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.
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.

Step-by-step explanation:
[tex]\sf (\frac{4}{5})^3 \\\\[/tex]
This means that 4/5 repeats itself 3 times.
So,
[tex]\sf = \frac{4}{5} * \frac{4}{5} * \frac{4}{5} \\\\= \frac{64}{125} \\\\\rule[225]{225}{2}[/tex]
Hope this helped!
~AH1807Answer: Choice 2: 4/5 • 4/5 • 4/5 = 64/125
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
If y varies inversely with x
and y is 10 when x is 5,
then what is y when x is 2?
9514 1404 393
Answer:
25
Step-by-step explanation:
Inverse variation means ...
y = k/x
For the given values, we can find k to be ...
k = xy = (5)(10) = 50
Then for x=2, we have ...
y = 50/x
y = 50/2
y = 25 . . . when x=2
In a garden, 1/3 of the flower are yellow,1/6 of them are pink, and 1/3 of the remaining flowers are red.If there are 120 flowers, how many are red? How many are yellow? How many are pink?
Answer:
20 Red flowers
40 Yellow flowers
20 Pink flowers
Step-by-step explanation:
1/3 of 120 is 40
1/6 of 120 is 20
40+20=60
120-60=60
Remaining=60
1/3 of 60 is 20

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
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.

Answer:
A because when you add the angles up it has to equal 180
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

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

"bananas cost 89 cents each at the fruit stand.. Isabel has $11.75. how many bananas can she buy?" i forgot how to do this stuff pls help
Answer:
She can buy 13 bananas
Step-by-step explanation:
She has 11.75 and each banana costs .89
Start by dividing 11.75/.89 = 13.20
She will be able to buy 13 bananas total since she cannot buy a portion of a banana (0.2) so she will just have some leftover change.

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

Solve for x. Leave your answer in simplest radical form
Answer:
x = sqrt(39)
Step-by-step explanation:
Let y = common side of the two triangles.
Upper right triangle:
6^2 + y^2 = 10^2
y^2 = 100 - 36
y^2 = 64
y = 8
Lower left triangle:
5^2 + x^2 = 8^2
x^2 = 64 - 25
x^2 = 39
x = sqrt(39)
