Roland is picking out a snack. He has an apple, a pear, a banana, and an orange to choose from. Roland is going to pick one at random and wants to know what the chance that he will pick a bananna? Identify the action, the sample space, and the event.

Answers

Answer 1

Answer: Since there are 4 options and only 1 banana, there is a 1/4 chance he will pick a banana. I'm not sure what you mean by the last few questions? I think the sample space is an apple, pear, banana, or an orange. And the event is banana?

Answer 2

Answer: Ω = 4 set all equally probable events
aplle, pear,banana, orange
A = 1 random event favorable
banana

$P(A) = (A)/(omega) = (1)/(4)$

Roland choose once and has one chance in four that will draw the coveted banana. Therefore, the probability of this event is 1/4

Answer 1/4

What is the value of x?6([-3]-x)-2x=14

Answers

Multiply 6 (-3-x) to get -18-6x.
So now we have -18-6x-2x=14.
Simplify that to -18-8x=14.
Add 18 on both sides.
Now we have -8x=14+18.
-8x=32
Divide by -8 on both sides.
We get x=-4.

What percent of 4 hours is 8 seconds?

Answers

Answer:

0.055% of 4 hours is 8 seconds.

Step-by-step explanation:

Use conversion:

1 hour = 3600 seconds

We have to find the percent of 4 hours to 8 seconds.

4 hours = 14400 seconds

then;

$\text{Percent} = (8)/(14400) * 100 \approx 0.055\%$

Therefore, 0.055 percent of 4 hours is 8 seconds.

so 4 hours
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600seconds
4 hours=3600 seconds times 4=14400seconds

so 8 out of 14400
8/14400=2/3600=1/1800
percent means parts out of100 so
x%=x/100
the reatios are equal to
1/1800=x/100
mulitply both sides by 100
100/1800=x
1/18=x
divide out
0.055555555=x
round
0.06%

Which is the simplified form of this expression?

(2x+3) (x-6)-2x^2+3x+30

Answers

-6x + 12

To find this answer, follow these steps:

First, multiply 2x + 3 and x - 6 using either the FOIL method or the box method. This should get you the answer of 2x^2 - 9x - 18

This should now replace the 2x + 3 and x - 6

So with that, you should have this currently:

2x^2 - 9x - 18 - 2x^2 + 3x + 30

Now, combine like terms:

The 2x^2 cancels each other out. After that, combine -9x and 3x to get -6x. Then -18 and 30.

This should leave you with the final answer of -6x + 12

Hope this helps!
