Answer:

0.073

Step-by-step explanation:

Given information:

Probability of ethnic minorities (P) = 0.33

Number of Trials (n) = 10

Required successes (x) = 6 or more

To find the answer for this problem we will employ the Binomial Probability equation

b(x; n, P) = nCx * P^x * (1-P)^n^-^x

To find the answer for 6 or more success we first calculate the following values

1) 6 success

2) 7 success

3) 8 success

4) 9 success

5) 10 success

so

b6 = 10C6 * (0.33)^6 * (1-0.33)^1^0^-^6 = 0.0547

b7 = 10C7 * (0.33)^7 * (1-0.33)^1^0^-^7 = 0.0154

b8 = 10C8 * (0.33)^8 * (1-0.33)^1^0^-^8 = 2.841 * 10^-^3

b9 = 10C9 * (0.33)^9 * (1-0.33)^1^0^-^9 = 3.110 * 10^-^4

b10 = 10C10 * (0.33)^10 * (1-0.33)^1^0^-^10 = 1.532 * 10^-^5

Adding all these values we get the probabilities we get 0.0732

I have $100. I spent $40 on a prize and $45 on food. How do I figure out what % is purchase is from the original amount I had?
Paladinen [302]
You could say that you spent (purchased) 85% of the money that you had.

You spent a total of $85.

If you create the fraction 85/100, that is the same as saying you spent 85% of the money.

Human blood has an approximate pH of 7.3. Which substance is more basic than human blood?
ratelena [41]


so, 7 is neutral anything past 7 is considered basic.

answer: <em>a water and ammonia solution with a pH of 11 (very basic).</em>

<em />any number under 7 is acidic and of course there are different degrees of acidic just like there are different degrees of basicity.   

______________________________________________________________

- stomach's digestive juices, would be considered very acidic

-apple juice is also acidic but not as acidic  like stomach juices.

- grape juice, is becoming less acidic.

Hopefully this helped and good luck.

Korey runs every 3rd day and swims every 4th day. If he runs and swims today, how many days will it be before Korey runs and swi
hichkok12 [17]

Answer: 12 days

Step-by-step explanation:

Based on the question, we have to list the multiples of 3 and 4. This will be:

3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40.

The lowest common multiple is 12.

It will take 12 days before Korey runs and swims again on the same day.
