172/387 = 4/t
Let t = time to travel 387 miles
172t = 4(387)
172t = 1548
t = 1548/172
t = 9
Answer: 9 hours
Since there are 2 black sixes and 2 black eights in a typical deck of 52 cards, the probability of choosing one of those 4 out of 52 is 4/52 or 1/13.
rise over run
(-1,2) (2,2)
2-2/2-(-1)
2-2/2+1 equals 0/3
or alternatively
2-2/-1 - 2 which would be -0/3.
Whichever point is the first helps determine this alot
rise/run=rise over run= y2 - y1/ x2 - x1
Answer:
0.92 and 1.25 respectively
Step-by-step explanation:
0.92 and 1.25 respectively
first the mean of each value which is 9.7 and 9.8 respectively
standard deviation = square root of the mean deviation of each value
then deduct the mean from each element
and square each value and add them together. not you should square each deviation value before you add them
at last divide the result by the number of frequency and find it's square root
