Answer:
its either C or D
Step-by-step explanation:
there are 2 possible outcomes for getting either heads or tails so if we divided 150 by 2 we get 75, so about 75 times you could get tails.
so maybe it is D, but im not sure
Answer:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 gives the next term.
.
Answer:
A) y+5=2(x+2)
Step-by-step explanation:
In an arithmetic sequence d represent the common difference.
The formula to find the general term of an arithmetic sequence is,

Where
= nth term and
= First term.
Given,
. Therefore,


Next step is to subtract the above equations so that we can eliminate a1 and get the value of d. Hence,
4d - 8d = 24 - 40
-4d = - 16
Divide each sides by - 16.
d = 4
So, d = 4.
Hope this helps yoi!.
Answer:
sin 60° = 1/2 √3
B. √3/2
Step-by-step explanation:
sin 0° = 0
sin 30° = 1/2
sin 45° = 1/2 √2
sin 60° = 1/2 √3
sin 90° = 1
