Answer:
3x+4=40
Step-by-step explanation:
Lets take "x" as the number of students who went on the trip last year
It says "3 times" the number of seventh grade students that went on the trip last year so we know that x will be multiplied by 3
It also says 4 more than so we know that 3x+4 is gonna be part of the equation
If 40 students went on this years trip then 3x+4=40
Answer:
And the density function is given by:
And the cumulative distribution function is given by:
And we want the following probability:
And we can use the complement rule and we got:
Step-by-step explanation:
Let X the random variable that represent the driving distance and we know that the distribution for X is given by:
And the density function is given by:
And the cumulative distribution function is given by:
And we want the following probability:
And we can use the complement rule and we got:
And that would be the final answer for this case.
Answer:
The gear ratio of the bike = 3:1
Step-by-step explanation:
Question:
A gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket. If a bike has 36 teeth on the front sprocket and 12 teeth on the rear sprocket, what is the gear ratio for the bike?
Given:
Number of teeth on the front sprocket = 36
Number of teeth on the rear sprocket = 12
To find the gear ratio for the bike.
Solution:
The gear ratio of a bike is the ratio of the number of teeth on the front sprocket and the number of teeth on the rear sprocket.
Thus, the gear ratio can be given as:
⇒
Reducing to simple fraction by dividing the numerator and denominator by their GCF.
⇒
⇒
Thus the gear ratio can be given = 3:1
