True because of positive correlation.
1. <A= sin a/c
= sin 26/31
=sin 0.8387=57degree
<A= 57degree
2.<B= cos a/c
= cos 26/31
= cos 0.8387=33degree
<B = 33degree
3.<em><u><</u></em><em><u>C</u></em><em><u>=</u></em><em><u>9</u></em><em><u>0</u></em><em><u> </u></em><em><u>degree</u></em> cause it already gave us the sign of perpendicular sign
4. B=(c^2 - a^2)square root
=(31^2-26^2)square root
=(961-676)square root
=(285)square root
B=

The approximate original price of the car is $23032
<h3>How to determine the original price?</h3>
The given parameters are:
Rate, r = 8%
Price at 4 years old = 16,500
An exponential function is represented as:
y = a(1 - r)^x
Where a represents the initial value
This gives
y = a(1 - 8%)^x
Evaluate
y = a(0.92)^x
At 4 years old, we have:
16500 = a(0.92)^4
Divide both sides by (0.92)^4
a = 23032
Hence, the approximate original price of the car is $23032

Hi there,
I’m attaching the same image with more information on the graph.
The 4th mark (the middle dashed line) is marking the mean (70).
The 3rd and the 5th are marking the mean less/plus 1 deviation.
So, 70.5 is the 5th mark.
Taking this into account:
The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%
The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%
Good Luck!
