Step-by-step explanation:
Answer:
<u>390.4 in.²</u>
Step-by-step explanation:
- Area of sector = πr² x θ/360
- Area = 22/7 x 64 x 70/360
- Area = 11 x 10 x 32 x 1/9
- Area = 320 x 11/9
- Area = 320 x 1.22
- Area = <u>390.4 in.²</u>
The probability of randomly getting first a red marble and then a blue marble is:
P = 0.083
<h3>
How to find the probability?</h3>
There are:
- 3 blue marbles
- 2 red marbles
- 4 yellow marbles.
For a total of 9 marbles.
The probability of getting a red marble is equal to the quotient between the number of red marbles and the total, so:
P(red) = 2/9
Then the probability of getting a blue marble is equal to the quotient between the number of blue marbles and the total, but because we already took one marble, now the total is 8.
P(blue) = 3/8
The joint probability is given by the product:
P = (2/9)*(3/8) = 0.083

Just plug in your x and solve like normal
-4< 4(1) - 8 < 12
-4< -4 < 12
now solve both sides by moving the -4 out by adding + 4 to all sides
0 < x < 16
when read this says 0 is less than X and X is less than positive 16.
the other 3 are solved the same.
