Answer:

y=x/3+2

Step-by-step explanation:

Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

3y=x+6

We need y so we divide both sides by 3 and we get

y=x/3+2

Answer:

y=1/3 + 2

Step-by-step explanation:

-x+3y=6

add x to both sides (if you add the same amount to both sides, the equation is still equal)

3y=-x+6

divide the whole thing by 3

y=1/3 + 2

so basically your slope is 1/3. That means you rise one, over three.

Plot a point at 2 on the y axis, which is the vertical line on the graph.

Go up one box, and then go right 3 and plot another point.

Keep doing the rise 1 over 3 until you have enough points for a line. 2 points should do, but more points on a graph = a better line.

By the way, slope-intercept form is y=mx+b.

m = slope (steepness of line, 1/3)    b = y-axis intercept (the place that the line touches the y axis)

If you're still stuck with linear equations, take your equation and put it into Desmos graphing calculator, which can be found with a simple search.

Answer:

\((\frac{1}{2}+\frac{\sqrt{3}}{2}i)^5=\frac{1}{2}-\frac{\sqrt{3}}{2}i\)

Step-by-step explanation:

Convert 1/2 + i√3/2 to rectangular form

\(\displaystyle z=a+bi=\frac{1}{2}+\frac{\sqrt{3}}{2}i\\\\r=\sqrt{a^2+b^2}=\sqrt{\biggr(\frac{1}{2}\biggr)^2+\biggr(\frac{\sqrt{3}}{2}\biggr)^2}=\sqrt{\frac{1}{4}+\frac{3}{4}}=\sqrt{1}=1\\\\\theta=\tan^{-1}\biggr(\frac{b}{a}\biggr)=\tan^{-1}\biggr(\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}\biggr)=\tan^{-1}(\sqrt{3})=\frac{\pi}{3}\\\\z=\cos\frac{\pi}{3}+i\sin\frac{\pi}{3}\)

Use DeMoivre's Theorem

\(\displaystyle z^n=r^n(\cos(n\theta)+i\sin(n\theta))\\\\z^5=1^5\biggr(\cos\biggr(\frac{5\pi}{3}\biggr)+i\sin\biggr(\frac{5\pi}{3}\biggr)\biggr)\\\\z^5=\frac{1}{2}-\frac{\sqrt{3}}{2}i\)

The surface area of the cylinder is 948m²

The area occupied by a three-dimensional object by its outer surface is called the surface area. The surface of a cylinder is expressed as ;

SA = 2πr(r+h)

Where r is the radius of the base and h is the height of the cylinder.

r =8m

h = 4m

SA = 2 × 3.14 × 8 (8+4)

SA = 78.96 × 12

SA = 947.52 m²

to the nearest whole number

SA = 948 m²

therefore the surface area of the cylinder is 948 m²

Let's add up the given scores to get: 97+38+88+75+83 = 381. Then we divide by 5 since there are five scores here. The mean we get is 381/5 = 76.2

So that explains the "76.2" mentioned.

Now we'll replace the "38" with "58" and repeat the same steps as above.

Add: 97+58+88+75+83 = 401

Divide by five: 401/5 = 80.2

The mean is now 80.2; it has increased compared to the previous mean. We can see that if we move any outliers closer to the main cluster, then the mean will be centered more around the main cluster. In the other direction, if we move the outlier further away from the cluster, then the outlier pulls on the mean. Think of a magnetic or gravitational pull.

The smaller outlier 38 made the mean of 76.2 to be smaller than it should be if we focused on the other values only. In short, if your data set has outliers, then the mean may likely not reflect the true center average value of the group. At that point, the median may be the next best thing or you could use a trimmed mean.

Answer:

$71.415 or $71.42 is the selling price and the taxing is 1

Step-by-step explanation:

This is because I just rounded that extra 5 to make the 41 cents into 42 cents also y=79.35(.9) is the equation you needed to solve so just put 79.35(.9) into a calculator and you'll get 71.415 also 10% turns into a decimal 0.10 and then you subtract it from 1 as a whole and you'll get 0.9. I'm not really a mathmatician but I just got done learning this so I know what to do.

The answer is:

g(x + 1) = 6x + 1

g(4x) = 24x -5

Work/explanation:

To evaluate, I plug in x + 1 into the function:

\(\sf{g(x)=6x-5}\)

\(\sf{g(x+1)=6(x+1)-5}\)

Simplify

\(\sf{g(x+1)=6x+6-5}\)

\(\sf{g(x+1)=6x+1}\)

------------------

Do the same thing with g(4x)

\(\sf{g(4x)=6(4x)-5}\)

\(\sf{g(4x)=24x-5}\)

Hence, these are the answers.

