Step-by-step explanation:
OP=11.2
m<Q= 42⁰
m<R=48⁰
The tools used are....
I have used the property of Pythagoras Theorm to get the length of side QP, I have also used the property of inverse function of sin to get the measure of angle Q and the property of sum of angles of triangle to get measure of angle of R
If a set of exam scores forms a symmetrical distribution, then the student mean scores is the median and the mode too.
<h3>What is a Symmetrical distribution?</h3>
A symmetrical distribution by definition is the situation which occurs when the values of variables appear at regular frequencies and is characterized by the mean, median, and mode all occuring at the same point in most cases.
Graphically, symmetrical distributions may appear as a normal distribution (i.e., bell curve).

Using the assumed values, the volume of the cone is 
<h3>How to determine the volume of the cone?</h3>
The volume of a cone is calculated using:
The parameters are not given.
So, we use the following assumed values
Radius, r = 5
Height, h =10
Using the assumed values, we have:
Evaluate the product
Hence, using the assumed values, the volume of the cone is

Given that two digit numbers are used and one digit is drawn randomly.
Sample space = {10,11,...99}
n(S) = 90
32 is only one number favorable
Hence P(32) = 1/90
----------------------------
Odd numbers are exactly 45.
Hence prob (odd number) = 45/90 = 1/2
-------------------------------------
Multiples of 5 are 10,15,.....95
There are exactly 18 numbers.
Hence P(a multiple of 5) = 18/90 =1/5
Have an amazing day! <3
