Answer:
y=5x-12
Step-by-step explanation:
find the slope first which is (8-3)/(4-3)=5
Then that’s your slope.
after that plug the x into the equation I wrote so that means y=5(3)-12 and you should get the y value which is simple enough if you know how to do it.

A teacher calculated the mean of 27 students mark to be 62. A student who later completed the assessment got a mark of 53. What is the new mean of the class, to two decimal places?
Answer:
first of all the average score of students is 62.
and there are 27 students
so full marks scored by students are 27×62= 1674
and 1 new students added to that so his score would be 1674+ 53(his marks)= 1727
so now the mean of students are beause there are one more students so 27+1 = 28 then 28÷1727= 61.6 is the mean now

The diameter of a circle is 12 cm. Find its circumference in terms of pi
Answer:
37.68
Step-by-step explanation:
to get radius divide diameter by 2.
formula for circumference is 2×r×pi.
since we already have the diameter we don't need to ÷ by 2 to get the radius because then we would have to multiply it back again.
pi=3.14.
12×3.14=37.68.

8 more than twice a number is 18.
Answer:
18 + (18 more than) 2x (twice a number) = (is) 8
18+2x=8
2x=-10 (subtract 18 from both sides)
x=-5 (divide both sides by 2)

Factor the following :
Answer:
(6x - 7y)(6x + 7y)
Step-by-step explanation:
36x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
36x² - 49y²
= (6x)² - (7y)²
= (6x - 7y)(6x + 7y)
Answer:
(6x + 7y)(6x - 7y)
Step-by-step explanation:
36x² - 49y²
= (6x)² - (7y)²
= (6x + 7y)(6x - 7y)
In this question we used the identity-
a² - b² = (a + b)(a - b)

Will a 11.5-inch x 18-inch rectangular tray fit in
the box shown? Explain.
Answer:
Option D
Step-by-step explanation:
From the picture attached,
In the parallelogram ABCD,
Length of diagonals AC and BD are equal.
By the property,
"If the lengths of the diagonals of a parallelogram are equal, parallelogram will be a rectangle".
Therefore ABCD is a rectangle.
That means all interior angles of the given rectangle will be 90°.
Now we apply Pythagoras theorem in right triangle ΔABC,
AC² = AB² + BC²
(22)² = (12)² + (BC)²
484 - 144 = (BC)²
BC = √340
BC = 18.44 inches
Dimensions of the given box are 12 inches by 18.44 inches.
Dimensions of the rectangular tray is 11.5 inches by 18 inches.
Since, dimensions of the box are larger than the dimensions of the tray, tray can be adjusted in the box.
Therefore, Option D will be the answer.

A sociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group who say that the most fun way to flirt is in person. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied.
I have attached the complete question.
Answer:
Mean; μ = 1.648
Standard deviation;σ = 0.8610
Step-by-step explanation:
From the image attached, we can see that the probabilities given under the p(x) column are;
0.091
0.334
0.408
0.166
Let's find out if these values give a probability distribution.
ΣP(x) = 0.091 + 0.334 + 0.408 + 0.166
ΣP(x) ≈ 1
Their sum is approximately 1 and they are all between 0 and 1. Thus, it is a probability distribution.
Mean is found by;
μ = ΣxP(x)
From the table attached, x = 0, 1, 2, 3
Thus;
μ = (0 × 0.091) + (1 × 0.334) + (2 × 0.408) + (3 × 0.166)
μ = 1.648
Standard deviation is given by;
σ = √[Σ(x - μ)²•P(x)]
σ = √[((0 - 1.648)² × 0.091) + ((1 - 1.648)² × 0.334) + (2 - 1.648)² × 0.408) + ((3 - 1.648)² × 0.166)]
σ = 0.8610

Michelle will sell her homemade necklaces for $8 each at a craft fair. It costs her $150 for the booth rental at the craft fair.
She made 200 necklaces to sell.
Part A What is the maximum amount, in dollars, of profit Michelle can earn from the sale of her necklaces?
Answer:
$1600
Step-by-step explanation:
just multiply$8 by 200 and I think $1600 is the answer
The maximum amount, in dollars, of profit Michelle, can earn from the sale of her necklaces is $1,450.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
The rent that Michelle pays for the booth at the craft fair is $150. Also, it is mentioned that the selling price of a single necklace is $8, while the number of necklaces that Michelle sells is 200.
The total revenue that Michelle will be able to make from 200 necklaces will be,
The total revenue = $8 × 200 = $1,600
Since profit is the difference between the total revenue and the expenses, therefore, the total profit of the organization can be written as,
Total Profit = $1,600 - $150 = $1,450
Hence, the maximum amount, in dollars, of profit Michelle can earn from the sale of her necklaces is $1,450.

Answer:
2x + 1
Step-by-step explanation:
That person added everything together that was shown which is incorrect. You shouldn't add the 12x + 3 as that should be the end result. You add 3x + 3x + 4x + 2 to get 10x + 2. You then subtract that by 12x +3 which is 2x + 1

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
A = x(x − 4) − (8)(x − 4) − 4(8)
A = x(x − 4) + (8)(x − 4) + 4(8)
A = x(x − 4) + 0.5(8)(x − 4) + 4(8)
Step-by-step explanation:
here .................
Answer:
A. A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Step-by-step explanation:
Total area:
A(t) = x(x - 4)Area of the stage:
A(s) = 0.5(8)(x - 4)Area of the closet:
A(c) = 4(8)Area to be painted:
A = A(t) - A(s) - A(c)A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Correct choice is A
