Write an equation in slope intercept form that contains the points (-6,3) and
(-2,1)..
Answer:
y= (-1/2)x+1
Step-by-step explanation:
The general equation of a line in the slope intercept form is y= mx+b, where
m = the slope, and b = y-intercept (where the line crosses the y-axis)
for points (x1 = -6, y1 = 3) and (x2 = -2, y2 = 1)
m= (y2-y1)/ (x2-x1) = (1 - 3)/ (-2 - -6) = -2 / 4 = -1/2
the equation is now y= (-1/2)x+b
substitute the x and y coordinates of any of the points in the equation
for point (-2, 1) we will have 1 = (-1/2)(-2)+b, so b=1
The equation in slope intercept form that contains the points (-6,3) and
(-2,1) is y = (-1/2)x+1
Dr. Reyes is examining whether exercise is linked to mood. She recruits a sample of college students and asks them to answer whether they exercised at least three times last week (yes or no) and to rate their mood in the last week (1: Not happy at all to 5: Very happy). Her results show that students who exercised in the last week also reported happier moods. Can Dr. Reyes make a causal inference from her study
The answer to whether Dr. Reyes can make a causal inference from the study is;
No, she can't make a casual inference from the study because she met only one of the three criteria's for causality.
To answer this question, we need to know the conditions for causality in statistics research because causality gives the relationships such that a change in one variable would have to result in a change in another variable.
Now, the three conditions are;
1) Covariation; This condition means that the causal variable must have to vary with with the variable it is assumed to cause in a systematic manner.
2) Temporal precedence; Thus condition simply means that cause must precede effect. In summary it denotes that the variable that has the causal effect must come before the effect that it is meant to cause.
3) Control for extraneous variables; This condition means that results of an experiment or research must not be due to factors outside of the experiment/research
Now, in our question, he fulfilled the covariation condition because the
result of the research is tied to the responses from the sample students.
However, she did not fulfill the temporal precedence because the cause of
their moods did not precede the effects in his research.
Also, she did not fulfill the condition of control of extraneous variables
because other factors outside of the research itself may have affected their
moods.

Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is Taylor's reasoning correct?
Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.
No, Taylor's resoning is incorrect because 2,800,000 = [tex]2.8 * 10^{6}[/tex]
From the question, we are given:
2,800,000 .
2,800,000 in scientific notation is [tex]2.8 * 10^{6}[/tex].
The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.
Therefore, Taylor's reasoning is incorrect.

Step-by-step explanation:
Graphically, an equation is even if it is symmetrical across the y-axis. An equation is odd if it is symmetrical after folded over y and x. An equation is neither if it fulfills neither requirement.
Algebraically, an equation is even is f(x) = f(-x), and an equation is odd if f(-x) = -f(x).

( 5a^2b^3)(4ab^5)
Answer:
20a^3 b^8
Step-by-step explanation:
( 5a^2b^3 ) ( 4ab^5 )
= ( 5 . a^2 . b^3 ) ( 4 . a . b^5 )
= ( 5 . 4 ) ( a^2 . a ) ( b^3 . b^5 )
= 20 ( a^2 . a^1 ) ( b^3 . b^5 )
= 20 ( a^( 2 + 1 ) ) ( b^( 3 + 5 ) )
= 20 ( a^3 ) ( b^8 )

You and 3 friends are going to the country fair. You have a coupon that will save your group $20. If the total bill to get into the fair was $100, how much does one regular price ticket to the fair cost?
Answer:
30$
Step-by-step explanation:
lets assume you didn't have a coupon then the total bill would have been 120$
so for 4 friends including u the bill would have been 120$
: 4 friends = 120 $
for : 1 friend = x$
cross multiply
4x = 120 × 1
4x =120
divide both sides by the coefficient of x
x =120 \ 4
x = 30$
therefore: 1 friend = 30$
A cricket bat is bought for $400. Later, it is sold with a loss of 15%. How much is the cricket bat sold for? =
After selling the cricket bat, how much money has been lost? Give your answer to two decimal places because it is a currency.=
Answer:
$340.00
Step-by-step explanation:
What I like to do first is find 10% of the number.
So 10% of 400 would be $40.
Then find half (5%) of the 10% ($40), which would be $20.
Add the $40 + $20 to get $60.
Then take $400 and subtract $60,
which gives you $340.00
What is the sign of a• (-b/b) when a=0 and b < 0
Answer:
Positive
Step-by-step explanation:
A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).
y -(-8) = -6(x - 2)
y -(-8) = -6x + 12
y -(-8) + 8 = -6x + 12 + 8
y = -6x + 20
Explain why the work is not correct.
Answer:
The student should subtract 8 from each side not add 8
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -8 = -6(x -2)
y+8 = -6(x-2)
Distribute
y+8 = -6x+12
Subtract 8 from each side
y+8-8 = -6x+12-8
y = -6x+4
The student should subtract 8 from each side not add 8
Answer:
y -(-8) = -6(x - 2)
y -(-8) = -6x + 12
y -(-8) + 8 = -6x + 12 + 8 (this step is incorrect as minus into minus is plus therefore when taking 8 to the right hand side we must subtract it from the left hand side
y = -6x + 20
the correct equation would be : y= -6x+4
