9 - (-2) = __ a0 <br><br> solve the equation

Math troubles :/ greatly appreciated if you can help

RUDIKE [14]

Answer:

$V=523.33$

Step-by-step explanation:

$V=\frac{4\pi r^3}{3}$

$V=\frac{4\pi 5^3}{3}$

$V=\frac{500\pi }{3}$

$V=\frac{500*3.14 }{3}$

$V=\frac{1570 }{3}$

$V=523.33$

A food store owner wants to determine the type of products customers prefer to buy. The owner surveyed 40 customers on a day whe

lora16 [44]

There is not a fixed boundary line as to when the sample size should be considered appropriately large but the rule of thumb is a sample size larger than 30 is sufficient enough to assume that the data is normally distributed. Since the sample size in this case is 40, we can consider it appropriately large and use Normal Distribution to deduce the results.

Sample Size = n = 40
Proportion of customer who prefer organic food= p = 40% = 0.40
Confidence Level = 95%
Z score at the confidence Level = z = 1.96

Margin of Error for the population proportion is calculated as:

$M.E=+-z \sqrt{ \frac{p(1-p)}{n} }$

Using the values, we get:

$M.E=+-1.96 \sqrt{ \frac{0.4*0.6}{40} }=+-0.152$

Thus, the option B gives the correct answer.
As the sample size is appropriately large, the margin of error is ±0.152.

I NEED HELP LIKE NOW PLS!<br> I'll give you brainliest answer if you can help me ((:

The first word of the question is cut out of the picture, so we don't exactly know what the assignment is. But we can see that the graph of f(x) will do something weird when x=-3, because the denominator will be zero, and division by zero doesn't even have a definition or meaning. Just for fun, you should go ahead and calculate the numerator when x=-3, and that totally blows your mind, because the numerator is zero too. So you've got. f(-3)= 0/0 , and I can pretty much guarantee that you won't be able to plot that point anywhere on the graph. (I'm pretty sure that f(-3) is actually going to turn out to be -13, but even if I'm correct, you probably haven't learned that little calculus trick yet, so don't worry about it. As far as you're concerned, f(-3) is 0/0, and can't be plotted.)
