Answer:
The measure of arc EF = 146°
Step-by-step explanation:
From the figure we can see two circles with same center.
From the figure itself we get measure of arc AB is same as measure of arc EF, measure of arc Ac is same as measure of arc ED and measure of arc BC is same as arc FD.
The measure of arc AB = 146°
Therefore the measure of arc EF = 146°
Answer:
If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will <u>increase</u>.
Step-by-step explanation:
We have been given an incomplete statement. We are supposed to complete the given statement.
If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will:
We know that when confidence level decreases from a value to a lower value, then the confidence interval for the mean decreases.
When confidence level increases from a value to a higher value, then the confidence interval for the mean increases.
When we will increase the confidence level from 90% to 99%, the width of the confidence interval for the mean will also increase, so it will become wider.
Therefore, the correct word for our given statement is increase.
In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)
I believe 5 different ways. The options being two packs of 9-one pack of 9 and 3 packs of 3- 1 pack of 9, 2 packs of 3 and 3 singles- one pack of 9, one pack of 3, and 6 singles- and then one pack of 9 and 9 singles.
Hope this helped!
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
-------------------------------------
2x + y = -3 <em>subtract 2x from both sides</em>
y = -2x - 3
-2y = 6 + 4x
-2y = 4x + 6 <em>divide both sides by (-2)</em>
y = -2x - 3
We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions
x ∈ R
y = -2x - 3
