Answer:
a) P(x=5) = 0.2456
b) P(x≥6) = 0.3526
c) P(x<4) = 0.1887
Step-by-step explanation:
We can model this as a binomial experiment, with sample size n=10 and p=0.49.
To calculate the probability of having k subjects with very little confidence in the sample of 10, we solve:
a) We have to calculate P(x=5).
For a binomial variable with n=10 and p=0.49, this can be calculated as:
b) We have to calculate P(x≥6). This can be calculated as:
c) We have to calculate P(x<4). That is:
This is the concept of geometry, the congruence statements that can be evaluated from the parallel figure is:
DH=HF
EH=HG
EF=DG
DE=FG
hence;
Hence ΔDEF is congruent to ΔDGF and ΔEFG is congruent to ΔEGD by Side-side-side (SSS) postulate
Same as before, since 180° is π, how much is 30° in radians?
Answer:
I belive I might be c not completely sure but pretty positive
Answer:
Answer choices A, C, and D.
Step-by-step explanation:
If you assume that the 70 degrees is one of the base angles, then the other base angle is also 70 and the third angle is 40 degrees (thus answers C and D). However, if it is the top angle, the other two angles must both be 55 degrees (thus answer A). Hope this helps, and PM me with questions!
