Step-by-step explanation:
Since PT = 2PM and AR = 2AD,
The midsegment MD must be the average of PA and TR:
Therefore we have
2(20x + 4) = 10 + (34x + 16)
=> 40x + 8 = 34x + 26
=> 6x = 18
=> x = 3
Hence length of MD
= 40(3) + 8 = 128.
an online spinner has two colored regions--blue and yellow. according to the website, the probability that the spinner lands in the blue region on any spin is 0.80. Assume for now that this claim is correct. Suppose we spin the spinner 12 times and let x = the number of times it lands in the blue region.
Explain why X is a binomial random variable.
Answer:
Skewed Left :)
Step-by-step explanation:
Correct on Edge 2021
The probability of success (p = 0.8) in each trial remains constant.
The trials are independent. This implies that the outcome from one trial has no effect on the outcome to be obtained from any other trial.
Each trial results in only two possible outcomes, labeled as the success ( Blue ) and failure ( Not blue ).
The experiment is performed a fixed number of times (n=12).
The X is a binomial random variable is 0.1329.
Given that,
An online spinner has two colored regions--blue and yellow.
According to the website, the probability that the spinner lands in the blue region on any spin is 0.80.
Assume for now that this claim is correct. Suppose we spin the spinner 12 times.
We have to determine,
X is a binomial random variable.
According to the question,
The experiment is performed a fixed number of times (n=12).Each trial results in only two possible outcomes, labeled as the success ( Blue ) and failure ( Not blue ).
The trials are independent. This implies that the outcome from one trial has no effect on the outcome to be obtained from any other trial.
The probability of success (p = 0.8) in each trial remains constant.
Therefore,
Number of trials: n = 12
Probability of success: p = 0.8
Let, x be the number of successes ( Blue ) in 12 trials.
The probability function of X:
[tex]P(X=x) = \ ^nC_x \times P^x \times (1-p)^{n-x}[/tex]
To find P(X = 8). Interpret this value in context.
At x = 8
[tex]P(X=8) = \ ^{12}C_2 \times (0.8)^{8} \times (1-0.08)^{12-8}\\\\P(X=8) = \dfrac{12!}{10!\ 2!} \times (0.8)^8\times (0.92)^4\\\\P(X=8) = 495 \times (0.167) \times (0.0016)\\\\P(X=8) = 0.1329[/tex]
Hence, The X is a binomial random variable is 0.1329.

What is the range of possible sizes for side x? the other two sides are 8.0 and 8.5
Answer: 0.5 < x < 16.5.
Step-by-step explanation:
Given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)Difference between the sides < third side. (ii)If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.
Answer:
0.5, 16.5

A carpenter has at most $250 to spend on lumber. The inequality 8x+12y≤250 represents the numbers x of 2-by-8 boards and the numbers y of 4-by-4 boards the carpenter can buy. Can the carpenter buy twelve 2-by-8 boards and fourteen 4-by-4 boards?
Answer:
No, (12, 14) this is not a solution of the inequality
Step-by-step explanation:
(x, y)
x = 12 2-by-8 boards
y = 14 4-by-4 boards
(12, 14)
8x + 12y <= $250
This means that a 2-by-8 board cost $8 each, while a 4-by-4 board cost $12 each.
8(12) + 12(14) <= 250
96 + 168 <= 250
264 <= 250
264 is not less than or equal to 250

Alicia is writing the program for a video game.
For one part of the game, she uses the rule
(x,y)→(x−7,y+2)
to move points on the screen.
What output does the rule give when the input is
(−4,−6)
? Show your work.
What output does the rule give when the input is
(2,−9)
? Show your work.
Answer:
(-11,-4) and (-5,-7)
Step-by-step explanation:
the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.
Apply the rule to the 1st question by plugging in the coordinates:
(x,y)→(x−7,y+2)
(−4,−6)→((-4)−7,(-6)+2)
(−4,−6)→(-11,-4)
Let's use the same process for the 2nd question:
(x,y)→(x−7,y+2)
(2,−9)→((2)−7,(-9)+2)
(2,−9)→(-5,-7)

Answer:
C x=40, y=30
Step-by-step explanation:
Remember the opposite side of parallelogram is the same
so angle C and angle A is the same.
3x=120
divide both sides by 3 and you get 40
All parallelogram equal to 180 degrees so to find y
180=2y+120
-2y=120-180
-2y=-60 negative divide negative is positive.

