Answer:
Step-by-step explanation:
First transpose 3x
you are having 3x+4y=7
by transposing you will get
4y=-3x+7
divide by 4 throughout by making y subject of the formula you will find your equation as y=mx+c.
Two conditions under which we can assume that the sample means follow a normal distribution are as follows:
1). If the sample size is large enough, n greater than or equals 30, the sampling distribution is approximately normal regardless of the shape of the population.
2). In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.

It was hard to figure this put but I'll just a take an educated guess and say that the answer is 10%.
Answer:
x= 27.71281 = 16√3
y= 13.85641 = 8√3
Step-by-step explanation:
hope it helps :)
Answer: y = 0.5cos(x), choice A
The parent function y = cos(x) follows this same basic pattern of the curve shown, but it starts off at (0,1) as its highest point. This graph has its highest point to be half as high, so we multiply by 1/2 or 0.5
