The correct option a. No, because the probabilities P(E) and P(F) add up to more than 1.
What is termed as the disjoint sets?Disjoint sets are the ones in which their intersection results in such a null set. In set theory, we sometimes notice that two sets have no common elements, or that the intersection of a sets is an empty set or null set. This is referred to as a disjoint set. For instance, if we have X = a, b, c and Y = d, e, f, we can say that given 2 sets are disjoint because they have no common elements.For the given condition;
P(E) = P(F) = 0.7
the sum of both will be.
P(E) + P(F) = 1.4
But, we know that probability can never be more than 1.
Thus, there must be some elements which are common in both sets, which makes the set disjoint.
Thus, events E and F are not disjoint events.

the sum of the three numbers in 2003,two of the numbers are 814 and 519 what is the third number
Answers
Answer:
670
Step-by-step explanation:
2003-814=1189
1189-519=670
Answer: The third number is 670.
Step-by-step explanation:
The sum means three numbers being added up is equal to 2003 so give two of those numbers you have to add them up and subtract it from 2003 to find the third number.
814 + 519 + x = 2003 where x is the third number
1333 + x = 2003
-1333 -1333
x = 670 So the third number is 670
Check:
814 + 670 + 519 = 2003
2003 = 2003 so yes again 670 is the third number.
what are the coordinates of point b on ac such that ab=2/5ac
Answers
Answer:
\((-\frac{36}{7},\frac{40}{7})\)
Step-by-step explanation:
Coordinates of points A and C are (-8, 6) and (2, 5).
If a point B intersects the segment AB in the ratio of 2 : 5
Then coordinates of the point B will be,
x = \(\frac{mx_2+nx_1}{m+n}\)
and y = \(\frac{my_2+ny_1}{m+n}\)
where \((x_1, y_1)\) and \((x_2,y_2)\) are the coordinates of the extreme end of the segment and a point divides the segment in the ratio of m : n.
For the coordinates of point B,
x = \(\frac{2\times 2+(-8)\times 5}{2+5}\)
= \(-\frac{36}{7}\)
y = \(\frac{2\times 5+5\times 6}{2+5}\)
= \(\frac{40}{7}\)
Therefore, coordinates of pint B will be,
\((-\frac{36}{7},\frac{40}{7})\)

Helen has a 4 kilometer-head start on París how long will it take París to catch Helen if helen travels at 6 kilometers per hour and París traveled at 8 km per hour
Answers
Assume "h" = number of hours traveled
Helen's speed = 6km per hour and is 4km advanced than Paris
Paris' speed = 8km per hour
Therefore, we can form the following equations:
a. Helen's distance traveled = 4km + 6km (h) = 4 + 6h
b. Paris' distance traveled = 8km (h) = 8h
For us to determine how long will Paris be able to catch Helen, we'll have to assume they have traveled the same distance. In this case:
Helen's distance traveled = Paris' distance traveled
\(\begin{gathered} 4+6h=8h \\ \text{Subtrach 6h on both sides of the equation.} \\ 4+6h-6h=8h-6h \\ 4=2h \\ \text{Divide two on both sides.} \\ \frac{4}{2}=\frac{2h}{2} \\ 2=h \end{gathered}\)Therefore, it will take 2 hours for Paris to catch up with Helen which is at 16km.

Answers
Answer:
-2
Step-by-step explanation:
8x + 4y = 64 Put into slope intercept form
4y = -8x + 64
Divide by 4
y = -2x + 16
Slope is -2
2y = 4x - 12
Find the x and the y intercept of the line.
Answers
0 = 4x - 12
Adding 12 to both sides:
12 = 4x
Dividing both sides by 4:
3 = x
For Y:
2y = 4(0) - 12
2y = -12
Dividing both sides by 2:
y = -6
Therefore, the y-intercept of the line is y = -6.

The following graph describes function 1, and the equation below it describes function 2:
Function 1
graph of function f of x equals negative x squared plus 8 multiplied by x minus 15
Function 2
f(x) = −x2 + 2x − 3
Function ____ has the larger maximum.
(Put 1 or 2 in the blank space)
Answer:
Answers
Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.

A shopper buys cat food in bags of 33 lbs. Her cat eats \frac{3}{4}
4
3
lb each week. How many weeks does one bag last?
Answers
Total of 44 weeks does one bag last.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator
Total amount of cat food = 33 lbs in one bag
Amount of food cat eats each week = 3/4 lb = 0.75 lb
Number of weeks one bag of cat food last = 33 / 0.75
= 44
Hence one bag of cat food will last for 44 weeks.

I need help please I can only find 2 of these solutions
Answers
Step 1: Isolate the Sin Operator
\(8 sin(\frac{\pi }{6} x)=2\\sin(\frac{\pi }{6} x)=0.25\\\\\)
Step 2: Use Inverse Sin(arcsin) to isolate the term with the x variable
Note that since trig functions have 2 general solutions, this will give us one of our general solutions.
\(x=\frac{6 arcsin(0.25)}{\pi } =0.48\)
x₁= 0.48
Solving for x₂
Use the period identity for Sin Functions
\(sin(x)=sin(\pi -x)\)
X in this case is arcsin(0.25)
\(\frac{\pi }{6} x=\pi -arcsin(0.25) = 5.52\)
So our two general solutions are 0.48 and 5.52
Step 3: Period
Trig Functions have periodic behavior and this function period is
\(\frac{2\pi }{1} (\frac{6}{\pi } )= 12\)
So our general solutions are
0.48±12k, where k is an integer
5.52±12k, where k is an integer
Let k=1, and we get our next set of solutions:
12.48 and 17.52
So our answer is 0.48,5.52,12.48,17.52

According to Runzheimer International, a typical business traveler spends an average of $281 per day in Chicago. This cost includes hotel, meals, car rental, and incidentals. A survey of 70 randomly selected business travelers who have been to Chicago on business recently is taken. For the population mean of $281 per day, what is the probability of getting a sample average of more than $ 275 per day if the population standard deviation is $47?
Answers
The probability of getting a sample average will be "0.9454".
Given values are:
Population mean,
μ = 281Sample average,
\(\bar{x}\) = 275Standard deviation,
σ = 47Randomly selected business travelers,
n = 70Now,
→ \(P(\bar{x} > 275)=P(Z > \frac{\bar {x} - \mu}{\frac{\sigma}{\sqrt{n} } })\)
→ \(= P(Z > \frac{275-281}{\frac{40}{\sqrt{70} } } )\)
→ \(= P(Z > -1.6021)\)
→ \(= 0.9454\)
