For the probability of one thing or another, you add the two probabilities together. In that case, the probability of getting 3 or 4 is (2/3) + (1/8) = 19/24
Answer:
$22.20
Step-by-step explanation:
We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.
Let's set up our equation by making 13.32 into a fraction.
13.32/x
We will represent the present's actual cost with the letter x.
13.32/x = 3/5
We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a <em>fraction </em>of the present's cost, not the whole cost.
We solve this by doing cross multiplication. Multiply the 13.32 by the 5.
13.32 x 5 = 66.6
Next we divide 66.6 by 3 to get 22.2
66.6/3 = 22.2
This gives us our final answer of $22.20. This means that the cost of the original present was $22.20
Answer: x=4, x=-6
Step-by-step explanation:
set the equation equal to 0. solve for the x using the x method.
Answer:
51 people
Step-by-step explanation:
The graph show the result of 150 people. If we look at the graph we can see that 34% completed college. To find out how many of the 150 people completed college we simply multiply 0.34 by 150. We got 0.34 from the 34% that completed college. When we multiply them together we get 51 people.
