A parking lot 200 meters wide; 1 centimeter: 25 meters

1 answer:

5 0

Well all you have to do is 200 divided by 25, which is 8 so that would be your answer, unless there is another part to this question.

Answer:

Step-by-step explanation:

The coefficient of variation CV is given by the following formula:

$CV = \frac{\sigma}{\mu}$

In which $\sigma$ is the standard deviation and $\mu$ is the mean.

Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds

This means that $\sigma = 16, \mu = 200$ .

So his coefficient of variation is

$CV = \frac{16}{200} = 0.08$

Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.

This means that $\sigma = 10, \mu = 125$

So her coefficient of variation is

$CV = \frac{10}{125} = 0.08$

They have the same coefficient of variation, so the correct answer is.

The x-coordinate of the intersection point of Line B D and Line C E is StartFraction 2 (a + c) Over 3 EndFraction. y = (StartFra

ddd [48]

Answer:

y = 2b/3

Step-by-step explanation:

The x-coordinate of the intersection point of Line B D and Line C E is at $\frac{2(a+c)}{3}$ . Given that:

$y=\frac{b}{a-2c}x -\frac{2bc}{a-2c} \\\\The\ y\ coordinate\ can\ be \ gotten\ by\ substituting\ the \ value\ of\ x\ and\ simplifying.\\ Substituting\ x:\\\\y=\frac{b}{a-2c}(\frac{2(a+c)}{3} ) -\frac{2bc}{a-2c}$

$Simplyfing\ the\ parenthesis\\y=\frac{2b(a+c)}{3(a-2c)} -\frac{2bc}{a-2c}\\\\y=\frac{2ab+2bc}{3(a-2c)} -\frac{2bc}{a-2c}\\\\Simplyfying\ using\ LCF\\y=\frac{2ab+2bc-6bc}{3(a-2c)}\\\\y=\frac{2ab-4bc}{3(a-2c)}\\\\Factorizing:\\\\y=\frac{2b(a-2c)}{3(a-2c)}\\\\y=\frac{2b}{3}$

The y-coordinate of the intersection point of Line B D and Line C E is at $\frac{2b}{3}$ .
