Answer:
Step-by-step explanation:
First, write an equation. 55x+40=190.
X represents the hours the electrician works. The 55 represents the $55 that she charges for each hour she works. The +40 for the $40 that was the price just to come to your house. The 190 is the total cost. Now, solve that equation.
55x+40=190
55x=150
x=2.72727272...
So the answer is 2.727 hours. It can be rounded as needed or turned into a decimal, 2 8/11.
We have been given that the total number of households she surveyed = 150
Now, out of 150, 35 of them said they turn out the lights each year on Halloween.
Now, in order to find the percentage of households that turn out the lights each year on Halloween, we will divide 35 by 150 and then multiply the result with 10.
Thus, we the required percentage is given by
Therefore, to nearest percent is 23%.
Hence, the estimated population proportion of households that turn out the lights each year on Halloween is 23%
The probability that both cards are kings is 4/52 times 3/51. This is 12/6256, or 1/221.
