<u>Answer:</u>
<u>Step-by-step explanation:</u>
Distance traveled by a car between two cities = 1/6 distance
Time taken to travel between the two cities = 3/5 hours
Therefore, to find how much of the distance the car can travel in 1 hour, we need to divide the given distance by the given time to get:
(
) ÷ (
)
Change the later fraction to its reciprocal to solve:
× 
=
Therefore, in one hour, the car can travel 5/18 of the distance.
Answer:1442
Step-by-step explanation:
Given,
Mean is,
Standard deviation,
,
Margin of error(E) = 0.54,
For 98% level of confidence,
Thus, the sample size would be,
Sketch a graph so you can find the vertex and determine if the parabola is horizontal or vertical. When i graph (-2,4) and then y=6, I find the middle is (-2,5) so that will be the vertex. The distance to the vertex is -1 so 4p=-4.
My formula is (x-h)^2=4p(y-k), now just plug in numbers. You should end up with (x+2)^2=-4(y-5).
Some instructors want you to write (y-k)=1/(4p)(x-h)^2 which is the same thing, so check to see which one you should be using.
Answer:
16 miles
Step-by-step explanation:
We can write the ratio of miles:hours as 80:5 using the given information. Because we want to find the distance of 1 hour, we can divide the ratio by 5 (because 5/5 is 1, and we want 1 on the "right side") which gets us 16:1. This means that the motorcycle traveled 16 miles in one hour. Hope this helps!
The median for a set of numbers would be the one that appears closest to the middle of the set.
For the set 4, 8, 10, 5, 9, in order to find the median, we must first sort them numerically.
4, 5, 8, 9, 10
Now, which of these 5 numbers is the closest to the middle?
The answer to that would be 8, since it is actually the number in the middle.
The median number for the numbers 4, 8, 10, 5, 9 is 8.
Hope that helped =)
