Answer:

Let say 75% of cars older than age = Y years

than 25 % cars of age less than Y Years

Z score corresponding to 25 % = -0.674

Z score = (Value - Mean) /SD

Value = Y

Mean = 8

SD = 3.2

Z score = -0.674

-0.674 = (Y - 8)/3.2

=> Y =5.84 Years

=> Y ≈ 5.9 Years

Approximately 75% of cars driven by company employees are older than about 5.9 years

Greetings!

The formula for the area of any triangle is as followed:

$A_{triangle}=\frac{bh}{2}$

-------------------------------------------------------------------------------------------------------------

<u>Let Statements:</u>

Let the variable...

→ $b$ represent the length of the base of the triangle

→ $h$ represent the length of the height of the triangle

-------------------------------------------------------------------------------------------------------------

Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:

$10=\frac{(4)(x+3)}{2}$

Distribute the parenthesis<em> (The Distributive Property) </em>:

$10=\frac{((4)(x)+(4)(3))}{2}$

$10=\frac{4x+12}{2}$

Reduce the fraction to lowest terms:

$10=2x+6$

Add -6 to both sides of the equation:

$(10)+(-6)=(2x+6)+(-6)$

$4=2x$

Divide both sides of the equation by 2:

$\frac{4}{2}=\frac{2x}{2}$

$2=x$

-------------------------------------------------------------------------------------------------------------

The Answer to this Problem is:

$\boxed{x=2}$

-------------------------------------------------------------------------------------------------------------

I hope this helped!

12. x + y = 4

Answer:

$x = - \frac{2}{3} \: \: \: y = \frac{14}{3}$

Step-by-step explanation:

Since we know -7x=y we use the substitution method and plug it in the top equation.

$x + - 7x = 4$

$- 6x = 4$

$x = - \frac{4}{6}$

or x=-2/3

Then plug it back in the the bottom equation

$- 7( \frac { - 2}{3} ) = y$

y=14/3
