Three coins, a quarter, nickel and penny, are tossed. What is the probability that all three coins will show heads. Show in an organized list.

Answers

Answer 1
Answer: Since all of the coins only have 2 sides, heads or tails, the equation will be: 1/2 * 1/2 * 1/2  = Answer.  Multiply the probability of getting a head for 1 coin by 3 since there are 3 coins. The probability of having all three heads will be 1/8.

0.4(2x-9)-0.6(4x+5)=

Answers

Answer:

From what I can comprehend I believe the answer is 3.2x + -4

Step-by-step explanation:

0.4(2x-9) = 0.8x - 9

0.8x - 9 - 0.6(4x+5)=

0.8x - 9 + 2.4x+5

0.8+2.4 = 3.2x

-9 + 5 = -4

3.2x + -4

Why cant i find what is equivelent to 50/100

Answers


I can't imagine.  All you have to do is pick any old number, divide the
top and bottom of the fraction by it, and you'll have a new fraction that's
equivalent to  50/100 .  And if the number you pick is  2,  5,  10, or  25,
then the new fraction will even have whole numbers on top and bottom.

You can even pick any old number, multiply the top and bottom of the
fraction by it, and you'll have a new fraction that's equivalent to  50/100 .

Can't imagine what's so hard about that.

Ben's Bicycle Helmets makes bicycle helmets at a cost of 3000 + 12x dollars per month toproduce x helmets. They sell the helmets for $21 each.
1. Determine the cost to produce 500 helmets.

Answers

Answer:

Cost to produce 500 helmets will be $9000.

Step-by-step explanation:

Expression that represents the cost of the bicycle helmets is given as

C = 3000 + 12x

where x = number of helmets produced.

1. Cost of production of 500 helmets can be calculated by putting x = 500 in the expression.

C = 3000 + 12×500

   = 3000 + 6000

   = $9000

Therefore, cost to produce 500 helmets will be $9000.

Answer:

$9000

Step-by-step explanation:

3000+12x

x = 500

3000 + (12*500)

3000+6000

$9000

A number cube is rolled. What is the probability of rolling 2, 3, or 5?PLEASE HELP!!!!!

Answers

Since there are six sides of a cube, or a die, the probability of rolling a 2 is 1/6. In the same way, the probability of getting a 3 is 1/6 and getting a 5 is also 1/6. Hence, the probability of rolling 2, 3 or 5 is the sum of all the probabilities each number can be rolled. That is P = 1/6 + 1/6 + 1/6 which is 3/6 or 50%. There is a 50% chance that the number rolled is 2, 3, or 5. 
The probability of rolling any one of these numbers is 1/6, which converted in to percentage is 16.6%. The probability of rolling any two of these numbers is 2/6 which converted in to percentage is 33.3%. The probability of rolling all 3 of these numbers is 3/6, which converted in to a percentage is 50%. Hope it helps:).
