A class of 24 students is planning a field trip to a science museum. A nonrefundable deposit of $50 is required for the day-long

erica [24]

Answer:

Option A , C ,D

Step-by-step explanation:

A nonrefundable deposit required for the day-long program = $50

Charge per person = $4.50

Let us suppose the number of students is s

So, Charge for s students = $4.50s

Let c denotes the total cost

So, total cost : $c=50+4.50s$

So, Option A is correct : The linear model is f(s) = 4.5s + 50.

Total cost : $c=50+4.50s$

We are given that total students are 24

Substitute s = 0

So, $c=50$

Substitute s = 24

$c=50+4.50(24)$

$c=158$

So, Option C and D is also correct.

C. The domain is {x| 0 ≤ x ≤ 24}

D .The range is {y| 50 ≤ y ≤ 158}

Refer the attached figure

The graph is discrete .

So, Option E is incorrect.

According to national data, 5.1% of burglaries are cleared with arrests. A new detective is assigned to six different burglaries

blagie [28]

Answer:

26.95% probability that at least one of them is cleared with an arrest

Step-by-step explanation:

For each burglary, there are only two possible outcomes. Either it is cleared, or it is not. The probability of a burglary being cleared is independent of other burglaries. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

5.1% of burglaries are cleared with arrests.

This means that $p = 0.051$

A new detective is assigned to six different burglaries.

This means that $n = 6$

What is the probability that at least one of them is cleared with an arrest?

Either none are cleared, or at least one is. The sum of the probabilities of these events is 100% = 1. So

$P(X = 0) + P(X \geq 1) = 1$

We want $P(X \geq 1)$

Then

$P(X \geq 1) = 1 - P(X = 0)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{6,0}.(0.051)^{0}.(0.949)^{6} = 0.7305$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.7305 = 0.2695$

26.95% probability that at least one of them is cleared with an arrest

The amount earned in dollars for recycling p pounds of copper is 2p. How much do you earn for recycling 28 pounds of copper

Licemer1 [7]

Answer:

56 dollars are earned for recycling 28 pounds of copper.

Step-by-step explanation:

Quantity of copper recycled = $p$ pounds

Amount earned in dollars for recycling $p$ pounds of copper = $2p$

Also,

Quantity of copper recycled = $28$ pounds

Therefore,

Amount earned in dollars for recycling $28$ pounds of copper = $2(28)=56$ dollars

So,

56 dollars are earned for recycling 28 pounds of copper.

Can someone please answer. There is one problem. There's a picture! Thank you!

Andru [333]

A cotangent (cot) is the adjacent side (not the hypotenuse or side not containing the right angle) over the opposite side, so $cot(G) = \frac{j}{g}$ or the third answer.
