) Using the point estimate of p obtained from the prelimenary sample of 50 helmets, how many helmets must be tested to be 95% confidence that the error in estimating the true value of p is less than 0.02

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

d.) yes, because the volume of the cone is greater than the volume of the sphere
