3. If a+b=c, then what is the average value of a,b are c?

Answers

Answer:

The average value of a, b and c is [tex]\frac{2c}{3}[/tex]

Step-by-step explanation:

Average value:

Sum of all values by the number of values.

In this question:

3 values, a, b and c.

We have that:

[tex]A = \frac{a+b+c}{3}[/tex]

Since [tex]a+b = c[/tex]

[tex]A = \frac{a+b+c}{3} = \frac{c+c}{3} = \frac{2c}{3}[/tex]

The average value of a, b and c is [tex]\frac{2c}{3}[/tex]

Nielson Media Research wants to estimate the mean amount of time (in minutes) that full-time college students spend watching television each weekday. Find the sample size necessary to estimate that mean with a 15-minute sampling error. Assume 96% confidence level is desired. Also assume that a pilot study showed that the standard deviation is estimated to be 112.2 minutes.

Answers

Answer:

The sample size necessary is 237.

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 - 0.96}{2} = 0.02[/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 - 0.02 = 0.98[/tex], so Z = 2.056.

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.

Find the sample size necessary to estimate that mean with a 15-minute sampling error.

A sample size of n is necessary.

n is found when [tex]M = 15[/tex]

We have that [tex]\sigma = 112.2[/tex]

So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]15 = 2.056\frac{112.2}{\sqrt{n}}[/tex]

[tex]15\sqrt{n} = 2.056*112.2[/tex]

[tex]\sqrt{n} = \frac{2.056*112.2}{15}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.056*112.2}{15})^2[/tex]

[tex]n = 236.5[/tex]

Rounding up,

The sample size necessary is 237.

What is the x-intercept of the graph of Y= 4x-36

Answers

The x-intercept is -36.

y = 4x - 36
The y is your y-intercept.
The 4x is your slope. (4/1)
The -36 is your x-intercept.

The x - intercept of the line is at Point X(9, 0).

We have the following equation of a straight line -

y = 4x - 36

We have to find the x - intercept of the of this line.

What is the general equation of a straight line ?

The general equation of a straight line is as follows -

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question, we have -

y = 4x - 36

Now, comparing this line with the general equation of line -  y = mx + c, we get -

m = 4

c = - 36

for the x - intercept of the line, substitute y = 0. We get -

0 = 4x -36

4x = 36

x = 9

Hence, the x - intercept of the line is at Point X(9, 0).

Refer to the graph attached for more clarity.

Step-by-step explanation: The exponent tells you how many times you have to multiply the 4/5. Since the exponent is 3, we know to multiply 4/5 with itself 3 times, like this: 4/5 • 4/5 • 4/5, which will get us 64/125

What is the area of the parallelogram?

A parallelogram with base of 20 centimeters, height of 15 centimeters, and side length 21 centimeters.
82 centimeters squared
300 centimeters squared
315 centimeters squared
420 centimeters squared

Answers

Answer:

300 centimeters squared.

Step-by-step explanation:

Given that a parallelogram has a base of 20 centimeters, a height of 15 centimeters, and a side length 21 centimeters, to determine the value of its area, the following calculation must be performed:

Area = Base x Height

Area = 20 x 15

Area = 300

Thus, the area of the parallelogram is 300 square centimeters.

Step-by-step explanation:

Answer:

A) ∠ABC and ∠DEF

Step-by-step explanation:

Supplementary angles add up to 180 degrees total. So if you take 180 and subtract 118 you get 62.

∠ABC = 62

∠DEF = 118

180 - 118 = 62

180 - 62 = 118

118 + 62 = 180
