Answer:
x^2/3
Step-by-step explanation:
(x^4/3 × x ^2/3)^ 1/3
According to laws of indices powers are added if the base is same,
[x^(4/3 + 2/3) ] ^1/3
= (x ^ 6/3 ) ^ 1/3
= (x² )^ 1/3
= x ^ 2/3

Is B right? Or A?
Answer:
[tex]x<2[/tex]
Step-by-step explanation:
[tex]\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides}[/tex]
[tex]4x+9-9<17-9[/tex]
[tex]\mathrm{Simplify}[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}4[/tex]
[tex]=x<2[/tex]
Answer:
4x+9=17
-9 -9 subtract 9 on both sides to cancel 9 on one side of equation and subtracted on the other side
4x=8
divide 4 on both sides to get x by itself
x=8/4

You are planning a survey of starting salaries for recent computer science majors. In the latest survey by the National Association of Colleges and Employers, the average starting salary was reported to be $60,038. 5 If you assume that the standard deviation is $4300, what sample size do you need to have a margin of error equal to $500 with 95% confidence
Answer:
A sample size of 285 is needed.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Standard deviation is $4300
This means that [tex]\sigma = 4300[/tex]
What sample size do you need to have a margin of error equal to $500 with 95% confidence?
A sample size of n is needed. n is found when M = 500. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]500 = 1.96\frac{4300}{\sqrt{n}}[/tex]
[tex]500\sqrt{n} = 1.96*4300[/tex]
[tex]\sqrt{n} = \frac{1.96*4300}{500}[/tex]
[tex]n = 284.1[/tex]
Rounding up
A sample size of 285 is needed.

If <6≈<10and <5≈<7, which describes all the lines that must be parallel?
o Only lines r and s must be parallel.
o Only lines t and umust be parallel.
Lines r and s and lines t and u must be parallel.
O Neither lines r and s nor lines t and u must be parallel
From the image we can see that; Lines r and s and lines t and u must be parallel.
What are parallel lines?The term parallel lines refers to those lines that can not meet. We know parallel lines by the arrows that show us where they are pointing to.
Thus, from the image we can see that; Lines r and s and lines t and u must be parallel.

find all solutions (x,y) of the given system, where x and y are real numbers.
xy=8
y=-x^2
Work Shown:
xy = 8
x(-x^2) = 8
-x^3 = 8
x^3 = -8
x = cube root of -8
x = -2
y = -x^2
y = -(-2)^2
y = -4
You can use a graphing tool like Desmos or GeoGebra to plot the two curves. Notice they intersect at (-2,-4) to confirm the answer. See the diagram below.
