The cable company takes an SRS of 250 of the approximately 15,000 households who subscribe to them. They found that 75, percent of the sampled households watch sports on television at least once a month. The company is considering taking more samples like this. Suppose that it is actually 70, percent of their total subscribed households who watch those sports.
Let p represent the proportion of a sample of 250 households that watch sports on television at least once a month.
What are the mean and standard deviation of the sampling distribution of p?
Answer:
The mean of the sampling distribution of p is of 0.7 and the standard deviation 0.029
Step-by-step explanation:
We use the Central Limit Theorem to solve this question. So
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Percentage of 70%, sample of 250.
This means that [tex]p = 0.7, n = 250[/tex]
Mean:
[tex]\mu = p = 0.7[/tex]
Standard deviation:
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.7*0.3}{250}} = 0.0290[/tex]
The mean of the sampling distribution of p is of 0.7 and the standard deviation 0.029
Answer:
μp^ = 0.7
σp^ = √0.7(0.3)/250

F(t) = 212 - 61
what the value of t when F(t)= 140 ?
Answer:
[tex]t = -7\ \ \ or\ \ t = 10[/tex]
Step-by-step explanation:
Given
[tex]f(t) = 2t^2 - 6t[/tex]
Required
Find t, when [tex]f(t) = 140[/tex]
Substitute 140 for f(t) in [tex]f(t) = 2t^2 - 6t[/tex]
[tex]140 = 2t^2 - 6t[/tex]
Divide through by 2
[tex]\frac{140}{2} = \frac{2t^2 - 6t}{2}[/tex]
[tex]70 = t^2 - 3t[/tex]
[tex]t^2 - 3t = 70[/tex]
Subtract 70 from both sides
[tex]t^2 - 3t - 70= 70 - 70[/tex]
[tex]t^2 - 3t - 70= 0[/tex]
Expand
[tex]t^2 -10t + 7t - 70 = 0[/tex]
Factorize:
[tex]t(t - 10) + 7(t - 10) = 0[/tex]
[tex](t + 7)(t - 10) = 0[/tex]
Split:
[tex]t + 7 = 0\ \ \ or\ \ t - 10 = 0[/tex]
[tex]t = -7\ \ \ or\ \ t = 10[/tex]
Hence, the values of t are -7 and 10

Find the missing side of each triangle. Round your answer to the nearest tenth if necessary.
Answer:
[tex]1.\ x = 5\ in[/tex]
[tex]2.\ x = 5\ mi[/tex]
[tex]3.\ x = 8.6\ km[/tex]
[tex]4.\ x= 14.1\ mi[/tex]
Step-by-step explanation:
Given
See attachment for triangles
Required
Determine the missing sides
All 4 triangles are right-angled. So, to calculate the missing sides, we apply Pythagoras theorem which states that:
[tex]Hyp^2 = Adj^2 + Opp^2[/tex]
Solving (1):
[tex]Hypotenuse = 13[/tex]
So, we have:
[tex]13^2 = 12^2 + x^2[/tex]
[tex]169 = 144 + x^2[/tex]
Make [tex]x^2[/tex] the subject
[tex]x^2 = 169 - 144[/tex]
[tex]x^2 = 25[/tex]
Take positive square root of both sides
[tex]x = \sqrt{25[/tex]
[tex]x = 5\ in[/tex]
Solving (2):
[tex]Hypotenuse = x[/tex]
So, we have:
[tex]x^2 = 4^2 + 3^2[/tex]
[tex]x^2 = 16 + 9[/tex]
[tex]x^2 = 25[/tex]
Take positive square root of both sides
[tex]x = \sqrt{25[/tex]
[tex]x = 5\ mi[/tex]
Solving (3):
[tex]Hypotenuse = 14.7[/tex]
So, we have:
[tex]14.7^2 = x^2 + 11.9^2[/tex]
[tex]216.09 = x^2 + 141.61[/tex]
Make [tex]x^2[/tex] the subject
[tex]x^2 = 216.09 - 141.61[/tex]
[tex]x^2 = 74.48[/tex]
Take positive square root of both sides
[tex]x = \sqrt{74.48[/tex]
[tex]x = 8.6\ km[/tex]
Solving (4):
[tex]Hypotenuse = 15.4[/tex]
So, we have:
[tex]15.4^2 = x^2 + 6.3^2[/tex]
[tex]237.16 = x^2 + 39.69[/tex]
Make [tex]x^2[/tex] the subject
[tex]x^2= 237.16 - 39.69[/tex]
[tex]x^2= 197.47[/tex]
Take positive square root of both sides
[tex]x= \sqrt{197.47[/tex]
[tex]x= 14.1\ mi[/tex]

