A farmer wishes to enclose a rectangular pasture with 1200 ft of fence. He needs to divide this rectangle into two smaller recta

Minchanka [31]

Answer: $60,000 ft^2$

Step-by-step explanation:

Given

total of 1200 ft of fence is available

Suppose rectangular pasture has following dimension as shown in figure.

total perimeter

$P=4a+3b$

$1200=4a+3b$

$4a=1200-3b$

$a=300-\frac{3}{4}b$

Area of rectangle is

$A=2a\times b$

$A=2(300-\frac{3}{4}b)b$

$A=2[300 b-\frac{3}{4}b^2]$

For maximum area, differentiate A w.r.t b

$\frac{\mathrm{d} A}{\mathrm{d} b}=300-\frac{3}{2}b=0$

$300=\frac{3}{2}b$

$b=200 ft$

so $a=300-150=150\ ft$

so area is

$A=2\times 150\times 200$

$A=60,000 ft^2$

A random sample is selected from a population with mean = 100 and standard deviation = 10. Determine the mean and standard devia

jenyasd209 [6]

The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be $N(100,10/\sqrt{41} ), N(100,10/\sqrt{130} )$ .

<h3>What is the distribution of the sample mean for large samples?</h3>

Suppose X has a distribution with mean $\mu$ and standard deviation $\sigma,$ then,

the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to $\sigma/\sqrt{n}$

Symbolically, we write it as:

$X \sim N(\mu, \sigma) \implies \overline{X} \sim N(\mu,\sigma/\sqrt{n} )$

A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.

The mean and standard deviation of the x sampling distribution for each of the following sample sizes.

If N=41

$X \sim N(100, 10) \implies \overline{X} \sim N(100,10/\sqrt{41} )$

If N=130

$X \sim N(100, 10) \implies \overline{X} \sim N(100,10/\sqrt{130} )$

20 PTS & BRAINLIEST TO CORRECT ANSWER!!!!

ELEN [110]

For the equation y - x < 0,y < xThe shaded portion will be under the dashed line joining points (-2, -2) and (3, 3).
for the equation x - 1 > 0,x > 1The shaded portion will be to the right of the dashed line joining points (1, 5) and (1, -3).
The portion affected by the two shadings will be the portion common to the right of the dashed line joining points (1, 5) and (1, -3) and under the dashed line joining points (-2, -2) and (3, 3).Therefore the correct answer is option c.
