B. x=0.34
O C. X=-0.69
O D. x=0.14
Answers
Answer:
B. x = 0.14
Step-by-step explanation:
Inx = -2
x = e^(-2)
x = 0.135
x = 0.14 (to two d.p)
The solution of the equation ln x =-2 is 0.14
The correct option is (D)
What is logarithm?Logarithms are the inverse of exponents.
Given that:
ln x =-2
Shifting the log on the right side, it will become exponential
x = [tex]e^{-2}[/tex]
x = 0.135
x = 0.14 (two decimal places)

The passing yards for the top 5 quarterbacks in the country are 3,832, 3,779, 3,655, 3,642, and 3,579. Find the variance and standard deviation. Round to the nearest hundredth. EXPLAIN WORK
Answers
First get the average passing yards:
(3,832 + 3,779 + 3,655 + 3,642 + 3,579) / 5 = 3,697.4
Now get the squared residuals for each quarterback's passing yards. That is, compute the difference between each data and the average, then square the result. For example,
(3,832 - 3,697.4)^2 = 134.6^2 = 18,117.2
For the others, you should get squared residuals of
6,658.56
1,797.76
3,069.16
14,018.6
Take the sum of the squared residuals, then - since this is a sample, and not a population of all quarterbacks - divide the sum by 5 - 1 = 4 to get the variance:
(18,117.2 + 6,658.56 + 1,797.76 + 3,069.16 + 14,018.6)/4 = 10,915.3
The standard deviation is just the square root of the variance:
√(10,915.3) ≈ 104.48

the answer is 3697.4

The length of time required for the periodic maintenance of an automobile or another machine usually has a mound-shaped probability distribution. Because some occasional long service times will occur, the distribution tends to be skewed to the right. Suppose that the length of time required to run a 5000-mile check and to service an automobile has mean 1.4 hours and standard deviation .7 hour. Suppose also that the service department plans to service 50 automobiles per 8-hour day and that, in order to do so, it can spend a maximum average service time of only 1.6 hours per automobile. On what proportion of all workdays will the service department have to work overtime?
Answers
Solution :
Mean time for an automobile to run a 5000 mile check and service = 1.4 hours
Standard deviation = 0.7 hours
Maximum average service time = 1.6 hours for one automobile
The z - score for 1.6 hours = [tex]$\frac{1.6-1.4}{0.7 / \sqrt{50}}$[/tex]
= 2.02
Now checking a normal curve table the percentage of z score over 2.02 is 0.0217
Therefore the overtime that will have to be worked on only 0.217 or 2.017% of all days.
Shannon went to an auto repair shop and paid $339.50, which included parts that cost $112 and 3.5 hours of labor. Joni went to an auto repair shop and paid $455, which included parts that cost $310 and 2.5 hours of labor. Which correctly compares the cost of the labor? Shannon paid $7 more per hour for labor. Shannon paid $7 less per hour for labor. Joni paid $85 more per hour for labor. Joni paid $85 less per hour for labor.
All the answers given are incorrect. The correct answer should be Shannon paid $7 more for labor.
Answers
Answer:
Option A, Shannon paid $ 7 per hour to labor than Joni
Step-by-step explanation:
Total amount paid by Shannon = $339.50
Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)
Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5
Total cost of 1 hours of labor paid by Shannon $65 per hour
Total amount paid by Joni = $455
Total cost of 2.5 hours of labor paid by Joni = $455- $$310
Total cost of 1 hours of labor paid by Joni = $145/2.5
Total cost of 1 hours of labor paid by Joni = $ 58
Hence, Shannon paid $ 7 per hour to labor than Joni

A recent math test results show a mean of 75 and a standard deviation of 3. A random test is chosen with a raw score of 86. Which of the following tests scores is better than what percentage of all scores?
TEST 1: x=65, μ=70, σ=3
TEST 2: x=80, μ=50, σ=10
A) Test 1 has the highest z-score
B) Test 2 has the highest z-score
C) Neither, the original test has a z-score 3.67 which is the highest z-score.
Answers
Answer:
c
Step-by-step explanation:
The test which scores are better than the percentage of all scores will be tested 2 and the percentage is 3. Hence, option B is correct.
What is Normal distribution?A probability distribution that is symmetric around the mean and demonstrates that data close to the mean are more likely to occur than data distant from the mean.
As per the given information in the question,
1.
x = 65
Mean, μ = 70
Standard deviation, σ = 3
Use the equation given below to find the percentage,
Z = (x - Mean)/Standard deviation,
Z = (64 - 70)/3
= -6/3
Z = -2
2.
x = 80
Mean, μ = 50
Standard deviation, σ = 10
Use the equation given below to find the percentage,
Z = (x - Mean)/Standard deviation,
Z = (80 - 50)/10
= 30/10
Z = 3
Compare the values obtained, and it is clear that Test 2 got height score.

A. 0
B. 2
C. -2
Answers
Answer:
B
Step-by-step explanation:
You can read this as "find g of f of 2"
Also written as g(f(2)).
What we're doing is is looking at the function f and getting the value when you input 2. f(2)
Since the function f is the curved one, you will find the coordinate where the input is 2. At input 2 or x=2, we get the value of 0.
Now back to g(f(2)) -- Because we have found the value of f when it is 2, we can replace this equation with:
g(0)
Now we find the value we get from g when we put 0 as the input. When 0 is our input, or when our x is 0, we see the point of g is (0,2) so our output is 2.
