1)Find the angle of elevation of the sun from the ground when a tree that is
14ft tall casts a shadow 16ft long. Round to the nearest degrees
Answer:
[tex]\theta=41.18^{\circ}[/tex]
Step-by-step explanation:
Given that,
The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{14}{16}\\\\\theta=41.18^{\circ}[/tex]
So, the required angle of elevation of the sun is equal to [tex]41.18^{\circ}[/tex].
Will give Brainliest and 100 points! Prove the divisibility of the following numbers: 5^5-5^4+5^3 by 7
Answer:
See Below.
Step-by-step explanation:
We have the expression:
[tex]5^5-5^4+5^3[/tex]
And we want to prove that it is divisible by 7.
To do so, we can factor out a 5³ from the expression. This yields:
[tex]=5^3(5^2-5^1+1)[/tex]
Simplify the parentheses:
[tex]=5^3(25-5+1)=5^3(21)[/tex]
We can see that the resulting expression is a value being multiplied by 21.
Since 21 is divisible by 7, our original expression must also be divisible by 7.
Hence proven.

Answer:
4
Step-by-step explanation:
2+3+6+5 is 16 and since there are 4 numbers 16/4 is 4
Answer:
4
Step-by-step explanation:
To find average you must add up all of the numbers and then divide by the amount of numbers there are
2+3+6+5= 16
there are 4 numbers, so you do 16/4
16/4 = 4

According to a survey, about 19% of all Americans are without health insurance. Assume that this estimate is reasonably accurate. Suppose that you select a random sample of 46 Americans. (a) Calculate the expected number of Americans without health insurance in the sample. Answer: (Keep at least four decimal places.) (b) Calculate the standard deviation of the number of Americans without health insurance in the sample. Answer: (Keep at least four decimal places.)
Answer:
a) 8.74
b) 2.6607
Step-by-step explanation:
For each American, there are only two possible outcomes. Either they are without health insurance, or they are not. In the sample, each person is independent of any other person, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
According to a survey, about 19% of all Americans are without health insurance.
This means that [tex]p = 0.19[/tex]
Suppose that you select a random sample of 46 Americans.
This means that [tex]n = 46[/tex]
(a) Calculate the expected number of Americans without health insurance in the sample.
[tex]E(X) = np = 46*0.19 = 8.74[/tex]
(b) Calculate the standard deviation of the number of Americans without health insurance in the sample.
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{46*0.19*0.81} = 2.6607[/tex]

Answer:
x=4 z=117
Step-by-step explanation:
Answer:
x = 4, z = 117
Step-by-step explanation:
14x + 7 and 63 are vertically opposite angles and are congruent, then
14x + 7 = 63 ( subtract 7 from both sides )
14x = 56 ( divide both sides by 14 )
x = 4
z and 63 are adjacent angles and are supplementary, then
z + 63 =180 ( subtract 63 from both sides )
z = 117

Choose the correct statement below. because the value is a numerical measurement describing a characteristic of a . because the value is a numerical measurement describing a characteristic of a . because the value is a numerical measurement describing a characteristic of a . because the value is a numerical measurement describing a characteristic of a .
Complete question :
Determine whether the underlined number is a statistic or a parameter.
"In a study of all 4841 students at a college, it is found that 55% own a computer."
Answer:
because the value is a numerical measurement describing a characteristic of a population.
Step-by-step explanation:
The difference between statistic and parameter lies in the fact that, statistics are used in describing the numerical value obtained from a sample of data. While parameter are used to describe the numerical characteristics of a population.
Hence, all students of a college refers to the population(entire students). Therefore, the numerical characteristics obtained from such data would be called a parameter.

What is -1
What is the answer
Answer:
1
Step-by-step explanation:
The answer is actually just positive 1.
Absolute value is the direct opposite of a number with a positive value on a number line. However, the absolute value is always answered in a positive form of the number meaning that no matter what the number is (even if it's a positive number) the answer will always be that same number, but in positive form.
Remember, if a number is in between two of these " | " then the answer will be that same number but in positive form.

Answer:
3x - 4y = -4
Step-by-step explanation:
When you put co-ordinate in it then give zero
3(-4)-4(-2)+3=0
3x-4y=-4 equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is 3x - 4y = 7
Convert it to slope intercept form
-4y = 7 - 3x
4y=-7+3x
y=-7/4+3/4x
y=3/4x-7/4
3/4 is the slope and the parallel line should also have the same slope.
Now equation of line passing through (-4, -2)
-2=3/4(-4)+b
-2=-3+b
-1=b
So y=3/4x-1
3x-4y=-4 is another equation represents the line which is parallel.
Hence, 3x-4y=-4 equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).

The population of weights for men attending a local health club is normally distributed with a mean of 172-lbs and a standard deviation of 27-lbs. An elevator in the health club is limited to 34 occupants, but it will be overloaded if the total weight is in excess of 6222-lbs. Assume that there are 34 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded
Answer:
The average weight beyond which the elevator would be considered overloaded is 183 lbs.
Step-by-step explanation:
Weight in excess of 6222 lbs means that the elevator is overload.
With 34 men:
Average weight greater than:
6222/34 = 183 lbs
The average weight beyond which the elevator would be considered overloaded is 183 lbs.
