A novelist can write 1 chapter in 6 days. At that rate how many chapters can be written in 24 days

2 answers:

6 0

Think: "1 chapter in 6 days." Now if we consider 24 days (which is 4 times 6 days), then the number of chapters that can be written in 24 days is 4.

Alternatively, set up and solve an equation of ratios:

1 6 days

-- = -------------

x 24 days

This yields x = 4; 4 chapters can be written in 24 days.

I think that the answer would be 4 chapters.

Sorry if I'm wrong!

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

TEA [102]

Answer: total amount of money in commission that the realtor earned is $9375

Step-by-step explanation:

The realtor earns 1.25% commission on the price of any home she sells.

Last month she sold two homes for a total of $750,000

It means that the amount of money in commission that the realtor earned last month would be

1.25/100 × 750 000 = 0.0125 × 750000 = $9375

The table below shows the velocity y, in miles per minute, of a toy car at different times x, in minutes: Time (x) (minutes) 10

MrMuchimi

A. If you plot the points in a graph, it would look like that shown in the picture attached. If we use linear regression, the correlation is very poor. The coefficient of correlation (r2) is only 0.0017. There is no linear relationship between time and velocity.

B. The slope of the graph is equal to y2-y1/x2-x1, In this case, it would specifically be v2-v1/t2-t1

Slope = 0.8-0.2/20-10 = 0.06 miles/s^2

The slope represents the acceleration at time 10 to 20 minutes.

C. The table in the graph shows causation rather than correlation. The points in the data occur in a sequential manner.
