If the area of a square is an odd perfect square, the perimeter of the square will be even.
No conclusion can be reached based on the law of syllogism.
Answers
Answer:
C) If the area of a square is an odd perfect square, the perimeter of the square will be even.
Step-by-step explanation:
Just did it on edge.
Option 3 - If the area of a square is an odd perfect square, the perimeter of the square will be even is correct.
We have the statements given in the question.
We have to investigate the conclusion that can be drawn using the law of syllogism.
What is Law of Syllogism ?The Law of Syllogism says that if the following two statements are true:
→ If p, then q.
→ If q, then r.
Then, the following statement is also true -
→ If p, then r.
According to the question, we have -
→ P(If the area of a square is an odd perfect square) ,Q(then the side length of the square will be odd).
→ Q(If the side length of the square is odd), R(then the perimeter of the square will be even).
Now, in the above statements, q is true for p and r is true for q.
Therefore, Option 3 is correct.

The figure below is a rectangular box in which EFGH and ABCD are rectangles and BF is perpendicular to planes EFGH and ABCD. Use the figure to complete parys a through e.
Answers
Answer:
Step-by-step explanation:
Given question is incomplete: Find the compete question in the attachment.
a). Skew lines neither the parallel lines nor they intersect each other.
Two pairs of skew lines are BF and EH, & CG and EF.
b). Since EFGH and ABCD are rectangular planes and BF and DH are perpendicular to them,so both will be the altitudes between the planes.
Therefore, BF and DH will pe parallel.
c). BD and DH are the diagonals of the planes parallel to each other.
Therefore, BD and DH will be parallel.
d). Since BD and plane EFG don't intersect each other, so the solution will be an empty set.
e). HG is perpendicular to DH. So,the planes BDH and FHG containing these lines will be perpendicular to each other.

Answer:
$24,890.46, $25,109.59
Step-by-step explanation:
Given:
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)

What is the median for the following scores for Mr.smiths first test? 55,42,78,99,69,83,74,83,97
Answers
Answer:
78
Step-by-step explanation:
The median of a set is the middle number.
First, we have to put the numbers into numerical order.
42, 55, 69, 74, 78, 83, 83, 97, 99
Then, count the number of numbers, which is 9
Then, the middle of 9 is 5, because:
1, 2, 3, 4, 5, 6, 7, 8, 9
There are four numbers on either side of 5.
Lastly, find the 5th number in the set.
It is 78. So, the median of the set is 78.
Answer:
78
Step-by-step explanation:
to know the median you should first order the numbers from the smallest to the largest. that is
42,55,69,74,78,83,83,97,99
you take the number in the middle or if the number found in the middle are 2 then you add them up and divide them by 2 because they are 2. so in this case the number is only one which is 78 so that is the median.

A cyclist travels 45 miles in 3 hours. What is the cyclist's speed?
Hint: Use the formula: d = r x t (distance = rate x time)
Remember that division and multiplication are INVERSE operations. So, 45 = r x 3
so you will have to divide the distance by the time to get the rate.
45 ÷ 3 to find the rate
A: 15 miles per hour

Answers
Answer:
[tex]y = -3x+11[/tex]
Step-by-step explanation:
I accept your challenge!
First we know that a equation of the line is a linear equation, and its equation is:
[tex]y = mx+b[/tex]
[tex]m: \text{slope}\\b: \text{y-intercept}[/tex]
In this context, the slope, defined as the steepness of a line is characterized as the ratio of RISE (the difference in the y-coordinates, the vertical change) over the RUN (the difference in x-coordinates, the horizontal change).
[tex]$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} $[/tex]
Once we know two points where the line goes through, we can get the slope, once we know the change in y and x.
I will take [tex](3,2)[/tex] as Point 1 and [tex](4,-1)[/tex] as Point 2.
So, [tex]x_{1}=3 \text{ and } y_{1}=2\\x_{2}=4 \text{ and } y_{2}=-1[/tex]
[tex]$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{-1-2}{4-3} $[/tex]
[tex]$m=\frac{-3}{1}=-3 $[/tex]
Now we have to find the y-intercept:
To do so, think about the the points given and the nearly finished equation, we can find b with those two informations.
Our currently equation of the line is:
[tex]y = -3x+b[/tex]
Using the points, take Point 1 as an example, it says that when [tex]x = 3, y = 2[/tex], so plugging it in the equation:
[tex]2 = -3(3)+b\\2 = -9+b\\11 = b[/tex]
Taking the Point 2
[tex]-1 = -3(4)+b\\-1 = -12+b\\11 = b[/tex]
Now we found [tex]b[/tex]! The equation is complete!
[tex]y = -3x+11[/tex]

Answers
Answer:

Step-by-step explanation:
Answer:
I believe the slope is 1.
Step-by-step explanation:
using the points, (2,4) and (-5,-3), I tried to find out the difference in point if both x and y spots. Then I figured out that the space between -5 and 2( the x-coordinates) is 7, and the space between 4 and -3( the y-coordinates) is 7 as well. No I add these numbers into y/x which is 7/7 and that so happens to be equal to 1 as a whole number.
What are the intercepts of y=8x-18
Answers
Answer:
[tex]x-intercept=\frac{9}{4}[/tex]
[tex]y-intercept=-18[/tex]
Step-by-step explanation:
The y-intercept is where x is equal to 0, and the x-intercept is where y is equal to 0, so:
[tex]x-intercept=(x,0)\\y-intercept=(0,y)[/tex]
The equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
m is the slope and b is the y-intercept, so the y-intercept is -18.
Now set the value of y to 0 to find the intercept of x:
[tex]0=8x-18[/tex]
Solve for x. Add 18 to both sides:
[tex]0+18=8x-18+18\\18=8x[/tex]
Divide both sides by 8:
[tex]\frac{18}{8}=\frac{8x}{8} \\\\\frac{18}{8} =\frac{9}{4}\\ \\x=\frac{9}{4}[/tex]
The x -intercept is [tex]\frac{9}{4}[/tex].
[tex]x-intercept=(\frac{9}{4},0)\\\\y-intercept=(0,-18)[/tex]
:Done
Step-by-step explanation:
Step 1: Find the y-intercept
To find the y-intercept, you need to set the x-value to 0 and solve for y.
[tex]y = 8(0) - 18[/tex]
[tex]y = 0 - 18[/tex]
[tex]y = -18[/tex]
[tex](0, -18)[/tex] ← y-int
Step 2: Find the x-intercept
To find the x-intercept, you need to set the y-value to 0 and solve for x.
[tex]0 + 18 = 8x - 18 + 18[/tex]
[tex]18 / 8 = 8x / 8[/tex]
[tex]2.25 = x[/tex]
[tex](2.25, 0)[/tex] ← x-int

distance between (-3,1) (1,5)
Answers
Answer & Step-by-step explanation:
For this problem, we will use the distance formula.
[tex]d=\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.
[tex]d=\sqrt{(1-(-3))^2+(5-1)^2}[/tex]
[tex]d=\sqrt{4^2+4^2}[/tex]
[tex]d=\sqrt{16 + 16}[/tex]
[tex]d=\sqrt{32}[/tex]
[tex]d=5.657[/tex]
So, the distance between (-3,1) and (1,5) is 5.657 units.
