Answer:
x = 12.5
Step-by-step explanation:
From the diagram,
Applying
tanФ = Opposite/Adjacent...................... Equation 1
From the diagram,
Given: Opposite = 16, Adjacent = x, Ф = 52°
Substitute these values into equation 1
tan52° = 16/x
make x the subject of the equation
x = 16/tan52°
x = 16/1.27994
x = 12.5.

Number of year = 25 year and 7 month (Approx.)
Step-by-step explanation:
Given:
Amount deposit = $200,000
Future amount = $1,000,000
Rate of interest = 6.5%
Find:
Number of year
Computation:
Using compound amount formula;
A = P[1+r]ⁿ
1,000,000 = 200,000[1+6.5%]ⁿ
1,000,000 / 200,000 = [1+6.5%]ⁿ
5 = [1+0.065]ⁿ
n = 25.557
Number of year = 25.557
Number of year = 25 year and 7 month (Approx.)

[tex]RHS=2(3)^2+2(4)^2+2(5)^2+2(6)^2+2(7)^2[/tex]
[tex]RHS=2(9)+2(16)+2(25)+2(36)+2(49)[/tex]
[tex]RHS=18+32+50+72+98[/tex]
[tex]RHS=270[/tex]

3. What are a few ways that Alana can get a better understanding of her spending patterns?
Answer:
Step-by-step explanation:
A certain test preparation course is designed to help students improve their scores on the USMLE exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 5 students' scores on the exam after completing the course: 14,11,18,9,19 Using these data, construct a 99% confidence interval for the average net change in a student's score after completing the course. Assume the population is approximately normal. Step 3 of 4: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
The critical value is [tex]T = 4.604[/tex].
The 99% confidence interval for the average net change in a student's score after completing the course is (6.236, 22.164).
Step-by-step explanation:
The first step to solve this question is finding the sample mean and sample standard deviation:
14,11,18,9,19
Sample mean is sum of all values divided by the number of values. Thus:
[tex]\overline{x} = \frac{14+11+18+9+19}{5} = 14.2[/tex]
The sample standard deviation is the square root of the division of the sum of the subtractions squared of each value and the mean, and the number of values. Thus:
[tex]s = \sqrt{\frac{(14-14.2)^2+(11-14.2)^2+(18-14.2)^2+(9-14.2)^2+(19-14.2)^2}{5}} = 3.868[/tex]
Confidence interval:
We have the standard deviation for the sample, and so we use the t-distribution to build the confidence interval.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 5 - 1 = 4
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 4 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 4.604.
The critical value is [tex]T = 4.604[/tex].
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 4.604\frac{3.868}{\sqrt{5}} = 7.964[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 14.2 - 7.964 = 6.236.
The upper end of the interval is the sample mean added to M. So it is 14.2 + 7.964 = 22.164.
The 99% confidence interval for the average net change in a student's score after completing the course is (6.236, 22.164).
Place the following events in sequence:
A) Your body begins overheating;
B) Nerves and hormones communicate with the hypothalamus;
C) You begin sweating
Answer:
acb
Step-by-step explanation:
Place the following events in sequence:
Your body begins overheating;You begin sweatingNerves and hormones communicate with the hypothalamus;.What is Nerve cells?Nerve cells, also known as neurons, are "excitable" cells that can convert different stimuli into electrical signals by sending continuous sequences of information about the internal and external environment to the central nervous system (CNS).
These are found all over the body but are particularly concentrated in the brain and spinal cord. The nervous system is built on nerves as well as the brain and spinal cord.
The nervous system sends information from the brain and spinal cord to the rest of your body, so if part of this system is damaged, these signals can't be transmitted effectively which leads to balance problems and falls.
Thus, the following events in sequence:
Your body begins overheating;You begin sweatingNerves and hormones communicate with the hypothalamus;.Learn more about Nerve cells, here:

Find the area of the shape shown below.
Answer:
8 units²
Step-by-step explanation:
What you have is a square with two triangles. We will break them apart, calculate the area and then add them together.
Square: A = l · w
2 · 2 = 4 un²
Triangle: A = (b · h) ÷ 2
(2 · 2) ÷ 2 = 2 un²
4 un² + 2 un² + 2 un²
8 un²

What is union and intersection of sets?The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the universal set be represented as U
where the value of U is
U = {x|x is a rational numbers}
And , let the second set be represented as S,
where S = {x|x is an integer}
Now , the compliment of set S is given by = S'
And , S' = 1 - S
On simplifying , we get
S' = 1 - {x|x is an integer} and it belongs to U
So , S' = {x|x is a rational non-integer}
Hence , the set is S' = {x|x is a rational non-integer}
