### How to find the points where the image cross x axis

The **image **of the **parabolic lens **crosses the x axis at the points

(-8, 0) and (4, 0)

To find the points where the **graph **of the **function **crosses the x axis we need to find the values of x that make f(x) equal to **zero**

hence we have that

f(x) = 1/4 (x + 8) (x - 4)

0 = 1/4 (x + 8) (x - 4)

x + 8 = 0

x = -8

OR

x - 4 = 0

x = 4

hence we can say that the image of the parabolic lens crosses the x axis at the points (-8, 0) and (4, 0)

sample of 10 apartments advertised in the localnewspaper is $580.

Assume that the standard deviation is$90. Find a 95% confidence

interval for the mean monthly rentfor unfurnished one bedroom

apartments available for rent in thiscommunity.

**Answer: **

**Step-by-step explanation:**

**Confidence interval for population mean is given by :-**

, where = Sample mean

z* = critical z-value.

= Population standard deviation.

n= Sample size.

Let x be the denotes the monthly rent for unfurnished one bedroom apartments available for rent in this community.

As per given , we have

n= 10

Critical value for 95% confidence : z* = 1.96

**So the 95% confidence interval becomes,**

**Hence, a 95% confidence interval for the mean monthly rent for unfurnished one bedroom apartments available for rent in this community= **
