Answer:
Step-by-step explanation:
A graph between the amount of time that backpacker hikes to the distance travelled is given .
- We need to find the constant of proportionality and the equation of the relationship .
According to the Question ,
- Where k is a constant . Now from the graph , when y is 5 x is also 5 . On substituting the numbers ,
Again the constant of proportionality is the slope of the line.
- Here the slope of the line is 1 and its y intercept is 0 . On using slope intercept form ,
O All real numbers is the range of the function
Answer:
Since both and , you can use a normal distribution to approximate the binomial distribution.
The mean is of 11.1 and the standard deviation is of 2.64.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
Using the normal distribution to approximate the binomial distribution.
This is possible if:
A survey of U.S. adults found that 37% have been to court. You randomly select 30 U.S.
This means that
Test if it is possible:
Since both and , you can use a normal distribution to approximate the binomial distribution.
Mean and standard deviation:
The mean is of 11.1 and the standard deviation is of 2.64.
Answer:
Andrea get for each scooter?
Step-by-step explanation:
Answer:
y=-1/2x+15/4
Step-by-step explanation:
transfer the equation into slope intercept form. subtract 4x from each side getting 8y=-4x+30 then divide by 8.
