Answer:
A) Yes, because P (F∩S) = 0
Step-by-step explanation:
Hello!
50 customers of a store were asked to choose between two discounts:
Discount 1: 20% off all purchases for the day.
Discount 2: 10% off all purchases for the week.
28 choose discount 1
22 choose discount 2
F: the selected person choose discount 1.
S: the selected person choose discount 2.
Two events are mutually exclusive when the occurrence of one of them prevents the other from occurring in one repetition of the trial and the intersection between these two events is void with zero probability of happening.
In this case, since the customers were asked to choose one out of the two events, if the customer chooses the first one, then he couldn't have chosen the second one and vice-versa. Then the intersection between these two events has zero probability, symbolically:
P(F∩S)=0
I hope it helps!
To write this as a numerical expression, you will think of the different parts of the math story that are occurring and put them together in one math statement. You have 12 books being ordered that are $9 each AND are paying a $15 shipping charge. This can be written as 12 x $9 + $15. There are 2 terms here - these are the 2 parts! Multiply 12 times 9 first to get $108, then you can add the $15 shipping fee. You can only add units that are the same, so you must multiply first. Your answer statement is a sentence that gives your final answer in a complete sentence. For example, the total cost of Lannie's order is $123.
The answer is C. the reson is because a function have to have a input that have only one output.
Answer:
no
Step-by-step explanation:
an obtuse angle is any angle more than 90⁰ but less than 180⁰. He either had an incorrect estimate or he measured incorrectly.

Answer: -4
Step-by-step explanation:
No options were provided, but i'll simplify this expression.
*the number being NEXT to the parenthesis indicates that you have to multiply.
This expression involves the distributive property. This is when you have a number followed by an equation in parenthesis, like 2(3+1). To solve it, you multiply the number outside of the parenthesis by <u>each number</u> inside them.
-2(5-3)
-2(5) - -2(3)
-10 + 6
-4
So -2(5-3) simplifies to -4. I hope this could help!!
