5 0

Answer:

Milena was 8 years and 9 months old.

Step-by-step explanation:

11 - 2 = 9

12 divided by 4 = 3

3 x 1 = 3

12 - 3 = 9

Explanation:

Milena would have been 8 years and 9 months old because 2 years before she had just turned 11 she would have just turned 9. And 1/4 a year before she turned 9 she would have been 8 years and 9 months because 1/4 a year equals 3 months.

Leslie decides to join a gym. She must pay a monthly fee plus a one time fee to open a membership. This situation can be modeled
omeli [17]

Step-by-step explanation:

Given function is,

y=55x+80

Where,

y = amount paid to the gym in dollars

x = number of months

So when x = 0, y =55(0)+80 = 80

i.e when number of months is 0, you have to pay a fee of $80.

This is the one time fee to open a membership.

After that for each month you have to pay $55 for each months.

So 55 is multiplied with x.

barxatty [35]

Answer:

The Z score of the person is -3.09.

Step-by-step explanation:

The standard normal deviate (Z) for a normal distribution is given by

Z=\frac{X-\bar{X}}{\sigma }

where,

X = the value of observation

\bar{X} is mean of the observations and

σ = standard deviation of the score

Applying values we get

Z=\frac{59-72}{4.2}=-3.09
