Answer:
See below in bold.
Step-by-step explanation:
For the fair coin Prob(head) = 1/2 and Prob(Tail) = 1/2.
For the biased coin it is Prob(head) = 2/3 and Prob(Tail) = 1/3.
a) Prob(2 heads) = 1/2 * 2/3 = 1/3.
b) Prob(2 tails) = 1/2 * 1/3 = 1/6.
c) Prob(1 head ) = Prob(H T or T H) = 1/2 * 1/3 + 1/2 * 2/3) = 1/6+1/3 = 1/2.
d) Prob (at least one head) = prob (HH or TH or HT) = 1/3 + 1/2 =<em> </em>5/6.
Hi there!
The question sounds really complex, but the mathematical operations behind it is figuratively simple. Here, we are told to find 19 (18.7 rounded up is 19) percent of 1,000. To do this, we can set up a proportion to model the whole scenario.
Now, just solve for x by cross multiplying and simplifying.
Therefore,
190 people out of 1,000 people leave out pertinent information on their IRS forms. Hope this helped and have a terrific day!
Answer:
1) x= 43
2) x= 54
Step-by-step explanation:
you add the two angles given, then take that answer and subtract it from 180!
i hope this helped!!
Answer:
p < -32
Step-by-step explanation:
<em>Given:</em> p/-8 + 9 > 13
<em>Rewrite:</em> + 9 > 13
<em>Subtract 9 from both sides:</em> > 4
<em>Move the negative (it is a fraction): </em> > 4
<em>Multiply both sides by 8:</em> -p > 32
<em>Times by -1 (-p -> -1p): </em>p > -32
<em>Flip the sign (multiplied by a negative): </em>p < -32
Hope this helps, have a nice day :D
Answer:
Aplha=105
Step-by-step explanation:
The perpendicular looks like double the base hence that angle is 30 and the other triangle have equal perpendicular and base, that angle is 45. So alpha+30+45=180, alpha=105
