Answer: No, the events are not mutually exclusive
Work Shown:
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.51 + 0.79 - 0.66
P(A and B) = 0.64
Since the result is not zero, this means the events are not mutually exclusive.
Mutually exclusive events are ones that cannot happen at the same time. Example: getting a "2" and a "3" on the same roll of a number cube.

5. The ratio of the number of John's stamps to the number of Peter's stamps is 5:8. Peter has 18 more stamps than John. If Peter gives 22 stamps to John, what will be the new ratio of the number of John's stamps to Peter's?
Answer:
2:1
Step-by-step explanation:
J:P = 5:8
30:48
48-30= 18
48-22= 26
30+22= 52
new ratio
52:26
2:1

what is the standard form for ( 4 × 10 ) + ( 3 × 1 100 ) + ( 5 × 1 1000 )
The standard form of the expression (4 × 10) + (3 × 1/100) + (5 × 1/1000) is 40.035
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have expression:
= (4 × 10) + (3 × 1/100) + (5 × 1/1000)
= 40 + 0.03 + 0.005
= 40.035
Thus, the standard form of the expression (4 × 10) + (3 × 1/100) + (5 × 1/1000) is 40.035

Carmen is going to build some large wooden storage boxes. The boxes are shaped like rectangular prisms, as shown below. She wants to cover all the sides of
each box with special wallpaper. If she has a total of 1498 ft? of wallpaper, how many boxes can she cover?
Answer:
7 boxes
Step-by-step explanation:
The area of a rectangular prism is given by the formula ...
A = 2(LW +H(L+W))
The amount of wallpaper Carmen needs for one box is found by computing the area of the box.
__
One boxA = 2(5·6 +7(5+6)) = 2(30 +7·11) = 2(107) = 214 . . . square feet
All boxesCarmen will be using a total of 214x square feet of wallpaper to cover x boxes. She has 1498 ft² available, so can cover ...
1498 ft²/(214 ft²/box) = 7 boxes
Carmen has enough wallpaper to cover 7 storage boxes.
The measures of the angles between the resultant and two applied forces are 26° and
20°, and the magnitude of the resultant is 80 pounds. Find the magnitude of the
larger force, to the nearest 10th of a pound.
Answer:
48.8 lbs
Step-by-step explanation:
The forces can be modeled by a triangle with acute angles 20° and 26°, and obtuse angle 134° opposite a side of length 80. The larger component force will be opposite the angle 26°, and can be found using the Law of Sines:
a/sin(A) = c/sin(C)
x/sin(26°) = 80/sin(134°)
x = 80sin(26°)/sin(134°) ≈ 48.753 . . . . pounds
The larger component force is about 48.8 pounds.

if the zeros of a quadratic formula function F are -2 and 4 what is the equation of the axis of symmetry F?
Option 2 is correct.
The axis of symmetry is, x= 3
Step-by-step explanation:
Given: The zeros of the quadratic function f are 1 and 5.
If the zeroes are at x =1 and at x =5, then,
the factor equations were x- 1=0 and x-5 = 0.
Then. the factors were x -1 and x-5 .
Any factorable quadratic is going to have just the two factors, so these are must be them.
Then, the original quadratic was :
or
[by distributive property ]
Combine like terms;

A quadratic equation is of the form: ; where a, b, c are the coefficient ]
On comparing equation [1] with general equation we have;
the value of a = 1 , b = -6 and c =5
Axis of symmetry states that a parabola is a vertical line that divides the parabola into two congruent halves.

Then;
Axis of symmetry (x) =

First integral:
Parameterize -C (the reverse of C) by [tex]z = e^{it}[/tex] where [tex]0\le t \le\frac\pi2[/tex]. Then the contour integral is
[tex]\displaystyle \int_{-C} (z^2 - z + 2) \, dz = \int_0^{\frac\pi2} \left(e^{2it} - e^{it} + 2\right) i e^{it} \, dt[/tex]
[tex]\displaystyle = i \int_0^{\frac\pi2} \left(e^{3it} - e^{2it} + 2e^{it}\left) \, dt[/tex]
[tex]\displaystyle = i \left(\frac1{3i} e^{3it} - \frac1{2i} e^{2it} + \frac2i e^{it}\right) \bigg|_0^{\frac\pi2}[/tex]
[tex]\displaystyle = \left(\frac13 e^{3it} - \frac12 e^{2it} + 2 e^{it}\right) \bigg|_0^{\frac\pi2}[/tex]
[tex]\displaystyle = -\frac43 + \frac53i[/tex]
Then
[tex]\displaystyle \int_C (z^2-z+2) \, dz = -\int_{-C} (z^2+z-2) \, dz = \boxed{\frac43 - \frac53i}[/tex]
Second integral:
The integrand has a pole of order 2 at z = 3i which is contained in C. By the residue theorem,
[tex]\displaystyle \int_C \frac{z^2+z}{(z-3i)^2} \, dz = 2\pi i\, \mathrm{Res}\left(\frac{z^2+z}{(z-3i)^2}, z=3i\right)[/tex]
Compute the residue:
[tex]\displaystyle \mathrm{Res}\left(\frac{z^2+z}{(z-3i)^2},z=3i\right) = \lim_{z\to3i} \frac{d}{dz}\left[z^2+z\right] = \lim_{z\to3i} (2z+1) = 1 + 6i[/tex]
Then the value of the integral is
[tex]\displaystyle \int_C \frac{z^2+z}{(z-3i)^2} \, dz = 2\pi i (1 + 6i) = \boxed{-12\pi + 2\pi i}[/tex]

Answer:
22.5 km
Step-by-step explanation:
Since 1 cm on the map is 250000 cm in real life :
We can convert 250000 cm to km :
First we convert to m :
250000 ÷ 100 = 2500 m
Now we convert m into km :
2500 ÷ 1000 = 2.5 km
Now we multiply 2.5 km by 9 cm to get :
2.5 × 9 = 22.5 km
Therefore the 2 villages are 22.5 km apart.
Hope this helped and brainliest please.Answer:
2.25 million km
Step-by-step explanation:
Step 1. Write ratio with "x"
Step 2. Create a proportion
Step 3. Cross multiply
Step 4. Solve for "x"
1 : 250,000
9 cm : x km
1/250,000 = 9/x
x = (9)(250,000)
x = 2.25 million km

A function f is odd and f(x)=x2 for all x>0. Sketch the graph of this function and then write the rule of this function as a single formula.
f(x)=
For the function to be an odd function, then f(-x) = -f(x) and the function f(x) is not an odd function
How to determine the function?The function f(x) is given as:
f(x) = x^2
For the function to be an odd function, then the following must be true:
f(-x) = -f(x)
So, we have:
f(-x) = (-x)^2 = x^2
-f(x) = -x^2
From the above computation, we can see that the functions f(-x) and -f(x) are not equal
Hence, the function f(x) is not an odd function
