It would be the 2nd answer....your initial value (read from the left of the line graph) is 4.....following the line to the first even point you can see it has dropped 3 for the 4 points it has moved to the right....giving -3/4 as the rate of change.

Chose the equivelent expression for the scenario. phillip mows lawns fro $15 each. if he moves 6 lawn every week for 8 weeks. ho

Ipatiy [6.2K]

Answer:

15 x 6 x 8

Step-by-step explanation:

total money is cost per lawn times number of lawns per week times number of weeks

cost per lawn is $15

number of lawns per week is 6

number of weeks is 8

so cost total money is 15 x 6 x 8 which is none of them

Let X denote the time from the present until the stock market hits 25,000. If X ≤ 1, you win $10, 000X. If X > 1, you win not

Answer: $6321

Step-by-step explanation:

Expected value is given as exactly what you might think it means intuitively, the return you can expect for some type of action.

The basic expected value formula is the probability of an event multiplied by the amount of times the event happens:(P(x) * n).

he formula for the Expected Value for a binomial random variable is:

P(x) * X.

X is the number of trials and P(x) is the probability of success.

The formula for calculating the Expected Value where there are multiple probabilities is:

E(X) = ∑X * P(X)

The equation is basically the same, but here you are adding the sum of all the gains multiplied by their individual probabilities instead of just one probability.

Calculating the expected value of winning as follows:

Given,

Fx= e^-x, x is greater or equal to 0

Now, P less than or equal to zero =

[-e^-x] ^1

e^-0 - e^-1

= 1 - e^-1

= 0.6321

and P(x>1) = 1-0.6321= 0.3679

Therefore,Let y= amount of winnings.

Based on the above given information,

y= $10000 0

P(y)= 0.6321 0.3679

The expected value of winning:

E(y) = ΣyP(y)

E(y) = 10000 × 0.6321 + 0 × 0.3679

E(y) = $6321

Therefore, the expected value of winning is $6321

Using the given functions, it is found that:

Lower total cost at Jump-n-Play: 40, 64.

Lower total cost at Bounce house: 28, 8, 30.

Same total cost at both locations: 32.

<h3>What are the cost functions?</h3>

For n visits to Jump-n-play, the cost is:

J(n) = 189 + 3n.

For n visits to Bounce Word, the cost is:

B(n) = 125 + 5n.

Comparing them, we have that:

$J(n) < B(n)$

$189 + 3n < 125 + 5n$

$64 < 2n$

$n > 32$

Hence:

For less than 32 visits, the cost at Bounce World is lower.

For more than 32 visits, the cost at Jump-n-play is lower.

Hence:

Lower total cost at Jump-n-Play: 40, 64.

Lower total cost at Bounce house: 28, 8, 30.

Same total cost at both locations: 32.
