Is it easier to graph an equation in y-intercept form or standard form? Explain.

Dafna1 [17]

Y-intercept form because it is more commonly used and easier to remember. The foundation of the y-intercept is easier to put in a graphing calculator also as it is already set to y=

The measure of C if a=6 and b=9.

kirill115 [55]

Answer:

$c=3\sqrt{13}$

Step-by-step explanation:

Pythagorean Theorem: In the right triangle the square of longer side is equal to the sum of the squares of other sides.

$c^2=a^2+b^2\\\\c^2=6^2+9^2\\\\c^2=36+81\\\\c^2=117\\\\c^2=3\times 3\times 13\\\\c=\sqrt{3\times 3\times 13}\\\\c=3\sqrt{13}$

Camp Ground A has an area of 300 square yards with a maximum capacity of 25 pup tents. Camp Ground B has an area of 480 square y

Damm [24]

Answer:

40 pup tents

Step-by-step explanation:

Since Ground A has area 300 and maximum capacity is 25 tents, so each tent would take up area of 300/25 = 12 sq yards.

Since Ground B's tents should occupy same area as Ground A's tents (12 sq. yards), the maximum capacity of this tent (480 sq yd) would be:

480/12 = 40 pup tents

This is the maximum capacity.

Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousan

ohaa [14]

Answer:

$P(\bar X\:>27.8\:thousand)=3.07\%$

Step-by-step explanation:

Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.

The standard deviation of the sample means is:

$\sigma_X=\frac{\sigma}{\sqrt{n} }$

$\implies \sigma_X=\frac{10.6}{\sqrt{50} }=1.4991$

The z value is $z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n}} }$

We plug in the values to get:

$z=\frac{27.8-25}{1.4991}=\frac{2.8}{1.4991}=1.87$

The area to the right of 1.87 is $1-0.96926=0.03074$ .

The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%
