Answer:
D. $53.76.
Step-by-step explanation:
20% = 0.20 as a decimal.
Price before Sales Tax = 64 - 0.20*64
= $51.20
Adding 5% sales tax we get
52.20 + 0.05*51.20
= $53.76 (answer).
Answer:
<u>∠DFA = 82°</u>
Step-by-step explanation:
According the property of inscribed angles and arcs, the angle is half of the arc length.
Solving :
- ∠CFB = 1/2 x ∡CB
- ∠CFB = 1/2 x 164°
- ∠CFB = 82°
- ∠CFB = ∠DFA (Vertically Opposite Angles)
- <u>∠DFA = 82°</u>
When zero is added to or subtracted to a number, the number is not affected.
Let us say T= probability of head turning up = 1/2 in one toss
H = probability of a tail turning up = 1/2 in one toss
Then P (56 heads or more) =
1/2^100 [ C(100,56) + C(100,57) + C(100,58) + ....
C(100,98) + C(100,99) + C(100,100) ]
where C(N, R) = N ! / [ (N - R)! R! ] number of occurrances of R formed from
N tosses.
Well consecutive means in a row, or one number after the other (for ex. 1,2,3,4). And for this equation it's asking for 4 consecutive numbers of which the sum is -26. To get this you just need to go on a calculator and just try some consecutive numbers, you'll get it pretty quickly. The answer is -5,-6,-7,-8. The sum of those numbers is -26.
Hope this helps!
