Answers
Answer:
A, B and D are true.
Step-by-step explanation:
g (x) = x² - 4x + 3
f (x) = x² - 4x
What this means is that;
g (x) = f (x) + 3
What this implies is that the graph of g (x) is equivalent to when we shift that of f function graph up by 3 units.
Since g (x) is essentially shifting of f (x) upwards by 3 units, it means the graphs will never intersect.
It also implies that the vertex of g (x) will be above that of f (x)
Also since it only moves up and not in any other direction, both functions will still have the same line of symmetry.
Thus, options A, B and D are correct

Find the measure of angles?
The equations to find the measure of ∠ ∠ are given. Use the definition of an angle bisector
to find the measure for those two angles.
Answers
Answer:
m<KNL = 65°
m<MNL = 65°
Step-by-step explanation:
An angle bisector divides an angle into two equal parts.
Thus:
m<KNL = m<MNL
Substitute
5x + 10 = 6x - 1
Collect like terms
5x - 6x = -10 - 1
-x = -11
Divide both sides by -1
x = 11
✔️m<KNL = 5x + 10
Plug in the value of x
m<KNL = 5(11) + 10 = 55 + 10
m<KNL = 65°
✔️m<MNL = 6x - 1
Plug in the value of x
m<MNL = 6(11) - 1 = 66 - 1
m<MNL = 65°

Answer:
130.25 ft.
Step-by-step explanation:
The semi circle has a length 1/2 of the circumference of the circle with a diameter of 25
C = πd = 3.14(25)
So, the semi circle has a length = 1/2(3.14)25) = 39.25
The distance for the rectangle = 33 + 25 + 33 = 91
Therefore, the total perimeter = 91 + 39.25 = 130.25

Friedman and Rosenman have suggested that personality type isrelated to heart disease. specifically, type A people, who arecompetitive, driven, pressured and impatient are more prone toheart disease. on the other hand, type B people, who are lesscompetitive and more relaxed are less likely to have heart disease.suppose that an investigator would like to examine the relationshipbetween personality type and disease. for a random sample ofindividuals, personality type is assessed witha standardizedtest. these people are then examined and categorized as to whetherthey have a heart disorder. the observed frequencies are asfollows: noheart disease heartdiseaseTypeA 32 18 50TypeB 128 22 150 160 40is there any relationship between personality and disorder? testat the .05 level of significance.
Answers
Answer:
since p value(0.001091 ) is less than less than alpha(0.05)
null hypothesis H₀ is rejected.
Hence, we conclude that there is a relationship between personality and disorder.
Step-by-step explanation:
Given the data in the question;
non-heart disease heart disease total
TypeA 32 18 50
TypeB 128 22 150
total 160 40
level of significance ∝ = 0.05
H₀ : There is no relationship between personality and disorder
H₁ : There is a relationship between personality and disorder
so
the computational table for x²
E₁ = 50×160 / 200 = 40
O E O-E (O-E)² (O-E)² /E
32 40 -8 64 1.6
18 10 8 64 6.4
128 120 8 64 0.5333
22 30 -8 64 2.133
∑ 10.667
so
X² = ∑( (O-E)² /E ) = 10.667
The contingency table is 2×2, since there are 2 rows and 2 columns
df = (2-1)(2-1) = 1
P Value from Chi-Square Calculator
Chi-square score: 10.667
DF : 1
p-value = 0.001091
since p value(0.001091 ) is less than less than alpha(0.05)
null hypothesis H₀ is rejected.
Hence, we conclude that there is a relationship between personality and disorder.

Which function represents the graph?

The function which represents the graph is : D. y = 3sin(x)
What is function?"A function is an expression which assigns each element of X to exactly one element of Y from a set X to a set Y."
What is the graph of function?"The graph of a function f is the set of all points in the plane of the form (x, f(x))."
What is the graph of sine function?"The graph of y=sin(x) is like a wave that oscillates between -1 and 1, in a shape that repeats itself every 2π units.
Also, the graph of sine function passes though origin, as sin(0) = 0 ."
What is the graph of cosine function?"The graph of y=cos(x) is like the graph of y=sin(x) but shifted horizontally by π units"
From given graph, we can observe that the graph must be of sine function.
Also, given graph represents the graph of y = sin(x) expanded 3 times.
So, the function which represents the graph is, y = 3sin(x).
Hence, the correct answer is option D. y = 3sin(x)

the future value is $5,750.01
Step-by-step explanation:
The computation of the future value is shown below;
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $5,000 × (1 + 0.035 ÷ 12)^4 × 12
= $5,000 × (1 + 0.2916%)^48
= $5,750.01
Hence, the future value is $5,750.01

An experiment was conducted to investigate the effect of management training on the decision-making abilities of supervisors in a large corporation. Sixteen supervisors were selected and eight were randomly chosen to receive managerial training. Four trained and four untrained supervisors were then randomly selected to function in a situation in which a standard problem arose. The other eight supervisors were presented with an emergency situation in which standard procedures could not be used. The response was a management behavior rating for each supervisor as assessed by a rating scheme devised by the experimenter.a. What are the experimental units in this experiment?b. What are the two factors considered in the experiment?c. What are the levels of each factor?d. How many treatments are there in the experiment?e. What type of experimental design has been used?
Answers
Answer:
A) 16 supervisors that were selected.
B) Training and Situation
C) - Trained and untrained
- Standard and Nonstandard
D) 4 treatments
E) Completely randomized block design experiment.
Step-by-step explanation:
A) The experimental units are the subjects upon which the experiment was performed. In this case, that is the 16 supervisors that were selected.
B) The two factors considered were:
- The managerial training
- The situation in which a standard problem arose and also the emergency situation in which standard procedures could not be used.
C) The levels would be the values the experimenter observes as a result of the training and situation.
Thus, the levels are:
- Trained and untrained
- Standard and Nonstandard
D) Number of treatments are the total number of levels gotten in C above.
Thus, number of treatments = 4
E) Since the 16 supervisors that were selected were randomly assigned treatments, we can say it is a completely randomized block design experiment.

Write the slope intercept form of the equation line through given point with given slope .
Answers
Answer:
y =3x + 5
Step-by-step explanation:
The slope intercept form of an equation is expressed as;
y = mx+c
m is the slope
c is the intercept
Get the intercept
Substitute m = 3 and (-2,-1) into y = mx+c
-1 = 3(-2)+c
-1 = -6 + c
c = -1+6
c = 5
Get the equation.
Recall that y = mx+c
y =3x + 5
This gives the required equation
