Answer:

Expected number of students would have a driver's license = 6

Step-by-step explanation:

Explanation:-

Given data In a class of 25 students, 15 of them have a driver's license

The sample proportion

$p = \frac{x}{n} = \frac{15}{25} = 0.6$

Let 'X' be the binomial distribution

Given sample size 'n' = 10

mean of the binomial distribution or expected number of students would have a driver's license

μ = n p

= 10 × 0.6

= 6

Conclusion:-

Expected number of students would have a driver's license = 6

Answer:

$y = 1500 * 1.09^t$

Step-by-step explanation:

$\text{It should be clear that the rate of change is non-linear}$ $\text{, meaning that we can express the function in the following manner}$

$\text{y = a * b^t, where a is the initial value and b is the rate of change and t is how}$ $y = a * b^t,$ $\text{where a is the initial value and b is the rate of change and t is how many years.}$

$\text{Well, year 0 is the rate of change so we can say that a = 1500}$

$\text{Next, we divide any two consecutive year balances to find our rate of change:}$

$1635/1500 = 1.09$

$\text{Therefore, our equation looks like this:}$

$y = 1500 * 1.09^t$

Step-by-step explanation:

Step 1: Define

-6(t + 2) = 18

Step 2: Solve for t

[Distributive Property] Distribute -6: -6t - 12 = 18
[Addition Property of Equality] Add 12 on both sides: -6t = 30
[Division Property of Equality] Divide -6 on both sides: t = -5
