C. How can you use the area of the square to find the side length?

Kruka [31]

Answer:

Step-by-step explanation:

Since squares are the same length on each side, whatever one side is, if you square it, it will give you the area of the square. To find the length of one side, you need to do the inverse: find the square root of the area.

for example: if you have a square that is 3x3, the are is 3², or 9. Now, in order to find the length of one side, you need to do √9, which gives you 3.

A waiter's weekly salary can be modeled by the equation y = 0.2x + 300, where x is the amount spent by the customers in dollars

Answer:

x=500$

y=0.2×500+300

y=100+300

y=400

I let 500$=x because they were spent by the customers

Construct a confidence interval of the population proportion at the given level of confidence. x = 125, n = 250, 90 % confidence

madam [21]

Answer: 90% confidence interval would be (0.448, 0.552).

Step-by-step explanation:

Since we have given that

x = 125

n = 250

So, $\hat{p}=\dfrac{x}{n}=\dfrac{125}{250}=0.5$

We need to find the 90% confidence interval.

so, z = 1.64

So, interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.5\pm 1.64\sqrt{\dfrac{0.5\times 0.5}{250}}\\\\=0.5\pm 0.0519\\\\=(0.5-0.0519,0.5+0.0519)\\\\=(0.448,0.552)$
