The area under the given curve is 77/60. SO the option B is correct.
In the given question we have to estimate the area under the curve given the following fuction, interval, and number of subintervals using the right endpoint method.
The given function is
F(x) = 1/x; [1,5]; n=4
The given options are:
A≈77/240
A≈77/60
A≈77/15
A≈25/3
A≈25/12
Since, f(x) =1/x
∆x = (b-a)/n
∆x = (5-1)/4
∆x =4/4
∆x = 1
Now the table is
x 1 2 3 4 5
f(x) 1 1/2 1/3 1/4 1/5
R(4) = [f(2)+f(3)+f(4)+f(5)]∆x
R(4) = [1/2+1/3+1/4+1/5]1
R(4) = (30+20+15+12)/60
R(4) = 77/60
Hence, the area under the given curve is 77/60. SO the option B is correct.

1) The probabilities are given as follows:
a) More than 75: 0.0301 = 3.01%.
b) Between 60 and 73: 0.4484 = 44.84%.
c) Less than 50: 0.1057 = 10.57%.
2) The proportion of students who fail the module is of: 0.0062 = 0.62%.
3) The measures are given as follows:
Mode: 60.Median: 60.Variance: 64.How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation in this problem are given as follows:
[tex]\mu = 60, \sigma = 8[/tex]
The probability that an score is more then 75 is one subtracted by the p-value of Z when X = 75, hence:
Z = (75 - 60)/8
Z = 1.88
Z = 1.88 has a p-value of 0.9699.
1 - 0.9699 = 0.0301 = 3.01%.
The probability of an score between 60 and 73 is the p-valeu of Z when X = 73 subtracted by the p-value of Z when X = 60, hence:
Z = (73 - 60)/8
Z = 1.63
Z = 1.63 has a p-value of 0.9484.
Z = (60 - 60)/8
Z = 0
Z = 0 has a p-value of 0.5.
Then:
0.9484 - 0.5 = 0.4484 = 44.84%.
The probability of an score less than 50 is the p-value of Z when X = 50, hence:
Z = (50 - 60)/8
Z = -1.25
Z = -1.25 has a p-value of 0.1057.
The proportion who might fail the test is the p-value of Z when X = 40, hence:
Z = (40 - 60)/8
Z = -2.5
Z = -2.5 has a p-value of 0.0062.
Then the statistical measures are obtained as follows:
Mode: 60. -> equals to mean.Median: 60. -> equals to mean.Variance: 64. -> standard deviation squared.More can be learned about the normal distribution at https://brainly.com/question/25800303

The measure of the angle ∠BDC is 68°.
What is the straight line angle?
A straight angle in geometry is one that is 180 degrees in length. It looks like a straight line, which is why it is known as a straight angle. In other words, it is an angle whose sides are in the same straight line but opposite to the vertex.
We have,
∠BDA is a straight angle
so ∠BDA = 180°
We need to find the ∠BDC
∠CDA = -8x + 48°
∠BDC = -7x + 12°
∠BDA = ∠BDC + ∠CDA = 180°
(-8x + 48°) + (-7x + 12°) = 180°
-15x + 60° = 180°
-15x = 120°
x = -8°
∠BDC = -7x + 12°
= -7(-8°) + 12°
= 56° + 12°
= 68°
Hence, the measure of the angle ∠BDC is 68°.

Macaroni penguins weigh 5 1/2 kg when they are adults when they are born they weigh 150 g. In grams how much weight do they gain from check to adult?
Using the conversion factor we know that the penguin gained 5,350 grams of weight from a chick to an adult.
What is the conversion factor?A conversion factor is a quantity or formula required to change a measurement from one system of units to another system of the same measurement.
The amount is often expressed as a fraction or ratio with a multiplication factor.
A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).
So, we know that:
1 kg = 100 g
Weight of the adult penguin: 5 1/2 kg that is,
5 1/2 = 10+1/2 = 11/2 = 5.5
5.5kg = 5500 g
Weight of the newborn penguin: 150 g
Weight gain from chick to adult:
5500 - 150
5,350 g
Therefore, using the conversion factor we know that the penguin gained 5,350 grams of weight from a chick to an adult.

explain why the solution of 5x minus 3 is greater than 14.5 or 2x plus 5 divided by 3 is less than 4 has a solution of all the real numbers, with one exception
From the compound inequality explained below in concept, it has been proven that compound inequality has a solution of all real numbers except 3.5.
How to solve Inequality problems?
We are given the inequalities as;
5x – 3 > 14.5 or (2x + 5)/3 < 4
For the first inequality;
Add 3 to both sides to get;
5x > 17.5
Divide both sides by 5 to get;
x > 3.5
For the second inequality, we have;
(2x + 5)/3 < 4
Multiply both sides by 3 to get;
2x + 5 < 12
Subtract 5 from both sides to get;
2x < 7
Divide both sides by 2 to get;
x < 3.5
The first inequality gives the solution as x > 3.5.
The second inequality gives the solution as x < 3.5.
The solution of an “or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

