Step-by-step answer:
Given:
Distance = 2464 miles
downwind time = 14 hours
upwind time = 16 hours
Solution:
downwind speed = 2464 / 14 = 176 mph
upwind speed = 2464 / 16 = 154 mph
Average speed = still air speed
= (176+154)/2
= 330/2
= 165 mph
Time required
= 2464 / 165
= 14.933 hours
= 14 hours 56 minutes.
The answer is the distributive property
Answer:
C. 3
Step-by-step explanation:
In arithmetic, the range of a set of data is the difference between the largest and smallest values. However, in descriptive statistics, this concept of range has a more complex meaning. The range is the size of the smallest interval which contains all the data and provides an indication of statistical dispersion. It is measured in the same units as the data.
2 - (-1) = 3
6 - 3 = 3
etc...
3xy
<span>y(3y)/3xy + y(xy)/3xy + (y+1)(3x)/3xy </span>
<span>NOW since all of the fractions have a denominator of 3xy, drop the denominators and solve using the numerators. </span>
<span>y(3y) + y(xy) + (y+1)(3x) </span>
<span>3y^2 + xy^2 + 3xy +3x </span>
<span>cannot simplify further.</span>
Answer:
0.368
Step-by-step explanation:
Number of red marbles= 3
Number of blue marbles= 4
Number of green marbles= 7
Total number of marbles= 3+4+7= 14
Let the first ball is taken out to be red
P(R)=
than again a second ball is drawn, number of balls left= 14-1=13
Number of red= 2
P(R)=
Total probability=+
Total probability= 0.368
Hence, the correct answer is 0.368
