Answer:
<h2>
3,654 different ways.</h2>
Step-by-step explanation:
If there are 30 students in a class with natasha in the class and natasha is to select four leaders in the class of which she is already part of the selection, this means there are 3 more leaders needed to be selected among the remaining 29 students (natasha being an exception).
Using the combination formula since we are selecting and combination has to do with selection, If r object are to selected from n pool of objects, this can be done in nCr number of ways.
nCr = n!/(n-r)!r!
Sinca natasha is to select 3 more leaders from the remaining 29students, this can be done in 29C3 number of ways.
29C3 = 29!/(29-3)!3!
29C3 = 29!/(26!)!3!
29C3 = 29*28*27*26!/26!3*2
29C3 = 29*28*27/6
29C3 = 3,654 different ways.
This means that there are 3,654 different ways to select the 4 leaders so that natasha is one of the leaders
Answer:
Step-by-step explanation:
5x + 1 is a SUM.
3y is a TERM.
9(5x + 1) is a PRODUCT.
9 is a FACTOR of 9(5x + 1).
5x + 1
---------- is a QUOTIENT.
3y
5 is the COEFFICIENT of x.
Answer:
if he sells 12 every 8 months, supposing the trend continues, in 34 months he’ll sell...
12(properties) = 8 months
12/8 = 1 month
1 month = 1.5(properties)
2 months = 3 properties
(since 1.5 properties is unrealistic, but it helps in the math, to find for one month)
so for 34 months he’ll sell...
1.5*34 = 51 properties
If he flipped the coin 100 times and got 50 heads, then the answer would be 0.5 (since 50/100 = 1/2 = 0.5). I think you might be mixing theoretical probability with empirical probability.
In this case, he got 28 heads out of 75 flips
so 28/75 = 0.373333... where the 3's repeat forever
This rounds to 0.37
That's why the answer is actually choice A