2x + 1 =5
What does x=
Answer:
2
Step-by-step explanation:
2x + 1 =5
2x=4
x=2
First isolate the term containing x which is 2x.
Subtract 1 from both sides to get 2x = 4.
Since x is being multiplied by 2, divide both sides by 2 and we have x = 2.
What is the 72nd term of the arithmetic sequence {an}={1.4,5.5,9.6,13.7,...}
Answer:
292.5Step-by-step explanation:
Given the sequence 1.4,5.5,9.6,13.7,...
The nth term of am arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
From the given data;
a = 1.4
d = 5.5-1.4 = 9.6-5.5 = 4.1
n = 72 (since we are looking for the 72nd term)
Substitute;
T₇₂ = 1.4+(72-1)(4.1)
T₇₂ = 1.4+71(4.1)
T₇₂ = 1.4+291.1
T₇₂ = 292.5
Hence the 72nd term of the sequence is 292.5

Step-by-step explanation:
First, S must be 4, as if S was 5 the sum would be a 4 digit number.
T+N should be greater than 10 as we want to find the maximum.
Similarly, A+U must be greater than 10, making O equal to 9
We know that A+U-10 = T+N if T+N is less than 10 -- if T+N is greater than 10, A+U-10 = T+N - 10
Writing a quick python script that's not the cleanest nor most concise, I have

for t in range(0,10):
for n in range(0,10):
if (len({a,u,t,n}) == 4) & (4 not in {a,u,t,n}) & (9 not in {a,u,t,n}):
if (a+u >= 10):
if (t+n >= 10):
if ((a+u-10) == (t+n-10)):
sols.append(a+u-10)
sols_combos.append([a,u,t,n])
num_sols += 1
else:
if ((a+u-10) == (t+n)):
sols.append(a+u-10)
sols_combos.append([a,u,t,n])
num_sols += 1
list_max = [i for i, x in enumerate(sols) if x == max(sols)]
pd.Series(sols_combos).loc[list_max]
as my script.
the maximum I get for F is 5, and the solutions, in terms of A, U, T, and N are as follows:
[7, 8, 0, 5]
[7, 8, 2, 3]
[7, 8, 3, 2]
[7, 8, 5, 0]
[8, 7, 0, 5]
[8, 7, 2, 3]
[8, 7, 3, 2]
[8, 7, 5, 0]
This means that F is 5
Consider points A(2,3) and B(6,9). Find point C on the x-axis so AC + BC is a minimum. The point that minimizes AC + BC is C ( , ).
Answer:
the point C(x,0) = C(3,0) is the point where AC + BC is minimum.
Step-by-step explanation:
Solution:
This question is very simple to solve.
We need to find the x and y elements of point C, which is on the x-axis such that AC + BC = minimum.
So,
As, we have said that, point C is on the x-axis then, it means its y co ordinate will be equals to zero.
Now, we just need to find x co ordinate of the point C.
C (x, 0) as it is on the y -axis.
So, for that, we need to take the mirror image of point B. It means, its x co-ordinate will remain same but y co-ordinate will be negative.
So, our mirror image of B(6,9) = B'(6,-9)
Now, we have to join the points A and B'. Point C, which we are trying to find is the point where this line AB' intersects with x - axis.
So,
Slope of the line AB'
m = [tex]\frac{y1-y2}{x1-x2}[/tex]
m = [tex]\frac{3- - 9}{2 - 6}[/tex] = [tex]\frac{3+9}{2-6}[/tex]
m = [tex]\frac{12}{-4}[/tex] = -3
m = slope = -3
We also know that the equation of line:
y = mx + b
where b = y-intercept.
Now, we need to find the y - intercept of this line.
y = (-3) x + b
where y = -9 and x = 6
so,
-9 = (-3) (6) + b
b = -9 + 18
b = 9 = y - intercept.
SO,
y = mx + b
and For point C(x, 0) y = 0
0 = -3x + 9
Solve for x:
3x = 9
x = 3
Hence, the point C(x,0) = C(3,0) is the point where AC + BC is minimum.

y = 3x - 7
Is it linear or exponential
Answer:
Linear
Step-by-step explanation:
The equation y = 3x - 7 is a linear.
A linear equation represents a straight line on a graph, where the variables (in this case, x and y) have a linear relationship.
The equation has a constant coefficient (3) multiplying the variable (x), and a constant term (-7) added or subtracted.
An exponential equation involves variables in the exponent, such as
y = abˣ, where a and b are constants.
The variable x is in the exponent, indicating exponential growth or decay.
Since the equation y = 3x - 7 has a linear relationship and represents a straight line, it is classified as a linear equation.

Answer:
There are 3,628,800 different ways for the runners to finish.
Step-by-step explanation:
Arrangments of x elements:
The number of possible arrangments of x elements is given by the following formula:
[tex]A_{x} = x![/tex]
In this question:
10 different runners, which means that the number of different ways that there are for the runners to finish is an arrangment of 10 elements. So
[tex]A_{10} = 10! = 3628800[/tex]
There are 3,628,800 different ways for the runners to finish.
