Answer: c six less than twice is the same as two times a number minus six
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
"Twice a number" means a variable/mystery number times 2; aka 2x.
"Six less than" means minus/subtract six.
So, therefore it's 2x - 6.

25. A new app was downloaded 175 times in its first week Since then the number of downloads
increased by 16.5% each week. Use a continuous exponential growth model to approximate
the number of times the app was downloaded in 2 week
37
0/1
37
Answer:
238 times
Step-by-step explanation:
Given
[tex]a = 175[/tex] -- first week
[tex]r = 16.5\%[/tex]--- growth per week
[tex]t = 2[/tex] --- time
Required
The number of times it was downloaded in 2 weeks
An exponential growth is represented as:
[tex]y = a(1 + r)^t[/tex]
So, we have:
[tex]y = 175 * (1 + 16.5\%)^2[/tex]
[tex]y = 175 * (1.165)^2[/tex]
[tex]y = 175 * 1.357225[/tex]
[tex]y = 237.514375[/tex]
[tex]y = 238[/tex] -- approximated
What is the solution to the equation below. Round your answer to two

In x= -2
O A. X=-739
B. x=0.34
O C. X=-0.69
O D. x=0.14
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)

Find the value of AB.

A
E
B
AB = [?]
Answer:
AB = 16
Step-by-step explanation:
The radius of the circle = 10
From the center of the circle to B = 10 (radius)
Since a right angle is formed at point E, we can apply Pythagorean theorem to find EB.
Thus:
EB² = 10² - 6²
EB² = 100 - 36
EB² = 64
EB = √64
EB = 8
EB = AE = 8
therefore,
AB = AE + EB = 8 + 8
AB = 16
Answer:ab=16

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?
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.

Answer:
the answer is A on Edge
A) The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9.
Step-by-step explanation:
took the quiz :)
The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9 is the correct statement.
We have given that,
lim g(x)
X-3
What is the oscillation of the random values?The application of results concerning partial limit laws of normed sums of independent and identically distributed random variables will be obtained.
Therefore from the graph, we can say that option A is correct.

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
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

Select one:
a.
4 liters
b.
25 liters
c.

A. 0
B. 2
C. -2
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.
