100%. This is because 8/8=1. Just imagine if you had eight blueberries and you ate eight of those, how many would be left? zero, right? because you ate 100% of them. :)

Use the given data to find the minimum sample size required to estimate the population proportion. margin of error: 0.0080.008

nadezda [96]

Formula for the Minimum Sample size $n=(\frac{z}{E})^2\hat{p}\hat{q}$

The least biased estimate for p and q is 1/2.

$z_{\frac{\alpha }{2}}=z_{{0.01}{2}}=2.58$

Thus

$n=(\frac{2.58}{0.08})^2*0.5*0.5$

$n=260.015$

$n\approx260$

Help please, try to explain it in steps for me if u can't that's fine, ty!

Iteru [2.4K]

Answer:

B

Step-by-step explanation:

We are given that Expression One is:

$2\cdot 10^x$

And Expression Two is:

$4\cdot 10^{x+y}$

We are given that the value of Expression Two is 20,000 times greater than the value of Expression One. And we want to find the value of <em>y.</em> In other words:

$4\cdot 10^{x+y}=20000(2\cdot 10^x)$

We can divide both sides by four:

$10^{x+y}=10000\cdot 10^x$

Recall that:

$x^a\cdot x^b=x^{a+b}$

Therefore:

$10^x\cdot 10^y=10000\cdot 10^x$

Divide both sides by 10ˣ:

$10^y=10000$

Solve for <em>y: </em>

<em /> $\displaystyle y = \log_{10}10000 = 4$ <em />

Our answer is B.

John wants to build a corral next to his barn. He has 300 feet of fencing to enclose three sides of his rectangular yard.

Mandarinka [93]

Let's first define the variables:
x = width
300 - 2x = long
The area will be:
A = (x) * (300 - 2x)
A = 300x - 2x²
We look for the maximum area, for this, we derive:
A '= 300 - 4x
We match zero:
0 = 300 - 4x
x = 300/4 = 75
Therefore, the width is:
x = 75 feet
The length is:
300 - 2x = 300 - 2 (75) = 300-150
150 feet
Answer:
Part A:
The maximum area will be:
A = (150) * (75) = 11250 square feet
Part B:
The dimensions are:
Length = 150 feet
width = 75 feet
