I answered a similar problem yesterday.
In three coin tosses there are 8 possible outcomes:
H H H
H H T
H T H
T H H
T T H
T H T
H T T
T T T
Of those results, four out of the eight have at least 2 tails and so the probability is (4/8) or50%
If you need the probability of getting EXACTLY 2 tails then the probability is (3/8) or .375
Hi!
16^2 x 4/7 = 1,462,784
1,462,784 is a number that can be written as a fraction (1,462,784/1) therefore it is rational.
The answer is yes, because it can be written as a fraction.
Hope this helps! :)

Answer:
148º
Step-by-step explanation:
Use the information given:
- The measure of a straight line is 180º. So angle PST=180-(2R+8)
- Since ST and QR are parallel, angle PST=angle PQR. Now, angle PQR=180-(2R+8)
- The sum of a triangle's interior angles is 180º. So 40+180-2R-8+R=180º.
- Combine like terms, 212-R=180
- Subtract, -R=-32
- Convert to positive, R=32º
With R=32º, we can find angle QST and PQR. Angle QST=2(32)+8=64+8=72º. So angle PQR=180º-72º=108º. The sum of a quadrilateral's interior angles is 360º:
- 32º+72º+108º+STR=360º
- Combine like terms, 212º+STR=360º
- Subtract, STR=148º
do what is in the parenthesis first and you multiply first. 3x2 is 6. 6+3 is 9. 9-9 = 0
I think the answer is 0
Answer
98 seconds
Step by step explanation
The reason being is that .5 would be millisecond and 5 will round up making the answer be 98 seconds
