budget is a valuable tool for businesses of all sizes. It can help businesses to plan for future cash needs, avoid running out of money, and make sound financial decisions.

When thirteen is reduced by two-thirds of a number, the result is 7. Find the number.
The number is
Answers
Answer:
30Step-by-step explanation:
Let,
The req. number be = x
So,
Two - thirds of the number
\( = \frac{2}{3} x\)
Then, it is reduced by 13
\( = \frac{2}{3} x - 13\)
After that,
The req. result we get is = 7
Therefore,
By the problem,
\( = > \frac{2}{3} x - 13 = 7\)
(On putting like terms on one side)\( = > \frac{2}{3} x = 7 + 13\)
(On Simplification)\( = > \frac{2}{3}x = 20\)
(On multiplying both sides with 3/2)\( = > \frac{2}{3} x \times \frac{3}{2} = 20 \times \frac{3}{2} \)
(On Simplification)=> x = 30
Hence,
The req. number is 30.
Given that :
Thirteen is reduced by two-thirds of a number. And their result is 7.To Find :
The number.Solution :
Let's assume the number as x
According to the question :
\(\qquad \sf \: { \dashrightarrow \dfrac{2}{3}x - 13 = 7 }\)
Adding 13 to both sides we get :
\(\qquad \sf \: { \dashrightarrow \dfrac{2}{3}x - 13 + 13 = 7 + 13 }\)
\(\qquad \sf \: { \dashrightarrow \dfrac{2}{3}x = 20 }\)
Now, Multiplying both sides by \( \dfrac{3}{2} \) we get :
\(\qquad \sf \: { \dashrightarrow \dfrac{2}{3}x \times \dfrac{3}{2} = 20 \times \dfrac{3}{2} }\)
\(\qquad \sf \: { \dashrightarrow \dfrac{ \cancel2}{ \cancel3}x \times \dfrac{{ \cancel3}}{ \cancel{2}} = \cancel{20} \times \dfrac{3}{ \cancel{2}} }\)
\(\qquad \sf \: { \dashrightarrow x = 10 \times {3} }\)
\(\qquad \bf \: { \dashrightarrow x = 30 }\)
Therefore, The number is 30.