Although part of your question is missing, you might be referring to this full question: If P is the incenter of ΔJKL, find each measure (triangle as attached).
Based on the property of incenter, the measurements of the sides and the angles will be:
JK = 21.2 units
KL = 26.63 units
JL = 28.33 units
m∠K = 36°
By using the property of incenter:
PM = PN = PO = 7 units
∠MJP = ∠OJP = 32°
∠NLP = ∠OLP = 22°
By using the triangle sum theorem,
m∠JKL + m∠KLJ + m∠LJK = 180°
2(m∠NKP) + 2(m∠NLP) + 2(m∠MJP) = 180°
2(m∠NKP) + 2(22°) + 2(32°) = 180°
2(m∠NKP) = 180° - 108°
m∠NKP = 36°
Then, from ΔJMP,
tan(32°) = MP/MJ
tan(32°) = 7/MJ
MJ = 7/tan(32)°
MJ = 11.20
And from ΔPOL,
tan(22°) = OP/OL
tan(22°) = 7/OL
OL = 17.33
And from ΔKNP,
tan(36°) = NP/KN
tan(36°) = 7/KN

Calculating Unknown Quantity:To find an unknown quantity in a problem we use the algebraic expression. These are combinations of variables and constant terms. Here variables are used to represent the Unknown Numbers.
Here we have
Martina, Ahmad, and Ryan served a total of 87 orders
Since we don't how many orders served each one
Let's assume that each of them with different variables
Martina served 'm' orders
Ahmad served 'a' orders
Ryan served 'r'
Given that
Ahmad served 9 fewer orders than Martina
=> a = m - 9 ---- (1)
Ryan served 2 times as many orders as Martina.
=> r = 2m --- (1)
Given that total served orders = 87
=> m + a + r = 87
=> m + m - 9 + 2m = 87 [ from (1) and (2) ]
=> 4m = 87 + 9
=> 4m = 96
=> m = 24
Number of orders served by Ahmad, a = 24 - 9 = 15
Number of orders served by Ryan, r = 2(24) = 48

In her random sample, the sample mean is y¯ = 3.15 kg and the standard deviation is 250 grams. (a) Calculate a 95% confidence interval for the population mean birth weight in these hospitals. (b) The typical weight of a baby at birth for the US population is 3.25 kg. The investigator suspects that the birth weights of babies in these teaching hospitals is different than 3.25 grams, but she is not sure if it is smaller (from malnutrition) or larger (because of obesity prevalence in mothers giving birth at these hospitals). Carry out the hypothesis test that she would conduct.
a)95% confidence interval for the population mean birth weight in these hospitals is (3078.9358,3221.0642).
(b)The P-value is 0.0068.
What is hypothesis testing?To test the null hypothesis and the alternative hypothesis, all analysts employ a random population sample. The null hypothesis typically states that two population parameters are identical; for instance, it can claim that the population mean return is equal to zero.
Why is hypothesis testing used?A strategy for determining how reliably one may extrapolate observed results in a study sample to the larger population from is provided by hypothesis testing, a procedure used to assess the strength of the evidence from the sample and give a framework for doing so.

if I make you a pie then eat 2 slices of pie and make two more slices of pie for another pie how many missing slices of pie would the first pie be missing
If you made a pie and then ate two slices of it, the first pie would be missing two slices of pie. If you then made two more slices of pie for another pie, the first pie would be missing a total of four slices of pie. This is because you took two slices of pie from the first pie and added them to the second pie, leaving the first pie with two fewer slices than it originally had.
Answer:
The first pie would be missing four slices in total
Step-by-step explanation:
If you make a pie and then eat two slices of it, there would be two missing slices from the first pie. If you then make two more slices of pie for another pie, the first pie would be missing a total of four slices. The first pie would be missing four slices in total.

Define Scatter plot.An example of a plot or mathematical diagram is a scatter plot, which uses Cartesian coordinates to show the values of typically two variables given a collection of data. One more variable can be presented if the points are programmed.
Here,
The observed data are highly erratic, according to scatter plot 1. The relationship between the two variables is thus weak. There is a 0.342 correlation coefficient.
Observations in the scatter plot 2 are aligned with the straight line. A reduction in y values follows a rise in x values. Therefore, there is a significant negative connection between the two variables. This means that the correlation coefficient is -0.994.
The scatter plot's third scatter plot shows that the observations are slightly yet positively divergent. Consequently, there is a weakly positive connection between the two variables. The correlation coefficient is therefore 0.743.
Scatter plot 4: The observations show a considerably negative deviation from the mean. Consequently, there is a light negative correlation between the two variables. Consequently, the correlational coefficient is -0.743.
Scatter plot 5: The observations are aligned with the straight line in the scatter plot. The matching y values rise as the corresponding x values do. Therefore, there is a significant positive connection between the two variables. So, 0.994 is the correlation coefficient. As follows is the matching table:
