The lassos high school senior class raised funds for an end of the year cruise getaway. The city gave them a special package for

kirill115 [55]

Answer:

Step-by-step explanation:

x = total number of students

1500 + 367x = 16,600

367x = 16,600 - 1500

367x = 15100

x = 15100 / 367

x = 41.14.......rounds to 41 students <==

this only works if the port fees and taxes that the city gave them are included in the money the class raised

Mark got 14 problems wrong on his test. His score was 72% correct. How many problems were on the test? Please show work.

stira [4]

Consider that 100%-72%=28% represents the percentage of wrong answers. I would think as fractions as:
if 100% is the total number of answers and 28% are the wrong ones
as
if x is the total you have 14 wrong you can write:
$\frac{100}{28} = \frac{x}{14}$
x=(100/28)*14=50 questions

The university police department keeps track of the number of tickets it write in a year. Last year the campus police wrote 1460

AlladinOne [14]

Answer:

2

Step-by-step explanation:

We are given that Ticket writing on campus follows a Poisson process.

Last year the campus police wrote 1460 tickets

So, $X \sim Poisson (1460 / year)$

1 year = 365 days

So, E(Y) = $\frac{1460}{365}=4$

So, the standard deviation of the number of tickets written per day by the campus police = $\sqrt{4} =2$

Hence the standard deviation of the number of tickets written per day by the campus police is 2

Can someone help me please

pychu [463]

Mr Green: $4(3a+1+2b) = 12a + 4 + 8b$

Mrs Green: $6(5a-a)+4(2+4b)=6*4a + 8 + 16b = 24a +16b + 8$

Keith: $4(2+4b+6a) = 8 + 16b + 24a=24a+16b + 8$

Kevin: $4(6a+2)+8b + 2 = 24a + 8 + 8b + 2 = 24a + 8b + 10$

Thus Mrs Green and Keith has the expression that is equivalent to

'24a + 16b + 8'

Hope that helps!
