Annie loved the first novel she read by Danielle Steel. Ms. Steel has just published a new novel, and it got great reviews. Therefore, it is likely that Annie would like that novel too which means that the argument is inductive and it is a weak one.
What is an Inductive argument?This is a type of argument which is characterized by the arguer believing that the truth of the premises provides only good reasons to believe the conclusion is probably true.
In this scenario since Annie liked the author's previous books and the new one had great reviews then it is probably true that she would also like it and it is a weak one because assuming the premises are true,then it is probable for the conclusion to be false.

Find the area of each of these rectangles
Find the other endpoint of the line segment with the given endpoint -5, 2 and midpoint 2, -5
Answer:
( 9, -12 )
Step-by-step explanation:
Mario's Math Tutoring
you have the midpoint
2, -5
use the midpoint formula
(x1+x2)/2 , (y1+y2)/2
to get the endpoint
x :
(-5+x2)/2 = 2
(-5+x2) = 4
-5+x2 = 4
x2 = 9
y:
(2+y2)/2 = -5
(2+y2) = -10
2+y2 = -10
y2 = -12

A study was performed with a random sample of 3000 people from one church. What population would be appropriate for generalizing conclusions from the study, assuming the data collection methods used did not introduce biases
The population would be set of all Christians of that particular church from where the random samples is collected.
According to the questions,
A study was performed with a random sample 3000 people from one church. In order to find appropriate population for generalizing conclusions
The population would be set of all Christians of that particular church from where the random samples is collected.
This is because random samples is collected only from the particular church, so its generalization can only be the possible to large population of that church. we can generalize to whole of that church because it is given that there was no bias is introduced.Hence, the population would be set of all Christians of that particular church from where the random samples is collected.

A manufacturer must test that his bolts are 4.00cm long when they come off the assembly line. He must recalibrate his machines if the bolts are too long or too short. After sampling 81 randomly selected bolts off the assembly line, he calculates the sample mean to be 3.97cm. He knows that the population standard deviation is 0.14cm. Assuming a level of significance of 0.01, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines
The p-value(0.0538) is greater than the given significance level of 0.01. So, there is no sufficient evidence to show that the manufacturer needs to recalibrate the machines.
What is the test statistics formula for finding the p-value approach of hypothesis testing?The test statistics formula for finding the z-score is,
z = (X - μ)/(σ/√n)
Where,
X = sample mean
μ = population mean
σ = population standard deviation
n = sample size
With this z-score, the p-value is calculated. If p > α, then the null hypothesis is not rejected, and if p < α, then the null hypothesis is rejected.
Calculation:It is given that,
The population mean μ = 4.00
The sample size n = 81
The sample mean X = 3.97
The standard deviation σ = 0.14
and the significance level α = 0.01
So, the hypothesis is:
The null hypothesis: H0: μ = 4
The alternative hypothesis: Ha: μ ≠ 4
Thus, the test statistic value is,
z = (X - μ)/(σ/√n)
= (3.97 - 4)/(0.14/√81)
= - 0.03/0.015
= -1.928
So, for z = -1.928, the p-value is 0.053855
Since p > 0.01, there is no sufficient evidence to show that the manufacturer needs to recalibrate the machines.

#SPJ1
Answer:
The plane is at an angle that is neither parallel nor perpendicular to the base of the cone.
Step-by-step explanation:
The plane doesn't need to be at an exact angle of 45 degrees. The most important thing is that the angle isn't parallel or perpendicular to the base of the cone, but it has to be non-zero without intersecting the base itself. It also only intersects one of the cones when looking at a double-cone.

Answer:
A) Equation of the line of best fit: y = -5x + 62
B) y = -3
Explanation:
Given points: {(5, 38), (6, 34), (7, 27), (8, 21), (9, 17), (10, 14)}
Plot these points on the graph and draw a straight line between them.
A)
The points (7, 27), (9, 17)
Find slope:
[tex]\sf slope: \dfrac{17-27}{9-7} = -5[/tex]
Equation:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]\sf y - 27= -5(x - 7)[/tex]
[tex]\sf y = -5x + 35 + 27[/tex]
[tex]\sf y = -5x + 62[/tex]
B) If x = 13, then approximate value of y is
insert x = 13 in equation
y = -5x + 62
y = -5(13) + 62
y = -3
The answers are :
A) y = -5x + 64
B) -1
Part (A) :
Finding the slope : Take the points (6, 34) and (10, 14)
m = Δy/Δx
m = 14 - 34 / 10 - 6
m = -20/4
* m = -5 *
Using point slope formula to find equation :
y - y₁ = m (x - x₁)
y - 34 = -5 (x - 6)
y - 34 = -5x + 30
y = -5x + 64
Part (B) :
Substitute x = 13 in the line of best fit equation
y = -5(13) + 64
y = -65 + 64

The length of a rectangle is 3 less than twice the width. Determine how the area will change if the length of the rectangle is increased by 5 and the width is decreased by 2. Show your work.
The change in the area is represented by the expression ΔA = 9 · x + 4, where x is the original width of the rectangle.
What is the change in the area of the rectangle if side lengths are changed?
By geometry we know that the area of a rectangle is equal to the product of its width (x) and length (y). Based on the statement, the original rectangle is equal to:
A = x · y
A = x · (2 · x - 3)
And the change in the area is:
A + ΔA = (x + Δx) · (y + Δy)
A + ΔA = x · y + Δx · y + Δy · x + Δx · Δy
ΔA = Δx · y + Δy · x + Δx · Δy
ΔA = (2 · x - 3) · Δx + Δy · x + Δx · Δy
ΔA = 2 · (2 · x - 3) + 5 · x + 10
ΔA = 9 · x + 4
