The distance covered by a car traveling at a constant speed is directly proportional to the time spent traveling. If the car goes x=75 miles in y=2.5 hours, how far will it go in 7 hours?

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

Determine domain and range, largest open interval, and intervals which function is continuous.

Assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.
