formula to calculate variance​

Answer:

[tex] m\angle PRQ =49\degree [/tex]

Step-by-step explanation:

[tex] m\angle PSQ = 360\degree - (128\degree + 134\degree )[/tex]

[tex] m\angle PSQ = 360\degree - 262\degree [/tex]

[tex] m\angle PSQ = 98\degree [/tex]

Now, by inscribed angle theorem:

[tex] m\angle PRQ = \frac{1}{2} \times m\angle PSQ [/tex]

[tex] m\angle PRQ = \frac{1}{2} \times 98\degree [/tex]

[tex] m\angle PRQ =49\degree [/tex]

Answer: 65.4

V = pi r^2 h/3

V = pi (2.5^2) (10/3)

V = pi (6.25) (3.33)

V = 65.4

Answer:

[tex]v = \pi {r}^{2} \frac{h}{3} = {2.5}^{2} \times 3.14 \times \frac{10}{3} = 65.416[/tex]

Answer:

B > A

Step-by-step explanation:

B and A are both in between 0 and 1 on a number line.

On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.

Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)

Multiply the original price by 80%

36 x 0.8 = 28.80

The sale price is £28.80

Answer:

36

Step-by-step explanation:

The formula of LCM is LCM(a,b) = ( a × b) / GCF (a,b)

The Greatest Common Factor of (9,12) = 3

Therefore

LCM of 9 and 12 = (9 × 12) / 3

= 108/3 = 36

LCM of 9 and 12 = 36

Irrespective of the method, the solution to our question LCM of 9 and 12 is the same.

Therefore, LCM of 9 and 12 is 36

180-148=32

90-32=58

180-58=122

Answer:

x = 4

Step-by-step explanation:

Given

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]

Multiply through by (x + 3)(x + 4) to clear the fractions

3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side

3x + 9 - x - 4 = x + 9

2x + 5 = x + 9 ( subtract x from both sides )

x + 5 = 9 ( subtract 5 from both sides )

x = 4

Answer:

28 years

Step-by-step explanation:

The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value

Answer:

(B) 80

Step-by-step explanation:

Answer:

n^2 + 6n + 1

Step-by-step explanation:

Firstly, we have to evaluate AB

What we have to do is to multiply A and B

We have this as;

n(2n + 6) = 2n^2 + 6n

Now, we have to subtract the value of C from here and that is;

(2n^2 + 6n) - (n^2 - 1)

2n^2 + 6n - n^2 + 1

= 2n^2 -n^2 + 6n + 1

= n^2 + 6n + 1

Answer:

1442.9 = 1.4429 x 10 ^1000

Step-by-step explanation:

PEMDAS

4.3 × 107 + 9.1 × 108 = _____ x 10 ^----

(4.3 × 107) + (9.1 × 108) = _____ x 10 ^---

460.1 + 982.8 = _____ x 10 ^----

1442.9 = 1.4429 x 10 ^1000

This is the right answer, I think you may have forgotten to put the ^.  

Answer:

9.53 × 108

Step-by-step explanation:

Make sure both numbers have the same exponent

4.3 × 107 = 0.43 × 108

Then add the coefficients

0.43 × 108 + 9.1 × 108 = 9.53 × 108

Answer: Figure A to Figure B is a scale factor of 0.5

Step-by-step explanation:

It's not too hard to figure out scale factor, since the two shapes are the same aside from their scale. Notice how Figure A is 4 units tall, and that Figure Bis 2 units tall. From one figure to another, use the equation Figure B/Figure A to find the scale factor. Although you won't really need to memorize all this, you can count the amount of units on your fingers and figure it out from there.

Answer:

The figure should be 56 units squared.

Step-by-step explanation:

The long side is 14 units long (6+6+2) and the short side is 4 units long, so 14 multiplied by 4 is 56.

Answer:

468

Step-by-step explanation:

Employee : instructor = 24 : 2

If there are 39 instructors

Employee = x

Employee : instructor = x : 39

Equate both ratios

24 : 2 = x : 39

24/2 = x/39

Cross product

24 * 39 = 2 * x

936 = 2x

x = 936/2

x = 468

Employees = x = 468

Answer:

x=11

mMN=65

mNP=115

mNQP=245

Step-by-step explanation:

10x-45=6x-1

4x=44

x=11

mMN 6(11)-1=65/ 10(11)-45=65

mNP 180-65=115

mNQP 65+115+65=245

Answer:

f(g(3)) = 26

Step-by-step explanation:

f(g(3))

g(3) = 2x + 3

= 2(3) + 3

= 6 + 3

= 9

f(9) = 3x - 1

= 3(9) - 1

= 27 - 1

= 26
