14) A projectile is fired from a cliff 300 feet above the water at an inclination of 45° to the horizontal, with a
muzzle velocity of 180 feet per second. The height h of the projectile above the water is given by
-32x2
h(x)
+ X + 300, where x is the horizontal distance of the projectile from the base of the cliff. Find
(180)
the maximum height of the projectile.

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?

Which fraction is equal to 1hole and 2/5? a.3/5 b.75 c.57 d.73

Ahypothesis is: a the average squared deviations about the mean of a distribution of values b) an empirically testable statement that is an unproven supposition developed in order to explain phenomena a statement that asserts the status quo; that is, any change from what has been c) thought to be true is due to random sampling order da statement that is the opposite of the null hypothesis e) the error made by rejecting the null hypothesis when it is true
