<span>Julia is X+5

</span><span>x+x+5=31
</span>
Now we just solve the equation

2x=31-5
x=26/2
x=13 years old (Babs' age)

and we know that julia is 5 years older this gives us the conclusion that.

13+18=31

Answer:

4.8 years

Step-by-step explanation:

Solving the compound interest formula for the number of years gives ...

t = log(A/P)/(n·log(1 +r/n))

where principal P invested at rate r compounded n times per year produces value A after t years.

t = log(24805/22000)/(365·log(1 +0.025/365)) ≈ 4.800

The loan was for 4.8 years.

guapka [62]

Answer:

d. 11.6

Step-by-step explanation:

The results of the first die and the second one are independent to each other. The expected value of Z is obtained, therefore, by summing the expected values of both X and Y, because Z = X+Y and X and Y are independent. As a result $\mu_z = \mu_x + \mu_y = 3.6+8.0 = 11.6 .$
