Probability helps us to know the chances of an event occurring. The probability that all four pennies will be tails is (1/16).
Probability helps us to know the chances of an event occurring.
The probability of a penny getting a tail is 0.5 or (1/2), therefore, the probability of four penny getting a tail can be written as,
Hence, the probability that all four pennies will be tails is (1/16).

20v - 7
Answer:
To calculate the actual yield of iron in moles, we need to use the molar mass of iron (Fe) and the given mass of iron produced.
The molar mass of iron (Fe) is approximately 55.845 g/mol.
Given:
Amount of Fe2O3 = 0.288 mol
Mass of Fe produced = 18.1 g
To find the moles of Fe produced, we can use the molar mass of Fe:
moles of Fe = mass of Fe / molar mass of Fe
moles of Fe = 18.1 g / 55.845 g/mol
moles of Fe ≈ 0.324 mol
Therefore, the actual yield of iron in moles is approximately 0.324 mol.
Answer:
y-9=-1(x+3)
Step-by-step explanation:
The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation
