The probability that Jessica is on time for a given class is 64 percent. If there are 53 classes during the semester, what is the best estimate of the number of times out of 53 that Jessica is on time to class? Round your answer to the nearest integer.
Provide your answer below:

Answers

Using the principle of probability, the estimated number of times Jessica will be on time is 34.

Given the Parameters :

Probability of being on time, p = 64% = 0.64

Total number of classes, n = 53

The best estimate for the number of times Jessica will be on time can be calculated thus :

Mean = np

Hence, we have ;

Mean number of times = (0.64 × 53)

Mean number of times = 33.92

Hence, the estimated number of times Jessica will be on time is 34.

Lila evaluates the expression using the following steps:(−7.13+63.97)+(−54.8−3.4)−71.1+(−58.2)−129.3Describe the error that Lila made.

Answers

Lila's error was that she added -7.13 to 63.97 to get -71.1

Lila steps are as folows

(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3

In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.

So, the correct expression should be

(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36

So, Lila's error was that she added -7.13 to 63.97 to get -71.1

One method of slowing the growth of an insect population without using pesticides is to introduce into the population a number of sterile males that mate with fertile females but produce no offspring. If P represents the number of female insects in a population, S the number of sterile males introduced each generation, and r the population's natural growth rate, then the female population is related to time t by
t =
P+S
P[(r−1)P − S]
dP

Suppose an insect population with 10,000 females grows at a rate of r = 0.10 and 900 sterile males are added in each generation. Evaluate the integral to give an equation relating the female population to time. (Note that the resulting equation cannot be solved explicitly for P.)

Answers

t = integral [(P+S)/P((r-1)P-S)] dP

now, to do partial fraction decomposition, consider

(P+S)/P((r-1)P-S) = A/P + B/((r-1)P-S)

P + S = A((r-1)P -S) + PB

if P = 0, then:

A = -1

If (r-1)P - S = 0

=> p = S/(r-1)

B = 1 + r - 1

B = r

Therefore

t = integral(-1/P + (r-1+1)/((r-1)P - S))dP

t = -ln|P| + ln|(r-1)P-S| + 1/r-1 * integral((r-1)/[(r-1)P-S])

t = -ln|P| + ln|(r-1)P-S| + ln|(r-1)P-S|/(r-1)

t = -ln|P| + (r/r-1)ln|(r-1)P-S|

substituting known constants, we get:

t = -ln|P|-1/9(ln|-0.9P - 900|)

t = -ln|P| - 1/9(ln|-0.9P -900|)

t = -ln|P| - 1/9(ln(|(-9/10)(P + 1000)|))

t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

as P >= 0, ln(P) and ln(P + 1000) doesn’t need abs value

Note that our expression for t doesn’t account for P=0 as ln(P) is undefined at P = 0.

The expression for t is also undefined at P = -1000, but that falls outside our domain P >= 0, so we don’t really need to worry about that.

The equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that the female population is related to time t by;

[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]

Now, to do partial fraction;

(P+S)/P((r-1)P-S) = A/P + B/((r-1)P-S)

P + S = A((r-1)P -S) + PB

if P = 0, then:

A = -1

If (r-1)P - S = 0

p = S/(r-1)

B = 1 + r - 1

B = r

Therefore,

[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]

t = -ln|P| + ln|(r-1)P-S| + 1/r-1 x integral((r-1)/[(r-1)P-S])

t = -ln|P| + ln|(r-1)P-S| + ln|(r-1)P-S|/(r-1)

t = -ln|P| + (r/r-1)ln|(r-1)P-S|

Now substituting known constants then;

t = -ln|P|-1/9(ln|-0.9P - 900|)

t = -ln|P| - 1/9(ln|-0.9P -900|)

t = -ln|P| - 1/9(ln(|(-9/10)(P + 1000)|))

t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

as P >= 0, ln(P) and ln(P + 1000) doesn’t need abs value

Therefore, the equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

Answers

9514 1404 393

Answer:

  1. a linear model

  3. y = 24.97x +417.59

  4. 75 workers

Step-by-step explanation:

1. A graph of the data seems to show it nearly follows a straight line. We have used a linear function to model the data.

3. The linear regression model is ...

  y = 24.97x +417.59

4. The graphing calculator shows the point (x, y) ≈ (75.4, 2300) is on the line of best fit. Marco should recommend 75 workers for production of 2300 units per hour.

If you want to solve the linear equation ...

  2300 = 24.97x +417.59

you get ...

  x = (2300 -417.59)/24.97 ≈ 75.4

About 75 workers are needed.

Monday evening, the jar of M & M's© is full. Tuesday, 1 8 of the M & M's are eaten. Wednesday, 1 3 of the M & M's that remained disappeared. Thursday morning, first thing, the jar had 42 M & M's remaining. How many M & M's were in the jar on Monday evening? M & M's

Answers

9514 1404 393

Answer:

  72 M&Ms

Step-by-step explanation:

We understand the problem to say ...

Monday the jar was fullTuesday the jar was 7/8 full (1/8 gone)Wednesday, the jar was (7/8)(2/3) = 7/12 full

That 7/12 full condition corresponds to 42 M&Ms being present.

  42 = 7/12·full

  full = 42(12/7) = 72

There were 72 M&Ms in the jar on Monday evening.

_____

Check

1/8 of 72 = 9 were eaten Tuesday

1/3 of the remaining 63 disappeared on Wednesday. That number is 21, so 63-21 = 42 remained after Wednesday. That is the number seen early Thursday.

There were 72 M & M's in the jar on Monday evening

How to determine the number of M & M's?

Let the initial number be x.

When 1/8 of the M & M were eaten on Tuesday, the remaining proportion is:

Remaining = (1 - 1/8) * x

This gives

Remaining = 7x/8

When 1/3 of the M & M disappeared on Wednesday, the remaining proportion is:

Remaining = (1 - 1/3) * 7x/8

This gives

Remaining = 7x/12

On Thursday, the remaining number of M & M is 42.

This means that:

7x/12 = 42

Divide both sides by 7

x/12 = 6

Multiply both sides by 6

x = 72

Hence, there were 72 M & M's in the jar on Monday evening
