Answer:
B. 32°
Step-by-step explanation:
Since two of the sides are 10 in length, then we can infer that ∠A and ∠C are congruent. So, both equal 74°. You add 74 + 74 + x = 180, x would equal 32°.
3*7-6
21-6=15
15 is the answer
Answer:
Step-by-step explanation:
Given
Success
Failure
Consecutive trials until S happens
Number of trials
For every possible outcome, the last 3 must be SSS. So, we have:
The only possibility here is:
because 3 trials implies that all outcomes must be S.
The only possibility here is:
because 4 trials implies that the first outcome must be F
The possibilities are:
because 5 trials implies that the first and the second outcomes must be FS or SF.
The possibilities are:
because 6 trials implies that the first three outcomes are: FFF, SSF and SFF
The possibilities are:
because 7 trials implies that the first three outcomes are: FFFF, FSSF and SSFF and FFSF (similar to (e))
It is BA I think but I’ll have to check
The answer is 8 because you have 3 /4
