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)
Answer: Choice B)
The relation is a function because there are no vertical lines that can be drawn on the graph that pass through more than one point.
This graph passes the vertical line test. Any input (x) leads to one and only one output (y). An example of a graph failing the vertical line test would be a graph that is a sideways parabola.
Answer:
f(x)= -2x-3, im so sorry if this is wrong
Step-by-step explanation:
to translate it left you have to add 2
If you had a grid handy, that would help my explanation a lot. First mark 0,0 on your grid. Then draw a line where x = -2 (this should just be a vertical line that intersects (-2,0)). Notice how 0,0 is 2 units away from that line? In order to show a reflection, add 2 units on the other side of the x=-2 line. Mark that dot. Make sure the y value is the same. The x value should be -4.
FIRST REFLECTION: (-4,0)
Onto the second reflection! This is over the y-axis, but since the first reflection is already on the y-axis it wouldn't change.
Final answer: (-4,0)
The answer is 2 fishing method and divide both sides by 6
