Answer:
The two events are independent
Step-by-step explanation:
Since the king was placed back in the deck and the deck was re-shuffled,
the drawing of a king does not effect the probability of subsequently drawing a queen.
The probability of picking the queen is independent of the probability of picking the king.
pick a card from a shuffled pack and draw a king. You put it back in the pack, shuffle, and then pick another card. This time you draw a queen. How are the two events of picking a king and picking a queen related to be justified
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
There is a 52-card deck.
Pick a card from a shuffled pack and draw a king. You put it back in the pack, shuffle,
Probability can be given as for the draw of the king,
p = 1/52
Put it back in the pack, shuffle, and then pick another card. This time you draw a queen.
Probability can be given as for the draw of the queen,
p = 1/52
Since both probabilities is the same it implies the probability of one event is independent of the other.
Thus, the probability of picking the queen is independent of the probability of picking the king.

A person looking out a window, 40 feet above street level can sight the top and
bottom of the building. The angle of elevation to the top of the building is 61 degrees and the angle
f depression to the bottom of the building is 37 degrees. How tall is the building that the person is looking at
Answer:
135.94 feet
Step-by-step explanation:
Split the problem into two parts :
Distance between viewer and buildingHeight of the top part of the buildingDistance between viewer and building
The lower part of the building is 40 feet, as it is mentioned the viewer is 40 feet above street levelLet the distance be called 'd'Therefore, tan37° = 40/dtan37° = 3/4 = 0.75⇒ 40/d = 0.75⇒ d = 40/(3/4) = 40 x 4/3 = 160/3 = 53.3 feetHeight of the top part of the building
Let the height of the top part be 'h'Therefore, tan61° = h/d = h/53.3tan61° = 1.8⇒ h/53.3 = 1.8⇒ h = 53.3 x 1.8 = 95.94 feetTotal height of building
Lower part + Top part40 + 95.94135.94 feetDan and George share 18
is in the ratio 1:2
How many bananas does Dan get?
Dan gets 6 bananas and George gets 12 bananas

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

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.

Answer:
60 small and 140 large = 60 + 280 = 340 this is correct!
Step-by-step explanation:
I guess we just use the process of eleimation.
50 small and 150 Large = 50+300 = 350 so that's not right.
130 small and 70 large = 130 + 140 = 270 so, that's not right.
120 small and 80 large = 120 + 160 = 280 so, that's not right.
60 small and 140 large = 60 + 280 = 340 this is correct!

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.

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.

7-ounce package costs $2.38. A
15-ounce package costs $5.25. A
26-ounce package costs $8.58. Which
package is the best buy?
Answer:
Step-by-step explanation:
Remark
If you find out the cost of 1 oz of each of them, that will determine the best buy. The smallest number is the best buy.
Givens
7 oz cost $2.38
15 oz cost $5.25
26 oz cost $8.58
Solution
7 oz7 oz cost $2.38
1 oz cost x This is a proportion. 3 quatities are known. Find x Cross multiply.
7/1 = 2.38/x
7x = 2.38
x = $0.34 dollars
15 oz15 oz cost 5.25
1 oz costs x
15.1/1 = 5,25 x Cross Multiply
15x = 5.25 * 1 Divide by 15
x = 5.25 / 15
x = $0.35
26 oz26 oz cost 8.58
1 oz cost x
26/1 = 8.38/x Cross Multiply
26x = 8.38 Divide by 26
x = 8.38/20
x = 0.32 dollars
Answer
7 oz cost 0.34
15 oz cost 0.35
26 oz cost 0.32
The best buy is 0.32 / oz for 26 oz
