I think your asking how much the school will have left over. If so:

125 ( not including the tickets)
It depends on how many kids are coming to the dance in order to fully solve this problem.

You didn't word this properly so that what I got with what I had:)

If you have anymore questions, ask me them on my profile so I'll be sure to get them:)

I hope this helps:)

Part A

Answer:

A. $f(n) =0.2n+4.8$

B. The y intercept is 4.8

Step-by-step explanation:

Given

$a_n= 5 + 0.2(n-1)$

Solving (a): Write as a function.

To do this, we simply substitute f(n) for $a_n$

$a_n= 5 + 0.2(n-1)$ becomes

$f(n)= 5 + 0.2(n-1)$

Open Bracket

$f(n) = 5 + 0.2n-0.2$

Collect Like Terms

$f(n) =0.2n-0.2 + 5$

$f(n) =0.2n+4.8$

B. The y intercept.

To get the y intercept, we set n to 0

i.e

$f(0) =0.2 * 0+4.8$

$f(0) =0+4.8$

$f(0) =4.8$

Hence, the y intercept is 4.8

Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal

frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

We define as success to: missing metal carrying detection.

p=0.01

P(x)= $\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}$

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)= $1 - 0.99^{50}$ =0.395

Evaluate the function f (x)  4 • 7x for x  1 and x = 2. Show your work

SashulF [63]

The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function $f(x)=4.7^x$ for x = - 1 and x 2.

The solution is:

1) For x = - 1

$f(-1)=4. 7^{-1} =4. (1/7)=4/7$

2) For x = 2

$f(2)=4.7^2=4(49)=196$

after sharing a pizza you and two friends divide the cost by three. You each owe $2.66. Explain how to round this to the nearest

Stolb23 [73]

Answer:

Hi so you have the answer

Say you have 1.23 if the last digit is under 5 it would be 1.20

Now say you have 3.47 if the last digit is above 5 it would be 3.50

If it is something like 4.45 the 5 is the last digit so it would be 4.50

Step-by-step explanation:

um hope this helped :)
