Hi i need to identify the congruence postulation i think i need help.
EASY 15 POINTS!
what is the area?
shape below
358 in^2
94 in^2
168 in^2
242 in^2
Answer:
Area of rectangle= 24 × 7 = 168
Area of trapezium = ((a+b)/2)h = 74
Total area = 168 + 74 = 242
Answer:
242in^2
Step-by-step explanation:
Area of parallelogram is
1/2(a+b)×h
a=13in
b=24in
h=4in
= 1/2(13+24)×4
=1/2(37)×4
so the area of the parallelogram is
=74in^2
Area of rectangle is
L×B
L=24in
B=7in
=24×7
=168in^2
so the area will be the sum of the area of parallelogram and rectangle
=74in^2+ 168in^2
=242in^2

What is the arc measure, in degrees, of ADC on circle P below?
70°
104°
Answer:
The answer is "[tex]\overarc{ADC} = m\angle CPD + m\angle DPA = 186[/tex]"
Step-by-step explanation:
Please find the image of the question:
In the circle p:
[tex]\to m\angle APB + m\angle BPC + m\angle CPD + m\angle DPA = 360^{\circ} \\\\\to 70 + 104 + m\angle CPD + m\angle DPA = 360\\\\\to m\angle CPD + m\angle DPA = 360 - 70 - 104 = 186[/tex]
Let P is in the center
[tex]\to[/tex] arc AD= [tex]m\angle APD[/tex]
[tex]\to[/tex] arc DC = [tex]m\angle CPD[/tex]
[tex]\to[/tex] arc BC = [tex]m\angle BPC[/tex]
arc AB =
When D is on arc AC:
[tex]\to[/tex]arc ADC = arc AD + arc DC
[tex]\to[/tex]arc ADC = [tex]m \angle CPD + m\angle DPA = 186[/tex]
A game is played with the following rules. Three ordinary coins are flipped and count as a single "turn" in the game.
Each coin could land on heads or tails. After their turn a player is given a certain number of points depending on the
outcome.
•If the result is 3 heads, the player receives +4 points.
• If the result is 2 heads, the player receives +2 points.
• If the result is anything else, the player receives -1 point.
What is the expected value of the number of points a player will receive after a turn?
=======================================================
Explanation:
H = heads
T = tails
Something like HHT means we get two heads in a row at first, followed by one tail. The order matters. Since there are 2 sides per coin, and 3 coins, this leads to 2^3 = 8 different possible ways to flip three coins.
Those 8 outcomes are:
HHHHHTHTHHTTTHHTHTTTHTTTAgain the order matters.
------------
Now let's define the following events
A = event of getting three headsB = event of getting exactly two headsC = event of getting 1 head, or getting 0 headsThere's only one way to get three heads, and that's HHH. So P(A) = 1/8.
There are three ways to get exactly two heads. Those three ways are: HHT, HTH, THH. This means P(B) = 3/8.
From those two probabilities, we then know that P(C) = 4/8 = 1/2 since there are 1+3 = 4 ways to get two or more heads, leaving 8-4 = 4 ways to get the other situations.
Now let's define function notation V(A) to mean "the net value of event A occurring". It's the number of points you receive if event A happens. We are given the following info:
V(A) = 4V(B) = 2V(C) = -1From here, multiply the probability values with their corresponding net values
P(A)*V(A) = (1/8)*(4) = 0.5P(B)*V(B) = (3/8)*(2) = 0.75P(C)*V(C) = (1/2)*(-1) = -0.5Finally, add up those results to get the expected value: 0.5+0.75+(-0.5) = 0.75
Each time a turn happens, we expect on average to get 0.75 points
Imagine a scenario where you play the game 10,000 times. If you record the result of each turn and then compute the arithmetic mean, you should get somewhere close to 0.75; it likely wont be 0.75 exactly due to the nature of theoretical probability and empirical probability not being perfectly aligned. However, due to the law of large numbers, the two should be very close when you do a large number of trials.
Because we're dealing with averages, it is possible to get a decimal value as the answer even though the point values of events A,B,C are integers.
A submarine started 30 feet below the surface of the water. It is now 10 feet below the surface. What integer represents the change in depth?
Answer:
-20 feet
Step-by-step explanation:
change in depth = number of feet below the surface + number of depth on the surface
Because the submarine is below surface, a value of -30 would be given
-30 + 10 = -20 feet

The length of a rectangle is 15cm more than its width and perimeter is 150cm. Find the length and width of the rectangle.
Pls help as I'm preparing for my exams
Answer:
Hope this helps you..
Brainliest plsssss
All the Best for your exams
Step-by-step explanation:
let the breadth=x
the length =x+15
given perimeter= 150
Perimeter of rectangle = 2x(l+b)
150 = 2( x+ x+15)
75 = 2x +15
60 = 2x
30=x
therefore breadth = 30 cm
length = 30 +15 = 45 cm
Verification:
150 = 2( 45+30)
150 = 2(75)
150 = 150
LHS=RHS
Hence, proved..
Answer:
Step-by-step explanation:
Let the breadth(b) be x . Then by the question
Length (L) = ( x + 15 )cm
Perimeter = 150 cm
or 2( L + b) = 150
2 ( x + 15 + x ) = 150
2x + 15 = 75
2x = 75 - 15
2x = 60
x = 30 cm
Therefore breadth or width is 30 cm
Similarly
Length = 30 + 15 = 45
hope it helps :)
The box plot show the lengths of the songs on two digital music players in minutes .Which statement is best supported by the information in the box plots ?
Solution :
In the figure, the box plot represents the lengths of the songs of the two digital music players that is in minutes.
From the figure, we can see that for the music player Y, the interquartile range of the data is small.
And the interquartile range of data is more for the music player X.
So, we can conclude that the interquartile range of data is greater for Music player X than the interquartile range data of music player Y.
