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

Factor the following 15v^2+7=38v
Answer:
v = 1/5, 7/3
Step-by-step explanation:
Factor the following 15v² + 7 = 38v
Solution:-15v² + 7 = 38v
15v² - 38v + 7 = 0
15v² - 3v - 35v + 7 = 0
3v(5v - 1) - 7(5v - 1) = 0
(5v - 1)(3v - 7) = 0
So,
Either, 5v - 1 = 0
5v = 1
[tex] { \boxed{\rm \red {v \: = \frac{1}{5}}}} [/tex] (Answer)And, 3v - 7 = 0
3v = 7
[tex] { \boxed{\rm \purple {v \: = \frac{7}{3}}}} [/tex] (Answer)If the standard deviation of a data set were originally 8, and if each value in

Please help, my computer is about to die and this is due in a few minutes. Will mark brainlist if correct.
Answer:
x = 1.5
Step-by-step explanation:
Here, we want to solve for the value of x
By using the tangent from the same point theorem, we have it that;
lh^2 = lj * lk
1^2 = (0.5) * (0.5 + x)
1 = 0.5x + 0.25
1-0.25 = 0.5x
0.5x = 0.75
x = 0.75/0.5
x = 1.5
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)

Can someone help me with math
Answer:
It will cost $12.75 for a 7-mile ride.
Step-by-step explanation:
x = per mile
y = total cost
Equation:
y = 4 + 1.25x
For 7 miles:
y = 4 + 1.25x
y = 4 + 1.25(7)
y = 4 + 8.75
y = 12.75

Mark is going to an awards dinner and wants to dress appropriately. He had one blue shirt, one white dress shirt, one black dress shirt, one pair of black slacks, one pair of grey slacks, and one red tie. All six of marks possible outfits are listed below
Answer:
All the four statements are true , which are -
(A) The subset contains contains of all the outfits that have grey slacks .
(B) The subset contains contains of all the outfits that have grey slacks and red tie .
(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .
(D) The subset contains contains of all the outfits that do not have black slacks .
Step-by-step explanation:
We are given with Outfit 2 , 4 and 6
Outfit 2 - Blue grey red
Outfit 4 - White grey red
Outfit 6 - Black grey red
(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .
(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .
(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .
(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.
Hence , all the options A , B , C , D are correct and describes the subset .
The given question is incomplete , the complete question is attached here -
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

Mark invested $500 in an account that pays 9% annual simple intrest.Make will not make any additional deposits or withdrawls.How much will mark earn on his investment at the end of 7 years
Answer:
$815
Step-by-step explanation:
Given data
Principal= $500
Rate= 9%
TIme= 7 years
The simple interest formula is
A=P(1+rt)
substitute
A= 500(1+0.09*7)
A=500(1+0.63)
A= 500*1.63
A=$815
what is this answer??
Answer:
[tex]20^{\circ}[/tex]
Step-by-step explanation:
We can see here that the two unknown angles are on the straight line . So its measure will be 180° .
[tex]\implies (4x + 20^{\circ})+(x-15^{\circ}) = 180^{\circ} \\\\\implies 5x + 5^{\circ} = 180^{\circ} \\\\\implies 5x = 175^{\circ} \\\\\implies x =\dfrac{175^{\circ}}{5}\\\\\implies x = 35^{\circ} [/tex]
Now the angle F and the angle (x-15)° are vertically opposite angles . So they will be equal .
[tex]\implies x - 15^{\circ} \\\\\implies 35^{\circ} - 15^{\circ} \\\\\implies \boxed{ 20^{\circ} } [/tex]

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

Step-by-step explanation:
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)

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.
