. Osteen has 32 marbles in his collection. 18 of his marbles are red, four are blue, and the rest are
nalin [4]

Answer: B

Explanation:  

32 marbles in total.

18 red marbles

4 blue marbles

10 green marbles.

You are asked what part of Osteen's marbles are red?

Probability = number of possible outcomes/total number of out outcomes.

P(Red) = 18/32 = 9/16

Both, 18 and 32 are divisible by 2 which gives 9/16. Since 9/16 cannot be reduced any further, we live it as it is. If you wanted to plug this into a calculator that would give 0.5625 which is 56.25% of Osteen's marbles are red.

P(Blue) = 4/32 = 1/8. 1/8 = 0.125 which 12.5% of his marbles are blue.

P(Green) = 10/32 = 5/16. 5/16= 0.3125 which 31.25 of his marbles are green. When you add 0.5625 + 0.125 + 0.3125 = 1 which is 100%. All probabilities add up to 1.

Hope this elaborate explanation helps.

Please help me out with this :)
Misha Larkins [42]

Answer:

x = 1

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 12 when x = - 2, then

k = \frac{y}{x} = \frac{12}{-2} = - 6, thus

y = - 6x ← equation of variation

When y = - 6, then

- 6 = - 6x ( divide both sides by - 6 )

x = 1

 2. Therefore, to solve this problem you must follow the proccedure that is shown below:

 3. You must sum the amount of water that  Ashley and Claire drank before the practice. Then, you have:

 1/2 pints=0.5 pints (Ashley)
 0.7 pints (Claire)

 x=0.5 pints+0.7 pints
 x=1.2 pints
</span><span>
 How many pints of water did Ashley and Claire drink combined?
</span><span>
 The answer is: 1.2 pints or 1 1/5 pints

Mason is working two summer jobs, making $20 per hour lifeguarding and making $10 per hour landscaping. In a given week, he can
alexgriva [62]

Answer:

x = 4\\y = 9 hours

Step-by-step explanation:

Given -

x represents the number of hours lifeguarding and y represents the number of hours landscaping

x+ y = 13 -----Eq ( 1 )

and

20 * x + 10 * y = 170 -----Eq ( 2 )

Substituting the value of x = 13-y in equation 2, we get -

20* (13 - y) + 10 y = 170

260 - 20 y + 10 y = 170\\10y = 90\\y = 9

x = 13-9 = 4
