Answer:
165
Step-by-step explanation:
formula is
nCr = n!/(r!(n−r)!)
r= 8 = number of choosing objects from the set
n = 11 = total number of objects in the set
C(n,r)=C(11,8)
=11!/(8!(11−8)!)
! means factorial
factorial means to multiply by decreasing positive numbers.
For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320
=11!/8!×3!
= 165

Answer:
You replace y with f(x)
Step-by-step explanation:
- Function is a relation between two sets of numbers, with every element
in the first set has only one corresponding element in the second set
- The first set is called the domain of the function (input)
- The second set is called the range of the function (output)
- If the first set is set X and the second set is set of Y, then each value
of x has only one value of y and x is the input and y is the output
- Function notation is the way to write a function f(x) = y, where f(x)
represents the values of y
∵ y = 2x + 1
∵ f(x) = y
- Replace y by f(x)
∴ f(x) = 2x + 1
* <em>You replace y with f(x)</em>

Answer: 300 dollars off
Step-by-step explanation:
522.54 / 0.55 = 287.4
Which is less than 300 dollars off
To convert mixed fractions to improper fractions:
a b/c=(ac+b)/c so we have:
43/10+127/30+37/15 now making all terms have a common denominator of 30
(43/10)(3/3)+(127/30)(1/1)+(37/15)(2/2)
129/30+127/30+74/30
(129+127+74)/30
330/30
11 acres
Now
11a(25b/a)=275 bags of fertilizer.
