(3n + 1)(n-5)
Hope this helped
This cannot be the question. You definitely read this wrong. If p(notA)= .75 then P(not A) = .75...
If the question is find P(A), however, then the use the compliment rule
1- P(not A) = P(A)
1-.75 = .25
Answer:
21 and 26 totaling 47sticks
Step-by-step explanation:
Th number of sticks form an arithmetic progression
1, 6, 11, 16...
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = 1
d is the common difference
d = 6-1 = 11-6 = 5
n is the number of terms
The next two terms are the fifth and sixth term
T5 = 1+(5-1)5
T5 = 1+4(5)
T5 = 1+20
T5 = 21
T6 = 1+(6-1)5
T6 = 1+5(5)
T6 = 1+25
T6 = 26
Hence the number of sticks needed in the next two piles are 21 and 26 totaling 47sticks
Answer:
It is already simplified
Step-by-step explanation:
0.09375 in decimals
80 because 160 divided by 2 is 80 so 2 x 80
