Answer:
n=2.5
Step-by-step explanation:
First, write an equation!
n+5n-6+2n+1=15
Now, combine like terms to make things easier.
8n-5=15
Cancel -5 from the left to isolate 5n as a variable.
8n-5+5=15+5
8n=20
Now divide both sides by 8.
8n/8=20/8
n=2.5
Suppose the mean value of a population is 51, and many samples are taken from the population. As the size of each sample increases, the mean of the sample means would approach which of the following values? A. 48 B. 54 C. 51 D. 45
Answers
The mean of the sample means would approach the following value:
C. 51.
What is defined by the Central Limit Theorem?The Central Limit Theorem defines the distribution of the sampling distribution of sample means with size n of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex].
For the sampling distribution, the mean and the standard deviation are given as follows:
Mean: [tex]\mu[/tex], that is, the same as the population mean.Standard deviation: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex], which is the population standard deviation divided by the square root of the sample size.The mean of the sample means should be approximated to the population mean, hence it is given by 51.

A botanist measures a plant, in feet, at the beginning of each month and notices that the measurements form a
geometric sequence, as shown below.
2, 2.2, 2.42, 2.662, ...
If the first measurement was taken on September 1, about how tall was the plant three months before, on June 1,
assuming the same growth pattern?
0.9 ft
1.5 ft
1.7
2.0 ft
Answers
Answer:
1.5ft , B for EDGE2020
Step-by-step explanation:
they are being multiplied by 1.1, so if you divide 1.1 down from 2 three times you get 1.5 roughly.
Using a geometric sequence, it is found that the plant's height on June 1 was of 1.5 ft.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, we have that the first term and the common ratio are given, respectively, by:
[tex]a_1 = 2, q = \frac{2.2}{2} = 1.1[/tex]
Hence the rule for the nth term is given by:
[tex]a_n = 2(1.1)^{n-1}[/tex]
June 1st would be equivalent to three months before the term 1, hence it is the term 1 - 3 = -2, then:
[tex]a_{-2} = 2(1.1)^{-3} = 1.5[/tex]
The plant's height on June 1 was of 1.5 ft.

Answer:
32 meters
Step-by-step explanation:
1 inch=4 meters
4(meters)x8(inches)=32 meters
======================================================
Work Shown:
(height on paper)/(real height) = scale factor
(8 inches)/(x meters) = (1 inch)/(4 meters)
8/x = 1/4
8*4 = x*1 .... cross multiply
32 = x
x = 32 meters
---------------------
Another way to get the answer
1 inch = 4 meters
8*(1 inch) = 8*(4 meters) ... multiply both sides by 8
8 inches = 32 meters
---------------------
Whichever method you use, you'll get 32 meters as the answer.

Find the largest open interval where the function is increasing. correct answer will get brainliest
Answers
Answer:
Correct answer: C. (1,∞)
Step-by-step explanation:
First Derivative
Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.
If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.
The function to analyze is:
[tex]f(x)=x^2-2x+1[/tex]
Computing the first derivative:
[tex]f'(x)=2x-2[/tex]
The function will be increasing when:
[tex]2x-2>0[/tex]
Dividing by 2:
[tex]x-1>0[/tex]
Solving:
x > 1
This solution is represented by the interval (1,∞)
Correct answer: C. (1,∞)

Mental accounting can be used to explain(A) higher savings in separate retirement accounts;(B) high willingness to spend on credit cards;(C) holding depreciating stocks longer than appreciating ones;(D) all of the above.
Answers
Answer:
(D) all of the above.
Step-by-step explanation:
Mental accounting refers to this ability to organize your budget, to think about your money by separating it into different expenditure items. Your brain differentiates money based on how you got it and how you plan to spend it. In other words, you are creating some sort of mental piggy bank where you put your money which will be used for such and such an expense.
Mental accounting can be used to explain how higher savings are derived with various retirement accounts; how high clients purchasing a particular product are willing to spend on credit cards and also explains why brokers hold depreciating stocks longer than appreciating ones due to the mental thought that such depreciating stock will rise at a future time.
