2.) if the line is not vertical then it does not have an undefined slope
Jordan is calculating the slope of the trend line in the scatterplot below.
How can Jordan use the plot to check the reasonableness of his answer?
His slope should be positive because the coordinates of all the plotted points are positive.
His slope should be positive because the trend line is slanted up to the right.
His slope should be negative because there are plotted points not on the line.
His slope should be negative because the x-coordinate of each plotted point is less than the y-coordinate.
Answer: B
His slope should be positive because the trend line is slanted up to the right.
Step-by-step explanation:
from left to right the line is increasing upward so it is positive so this means both of the bottom answers are wrong. answer A. is wrong because even slopes that are negative have all points positive sometimes so this is not a valid reason. therefore this leaves us with the answer B, which is correct.
His slope should be positive because the trend line is slanted up to the right. which is the correct answer would be an option (B).
What is the Scatter plot?The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.
Jordan is calculating the slope of the trend line in the given scatterplot.
As per the given scatter plot, the required solution would be as:
Take two points (1,24) and (8,96)
So, slope = (96-24)/(8-1) = 72/7 = 10.28
The line is moving upward from left to right, hence it is positive, implying that both of the bottom solutions are incorrect. Answer A. is incorrect since even negative slopes can have all points positive at times, hence this is not a legitimate argument.
As a result, we are left with solution B, which is accurate.

X^2 + 5x + c find the value of c that makes each trinomial a perfect square
To make the trinomial a perfect square, we can complete the square. The value of c that makes the trinomial a perfect square is c = 25/4.
Explanation:To make the trinomial a perfect square, we need to find the value of c. We can do this by completing the square. The trinomial can be written as x² + 5x + c = (x + a)², where a is a constant. Expanding the right side, we get x² + 2ax + a² which is equal to x² + 5x + c. Comparing the coefficients of x, we have 2a = 5. Solving for a, we get a = 5/2. Substituting this value back into the expression, we have x² + 5x + (5/2)² = (x + 5/2)². Therefore, the value of c that makes the trinomial a perfect square is c = (5/2)² or c = 25/4.

The tallest man ever recorded was Robert Wadlow, who was 272 cm tall. The tallest woman on record was Zeng Jinlian. Her height was 91% of wadlow’s height. How tall was Zeng Jinlian.
(Round to the nearest cm.)
247.52 centimeters.
To find this answer, you have to find 91% of Robert Wadlow's height. To do that, you multiply 272 by 0.91, which gives you the height of Zeng Jinlian.

Sonia makes a wooden frame around a square picture. The frame is made of 4 congruent trapezoids. The shorter base is 9 in., the longer base is 12 in., and the height is 1.5 in. What is the area of the picture frame? PLEASE tell me why the answer is that answer.
Final answer:
The area of Sonia's picture frame is determined by calculating the area of one trapezoid with given dimensions and multiplying by four. The area of each trapezoid is 15.75 square inches, resulting in a total frame area of 63 square inches.
Explanation:
The area of Sonia's picture frame can be calculated by finding the area of one of the congruent trapezoids and then multiplying it by four, since there are four trapezoids making up the entire frame. The formula to calculate the area of a trapezoid is: Area = (1/2) × (base1 + base2) × height. In this case, the shorter base (base1) is 9 inches, the longer base (base2) is 12 inches, and the height is 1.5 inches. Substituting these values into the formula gives us: Area of one trapezoid = (1/2) × (9 in + 12 in) × 1.5 in = (1/2) × 21 in × 1.5 in = 15.75 in2. The total area of the frame is then four times this amount, which equals 63 in2. This answer explains how to calculate the area of a trapezoid and then applies the concept to find the total frame area.
A leaky pool loses 2 1/4 inches of water each day. Jermaine and Mildred are asked to determine the change in the amount of water in the pool over 5 days.
Jermaine’s Solution Mildred’s Solution
5(-2 1/4) 5(-2 1/4)
5(-2 -1/4) 5(-2 -1/4)
-10 -1/4 -10 -5/4
-10 1/4 -11 1/4
Which describes the reasoning used to determine whose solution is correct?
A. Jermaine is correct because -10 -1/4 equals -10 1/4.
B.Jermaine is correct because he distributed 5 correctly.
C.Mildred is correct because she multiplied 5 by –2 but not by -1/4.
D.Mildred is correct because she distributed 5 correctly.
Answer: D. Mildred is correct because she distributed 5 correctly.
Step-by-step explanation:
Since, the loss of water in one day = [tex]2\frac{1}{4}\text{ inches}[/tex]
⇒ The loss of water in 5 days = [tex]5(2\frac{1}{4})\text{ inches}[/tex]
⇒ The loss can be written with negative sign,
Thus, the expression that shows the changes in quantity of water in 5 days,
[tex]-5(2\frac{1}{4})[/tex]
[tex]=-5(2+\frac{1}{4})[/tex]
[tex]=5(-2-\frac{1}{4})[/tex]
[tex]=-10-\frac{5}{4}[/tex]
[tex]=-10-1\frac{1}{4}[/tex]
[tex]=-10-1-\frac{1}{4}[/tex]
[tex]=-11-\frac{1}{4}[/tex]
[tex]=-11\frac{1}{4}[/tex]
Since, the above steps are similar to that of Mildred's solution,
⇒ Mildred is correct.
Also, By the above explanation it is clear that jermaine incorrectly distribute 5 in his third steps.
⇒ Option D is correct.

The tax rate on Jerome James 112000 vacation home is 25 Mills the property is assessed at full value how much will Jerome pay in taxes this year
Answer: $2,800
Step-by-step explanation:
Given: The assessment value of Jerome's home= [tex]$112,000[/tex]
We know that to calculate the property tax, we need to multiply the assessment value of the property by the mill rate and then divide by 1,000.
Then, the property tax is given by :-
[tex]\text{Property tax}=\dfrac{\$112,000\times25}{100}\\\\\Rightarrow=\text{Property tax}=\$2,800[/tex]
Therefore, Jerome pay $2,800 as property tax in this year.
Answer:
[tex]Property tax=$2800[/tex]
Step-by-step explanation:
Given: The assessment value of Jerome's home is given as =[tex]112000[/tex]
Solution: Since we know that in order to calculate the property tax, we need to multiply the assessment value of the property by the mill rate and also divide by [tex]1000[/tex].
Then, the property tax is given as :-
[tex]Property tax=\frac{112000{\times}25}{100}[/tex]
[tex]Property tax=$2800[/tex]
Thus, Jerome pay $2,800 as property tax in this year.
