a line passes through tge points (1,-3) and (4,6) what is the zero of this line ?
Answer:
The zero of the line is (2,0)
Step-by-step explanation:
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
We are given the points (1,-3) and (4,6). Substituting:
[tex]\displaystyle y+3=\frac{6+3}{4-1}(x-1)[/tex]
Operating:
[tex]\displaystyle y+3=\frac{9}{3}(x-1)[/tex]
[tex]y+3=3(x-1)[/tex]
The zero of this line can be found by making y=0 and solving for x:
0+3=3(x-1)
3=3x-3
Adding 3:
6=3x
Solving:
x = 2
The zero of the line is (2,0)

You are to take a multiple-choice exam consisting of 100 questions with 2 possible responses to each question. Let x represent the number of correct responses on the test. A) What is your expected score on the exam?B) Compute the variance and standard deviation of x.
Answer:
50 ;
25 ;
5
Step-by-step explanation:
Given that:
Number of multiple choice questions = 100
Number of possible responses = 2
Hence, probability of success, p = 1/2 = 0.5
Using normal approximation :
The expected score = mean = n*p
Expected score (X) = 100 * 0.5 = 50
standard deviation = std(X) = √
Var(X) = n*p*q
q = 1 - p = 1 - 0.5 = 0.5
Variance = Var(X) = (100 * 0.5 * 0.5)
Var(X) = 25
Var(X) = 25
The Standard deviation (Std) = √Var(X)
Std(X) = √25
Std(X) = 5

Karen is planting a tree. She wants to use three guide wires to stabilize the tree. If Karen places the guide wires 8 feet up
the trunk and 6 feet from the base, how much total wire will she need for both guide wires?
Answer:
Karen will need 42 feet to use 3 guide wires to stabilize the tree.
Step-by-step explanation:
1 guide wire = 8 feet up + 6 feet from base
1 guide wire = 14 feet
3 guide wires = 14 feet + 14 feet + 14 feet
3 guide wires = 42 feet

On O n. 108 O c. 12 D. 14
Which equation(s) represents a nonproportional relationship? Select all that apply
O y=3x
O y=3x-2
O y=x+1
O y=-ax
Answer:
The correct answer is option one and option four.
Step-by-step explanation:
y=3x and y=-ax are equal because they are opposites and can match to the other by the same numbers. I hope you know what I mean by that, I prob didn't say it right. But the other two opstions are not correct because they are different kind of equations, (additions, subtraction, multiplication, and division) I hope you understand. Good luck on future questions!!

Danielle created a painting using only similar hexagons.
Which statement about the hexagons must be true?
The hexagons are all the same size and shape.
The hexagons have corresponding sides that are proportional.
The hexagons have corresponding angles that are not congruent.
The hexagons are different shapes but the same size.
Answer:
The hexagons have corresponding sides that are proportional
Step-by-step explanation:
Hexagon is a polygon that consists of six sides and six angles.
Two polygons are said to be similar under the following conditions:
1. Corresponding angles of the hexagons are congruent.
2. Corresponding sides of the hexagons are proportional.
As hexagons are similar, the following statement must be true:
The hexagons have corresponding sides that are proportional.
Answer:
The hexagons have corresponding sides that are proportional.

Mr. Hayes has 111 straw bundles to use for bedding in his horse stalls. what is the greatest number of stalls he can fill if each stall holds exactly 4 bundles of straw?
Answer:
27 stalls
Step-by-step explanation:

So he can fill at most 27 stalls completely
Find the value of c that completes the square.
m^2 + 32m + c
Answer:
c=256
Step-by-step explanation:
m²+32m+c=m²+32m+(32/2)²-(32/2)²+c
=m²+32m+16²-16²+c
=(m+16)²-256+c
for it to be a complete square -256+c=0
or c=256
A large nationwide company with 1200 employees claims that the number of days missed by its employees due to illness is below the national average of 7. A random sample of 40 employees resulted in a mean of 6.6 days with a standard deviation of 1.8. The hypothesis test resulted in a p-value of 0.084. Which of the following statements is true?
A. There is a 10% chance that the null hypothesis is true and a 8.3% chance that the alternative hypothesis is true.
B. There is a 8.3% chance that the mean number of days missed by employees at the company is below 7.
C. Since the probability that the mean number of days is below 7 is small, the null hypothesis is likely true.
D. If the mean number of days missed the company is 7 the probability of obtaining a sample mean of 66 days or lower is 0.063.
The last part of the question before the options is meant to be;
The hypothesis test using α = 0.1 resulted in a p-value of 0.084. Which of the following statements is true?
Answer:
B: There is a 8.3% chance that the mean number of days missed by employees at the company is below 7.
Step-by-step explanation:
Significance value is α = 0.1
p-value = 0.084
Now, we want to test the claims that the number of days missed by its employees due to illness is below the national average of 7.
Now the p-value is basically a probability.
Thus, p = 0.084 can be written as 8.4%
It seems this 8.4 is an approximate version of 8.3 because the options use 8.3%.
Thus, Option B is the closest answer.

PLEASE HELPP Which equation is parallel to y = –3 x + 4 and passes through the point (–3 , 4)? y = –3 x – 5 y = 13 x + 3 y = –3 x + 15 y = 13 x + 5
Answer:
A.(-3,4) is your answer.
Step-by-step explanation:
-3x+4
For A:
x=-3
y=4
Plug in 3 where x is and multiply -3 x -3, which equals 0.
Then you plug in 4 where y is, so then your equation is (4=0+4)
Then you add 0 +4, which sum is 4.
Final equation is 4=4, so yes your answer is A. (-3 , 4)

You have discovered another alien. Find the correct rescue path before answering this question. Which statements are true about the equation of the line used to save this alien? The y-intercept is not visible on the graph. The slope does not exist for this line. The y-intercept is positive. The line crosses the x-axis at –3.
The correct answers are option A and option D.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction
From the given graph it is clear that the spaceship is located at (-4,3). The alien is at (-2, -3).
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
y - 3 = (-3 -3 ) / (-2 + 4) x (x + 4)
y - 3 = -3x -12
y = -3x -9
The equation of the line is;
y = -3x -9 {equation 1}
Slope intercept form of a line is
y = mx + b {equation 2} ,
where m is the slope and b is the y-intercept.
On comparing the equation (1) and (2) we get
It means,
Slope = -3
y-intercept = -9
Points from -6 to 6 are labeled on y-axis. The y-intercept is -9, so it is not visible on the graph.
Option A is correct.
Substitute y=0 in equation (1) to find the x-intercept.
Divide both sides by 3.
x-intercept is -3. It means the line crosses the x-axis at -3.
Option D is correct
Therefore, the correct options are A and D.
