In your Pre-Calc class 60% of the students have brown hair, 30% have brown eyes and 10% have both brown hair and brown eyes. A s

maria [59]

Probability of the students having brown hair = 0.6

Probability of the students having brown eyes = 0.3

Probability of the students having both brown hair and brown eyes = 0.1

Step-by-step explanation:

Step 1 :

Given,

Percentage of the students having brown hair = 60%

Percentage of the students having brown eyes = 30%

Percentage of the students having both brown hair and brown eyes = 10%

We need to obtain the probability of each separately, when a student is chosen randomly

Step 2 :

The probability of each event happening given its percentage, can be obtained by dividing the corresponding percentage by 100.

Hence we have,

Probability of the students who have brown hair = $\frac{60}{100}$ = 0.6

Probability of the students who have brown eyes = $\frac{30}{100}$ = 0.3

Probability of the students who has both brown hair and eyes = $\frac{10}{100}$ = 0.1

Step 3 :

Answer :

Probability of the students who have brown hair = 0.6

Probability of the students who have brown eyes = 0.3

Probability of the students who has both brown hair and eyes = 0.1

Describe how to round 678 to the nearest hundred.

Vika [28.1K]

The nearest hundred will be in the hundredth place

For example, 2000

2 is in the thousands, followed by hundreds, ten, ones

to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.

So in this case 678 will equal 700

Example: if it were 644, then it would be 600

hope this helps

Show your work and explain how you can determine which is a better deal:

densk [106]

Answer: 10 ounces for $2.40

Step-by-step explanation: The trick behind these problems, always divide. 2.40/10ounces is $0.24. 2.08/8ounces is $0.26. Better deal, therefore smaller answer of the 2, because it's cheaper.
