Answer:
The probability that at least one of the first two groupmates you meet has studied more than one semester of statistics = 0.55 (1 - 0.45).
Step-by-step explanation:
Probability of those who have never taken a statistics class = 0.1 (10%)
Probability of those who have taken only one semester of a statistics class = 0.35 (35%)
Therefore, the probability of those who have taken two or more semesters of statistics = 0.55 or 55% (1 - 0.35 - 0.1).
The speed of the faster cyclist will be 30 miles/hour.
<em><u>Explanation</u></em>
One cyclist is 3 times as fast as the other.
Lets assume that the speed of the slower cyclist is miles/hour.
So, the <u>speed of the faster cyclist</u> will be: miles/hour.
They start riding toward each other at the same time and meet 2 hours later.
We know that,
So, the <u>distance traveled by slower cyclist</u> in 2 hours miles and the <u>distance traveled by faster cyclist</u> miles.
Given that, they were 80 miles apart at the starting. So, the equation will be.....
So, the speed of the faster cyclist will be: (3×10)= 30 miles/hour.
For the first question, divide 200 by the seconds. You would get the answer 9.07. This answer is rounded to the nearest hundredth.
The second question, you would convert that to feet by using the units 1 meter = 3.28084.
If you converted it, the answer woudl be 29.75722 ft/second
Answer : R=1500−(60⋅t)
Explanation:
Total distance walked = 1500 meters.
Dakota's rate is 60 meters per minute.
The equation for distance walked over time = r⋅t .
Therefore the distance walked over time =
60 ⋅ t
The equation for distance remaining (let's call it R is 1500 −( 60 ⋅ t ). so the remaining distance to walk after a time t can be written as. "R = 1500 − ( 60 ⋅ t )
The product can be rewritten as
.. a^(1/4)*b^(1/6)
