The total age of the three children are = 37years

<h3>Calculation of the total age of children</h3>

The product of the ages of three children is = 1872.

Let take child 1 = x

child 2 = x

child. 3 = x

Therefore, the age of three children = x³= 1872

Therefore;

x =  \sqrt[3]{1872}

X = 12.32448

The age of the middle child = 12.32448 + 12.32448

= 24.64896/2

= 12.32448

Therefore the sum of their ages = 12.32448 + 12.32448 + 12.32448 = 37years.

A Blimp is 400 feet in the air. There is an angle of depression of 40 degrees to a football stadium. How far is the Blimp from t
VMariaS [17]

Answer:

Step-by-step explanation:

The diagram of the stadium and the blimp is shown in the attached photo. A right angle triangle, ABC is formed. Angle A is alternate to the angle of depression. This mean that they are equal. So angle A =40 degrees.

The distance of the the Blimp from the stadium is x feet which is the hypotenuse of the triangle.

Applying trigonometric ratio,

Sin 40 = 400/x

xsin40 = 400

x = 400/sin40 = 400 / 0.6428

x = 622.3 feet

Factor the expression.
g100num [7]

Answer:

(x + 1) (3 x^2 + 1)

Step-by-step explanation:

Factor the following:

3 x^3 + 3 x^2 + x + 1

Factor terms by grouping. 3 x^3 + 3 x^2 + x + 1 = (3 x^3 + 3 x^2) + (x + 1) = 3 x^2 (x + 1) + (x + 1):

3 x^2 (x + 1) + (x + 1)

Factor x + 1 from 3 x^2 (x + 1) + (x + 1):

Answer:  (x + 1) (3 x^2 + 1)

a rectangular prism measures 3 in by 8 in by 9 in. what is the side length of a cube with the same volume?
Novay_Z [31]

Answer:

6 in.

Step-by-step explanation:

Rectangular prism

V = lwh       l = 8   W = 3    h = 9

  = 8(3)(9)

  = 216

Cube

V = s^{3}   where s = length of side

216 = s^{3}

s = \sqrt[3]{216}  = 6

A friend of yours, a senior, took the Graduate Record Exam in September and scored in the 99th percentile. In February, your fri
soldi70 [24.7K]

His/her lowered score was most likely due to statistical regression.

<h3>How to determine the reason?</h3>

The missing options in the question are:

A. compensation rivalry  B. Demoralization C.  Differential selection

D.  Testing E.  Statistical regression

From the question, we have:

  • September = 99th percentile
  • February = 90th percentile

A change (whether higher or lower) in the score is caused by statistical regression.

This is so because several variables could attribute to the change in the score.

The relationship between these variables is referred to as statistical regression
