Explanation:
The likelihood of receiving tails on one coin toss multiplied by the number of coin tosses gives the expected number of tails after six tosses. The predicted value is therefore 1/2.6, or 3.
Explanation:
There is a 1 in 6 probability that each dice will have a 6 on top. The die has six sides, which is the explanation. The outcome of a previous dice roll has no bearing on the likelihood that a 6 will appear for each die. These probabilities are independent, in other words. Therefore, the sum of the individual probabilities is the likelihood of tossing three sixes.
Explanation:
Black and blue pens are 7 to 28 or 7:28 in ratio. Divide both sides by 7 to get the lowest terms (1:4).
Explanation:
By aligning the numbers vertically with the decimal and adding, we may obtain the sum of two decimal numbers. The decimal will be lowered into the solution and lined up there. When adding the numbers in this issue when they are vertically aligned with the decimal, we begin by adding 7 and 4, which results in 11, and 1 is carried over to the subsequent column. The gets carried over one more after we add 7,5,1, and 2. Finally, we add 1 to 1, 0 to 0, and 0 to 1. When we move the decimal point such that it aligns with the solution, we discover that the product of 0.77 and 0.54 is 1.31.
Explanation:
The cost of the dishwasher = $450
15% discount amount = 450‣15/100 = $67.5
The discounted price = 450 – 67.5 = $382.5
20% additional discount amount on lowest price = 382.5‣20/100 = $76.5
So, the final discounted price = 382.5 – 76.5 = $306.0049
Explanation:
The diagonal distance between the top of his head and the base of the shadow can be calculated using the Pythagorean theorem.
Explanation:
We must divide the number of voters by the total number of registered voters in order to determine the overall turnout at each of the three polling places.
.
Number of total voters = 945 + 860 + 1210 = 3015
Number of total registered voters = 1270 + 1050 + 1440 = 3760
Percentage turnout over all three polling stations = 3015‣100/3760 = 80.19%
Checking the answers, we round 80.19 to the nearest whole number: 80%
