Answer:
36/80 chance of landing on tails, or a 45% chance .
Answer:
Step-by-step explanation:
first we turn ur mixed number into an improper fraction
1 1/4 = 5/4
the reciprocal of 5/4 can be found by just flipping it....so the reciprocal is gonna be 4/5
so 1 1/4 subtracted from its reciprocal is :
4/5 - 5/4 =
16/20 - 25/20 =
- 9/20 <====
Answer:
The first one because it does not repeat the numbers
Step-by-step explanation:
Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
Answer: 4(5+2) or 4(2+5)
Step-by-step explanation:
8 = 2*2*2
20 = 2*2*5
4(5+2) = 20+8
