-5n+26 because it goes down by 5 each time so -5n then dofferance is 26
X=1
Just pluck in the 1 into x and there’s is the answer
Answer:
okay if you gte the app photo math it will solve all of your math problems and will give you the solution
Step-by-step explanation:
1. given
2. corresponding parts theorem
- segments AB and DB are similar
and segments BC and BE are also similar. lastly the circle at angles C and E indicate that they are congruent
3. SSA similarly theorem
AB and BC are similar and BC and BE are similar and angle C and E are congruent. also the triangles are not congruent in length so that makes them similar.
i apologize if i am incorrect i like just learned this. have a great day and good luck on your studies
Answer:
0.17189
0.3504
Step-by-step explanation:
For a fair coin ; p = 0.5
1 - p = 0.5
P(x < 4) = p(x = 0) + p(x =1) + p(x = 2) + p(x = 3)
Recall:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a calculator to save time:
P(x <4) = 0.00098 + 0.00977 + 0.04395 + 0.11719
P(x < 4) = 0.17189
For a unfair coin :
p = 0.3 ; 1 - p = 1 - 0. 3 = 0.7
P(x ≥ 4) = p(x=4)+p(x =5)+p(x=6)+p(x=7)+p(x=8)+p(x=9) +P(x=10)
Recall:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a calculator to save time:
P(x ≥4) = 0.3504
