Using it's concept, it is found that there is a 0.45 = 45% experimental probability of the coin landing on tails.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, 9 out of 20 trials resulted in tails, hence the experimental probability is given by:
p = 9/20 = 0.45 = 45%.

Answer:
45 and 135
Step-by-step explanation:
If angles, with measurements a and b, are supplementary, then a and b have sum 180 degrees.
So we have the following equation so far:
a+b=180
Now we also have that one angle has a measurement that is 1/3 the value of the one.
So we also have 3a=b which means we are letting the angle whose measurement be a have 1/3 the value of b.
So lets plug the second equation into first giving us:
a+3a=180
Add like terms:
4a=180
Divide both sides by 4:
a=180/4
a=45
So b=3a=3(45)=135.
So the angles in question have measurement s 45 and 135.

This for the first one
x=5
y=46
z=88
This for second one
x=y
so x=45
y=45
z=11.1
This for the third one
x=60
y=60
z=4.2
This for the fourth one
x=60
y=16
z=16
Step-by-step explanation:
Right now 8 represents 8 hundred.
after multiplied by 1,000, the 8 will represent 8 hundred thousand. <span />
