Answer:

25%

Step-by-step explanation:

1. You have a total of 1,200 students and a fraction of them did not wear their school colors, 300 students.

2. You would write the fraction \frac{300}{1200}.

3. After you divide or simpify  \frac{300}{1200} you get \frac{1}{4}.

4. To get a percent you multiply by 100, so \frac{1}{4} times 100 is equal to 25.

Answer:

<em>20%</em>

Step-by-step explanation:

<em>First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.</em>

To qualify for a police academy, candidates must score in the top 10% on a general abilities test. The test has a mean of 200 an
kolbaska11 [484]

Answer:

z = 1.28 < a - 200/20

And if we solve for a we got

a = 200 + 1.28 * 20 = 225.6

So the value of height that separates the bottom 90% of data from the top 10% is 225.6.  

Step-by-step explanation:

Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:

X ~ N (200,20)

For u = 200 and o = 20

For this case we can use the z score in order to solve this problem, given by this formula:

Z = x-u/o

For this part we want to find a value a, such that we satisfy this condition:

P (X > a) = 0.1 (a)

P (X < a) = 0.9 (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.9 of the area on the left and 0.1 of the area on the right it's z=1.28. On this case P(Z<1.28)=0.9 and P(z>1.28)=0.1

If we use condition (b) from previous we have this:

P ( X < a) = P (X-u/o < a - u/o) = 0.9

P (z < a-u/o) = 0.9

But we know which value of z satisfy the previous equation so then we can do this:

z = 1.28 < a - 200/20

And if we solve for a we got

a = 200 + 1.28 * 20 = 225.6

So the value of height that separates the bottom 90% of data from the top 10% is 225.6.

Farmer Kipp sold 25 horses for a total of $7500 in January and 25 horses for a total of $10500 in February. What is the average
insens350 [35]

Answer:

So Average Price of horse is $360

Step-by-step explanation:

Given:

25 horses sold in January for $ 2500

25 horses sold in February for $10500

TO find:

Average price of horse = ?

Solution:

Average price is usually found out by adding all the values and dividing by its total no of values

Now in our case

Total Horse = 25 + 25

                     = 50

Total Money = $7500 + $10500

                      = $18000

Average Price =\frac{total price}{total horses}

Average Price =\frac{18000}{50}

                                =$360

So Average Price of horse is $360