The mistake that Katie made in the stem and leaf diagram, was that she D. Missed a length.

Looking at the stem and leaf diagram, we see that there are 14 leaves. This means that there are 14 lengths of caterpillars. However, there are 15 lengths shown on the table.

This means that there is a length missing that Katie failed to account for. Upon close inspection of the stem and leaf plot, we find that the missing length is a second value of 70 because there are two lengths that are 70 but this is shown only once on the stem and leaf plot.

Step-by-step explanation:

The question is incomplete as it has missing options.

From the attachment, we have:

\((a)\ \frac{-7}{9}\)

\((b)\ \frac{-8}{2}\)

\((c)\ \frac{6}{5}\)

\((d)\ \frac{3}{-2}\)

All but 6/5 are negative numbers.

This is so because:

\((a)\ \frac{-7}{9}\) has a negative sign at the numerator

\((b)\ \frac{-8}{2}\) has a negative sign at the numerator

\((d)\ \frac{3}{-2}\)  has a negative sign at the denominator

Only \((c)\ \frac{6}{5}\) has positive integers at the numerator and denominator.

Answer:

9 years old

Step-by-step explanation:

Let maggie's age be m,

and let maggie's brother's age be b

b = 2m - 5,

m + b = 22

Substitute "2m - 5" for b in the second equation (substitution)

m + (2m - 5) = 22 -> Remove parenthesis

m + 2m - 5 = 22 -> Combine like terms

3m = 22 + 5 = 27 -> Divide either side by 3

m = 27/3 = 9

Solution: Maggie is 9 years old

Work Shown:

Focus on triangle DEC. We have angle C is 48 and D is 74. Let's find angle E.

D+E+C = 180

74+E+48 = 180

E+122 = 180

E = 180-122

E = 58

----------

In the sequences ABC and DEC, we have B and E as the second letters. The order is important because the angles must align properly (so we know how they pair up). Therefore, angle B = angle E because triangle ABC = triangle DEC.

Furthermore,

angle B = angle E

2x = 58

x = 58/2

x = 29

Experimental but not double-blinded study

Step-by-step explanation:

The type of study being described is an Experimental but not double-blinded study. That is because it is a study that has a control group, dependent variable, and an independent variable all used in order to acquire specifically targetted data from the results that are derived from the experiment itself. Also since the scientists/researchers know exactly which lab sections are getting the extra review material (independent variable), then that makes this a non-double-blinded study.

The probability that a student chosen at random did not get a B 0.283 The probability of a student not getting a B is the number of students who did not get a B divided by the total number of students.

Outcome can be an event, such as the sum of two dice, or it can be a variable, such as the number of heads from a coin toss.

In this case, there are 21 students who did not get a B (2 male A's, 19 female A's, and 10 female C's), compared to a total of 74 students. Therefore, the probability that a student chosen at random did not get a B

= 21/74

= 0.283

To calculate this probability, we used the total number of students who did not get a B (21) divided by the total number of students (74).

This gives us the probability that a student chosen at random did not get a B.

In addition to using this method to find the probability of a student not getting a B, we can also find the probability of a student getting a B by subtracting the probability of not getting a B from 1.

In this case, the probability of getting a B would be

1 - (21/74)

= 0.71622.

This method can be used to calculate the probability of any outcome given the probabilities of all other outcomes.

ANSWER

Table D

EXPLANATION

We know that one of these tables shows the ages and grades of the 17 girls on a club soccer team.

Every two-way table that shows the marginal frequencies, must include in the lower right cell the total number of items surveyed - in this case, that number must be 17. Thus, the tables could be either A or D.

Also, the sum of all marginal frequencies must be equal to the total. In other words, the sum of the values of the right column of the table must be 17 and the sum of the values of the lower row must be 17 as well.

Hence, since it is the only table that meets the requirements mentioned above, the correct two-way frequency table is table D.

RESULTS: The study revealed that a 1% increase in access to improved sanitation would reduce infant mortality by a rate of about two infant deaths per 1000 live births.

Answer:

5.75.

Step-by-step explanation:

The mean = (8+5+7+10+3+4+31+12)/ 8

= 80/8

= 10.

Now we calculate the difference of each value from the mean We take the absolute ( positive) differences

10 - 8 = 2

10 - 5 = 5

10 - 7 = 3

10 - 10 = 0

10-3 = 7

10 = 4 = 6

10 - 31 = 21

10 - 12 = 2

Sum of the differences = 46

and the mean deviation  is 46/8 = 5.75.
