Answer:
[tex]\=x=82[/tex]
Step-by-step explanation:
From the question we are told that:
Data
[tex]\begin{center}\begin{tabular}{ |c|c|c|c|c|c| } 87& 91& 86& 82& 72&91 \\ 60& 77& 80& 79& 83&96 \end{tabular}\end{center}[/tex]
Generally the equation for Point estimate [tex]\=x[/tex] is mathematically given by

What is the value of the expression below?
64^1/3
Answer:4
Step-by-step explanation:
Just did this question
This question confuses me, and I am not understanding it.
Answer: As n increases, p increases.
The question is asking you about the equation of a line, p=2n-10
The equation of a line is y=mx+b
In this equation, m is the slope (how much you go up or down and then over)
In this equation, b is the y-intercept (where it intersects with the y line at 0)
Now with this knowledge, p=2n-10
P stands for y and N stands for x (its the same thing even if different)
2n means the m=2
Since the slope is positve it goes up 2 and then right 1
The y-int is -10
Now the options want to know what happens as n increases
Since the slope is positive when the x increases you know that the y increases so
As n increases, p increases.
(also i attached what the graph looks like)
I hope this explanation could help, please let me know if you do not understand still and if you could mark brainliest I would greatly appreciate it.
Answer: as n increases p increases

Beetles may be the most varied order of animals. New beetle species are authenticated, completely unpredictably, at a typical rate of one every 7.0 months. A supplement to a guide is planned to be published after 20 new species have been discovered. a) What are the expected value and standard deviation of the number of months (treated as a continuous measure of time) until the supplement is published
Answer:
The mean until the supplement is published is 140 months, while the standard deviation is of 11.8 months.
Step-by-step explanation:
The Poisson distribution is used to solve this question, as we have only the mean. In this distribution, the standard deviation is the square root of the mean.
In this question, we have that:
Species are discovered at a rate of once every 7 months.
A supplement to a guide is planned to be published after 20 new species have been discovered.
a) What are the expected value and standard deviation of the number of months (treated as a continuous measure of time) until the supplement is published?
Mean is: 7*20 = 140 months.
Standard deviation is [tex]\sqrt{140}[/tex] = 11.8 months.
The mean until the supplement is published is 140 months, while the standard deviation is of 11.8 months.

For angle A between sides b and c, the law of cosines formula can be solved to find the angle as ...
A = arccos((b² +c² -a²)/(2bc))
When calculations are repetitive, I find a spreadsheet useful. It doesn't mind doing the same thing over and over, and it usually makes fewer mistakes.
Here, the side opposite x° is put in column 'a', so angle A is the value of x. The order of the other two sides is irrelevant.
__
Additional comment
The spreadsheet ACOS function returns the angle in radians. The DEGREES function must be used to convert it to degrees. The formula for the first problem is shown here:
=degrees(ACOS((C3^2+D3^2-B3^2)/(2*C3*D3)))
As you can probably tell from the formula, side 'a' is listed in column B of the spreadsheet.
The spreadsheet rounds the results. This means the angle total is sometimes 179.9 and sometimes 180.1 when we expect the sum of angles to be 180.0.
Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write with their left hand is equal to 0.32. Which of the following is a type I error? A. Reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32. B. Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32. C. Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32. D. Reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32.
Answer:
Type 1 error :
D. Reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32.
Type 11 error :
C. Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32.
Step-by-step explanation:
A type 1 error is committed when a true null rejected. That is an incorrect rejection of a true null. Hence, by rejecting the claim that proportion ofbpop
Type 2 error is made when a false null is adopted. Here, we fail to reject a false null. In the scenario above, type 11 error will be made if we fail to reject the claim that proportion of People who write with their left hand is 0.32, when the proportion is correctly not 0.32

20 Here is a list of five numbers.
98^53
98^64
98^73
98^88
98^91
Find the lowest common multiple of these five numbers.
We want to five the lowest common multiple of these 5 numbers. We will see that the lowest common multiple is:
[tex]98^{91}[/tex]
A multiple of a number N is any product between N and a positive integer. Here we want to get the smallest common multiple of the 5 numbers in the given set.
Here, the set is:
[tex]{98^{53}, 98^{64}, 98^{73}, 98^{88}, 98^{91}[/tex]
Remember the rule:
[tex]a^n*a^m = a^{n + m}[/tex]
Then we can see that:
[tex]98^{91} = 98^{91}*1 = 98^{88}*98^{3} = 98^{73}*98^{18} = 98^{64}*98^{27} = 98^{53}*98^{38}[/tex]
So:
[tex]98^{91}[/tex]
Is a common multiple of all the numbers in the set, and is the smallest common multiple because is equal to the largest number in the set.

Dilation involves changing the size of a figure
The endpoints of the image are (-2,-1) and (6,1)
How to determine the coordinates of the imageThe coordinates of the pre-image are give as:
(2,2) and (6,2)
The scale factor is given as:
k = 2
The center of dilation is given as:
(a,b) = (6,5)
The coordinates of the image are then calculated as:
[tex](x,y) \to (k(x -a) + a, k(y -b) + b)[/tex]
For (2,2), we have:
[tex](x,y) \to (2(2 -6) + 6, 2(2 - 5) + 5)[/tex]
[tex](x,y) \to (-2, -1)[/tex]
For (6,2), we have:
[tex](x,y) \to (2(6 -6) + 6, 2(2 - 5) + 5)[/tex]
[tex](x,y) \to (6, -1)[/tex]
Hence, the endpoints of the image are (-2,-1) and (6,1)

What is the perimeter, in units, of the model?
A. 32x + 12
B. 46x + 25
C. 50x + 11
D. 64x + 24
Answer:
the answer is c 50x +11
Step-by-step explanation:
The Perimeter of the model is (50x + 11).
What is Perimeter?A shape's perimeter is calculated mathematically using the idea of perimeter. You sum together the lengths of all the sides to find the perimeter.
We have,
The two sides of the triangle are 6x - 4 units each.
The length of the rectangle is 14x + 13.
The width of the rectangle is 12x + 3.
So, the perimeter of the house
= (6x -4) + (14x + 13) + (12x + 3) + 12x + 3 + 6x -4
= 50x + 11
Thus, the perimeter is 50x + 11.
