2^0 is 1. The reason for this because zero is indeterminate (like how 0 * 0 is). In fact, any number to the power of 0 is 1 because of this.
Hope this helps!
Answer:
48 students
Step-by-step explanation:
multpily 75 by 64%. 0.64*75= 48/
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

If you only have 3 point problems you have a total of 3*30=90 points, since the test has 100 points you need 10 extra points, so 10 of those 3 point questions have to be changed to 4 point questions.
So 20 3-point questions and 10 4-point questions.
