B. The pattern shows the points are far from the zero line, indicating a good fit for a linear model.
C. The pattern is random, indicating a good fit for a linear model.
D. The pattern shows the points are far from the zero line, indicating a good fit for a nonlinear model.
E. The pattern is random, indicating that the model is unable to be determined.
Answers
Answer:
The correct option is;
C. The pattern is random, indicating a good fit for a linear model
Step-by-step explanation:
A graph that has the residuals (the difference between the value observed and the value expected (regression analysis) on the vertical axis and the variable that is not affected by the other variables (independent variable) on the x or horizontal axis is known as a residual plot
A linear regression model is suited in a situation where the points are dispersed randomly on both sides of the horizontal axis
Therefore, given that the first point is below the horizontal axis and the next point is above the horizontal axis, while the third and the fourth points are below the horizontal axis, the fifth, sixth, and seventh points are above the horizontal axis and the eighth point is below the horizontal axis, the points are random around the horizontal axis, indicating the suitability of a linear regression model.
Answer:
C. The pattern is random, indicating a good fit for a linear model.

What is a polynomial?Polynomials are those algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.
Polynomials are expressions involving variables raised with non negative integers and coefficients (constants who are in multiplication with those variables) and the constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.

Answers
Answer:
Step-by-step explanation:
Given
<LON = 77°
<LOM = (9x+44)°
<MON = (6x+3)°
The addition postulate is true for the given angles since tey have a common point O:
<LON = <LOM+<MON
Since we are not told what to find we can as well look for the value of x, <LOM and <MON
Substitute the given parameters and get x
77 = 9x+44+6x+3
77 = 15x+47
77-47 = 15x
30 = 15x
x = 30/15
x = 2
Get <LOM:
<LOM = 9x+44
<LOM = 9(2)+44
<LOM = 18+44
<LOM = 62°
Get <MON:
<MON = 6x+3
<MON = 6(2)+3
<MON = 12+3
<MON = 15°

DMC Inc. Is planning to issue a $1,000 face value bond with an annual coupon rate of 10% that matures in 20 years. DMC is planning to pay semiannual interest payments. Similar DMC bonds are quoting at 95% of par. What is yield to maturity for this bond?
Answers
Answer: 10.6%
Step-by-step explanation:
Given the following :
Face value (FV) = $1000
Coupon rate (C) = 10% paid semianually
Time to maturity = 20 years ; number of periods =( 20 * 2) = 40 (Semi-annual)
Current trading price of bond = 95% * 1000 = $950
Payment per period = (10%) / 2 * 1000 = 0.05 * 1000 = 50
Inputting the parameters above into the the yield to maturity calculator with semiannual payment,
Yield to maturity (YTM) = 10.6%

It is estimated that the distance traveled by each volunteer driver at the Huntington VA Medical Center is normally distributed with a mean of 50 thousand miles and a standard deviation of 12 thousand miles each year. What percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year?
Answers
Answer: 25.08%
Step-by-step explanation:
Given: Distance traveled by each volunteer driver is normally distributed.
Mean ([tex]\mu[/tex]) = 50 thousand miles
standard deviation ([tex]\sigma[/tex])= 12 thousand miles
Let X = distance traveled by each volunteer driver
Required probability : [tex]P(X<30)+P(X>60)[/tex]
[tex]=P(\dfrac{X-\mu}{\sigma}<\dfrac{30-50}{12})+P(\dfrac{X-\mu}{\sigma}>\dfrac{60-50}{12})\\\\=P(z<-1.67)+P(z>0.83)\ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\= (1-P(z<1.67))+(1-P(z<0.83)\ \ \ [P(Z<-z)=1-P(Z<z)=P(Z>z)]\\\\= 2- P(z<1.67)-P(z<0.83)\\\\= 2- 0.9525-0.7967=0.2508\ \ [\text{By p-value table}][/tex]
Hence, percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year = 25.08%

The lines are parallel
Step-by-step explanation:
The slopes are the same
The equations are both written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-3/5 is the slope in both equations
When the slopes are the same the equations are parallel
They have different y intercepts, so they are different lines ( if they have the same y intercept and same slope, they would be the same line)
Franco begins to save for a new Lego set that costs $65. His parents gave him $35 towards the cost
and he plans to save $5 per week. Define all unknown variables. Write an equation modeling the total
amount he has saved.
Answers
Answer:
65-35=30
30 divided by 5 = 6
Step-by-step explanation:
First you have to subtract 65-35, which equals 30.
Then the problem says he plans to save 5 each week. That means he should get his lego set in 6 weeks, because 30 divided by 5 = 6
65-35=30
30 divided by 5 = 6
