Answer:
0.31311311131111....
Step-by-step explanation:
We need to tell a number which when adds to 0.4 makes it a Irrational Number . We know that ,
<u>Rational</u><u> number</u><u> </u><u>:</u><u>-</u> The number in the form of p/q where p and q are integers and q is not equal to zero is called a Rational number .
<u>Irrational</u><u> number</u><u> </u><u>:</u><u>-</u> Non terminating and non repeating decimals are called irrational number .
Recall the property that :-
<u>Property</u><u> </u><u>:</u><u>-</u><u> </u> Sum of a Rational Number and a Irrational number is Irrational .
So basically here we can add any Irrational number to 0.4 to make it Irrational . One Irrational number is ,
So when we add this to 0.4 , the result will be Irrational . That is ,
Answer:
EC/BC = DE/AB
Step-by-step explanation:
There are multiple answers for this, but this should work as well. EC is proportional to BC, and AB is proportional to DE, so one answer is: EC/BC = DE/AB
N is equal to 11 because 5-2n=17 would be changed into 2n-5=17 because it would be -17 if it was the original problem so that is why
Question:
Alfie tossed a paper cup in the air 150 times and recorded the side it landed on.
Right side up = 60 Upside down = 53 Side = 37
If Alfie tosses the paper cup 100 more times what is the expected number of times the cup will land on its side?
Answer:
The expected number of times the cup will land on its side is 25 times
Step-by-step explanation:
Given



Required
First, we calculate the probability of landing on side



Next, we calculate the expected value; E(x) using:

When tossed 100 more times:
n = 100 and P(x) = P(Side) = 0.247
So:


--- approximated
<em>Hence, it is expected that it will land on its side 25 times</em>
Answer:
77
Step-by-step explanation:
mean is also known as the average
to find the average you add up every data point and divide by number of data points.
74 + 75 + 80 + 76 + 75 + 81 + 78 = 539
539 / 7 = 77
