In order to solve the challenges we encounter every day, Problem solving strategies are needed. To tackle a specific problem, we must first comprehend it, then create a plan for resolving it, and finally, put the plan into action.
The techniques that a person uses to solve difficulties are referred to as problem-solving strategies. A person may experience difficulties at their place of employment or home. A problem-resolution strategy must be in place in order to address such issues.One must first understand the issue. Then, potential solutions to the issue must be identified, and the best one among the available options must be picked. The chosen approach would subsequently be put into practice.Mathematical problem-solving techniques are also necessary. One must first comprehend the issue at hand before attempting to resolve it in order to tackle a particular mathematical problem.To sum up, everyone must use problem-solving techniques to overcome the obstacles we confront.

In ΔFGH, m∠F = 54°, m∠G = °, and m∠H = °.
The complete statement is:
In ΔFGH, the measure of m∠F=54°, the measure of m∠G=90°, and m∠H = 36°
How to complete the missing blank?From the question, we have the following parameters that can be used in our computation:
Triangle = ΔFGH, The measure of m∠F = 54°The measure of m∠G = 90°The sum of angles in a triangle is 180°
So, we have the following representation
m∠F + m∠G + m∠H = 180°
Substitute the known values in the above equation, so, we have the following representation
54 + 90 + m∠H = 180°
Evaluate the sum in the above equation
This gives
144 + m∠H = 180°
Collect the like terms
m∠H = 180 - 144°
So, we have
m∠H = 36°
Hence, the value that completes the blank is 36°

Henry is standing 4 feet from the base of a tree in his yard. The tree is 14 feet tall. What is the angle of elevation the point on the ground where he is standing, to the top of the tree? Round to the nearest tenth?
Answer:
Here
Step-by-step explanation:
54.5°
Answer:
63.4
Step-by-step explanation:
First, find the height of the tree relative to Henry by subtracting his height from the tree's height: 14 feet - 4 feet = <<14-4=10>>10 feet
Next, use the formula for finding the angle of elevation: tan(angle) = opposite side / adjacent side
Since the opposite side is the tree's height relative to Henry and the adjacent side is the distance between Henry and the tree, plug in the values: tan(angle) = 10 feet / 4 feet
Solve for the angle: tan(angle) = 2.5
Since the inverse tangent function is used to find the angle given the tangent value, find the inverse tangent of 2.5: angle = tan^-1(2.5) = 63.4 degrees
Round to the nearest tenth: 63.4 degrees rounded to the nearest tenth is 63.4 degrees. Answer: {63.4}.

suppose the time it takes a nine-year old to eat a donut is uniformly distributed between 0.5 and 4 minutes, inclusive. what is the probability that a nine year old will take longer than 3 minutes to eat a donut? ( round to three decimal places)
The probability that a nine year old will take longer than 3 minutes to eat a donut is 0.667 .
Given that the time taken by 09 years old,
Consider that it takes 0.5 to 4 minutes inclusive for a 9-year-old to eat a donut.
Let X = Time
minutes, how long it takes a 9 year old to eat a donut.
Then X: U(0.5, 4).
The Probability Distribution Function:
P(X) = 1/4 - 0.5 = 0.2857
Cumulative Function would be:
F(x) = x -0.5 /0.5
The probability that a randomly selected 9-year-old child will eat a donut in at least 2 minutes is
P(X ≥ 2) = 1 -F(2)
⇒ 1 - 2 -0.5/3.5
⇒ 0.8571
b) The probability that another her 9-year-old child will eat a donut in 2 minutes or more if she has eaten a donut in 3.0 minutes or more.
P(x >2 /x> 3.0)

What is combination?
A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components

Barry has a medical plan with a $1,000 deductible, 20% coinsurance, and a $5,000 coinsurance cap. His allowable medical expenses during the past year are $18,000. How much of this amount will he have to pay out of pocket?.
Based on his deductible and coinsurance cap, the amount that Barry will pay is $4,560.
Barry will pay x amount.
Barry will be responsible for covering the entire $1,200 deductible. The remaining costs will subsequently be split between him and the insurer in a ratio of 20% to 80%, although he will not be required to pay more than $5,000.
He will consequently pay the following total out of pocket:
= Deductible + ( 20% x (Medical expenses - deductible)
Solving gives:
= 1,200 + ( 20% x (18,000 - 1,200))
= $4,560
He will pay $4,560 in total.

A random variable x has a mean of 120 and a standard deviation of 15. A random variable y has a mean of 100 and a standard deviation of 9. If x and y are independent, approximately what is the standard deviation of x - y ?.
The standard deviation of x - y is 12
X and Y are independent random variables
For random variable X, mean =120 and standard deviation =15
For random variable Y, mean =100 and standard deviation = 9
Let D be the difference of standard deviation of X and Y.
Variance can be defined as the square of standard deviation.
Hence, Variance of X = (standard deviation of X)2 = (15)2 = 225
And, variance of Y = (standard deviation of Y)2 = (9)2 = 81
SD(X - Y) = sqrt(SD(X)2 - SD(Y)2)
Hence, D = sqrt(225 - 81) = sqrt(14) = 12
Hence, the standard deviation of x - y is 12

An airplane is preparing to land at an airport. It is 35,400 feet above the ground and is descending at the rate of 3,300 feet per minute. At the same airport,another airplane is taking off and will ascend at the rate of 2,600 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be?
They will be at the same altitude in minutes, when their altitude will be feet.
The time at which the planes are at the same height is given as 6 minutes.
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The expression for the height of the two airplanes in terms of time t is given as,
For the first airplane it is 35400 - 3300t,
And, for the second it is 2600t.
When, the two airplanes are at the same height the following equation can be written,
35400 - 3300t = 2600t
=> 35400 = 3300t + 2600t
=> 5900t = 35400
=> t = 6
