The Schuller family has five members. Dad is 6ft 2in tall. Mom is 3 inches shorter than Dad, but 2 inches taller than Ivan. Marc

ohaa [14]

Answer:

62 inches

Step-by-step explanation:

Let x be the height ( in inches ) of Ivan,

∵ Marcia is 5 inches shorter than Ivan,

height of Marcia = x - 5,

Marcia is twice as tall as Sally-Jo,

height of sally-jo = $\frac{x-5}{2}$

Mom is 2 inches taller than Ivan.

⇒ height of mom = x + 2,

Mom is 3 inches shorter than Dad,

height of dad = x + 2 + 3 = x + 5,

So, mean height of family is,

$\frac{x+x-5+\frac{x-5}{2}+x+2+x+5}{5}$

$=\frac{2x+2x-10+x-5+2x+4+2x+10}{10}$

$=\frac{9x-1}{10}$

According to the question,

x + 5 = 74 ( 1 ft = 12 in )

x = 69

Hence, mean height of the family = $\frac{9\times 69-1}{10}$

$=\frac{620}{10}$

= 62 inches

You have conducted pre- and post-test measures of the effectiveness of pay raises on employee productivity, measured as net $ sa

lord [1]

Answer:

2000 USD

Step-by-step explanation:

a. Difference for employee 1: 14000 - 10000 = 4000

b. Difference for employee 2: 11000 - 12000 = -1000

c. Difference for employee 3: 13000 - 11000 = 2000

d. Difference for employee 4: 10000 - 8000 = 2000

e. Difference for employee 5: 12000 - 9000 = 3000

The absolute mean difference of 5 employees is

(4000 - 1000 + 2000 + 2000 + 3000)/5 = 10000/5 = 2000

So the average net increase of each employed in the past month is 2000 USD

It took Max 3.5 hours to cover a certain route walking at a rate of 2.4 mph. How long would it take Max to cover the same route

andrew11 [14]

It would take 2.8 hours ((3.5 hours x 2.4 Mph)/3Mph) hours for Max to cover the same route walking 3 mph. This problem can be solved by using the velocity equation which is the velocity is equal a change in position divided by a change of time. The amount of time can be found assuming that Max walks in a constant velocity from the starting point until the finish point of 8.4 miles distance (3.5 hours x 2.4 mph)<span>.</span>

What are the domain and range of the function f(x) = 3^x + 5

Sati [7]

The range is y values and domain is x values

y intercept here is 5 and since the function is increasing thus the range would be all real values bigger than or equal to 5

And the domain would be all real numbers.
