8,6 i think i’m not sure though
X - 14 = y
x + y = 58
x is the amount you sold
y is the amount your friend sold
Distance<-------------300--------------><-------------------x----------------->
⊕---------------------------------⊕--------------------------------------⊕ Express Freight Overtaking point
Speed 55 speed 30
Let x be the distance travelled by Freight until the point of overtaking
Time = Distance/Speed, then:
Time (freight) = Distance (fright)/Speed (freight) And
Time (Express) = Distance (Express)/Speed (Express).
Now plug in the relative number:
Time (freight) = x/30 and Time (express) = (x+300)/55. But note that both times are equal, then:
x/30 = (x+300)/55 OR (x÷30 = (x+300)÷55) [Answer C]
Now let's find the distance x. Cross multiplication;
55x= 30(300+x) →55x = 9,000 + 30x
55x - 30x = 9,000 → 25x = 9,000 and x = 9,000/25 = 360 miles
Time needed for Freight to travel 360 m = 360/30= 12 Hours
Time needed for Express to travel (300+360) m = 660/55= 12 Hours
As you see, it's the same time of 12 hours
Don't forget that Distance = Speed x time or time = Distance/Speed, etc.
A) The experimental probability is 1/1 = 1
b) The experimental probability is 2/6 = 1/3
c) The experimental probability is 4/12 = 1/3
d) The theoretical probability is 1/6
Answer:
72.5
Step-by-step explanation:
5, 12, 15, 23, 42, 51, 55, 66, 68
42 = median
Q1 median = 21
Q2 median = 93.5
93.5 - 21 = 72.5
Hope this helped!!!
