Forty percent of the homes constructed in the Quail Creek area include a security system. Three homes are selected at random: Wh

suter [353]

Answer: 0.064

Step-by-step explanation:

Binomial probability formula :-

$P(X)=^nC_x \ p^x\ (1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials, n is total number of trials and p is the probability of getting succes in each trial.

Given : The proportion of the homes constructed in the Quail Creek area include a security system : $p=0.40$

Now, if three homes are selected at random, then the probability all three of the selected homes have a security system is given by :-

$P(3)=^3C_3 \ (0.40)^3\ (1-0.40)^{3-3}\\\\=(0.40)^3=0.064$

Hence, the probability all three of the selected homes have a security system = 0.064

The map shows the location of the houses of Dan, Joe, Lee, and Roy:

Crazy boy [7]

Answer:

<em>Roy has a house in the same quadrant as the Community Center</em>

Step-by-step explanation:

<u>Rectangular Coordinates</u>

The coordinate grid shown in the image below contains the locations of the houses of Dan, Joe, Lee, and Roy.

It has also been marked the four quadrants I, II, III, and IV.

Note that Dan is in quadrant I, Joe is in quadrant II, Lee is in quadrant III, and Roy is in quadrant IV.

The Community Center (CC) is also in quadrant IV, thus the answer is:

Roy has a house in the same quadrant as the Community Center

I been working on this for 2 and a half hours and its do at 11:59 pm but i want it done now. The question says , A stack of nest

mylen [45]

Answer:

h= 0.25c +4

Step-by-step explanation:

➀ Define variables

Assuming that you are asking for the equation representing the height of the stack, let's start by letting the height of the stack be h inches and the number of cups be c.

➁ Find the increase in height with every additional cup

If an additional cup is stacked on the first cup, the height increment is 0.25 inches. When 2 cups are added, the height increment is 2(0.25)= 0.5 inches. Thus the expression for the increase in height is 0.25c, where c is the number of cups as we have already defined in step 1.

➂ Find the total height of the stack

Since the height of the first cup remains constant at 4 inches tall, the total height of the stack can be represented by the equation:

h= 0.25c +4
