Answer:
- Let p be the population at t be the number of years since 2011. Then,
- The projected population of the high school in 2015=1800
- In <u>2019</u> the population be 1600 students
Step-by-step explanation:
Given: The population at Bishop High School students in 2011 =2000
Also, Every year the population decreases by 50 students which implies the rate of decrease in population is constant.
So, the function is a linear function.
Let p be the population at t be the number of years since 2011.
Then,
So at t=0, p=2000
In year 2015, t=4, substitute t=4 in the above equation ,we get
Hence, the projected population of the high school in 2015=1800
Now, put p=1600 in the function , we get
Now, 2011+8=2019
Hence, in <u>2019</u> the population be 1600 students
Answer: 5/24
Step-by-step explanation:
7/8 = 21/24 2/3= 16/24
21/24 - 16/24 = 5/24
Find cost of pens and mechanical pencils
pen cost=number of pens times cost pe pen
pencost=10 times 0.35=3.50
mech cost=number of mechs times cost pe mech
mechcost=5 times 0.89=4.45
4.45 is more than 3.50
yes, mech cost mre than pens
Answer:
50%
Step-by-step explanation:
''What is the probability that she selected the biased coin?”
When we have n possible outcomes of an event and all of them have the same probability of appearance, then in theory each possibility has a probability 1/n of being the result of the event.
In this case the event is choosing randomly a coin out of 2, so no matter what the biased coin is or the results we get when we toss it, the probability of choosing the biased coin is ½ = 0.5 or 50%.
