Answer:
20
Step-by-step explanation:
We can simplify 10/2 = 5
5 = n/4
Multiply each side by 4
5*4 = n/4*4
20 =n
Answer: n = 20
Explanation: To solve for n in this proportion,
we simply use the means-extremes property.
Since 10/2 = n/4, we know that the product of the extremes,
(10)(4), equals the product of the means, (2)(n).
So we know that (10)(4) or 40 equals (2)(n) or 2n.
Dividing both sides by 2, 20 = n.

In response to a gss question in 2006 about the number of hours spent per day watching television, the responses by the fifteen subjects who identified themselves as Buddhist were 0, 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 4, 4, and 5. For these fifteen subjects, the mean number of hours spent per day watching television is 1.93 hours. What is the standard error of this mean estimate?
Answers
Answer:
Standard error = 0.4
Step-by-step explanation:
Step 1
We find the Standard Deviation
The formula = √(x - mean)/n - 1
n = 15
Mean = 1.93 hours
= √(0- 1.93)² + (0-1.93)² +(0- 1.93)²+( 0- 1.93)²+ (1- 1.93)² + (1- 1.93)² +(1 - 1.93)² +(2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + ( 2 - 1.93)² +(4 - 1.93)² +(4 - 1.93)² + (5 - 1.93)²/15 - 1
= √(3.737777776 + 3.737777776 + 3.737777776 + 0.871111111 +0.871111111 + 0.871111111 + 0.004444444445+ 0.004444444445 + 0.004444444445 + 0.004444444445 + 0.004444444445 + 1.137777778 + 4.271111112 + 4.271111112 + 9.404444446)/15 - 1
= √2.352380952
= 1.533747356
Step 2
We find the standard error
The formula = Standard Deviation/√n
Standard deviation = 1.533747356
n = 15
= 1.533747356/√15
= 1.533747356 /3.87298334621
= 0.39601186447
Approximately = 0.4
Therefore, the standard error is 0.4

Gi dont understand how to find Which ordered pair is a solution of the equation? y=8x+3
Answers
Answer:
(1, 11 ) is a solution
Step-by-step explanation:
To obtain a solution, choose any value of x, substitute into the equation and evaluate for y, that is
choose x = 1, then
y = 8(1) + 3 = 8 + 3 = 11
Thus (1, 11 ) is a solution
choose x = - 2 , then
y = 8(- 2) + 3 = - 16 + 3 = - 13
Thus (- 2, - 13 ) is also a solution
Lets go over the solutions.
Let's start with (1, 11). After substituting x = 1 and y = 11, it results in the equation 11 = 11, which is a true statement. Hence, this is one solution.
Now, let's look at (-1 -5). After substituting x = -1 and y = -5, it results in the equation -5 = -5, which is also a true statement. So, this being said, (-1, -5) would also be a solution.
Hence, our two solutions are:
Both [tex](1, 11)[/tex] and [tex](-1, -5)[/tex].

Step-by-step explanation:
If you use the distributive property, you get 14 + 35x = 3x + 14. Then, subtract 3x from both sides to get 14+32x=14. Subtract 14 from both sides to get 32x= 0. These aren't equivalent, so there are no real solutions. Hope this helps!

1. The line through A and B has a slope = _____ and y-intercept = _____
2. Write an equation for this line. ________
Answers
Answer:
1. slope= 1/2; y intercept=3
2. y= 1/2x+3
Step-by-step explanation:
The slope is equal to the y value of b minus the y value of a OVER the x value of b minus the x value of b. This simplifies to 1/2.
If the slope is 1/2, you can see that for every 1 that the line rises, its x value increases by 2. Since you know the when the x value is 2, the y value is 4, decreasing the x value by 2 (making it 0) would make the y value 3.
