Answer
x^(2) x to the second power
Step-by-step explanation:
To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (3, 0) and (4, 2).
Now,
Since, The equation of line passes through the points (3, 0) and (4, 2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 0) / (4 - 3)
m = 2 / 1
m = 2
Thus, The equation of line with slope 2 is,
⇒ y - 0 = 2 (x - 3)
⇒ y = 2x - 6
Therefore, The equation of line passes through the points 3, 0) and (4, 2). will be;
⇒ y = 2x - 6

How do I solve 5(1 − x) + 2(x + 3) ?
Answers
Answer:
11-3x
Step-by-step explanation:
1) Multiply 5(1-x). To do this, you multiply 5 by both x and 1. You should get 5-5x.
1) Next, multiply 2(x+3). You should get 2x+6.
3) Finally, add like terms. Add 2x and -5x together and add 6 and 5 together. You should get -3x and 11.
The answer is 11-3x.

Which linear equation has a slope of 3 and a y-intercept of -2?
y = 3x + 2
y=3x-2
y=-2x + 3
y = -2x - 3
Answers
Answer:
y=3x-2
Step-by-step explanation:
3 is the coefficient of x (slope)
-2 comes after (y-int)
linear equation y = 3x-2 has a slope of 3 and a y-intercept of -2.
What is the Slope of a line?A line's slope can be determined by looking at its slope. The slope is determined mathematically as "increase over run" (change in y divided by change in x). There are several ways to find the slope, including standard form, slope-intercept form, and point-intercept form.
Given, A linear equation that has a slope of 3 and a y-intercept of -2.
Y-intercept of -2 means at x = 0 y would be -2
The slope-intercept form of a line is
y = mx + c
where m = slope
c = constant
Substituting the values in the given equation
-2 = 0 * 3 + c
c = -2
thus, the equation of the line,
y = 3x -2
therefore, The y-intercept of the linear equation y = 3x-2 is -2, and its slope is 3.

Researchers have noted a decline in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggest that the antioxidants in foods such as blueberries can reduce and even reverse these age-related declines, at least in laboratory rats (Joseph et al., 1999). Based on these results, one might theorize that the same antioxidants might also benefit elderly humans. Suppose a researcher is interested in testing this theory. The researcher obtains a sample of adults who are older than 65, and gives each participant a daily dose of a blueberry supplement that is very high in antioxidants. After taking the supplement for 6 months, the participants are given a standardized cognitive skills test and produce a mean score of . For the general population of elderly adults, scores on the test average μ and form a normal distribution with σ=9.
(a)-Can the researcher conclude that the supplement has a significant effect on cognitive skill? Use a two-tailed
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
Yes the researcher can conclude that the supplement has a significant effect on cognitive skill
b
[tex]d = 0.5778 [/tex]
c
The result of this hypothesis test shows that there is sufficient evidence to that the supplement had significant effect.The measure of effect size is large due to the large value of Cohen's d (0.5778 > 0.30 )
Step-by-step explanation:
From the question we are told that
The sample size is n=16
The sample mean is [tex]M = 50.2[/tex]
The standard deviation is [tex]\sigma = 9[/tex]
The population mean is [tex]\mu = 45[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o \mu =45[/tex]
The alternative hypothesis is [tex]H_a \mu \ne 45[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{M - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{50.2 - 45}{\frac{9}{\sqrt{16} } }[/tex]
=> [tex]z = 2.31 [/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > z )[/tex]
[tex]p-value = 2 * P(Z > 2.31 )[/tex]
From the z-table
[tex]P(Z > 2.31 ) = 0.010444[/tex]
=> [tex]p-value = 2 * 0.010444 [/tex]
=> [tex]p-value = 0.021 [/tex]
From the obtained values we see that [tex]p-value < 0.05[/tex]
Decision Rule
Reject the null hypothesis
Conclusion
There is sufficient evidence to conclude that the supplement has a significant effect on the cognitive skill of elderly adults
Generally the Cohen's d for this study is mathematically represented as
[tex]d = \frac{M - \mu}{\sigma }[/tex]
=> [tex]d = \frac{50.2 -45}{9 }[/tex]
=> [tex]d = 0.5778 [/tex]

Answers
Answer:
-15
Step-by-step explanation:
First combine like terms, aka the variables
-5n+4n-7=8
-1n-7=8
Then, isolate the variable by adding 7 to both sides
-1n-7+7=8+7
-1n=15
Finally, solve by dividing both sides by -1
-1n/-1=15/-1
n=-15
Answer:
n = -15
Step-by-step explanation:
I'll try my best to explain how I solved this
Equation:
-5n + 4n -7=8
Add the light terms on each side:
-n -7 =8
Separate the variables from the numbers:

What do the differences between the points (as shown on the graph) represent?
Please answer
Answers
Answer:
Answer:
They represent the rise and run of the graph.
Step-by-step explanation:
Step-by-step explanation:
The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)
The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).
The ratio of rise to run is the slope of the graph, which tells us how many steps should we take on the y-axis for every step we move forward on the x-axis.
They represent the rise and run of the graph.
The difference between the x-axis of the points represents the" run" of the graph( or how important you should run along x-axis to get to the coming point.) The difference between the y- axis of of the points represents the" rise" of the graph( or how important you should rise up the y- x is to get to the coming point).
The rate of rise to run is the slope of the graph, which tells us how numerous way should we take on the y- axis for every step we move forward on the x-axis.
