Answer:
Y-intercept is (0, -13)
X-intercept is at (13/5, 0)
Step-by-step explanation:
When it's in this form, y = mx + b, you automatically know what the y-intercept is (b).
So the y-intercept is (0, -13)
To algebraically find this, you'd plug in a 0 for x, since the y intercept is when it crosses the y-axis, which is located at x = 0.
To find the x intercept, you'd do the opposite of the y-intercept, which is plugging in a 0 for y and solving for x. The x-axis is located at y = 0.
0 = 5x - 13
13 = 5x
x = 13/5
The x-intercept is at (13/5, 0)
I hope this helped!
Answer:
b = 3/4
Step-by-step explanation:
Hi!!!
You want the value of B. To get that, we have to divide both sides by 16:


Thus the answer to your question is
.
<u>Check:</u>
3/4 * 16 = 3 * 4 = 12.
12 = 12
So we are correct!!!
Answer:
Mean: 4
Median : 4
Mode: 1, 2, 3, 4, 5, 6, 7
Step-by-step explanation:
Measure of center is:
Mean: Average
Median: Middle number
Mode: Often number
Mean: Add all number then divide by the total number in data set.
1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
28/7 = 4
Median: Middle number
1,2,3,4,5,6,7
Mode: most often number
1,2,3,4,5,6,7

B / 24 because I had to do this whole assignment . I got 100 on it . Non of the others make since if u do the math
Answer:
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 29.5
Standard deviation r = 5.2
Number of samples n = 59
Confidence interval = 90%
z-value (at 90% confidence) = 1.645
Substituting the values we have;
29.5+/-1.645(5.2/√59)
29.5+/-1.645(0.676982337100)
29.5+/-1.113635944529
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
