The data that were collected are displayed in the scatterplot and the least-squares regression line was calculated. One student with 2 absences has a gpa of 1. 8. This point is circled on the graph. What effect does the circled point have on the slope and y-intercept of the least-squares regression line? this point will increase the value of the slope and increase the value of the y-intercept. This point will increase the value of the slope and decrease the value of the y-intercept. This point will decrease the value of the slope and increase the value of the y-intercept. This point will decrease the value of the slope and decrease the value of the y-intercept.
Based on the information given, the effect of the circled point on the correlation will be D. This point will decrease the value of the slope and decrease the value of the y-intercept.
What is correlation?From the complete information, it can be noted that the effect of the circled point on the correlation is that the correlation will be weakened because the point falls outside the data pattern.

The security system in a house has two units that set off an alarm when motion is detected. Neither one is entirely reliable, but one or both always go off when there is motion anywhere in the house. Suppose that for motion in a certain location, the probability that detector a goes off and detector b does not go off is 0. 25, and the probability that detector a does not go off is 0. 35. What is the probability that detector b goes off?.
The probability that detector B goes off is 0.75
The probability of an event is known to be the likelihood or chance for an event to occur.
From the given information let consider:
A = the time when detector A goes off, andB = the time when detector B goes offSince one or both of them always goes off, then:
P(A or B) = 1∴
Their complements will be zero, i.e.
P(A' and B') = 0Similarly, we are given that:
P(A and B') = 0.25Then;
P(A') = 0.35∴
The set probability for A will be:
P(A) = 1 - P(A')
P(A) = 1 - 0.35
P(A) = 0.65
Finally, the probability that detector B goes off can be computed as:
P(B) = P(A) P(B|A) +P(A') P(B|A')
P(B) = P(A) (1 - P(B|A')) + P(A') (1 - P(B'|A')
[tex]\mathbf{P(B) = P(A) (1-\dfrac{P(A \ and \ B')}{P(A)}) +P(A') (1 - \dfrac{P(A' \ and B')}{P(A')})}[/tex]
[tex]\mathbf{P(B) = 0.65 (1-\dfrac{0.25}{0.65}) +0.35 (1 - \dfrac{0}{0.35})}[/tex]
P(B) = 0.75

The barry family invited 100 relatives to their christmas party. 90 guests had italian heritage, 80 had german heritage and 75 had swiss heritage. What is the minimum number of people who claimed ancestry from all three heritages?.
Answer:
45
Explanation:
The minimum number of people who claimed ancestry from all three heritages is : 45
Given that there are 100 relatives
let's assume that 1 relative = 1 room
100 relatives = 100 rooms
Number of relatives with Italian heritage = 90
Number of relatives with German heritage = 80
Number of relatives with swiss heritage = 75
Step 1 :
Fill up the first 90 rooms with Italian heritage relatives
Fill up the remaining 10 rooms with 10 Relatives with German heritage
Step 2 :
Distribute the remaining 70 relatives with German heritage into 70 rooms out of the 90 rooms already occupied by the relatives with Italian heritage
Step 3:
Distribute the 75 relatives with swiss heritage into the 20 rooms occupied by Italian heritage relatives only and 45 rooms occupied by both German and Italian relatives and into the 10 rooms occupied by the German heritage relatives
Therefore we can conclude that the minimum number of people who claimed ancestry from all three heritages is : 45

The life span of a battery is the amount of time the battery will last. The distribution of life span for a certain type of battery is approximately normal with mean 2. 5 hours and standard deviation 0. 25 hour. Suppose one battery will be selected at random. Which of the following is closest to the probability that the selected battery will have a life span of at most 2. 1 hours?.
The probability that the selected battery will have a life span of at most 2.1 hours is 5.48%.
z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x\ is\ raw\ score, \mu\ is\ mean,\sigma\ is\ standard \ deviation[/tex]
Given that μ = 2.5, σ = 0.25.
For x < 2.1:
[tex]z=\frac{2.1-2.5}{0.25}=-1.6[/tex]
From the normal distribution table, P(x ≤ 2.1) = P(z < -1.6) = 0.0548 = 5.48%

A student places a set of books with a force of 25 n on a lab table with a force of 150 n. What is the normal force pushing upward on the legs of the table?.
The normal force acting on the legs of the table is 175 N
The weight of the books is the force exerted by the books on the table, and it is given as:
[tex]W =25N[/tex]
The force exerted by the table is given as:
[tex]F = 150N[/tex]
The parameters above imply that:
The table and the books are stationary,The force exerted by both act in the same downward direction.So, the normal force acting on the legs of the table is calculated as follows:
[tex]F_N =F +W[/tex]
Substitute known values
[tex]F_N = 150N + 25N[/tex]
[tex]F_N = 175N[/tex]

If x = 23 is a critical point of g(x), then
[tex]g'(x) = 2x e^{kx} + kx^2 e^{kx} = (kx^2 + 2x) e^{kx}[/tex]
[tex]\implies g'(23) = (23^2k + 46) e^{23k} = 0[/tex]

What is Theory of Evolution?Those who are more physically capable of surviving, maturing, and reproducing. On the other hand, those who lack this fitness either do not live long enough to reproduce or have fewer children than their counterparts.
Because the "fittest" organisms—those most adapted to their environment—are the ones that reproduce most successfully and are most likely to pass on their qualities to the next generation, natural selection is sometimes summed up as "survival of the fittest."
This means that if an environment changes, qualities that help people survive in it will eventually adapt, or develop. Natural selection was a potent force.
