Answer:
It will take 1.6 hours for the two trains to be 336 miles apart.
Step by step explanation:
Given that:
Speed of eastbound train = 95 miles per hour
Speed of westbound train = 115 miles per hour
Combined speed = 95+115 = 210 miles
Distance = 336 miles
Hence,
It will take 1.6 hours for the two trains to be 336 miles apart.
34 x 17 (round the 2 numbers)
30 x 20
600
Also, 34 x 17 = 578, which rounds to 600
The answer is 34 and 17
The answer to the question would be 2 3/8
Hope this helps.
Answer:
16 = a
Step-by-step explanation:
6 = a/4 +2
Subtract 2 from each side
6-2 = a/4 +2-2
4 = a/4
Multiply each side by 4
4*4 = a/4*4
16 = a
Variance to be zero: only one condition that ll the values or measurements of variable must be same.
variance = summation of (x - a)²
where is x is each data value in the collection
a is average of all data in the collection.
Summation of squares is zero implies that each square is zero.
each x -a must be 0.
