Answer:
[tex]\frac{-1}{7}[/tex] or 0.14
Step-by-step explanation:
To find slope you can use the formula
mx=[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
or
[tex]\frac{rise}{run}[/tex]
Rise over run:
Rise over run is the easiest of the two so we'll be using that one first for this question, but both should give you the same answer
To find rise over run, select the points and see how many points up or down you must got to make it the same level as the other point
In this case, the point (-3,1) would have a run of -1 because you have to move down one
To find run, now that you have rise start from that point and count how far you have to go to get to the next point. You should be going in a straight line.
The run would be 7.
Now you make it a fraction/division problem
[tex]\frac{rise}{run} =\frac{-1}{7}[/tex]
-0.14285714285714285714285714285714 <- decimal value
-0.14
Depending on what it means by reduce, your answer will either be -1/7 or the decimal. Use the reduced decimal value if it's asking for a decimal
I've included a picture in case my explanation was not satisfactory or you need a visual.
Slope form:
Identify the two points
First one will be (-3,1)
Second one would be (4,0)
Now label them
-3 will be x1
1 is y1
4 is x2
0 is y2
You will be using [tex]\frac{y2-y1}{x2-x1}[/tex]
Put the values into the equation
[tex]\frac{0-1}{4--3} =\frac{0-1}{4+3} =\frac{-1}{7}[/tex]
You get the same thing as the previous way.
Same answer
Visuals also included

You conduct a simulation regarding students scores on a physics test. Your null hypothesis is
that the mean score on the test is less than or equal to 80 points. Your alternative hypothesis is
that the mean score is greater than 80 points.
You determine that the results of your simulation have a p-value of 0.06. What does this mean?
Answers
Under the tested hypothesis, the outcome of the simulation has a probability of 6%. With a significance level of 5%, you should FAIL to reject the null hypothesis.
The p-value is the probability of getting true null hypothesis.
What is Null Hypothesis and Alternative Hypothesis?Null hypothesis is a hypothesis of a test which assumes that there is no statistical relationship between two variables. This is the hypothesis which is being testes.
Alternative hypothesis assumes that there is a relationship between two variables.
Given that,
You conduct a simulation regarding students scores on a physics test.
Null hypothesis is that the mean score on the test is less than or equal to 80 points.
Alternative hypothesis is that the mean score is greater than 80 points.
p value = 0.06 = 6%
This means that there is only a 6% that the null hypothesis of yours is true.
So the p value tells you the probability of getting a true null hypothesis.
Hence the p value is the probability of getting true null hypothesis.

If using the method of completing the square to solve the quadratic equation x^2-20x+33=0x
2
−20x+33=0, which number would have to be added to "complete the square"?
Answers
Answer:
The complete square of the given quadratic equation
( x - 10)² = 67
The solution of the quadratic equation
x = 18.2 and x = 1.8
Step-by-step explanation:
Step(i):-
Given that the quadratic equation
x² - 20 x +33 =0
x² - 2(10) x +(10)²-(10)²+ 33 =0
By using (a-b)² = a² -2ab + b²
( x - 10)² -100 +33 =0
( x - 10)² - 67 =0
( x - 10)² = 67
Step(ii):-
The complete square (x - 10)² = 67
x -10 = ±√67
x -10 = ± 8.1853
x -10 = 8.2 and x -10 = -8.2
x = 10+8.2 and x = 10 -8.2
x = 18.2 and x = 1.8
Is 30% of 70 is the same as 3/7 of 70?
Answers
Answer:
No
Step-by-step explanation:
30% is the same as 3/10
3/7 is about the same as 43%
There is a difference among the percentage so no it's not correct
Yes, the value 30% of 70 is the same as 3/7 of 70.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
To show this mathematically, we can start by calculating 30% of 70:
30% of 70 = (30/100) x 70
= 0.3 x 70
= 21
Now, let's calculate 3/7 of 70:
3/7 of 70 = (3/7) x 70
= 30/100 x 70
= 0.3 x 70
= 21
As we can see, both calculations give us the same result of 21. Therefore, 30% of 70 is the same as 3/7 of 70.

Let's calculate the slope (or 'm') using
Slope or m = (Y2 -Y1) ÷ (X2 -X1)
Slope ('m') = (-3 -0) / (0, - -6) = -3 / 6 = -1/2
Then we calculate the equation using:
(y - y1) = m • (x -x1)
(y - 0) = -1/2 * (x - -6)
y = -1/2 x -3

x ≤ 7.5
Step-by-step explanation:
First, get x alone by multiplying both sides by 3 (to get rid of the fraction)
3 (1/3x) ≥ 3(2.5)
x ≤ 7.5
(The sign will flip whenever you multiply or divide in an inequality)
Since the sign is 'less than or equal to' you need a closed dot on 7.5, and it will be a ray pointing left, because x will be a number smaller (aka less than) than 7.5

Barry wants to make a drawing that is 1/2 the size of the original. If a tree in the original drawing is 11 inches tall and 5 inches wide,
Answers
Answer:
Barry's drawing is 5.5 in tall and 2.5 in wide.
Step-by-step explanation:
We are given that
Height of tree, h=11 in
Width of tree, b=5 in
We have to find the size of the original.
Size of drawing is 1/2 size of the original
Therefore,
Height of drawing, h'=[tex]\frac{1}{2}\times 11[/tex]in
Height of drawing, h'=5.5 in
Width of drawing tree=[tex]\frac{1}{2}\times 5[/tex]
Width of drawing tree=[tex]2.5in[/tex]
Hence, Barry's drawing is 5.5 in tall and 2.5 in wide.
How many more people like to swim than hike?

The number of people who likes to swim than hike is given by the equation A = 2 people
What is an Equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.
It demonstrates that the expressions on the left and right sides are connected in the same way.
An equation has components like as coefficients, variables, operators, constants, terms, expressions, and the equal to sign. The "=" sign and terms on both sides are required when generating an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of people who likes to swim be s= 4 people
Let the number of people who likes to hike be h = 2 people
Let the number of people who likes to bike be b = 3 people
Now , the equation will be
The number of people who likes to swim than hike A = number of people who likes to swim - number of people who likes to hike
The number of people who likes to swim than hike A = s - h
The number of people who likes to swim than hike A = 4 - 2
The number of people who likes to swim than hike A = 2 people
Hence , the number of people who likes to swim than hike is A = 2 people
