Answer:
30 I'm guessing you mean add them.
Step-by-step explanation:
16+14=30
Answer:
No
Step-by-step explanation:
To find out if 2 is a solution, replace all the x's with 2.
4(2 - 1) - 3(2 - 2) =8
4(1) - 3(0) = 8
4 - 0 = 8
4 = 8
Nope! False! 2 is not a solution.
Answer:-3
Step-by-step explanation:
its just adding and subtracting
The correct option is: A. 80 cm³
Explanation
Diameter of the coin,
cm.
So, the radius,
cm.
As the coin is circular, so..
Area of each circular surface,
cm²
Now for finding the amount of plastic for making each coin, we will find the Volume of each coin first.
As the thickness (
) of the coin is 0.5 cm, so Volume of each coin,

As you need to make a batch of 50 coins, so the total volume of 50 coins
[Rounded up to the nearest multiple of 10 cm³]
So, the amount of plastic you will need for making a batch of 50 coins is 80 cubic centimeter.
Answer:
$3
Step-by-step explanation:
Flipping two fair coins :
Sample space :
{TH, HT, TT, HH}
Atleast one head = 12
If not = - 24
Probability of atleast one head = 3/4
If not ; probability of 2 tails = 1/4
Hence,
X ______12 ______ -24
P(x) ___0.75 ______0.25
Expected value for of gamble E(x) :
Σx * p(x) = (12 * 0.75) + (-24 * 0.25)
E(x) = 9 - 6
E(x) = 3
Expected value of gamble = $3