What is the equation of the line in slope-intercept form?
Answer:
[tex]\bold{y=-\frac12x}[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + b
The line intersect Y-axis at y=0 so b = 0
The line passses through points (0, 0) and (2, -1), so the slope:
[tex]m=\dfrac{-1-0}{2-0}=-\dfrac12[/tex]
Therefore the equation:
[tex]y=-\frac12x+0\\\\y=-\frac12x[/tex]

Answer:
y = 48, x = 11
Step-by-step explanation:
6x = 3x + 33
3x = 33
x = 11
6x + 3x + 33 + y = 180
66 + 33 + 33 + y = 180
66 + 66 + y = 180
132 + y = 180
y = 180 - 132
y = 48

A 14 1/2 foot by 30 foot concrete wall is to be built using concrete blocks. Find the area of the wall
Answer:
The area of the wall is 435 square foot.
Step-by-step explanation:
a) Data and Calculations:
One side of the wall (height) = 14 1/2 foot = 14.5 foot
The second side of the wall (length) = 30 foot
The area of the wall = height * length
= 14.5 * 30
= 435 square foot
b) The area of a wall is usually obtained by Height x Length. It uses the same standard formula of (Length) x (Width) for calculating the area of any surface, only that this time, the width changes to height because of the nature of the wall.

Select the statement that does not correctly use probability to describe an
event.
O A. The probability of a storm tomorrow is 60%.
B. The probability of finding a matching pair of socks is 1/3
C. The probability of taking a good class picture is 1.3.
D. The probability that the dog will catch the ball is 0.99.
Answer:
Option C is correct option.
Step-by-step explanation:
We need to select the statement that does not correctly use probability to describe an event.
Probability
Whenever we need to find probability of something it lies between 0 and 1.
So, if any item has probability greater than 1 then it is incorrectly described.
Now, looking at the options:
A. The probability of a storm tomorrow is 60%.
Here probability is 0.6 (60/100 = 0.6) so it is used correctly
B. The probability of finding a matching pair of socks is 1/3
Here probability is 0.33 (1/3 = 0.33) so it is used correctly
C. The probability of taking a good class picture is 1.3.
Here probability is 1.3 but probability can be between 0 and 1. So here it is not used correctly.
D. The probability that the dog will catch the ball is 0.99.
Here probability is 0.99 so it is used correctly
Therefore Option C is correct option.
Answer:
C. The probability of taking a good class picture is 1.3

The longest length side of an acute isosceles triangles is 12 centimeters. Rounded to the nearest tenth, what is the smallest possible length of one of the two congruent sides
Answer:
8.5
Step-by-step explanation:
Given that;
The longest side of an acute isosceles triangle = 12 centimeters
Since the two remaining sides are congruent, then they both have the same length ;
Let the length of the two remaining sides = 2x,
The length of each side :
Length of longest side / sqrt(2)
x = 12 /sqrt(2)
x = 12 / 1.4142135
x =8.4852813
x = 8.5

Step-by-step explanation:
First off, we're not given the hypotenuse's length, so let's use the Pythagorean Theorem to find it:
[tex]1^2+3^2=c^2\\1+9=c^2\\10=c^2\\c=\sqrt{10}[/tex]
With that, we can refer to SOH-CAH-TOA to help us find sine, cosine, and tangent:
SOH (Sine = Opposite/Hypotenuse)
[tex]\sin{\theta}=1/\sqrt{10}=\sqrt{10}/10[/tex]
CAH (Cosine = Adjacent/Hypotenuse)
[tex]\cos{\theta}=3/\sqrt{10}=3\sqrt{10}/10[/tex]
TOA (Tangent = Opposite/Adjacent)
[tex]\tan{\theta}=1/3[/tex]
From this, we can see that A matches up with sine, and we can eliminate B and C.
Cosecant, secant, and cotangent are all reciprocals of the three basic trig ratios:
[tex]\csc{\theta}=1/\sin{\theta}=\sqrt{10}\\\sec{\theta}=1/\cos{\theta}=\sqrt{10}/3\\\cot{\theta}=1/\tan{\theta}=3[/tex]
D matches with cosecant, and F matches with cotangent, so the correct trig rations for θ are A, D, and F.
