<span>Graphing calculators are more accurate and are faster when finding the solution(s). <span>When solving a system of equations with a graphing calculator, you can have the calculator graph equations of any degree and shape. The graphing calculator also has functions to find where the graphs intersect between two points and are accurate sometimes to ten decimal places. When compared to graphing by hand you can get inaccurate results and results that are not as precise.</span></span>
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!
Answer:
Step-by-step explanation:
<em><u>The correct question is </u></em>
If ABCD is a square and AB = 10, what is the measure of AC? (rounded to the nearest hundredth)
see the attached figure to better understand the problem
we know that
All four sides of the square are congruent and all four interior angles are equal to 90°.
so
AB=BC=CD=AD
In the right triangle ACD
Applying the Pythagorean Theorem
we have that
substitute the given value
With 6 people preparing bags, they would be able to prepare 6 bags every 2 minutes.
900/6 * 2 = the total minutes
Divide that answer by 60 to get the numbe of hours.
The answer is 5 hours.
Hope that helps.- UF aka Nadia
