Answer:
The probability you will get a head at least once is 50%.
Step-by-step explanation:
Since the question is asking about the probability you will get, we can assume we’re answering based on theoretical probability. This type of probability is based on logic.
A coin always has two sides, one with head and the other with tails. So we can easily represent this as half and half. 1/2 as a fraction. 0.5 as a decimal. 50% as a percent. This means that P(H) will be equal to any one of these as they are all the same. The same can be said for the probability that a head does not appear, in other words, a tail appears. The reason being that the probability is split evenly between the two. This will again mean that P(T) will equal to any one of those.
So, A = 50% and B = 50%. The probability you will get a head at least once is 50%.
Answer:
10, 10, 0
Step-by-step explanation:
Square root 74 is 8.6 so to the nearest 10 is 10
Square root 53 is 7.2 so also 10
Square root 7 is 2.6 so 0
Answer:
"-2" is the same in all expressions, and it's just plus or minus. so let's ignore the "-2" and look only at the rest
+1 is the greatest then
so -2+1 is the greatest

Answer:
Step-by-step explanation:
Let red candy weighs r and blue candy weighs b
<u>Total weight is 7 pounds:</u>
<u>Red costs $1.5 per pound, blue costs $2 per pound and total cost is $12</u>
We have two equations.
<u>Solve by elimination, double the first equation and subtract the second equation from the first:</u>
- 2r + 2b = 14
- 1.5r + 2b = 12
<u>Subtract and solve for r:</u>
- 2r - 1.5r = 14 - 12
- 0.5r = 2
- r = 4
<u>Find b using the first equation:</u>
<u>The answer is:</u>
- Mike had 4 pounds of red and 3 pounds of blue candies.
