Step-by-step explanation:
Both of the numbers are negative and adding them will give you -9.
Answer: the number of presents that she has left to purchase is 6
Step-by-step explanation:
Let x represent the total number of presents that she has to purchase.
She bought three presents and says that she has 30% of her shopping finished. This means that she has finished (1/3 × x) = x/3 shopping. This is equivalent to 3 presents. Therefore,
x/3 = 3
x = 3×3 =9
She had 9 shopping to do
The number of shopping left will be total shopping that she has to do minus the shopping that she has done. It becomes
9 - 3 = 6
Answer:
The Answer is 0,133484. The same number as
or
Step-by-step explanation:
If the probability of an event occurring is <em>p</em>, then the probability of an event not occurring is <em>1-p</em>. Therefore if Lester plays one number, then the probability of that number not winning is 1-
or 1-0.25, which is
or 0.75
Two or more events are independent if the occurrence of one does not affect the probability of occurrence of the other. In Lester's game, the probability of a number winning or not winning does not affect the probability of the same number winning or not winning in the next game.
In order to find the probability of several events occurring in succession, we multiply the probabilities of the individual events.
Therefore if Lester plays one number seven times, the probability that all seven bets lose are
or
Step 1:
Multiply the numbers in parentheses:
(-3 * 2) - (7 * (- 3)) - 10
-6 - (- 21) -10
Step 2:
Equal signs are added:
-6 + 21-10
Step 3:
Make the algebraic sum:
-6 + 21-10 = 5
Answer:
the final result is 5.
