A random sample of size 150 taken from a population yields a proportion equal to 0.35.(a)Determine if the sample size is large enough so that the sampling distribution may be approximated by a normal distribution.(b)Produce the margin of error associated with 90% confidence.(c)Would the margin of error increase or decrease if we increase our confidence to 99%

step-by-step explanation:

x-3y=4

step-by-step e

sounds & other waves originate from any vibrating object

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
