Answer:
The sign of each y-coordinate changed.
Step-by-step explanation:
This was a reflection over the x-axis.
If you look at point F, it is (-5, -1) the corresponding point F' is (-5,1). Notice the numerical values of x and y are the same, but the sign of y flipped from negative to positive. The other four points all follow the same pattern.

Answer:
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.)

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:

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:

A study has been done to test the effect of rock music on auditory attention. Eighteen eighth-grade students are randomly divided into two groups of 9 students, and the same hearing test was given to these students. The first group of students listened to rock music for 25 minutes right before taking the test, and the other group of students took the test without listening to the music. Here are their scores.
Group with music: 78 85 87 93 97 80 94 88 86
Group without music: 64 66 77 84 63 72 85 79 80
Assume normal populations with equal variance and construct a 95% confidence interval for the mean difference.
Find the lower bound of the confidence interval (round off to the nearest integer).
Answer:
The Lower bound of the confidence interval to the nearest integer = 6
Step-by-step explanation:
Calculate the Lower bound of the confidence interval
First step : Calculate the mean and standard deviation for each groups
Group 1 ( group with music )
N = 9
Total ( ∑x ) = 788
mean = 788 / 9 = 87.55
Variance ( s^2 ) = 39.777
s = [tex]\sqrt{39.77}[/tex] = 6.31
Group 2 ( group without music )
N = 9
∑x = 670
mean = 670 / 9 = 74.44
variance ( s^2 ) = 72.27
s = [tex]\sqrt{72.27}[/tex] = 8.50
Next : Calculate the pooled variance , standard error and confidence interval
Pooled variance ( Sp^2 ) : 896.43 / 16 = 56.03
standard error : S ( M1 - M2 ) = √((56.03 / 9) + (56.03 / 9)) = 3.53
confidence interval : μ1 - μ2 = ( M1 - M2 ) ± Ts ( M1 - M2 )
= 13.1111 ± (2.12 * 3.53 )
= ( 5.630 , 20.591 )
The Lower bound of the confidence interval to the nearest integer = 6
