To solve for h
8h +16h equals 24 h
24h-12= 24h-12
these are equal so no !after what number you put in for h it will be a true statement. in situations like these my math teacher told me to put "all sol."

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

Hey

Ray Of Light [21]

To find the first blank, just replace x in the equation with 12 and solve.
a(12) = 50 - 1.25(12) = your answer for blank 1

For blank 2: because x represents the number of apps on her phone, and x is given 12 for this problem, she bought 12 apps.

For blank 3: You would mention how many apps she got twice, so not the first option or the third option. It should be the answer from the first blank because the equation represents how much money is in her account.
