The angle W equal to 24.3
In a triangle sum of three angles is equal to 180
W = (3x-24) degree
C = (4x-11) degree
T = 2x degree
3x-24+4x-11+2x=180
9x-35=180
9x=180-35
9x= 145
x=16.1
substitute the value of x in W equation
W = 3(16.1)-24 = 24.3
The value of angle W is 24.3

Rosa's friend jake claims that he can read minds. To test jake's abilities, rosa chooses 333 different numbers from 111 to 101010. Rosa then asks jake to identify which 333 of the 101010 numbers she chose in the correct order. Assume that jake has no special abilities and is randomly guessing the numbers. What is the probability that jake correctly identifies all 333 numbers in the correct order?.
By using the concept of Probability, the result obtained is -
Probability of guessing the correct order = [tex]\frac{1}{720}[/tex]
What is Probability?
Probability gives us the information about how likely an event is going to occur
Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probality of any event is greater than or equal to zero and less than or equal to 1.
Probability of sure event is 1 and probability of unsure event is 0.
There are 10 numbers from 1 to 10
Number of favourable outcomes = 10 [tex]\times[/tex] 9 [tex]\times[/tex] 8
= 720

Select the correct answer from each dropdown menu. Consider this expression. The simplest form of the expression has in the numerator and in the denominator?
The simplest form of the expression has 4 in the numerator and (x-2) in the denominator.
What are numerator and denominator?The numerator indicates the total number of selected equal parts. Whereas, the denominator indicates the total number of equal parts.
We have the expression
3/(x-2) + (x-2) / (x²-4x+4)
Simplifying x²- 4x +4 gives (x-2)².
Therefore, we can write the expression as
3/(x-2) + (x-2)/(x-2)² = 3/(x-2) + 1/(x-2)
= 4/(x-2).
Therefore, the simplest form of the expression has 4 in the numerator and (x-2) in the denominator.

I don't know what I'm suppose to do.
The equation of a line is y = mx +b
m = slope - which is equal to 1
x = x coordinate
b = y intercept (where the line hits the y axis)
y = y coordinate.
The point (2, 0) shows that when x = 2, y = 0. So we can plug that into the equation:
0 = 1(2) + b
0 = 2 + b
0 - 2 = 2 -2 +b
-2 = b
So the equation of the line is y = x - 2

Cora is playing a game that involves flipping three coins at once. Let the random variable hhh be the number of coins that land showing "heads". Here is the probability distribution for hhh:.
Cora is flipping three coins at once. The probability that the number of landed coins showing "heads" is less than 3 is 0.875
Probability is a measure how likely an event occurs. Probability of an event A is calculated as:
P(A) = number of ways A can occur / total possible outcomes
Let A and B be independent events, then the followings hold:
P (A and B) = P (A∩B) = P(A) + P(B)
P (A or B) = P (A∪B) = P(A) · P(B)
P (not A) = P(Ā) = 1 - P(A)
In the given problem, H is an event where the number of landed coins showing heads.
The probability distribution for H is:
P(H = 0) = 0.125
P(H = 1) = 0.375
P(H = 2) = 0.375
P(H = 3) = 0.125
The probability of three coins show heads less than 3 is:
P(H < 3) = 1 - P(H=3)
= 1 - 0.125 = 0.875
It can also be obtained using:
P(H<3) = P(H=0) + P(H=1) + P(H=2)
= 0.125 + 0.375 + 0.375
= 0.875
Hence, the probability of three coins show heads less than 3 is 0.875.
Complete question:

Jerry's seed palace claims that 80% of its lima bean seeds will germinate. Suppose the company's claim is true. Callie buys a packet with 20 lima bean seeds from jerry's seed palace and plants them in her garden. What is the probability that exactly 14 seeds will germinate?.
The probability that exactly 14 seeds will germinate is 0.109
According to the company, 80% of lima bean seeds germinate.
Callie purchases 20 lima beans.
To determine: the likelihood that exactly 14 seeds will germinate.
We use the binomial distribution to obtain the required probability when we need to track the success and failure of multiple objects (multiple Bernoulli trials)
Let X be the random variable that tracks the number of seeds that germinate out of a total of 20 seeds. The success rate is 80%, or 0.8.
Thus X ~ B(20,0.8)
The probability of X = x is given by:
P(X=x) = 20[tex]C_{x}[/tex][tex](0.8)^{x}[/tex][tex](1-0.8)^{20-x}[/tex]
Thus
P(X=14) = 20[tex]C_{14}[/tex][tex](0.8)^{14}[/tex][tex](1-0.8)^{20-14}[/tex]
P(X=14) = 38760 × 0.04398 × 0.000064 = 0.109
The probability that exactly 14 seeds will germinate is 0.109

In the triangle ABC, the side lengths, in order from the greatest to the least, are : AC > AB > BC.
We are given a triangle. The vertices of the triangle are A, B, and C. The measures of the angles ∠A, ∠B, and ∠C are 36°, 84°, and 60°, respectively. We need to arrange the side lengths in order from the greatest to the least.
The side lengths are proportional to their opposing angles in a triangle. It means that the side opposite the largest angle is the largest side, and vice versa. The angles arranged in descending order are : 84° > 60° > 36°. The angles arranged in descending order according to the vertices are : B > C > A. The order of the lengths of the opposite sides must be the same.
Hence, the side lengths, in order from the greatest to the least, are : AC > AB > BC.

It is impossible to travel for the same 60-mile distance home to average 60mph over the entire trip.
car travels a distance of 60 miles long and averages 30 miles per hour. As a result,
time = distance/speed = 60/30 = 2
the car traveled for 2 hours.
The car would have to travel for exactly 2 hours (120/60) to average 60 mph over 120 miles.
Because the car has already traveled for two hours, it is impossible for it to average 60 mph for the duration of the journey.
