Answer:

Mean: 8 and MAD: 1.2

Step-by-step explanation:

Given a data with :

Mean = 20 ; mean absolute deviation (MAD) = 3.1

DATA with a low mean and variability Than The above from the options given :

The most appropriate option is : Mean: 8 and MAD: 1.2 ; because both values of the mean and mean absolute deviation are lesser than the value given.

Each of the cuboidal blocks B and D has a volume of 24 cubic units. As a result, choice D is the right response.

What is the formula to find the volume of a cuboidal block?

The formula to find the volume of a cuboidal block is l×b×h.

The dimensions of cuboidal block A are length=6 units, breadth=2 units and height=1 units

Now, the volume of a cuboidal block A=6×2×1=12 cubic units.

The dimensions of cuboidal block B are length=4 units, breadth=2 units and height=3 units

Now, the volume of a cuboidal block B=4×2×3=24 cubic units.

The dimensions of cuboidal block C are length=5 units, breadth=3 units and height=3 units

Now, the volume of a cuboidal block C=5×3×3=45 cubic units.

The dimensions of cuboidal block D are length=6 units, breadth=2 units and height=2 units

Now, the volume of a cuboidal block D=6×2×2=24 cubic units.

The volume of cuboidal blocks B and D is 24 cubic units each. Therefore, option D is the correct answer.

The rectangle TV's width is determined by the formula W = 64.3 inches.

The formula determines a rectangle's diagonal.

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

Let D represent the diagonal of the rectangular TV.

D is now equal to 90 inches.

Let the TV's rectangle size be 63 inches.

Let W be the TV's rectangular width.

And , Diagonal of a Rectangle = √ ( Length )² + ( Width )²

D² = L² + W²

90² = 63² + W²

Subtracting 63² on both sides of the equation , we get

W² = 90² - 63²

On simplifying the equation , we get

W² = 4131

Taking square roots , we get

W = √4131 inches

W = 64.3 inches

Thus , W is equal to 64.3 inches.

Hence, the rectangular TV is 64.3 inches wide.

Answer:

8x+14

Step-by-step explanation:

Answer:

(1/2)x + $5 (Answer A)

Step-by-step explanation:

Two points on the line representing the cost are (8, $9) and (12, $11).

The change in x is 4 (minutes); this is the 'run.'  The change in y is $2 (this is the 'rise').  Thus, the slope of this line is m = rise / run = $2/(4 min), or 1/2 dollar per min.

Applying the slope-intercept formula y = mx + b, we get:

$9 = (1/2)(8) + b, and from this we see that b must be $5.

Then the correct equation is y = (1/2)x + $5.

x=16

Step-by-step explanation:

A straight angle is 180°

you get 180°- 62°=a

then You add up a and 46=b

lastly we know that a triangle's angle is 180° so we get 180°- b

tYou should try it yourself

Answer:

c = 110-degrees

b = 70-degrees

Step-by-step explanation:

for c:

linear pair which means it equals 180-degrees

70 + c = 180 *subtract 70 from both sides*

c = 110

for b:

vertical angles are equal

b = 70-degrees

Step-by-step explanation:

Remark

You are trying to find one of the legs of a right triangle. All you need is the Pythagorean Theorem.

Formula

x^2 + y^2 = c^2

Givens

x = ?

y = 0.9

c = 1.5

Solution

x^2 + 0.9^2 = 1.5^2

x^2 + 0.81 = 2.25         Subtract 0.81 from both sides

x^2 = 2.25 - 0.81

x^2 = 1.44                     Take the square root of both sides

sqrt(x^2) = sqrt(1.44)

x = 1.2

Answer:

B

Step-by-step explanation:

The circumference of a circle can be described as the linear distance round the circle

The circumference of a circle = 2πr or πD

π = 3.14

r = radius

d = diameter

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

π  = circumference / 2r or circumference / D
