The option that would give the estimated volume of the Pyramid of Giza is = [tex]\frac{53,000 . 150 }{3}[/tex]

A pyramid is a 3-dimensional shape that is made up of a polygonal base and 4 triangular faces. The 4 triangular faces are joined at a vertex. Types of pyramids include a square pyramid, rectangle pyramid, triangle pyramid.

The volume of a pyramid is the amount of space that is a three-dimensional shape.

Volume of a pyramid = 1/3 x (base area x height)

1/3 x (53,000. 150)

= [tex]\frac{53,000 . 150 }{3}[/tex]

The  mean can be written as mean A= x+ y/2

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.

Only numerical variables—regardless of whether they are discrete or continuous—can be used to determine the mean. Simply dividing the total number of values in a data set by the sum of all of the values yields it.

The mean formula is

= {Sum of Observation} ÷ {Total numbers of Observations}

Given:

mean A of two numbers, x and y

So, the mean can be written as

mean A= x+ y/2

The value of the part of 20 that is 46% is 9.2.

Percentage is simply a number or ratio expressed as a fraction of 100.

It is expressed as;

Percentage = ( Part / Whole ) × 100%

Given the data in the question;

Plug the given values into the above formula and solve for the part.

Percentage = ( Part / Whole ) × 100%

46% = ( Part / 20) × 100%

46/100 = ( Part / 20 ) × 100/100

46/100 = ( Part / 20 ) × 1

46/100 = Part / 20

Cross multiply

46 × 20 = Part × 100

920 = Part × 100

Part = 920/100

Part = 9.2

Therefore, 9.2 is 46 percent of 20.

The average frequency of people hearing the spot on the radio station is equal to 5.

Average frequency can be defined as the average number of times an individual is exposed to an Advertising schedule.

Average frequency can be calculated by using the formula;

average frequency = total / n

As 4000 people heard the spot 6 times and 2000 people heard it three times; therefore

n = 4000 + 2000 = 6000

total = number × frequency = (6 × 4000) + (3 × 2000) = 24000 + 6000 = 30,000

Substituting these values in the equation;

average frequency = 30,000 / 6000

average frequency = 5

Hence the average frequency of people hearing the spot on the radio station wkoi is calculated to be 5.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

You want the value of y for various values of x, given that y = -4x +3.

Function evaluating

Put the value of x where x is in the function rule and do the arithmetic.

 y = -4x +3

for x = -2

y = (-4)(-2) +3 = 8 +3 = 11

for x = 0

y = (-4)(0) +3 = 0 +3 = 3

The values of the angles m∠1 and m∠3 is equal to 73°.

A transversal may be defined as a line which cuts a pair of parallel lines and forms several angles. When transversal cuts parallel lines the alternate interior angles are equal as well as the corresponding angles are equal. Also, the pair of vertically opposite angles are equal. From the figure attached. ∠4 = ∠8 as they are corresponding angles. So, m∠8 = m∠4 = 107°. Now, we know that ∠1 and ∠4 formed a pair of linear angles and the sum of the measures of the linear angles is 180°. So,

m∠1 + m∠4 = 180°

We know, m∠4 = 107°

m∠1 = 180° - 107°

m∠1 = 73°

Now, ∠1 and ∠3 are vertically opposite angles, so they are equal as the parallel lines are cut by transversal. Therefore, m∠1 = m∠3

=> m∠1 = 73°

=> m∠3 = 73°
