Suppose that a sample is taken from a population whose mean value is 76.
As the sample size increases, the sample mean will approach which value?
Answer:
The sample mean will approach 76
Step-by-step explanation:
Refer to Law of large numbers (LLN) and the central limit theorem (CLT)
For random sample, with sample size n, in population with expected value μ, the sample mean converge almost surely to the expected value μ as n -> ∞

17. - 12 - ( + 8) =
18. 15 - 9=
19. - 5 - (-8)=
20. - 11 - ( + 14 ) =
Answer:
16. 9 - (-5) = 21.9
17. -12 - ( + 8) = -4
18. 15 - 9 = 6
19. -5 - (-8)= 3
20. -11 - ( + 14 ) = -25
Step-by-step explanation:
Subtracting a negative from another number is the same as adding the number. Thus, 16.9 - (-5) = 16.9 + 5.
Hope it helps <3 :)
Answer:
16.9-(-5)=21.9
17.-12-(+8)= -3

Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
1) know your grams and centigrams!
1 Grams = 100 Centigrams
2) If you want to find the centigrams, all you gotta do is; multiply the gram to 100.
For example: This bar of chocolate has 100 grams of sugar. I wonder what is the mass in centigrams?
100 grams * 100 centigrams = 1,000 Centigrams.
3) To answer your question; multiply 347 by 100!
347 * 100 = 34,700 centigrams.
Hope this helps!
(06.04 HC) The graph shows Wilson's science scores versus the number of hours spent doing science homework. A graph titled Wilsons Science Scores shows Hours of Practice in a Week on x axis and Science Scores on y axis. The x axis scale is shown from 0 to 5 at increments of 1, and the y axis scale is shown from 0 to 50 at increments of 5.The ordered pairs 0, 15 and 0.5, 18 and 1, 18 and 1.5, 25 and 2, 30 and 2.5, 35 and 3, 40 and 3.5, 43 and 4, 41 and 4.5, 45 and 5, 48 are shown on the graph. A straight line joins the ordered pairs 0, 14.9 and 5, 50. What will most likely be Wilson's approximate science score if he does science homework for 6 hours a week? (5 points) Group of answer choices 33 points 42 points 52 points 55 points
Answer:
The answer 55
Step-by-step explanation:
Because it goes up by five for they gave us the amount of point they get for 5 hours and the amount of point he had for 5 hours was 50 so we just needed to add 5 more and 50+5= 55
I don't know if I made myself clear but good luck! :)
Answer
Personally I think it's 55 as well!

What is the area of this parallelogram
Answer:
B. 12.25
Step-by-step explanation:
A=bxh=3.5·3.5=12.25
Answer:
17.15
Step-by-step explanation:
There are 2 ways to solve this.
One way is this:
Add 1.4 and 3.5 together to get the total length of the parallelogram. The sum would be 4.9. Then multiply this number by the height of the figure(3.5cm). So that the product of 4.9 and 3.5 is 17.15.
The second way is this:
Find the area of the two triangles and the square and then add those products together. So add:
1.4 x 3.5 ÷21.4 x 3.5 ÷23.5 x 3.5So solve this equation and you will get:
2.45 + 2.45 + 12.25=17.15Hi can someone please answer and explain all you work thank you! I’ll mark brainliest

Find the area of the triangle
Answer:
[tex]\sqrt{20}\ or\ 2\sqrt{5}[/tex]
Step-by-step explanation:
Which of the following pairs of ratios are equivalent?
1) 38 : 133 and 16 : 56 , 2) 15 : 20 and 28 : 56
Answer:
38 : 133 and 16 : 56 are equivalent
Step-by-step explanation:
Given
1) [tex]38 : 133[/tex] and [tex]16 : 56[/tex]
2) [tex]15 : 20[/tex] and [tex]28 : 56[/tex]
Required
Determine which is equivalent
1) [tex]38 : 133[/tex] and [tex]16 : 56[/tex]
[tex]Ratio = 38 : 133[/tex]
Divide by 19
[tex]Ratio = 2:7[/tex] --- can't be further simplified
[tex]Ratio = 16 : 56[/tex]
Divide by 8
[tex]Ratio = 2:7[/tex]
Hence:
[tex]38 : 133[/tex] and [tex]16 : 56[/tex] are equivalent
2) [tex]15 : 20[/tex] and [tex]28 : 56[/tex]
[tex]Ratio = 15 : 20[/tex]
Divide by 5
[tex]Ratio = 3 : 4[/tex]
[tex]Ratio = 28 : 56[/tex]
Divide by 28
[tex]Ratio = 1:2[/tex]
Hence, both are not equivalent.

kate pays $203 in advance on her account at the athletic club. Each time she uses the club, $9 is deducted from the account. Find the remaining in the account after 12 visits
Answer:
95
Step-by-step explanation:
The equation to solving this would be 203 - (9 multiply 12). If you multiply 9 and 12 you get 108. Minus 108 from 203 and you get 95.
What is the percent of decrease from 20 to 19?
Answer: 5%

The figure of y = x will be a straight line with slope 1 and they ;lie in the first quadrant and the third quadrant.
What is Linear Function?A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables but does not have exponents to the variables or the exponent of the variable is 1.
We have to choose 5 ordered pairs first whose first and second coordinate are equal.
Let the coordinates be (-4, -4), (-2, -2), (0, 0), (2, 2) and (4, 4).
The ordered pairs are of the form (x, x), that both the coordinates have same value.
So we get a linear function y = x
The graph of a linear function will be a straight line.
Since y = x, the graph will be a straight line which tends to the positive direction and the slope of the line = 1.
That is , the angle that the line making with the X axis is 45°.
And the figure lies on first and third quadrant.
Hence the figure of y = x would be a straight line with slope 1.

Answer obtained by graphing the formula.
Element X decays radioactively with a half life of 9 minutes. If there are 760 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 19 grams?
Answer:
Step-by-step explanation:
760·0.5^(t/9) = 19
0.5^(t/9) = 19/760
2^(-t/9) = 0.025
-t/9 = log₂(0.025)
t = -9log₂(0.025) = 47.9 minutes
Answer:
47.9 minutes

In the year 2001, a person bought a new car for $15500. For each consecutive year after that, the value of the car depreciated by 5%. How much would the car be worth in the year 2005, to the nearest hundred dollars?
Answer:
$12,000.
Step-by-step explanation:
Given that in the year 2001, a person bought a new car for $ 15500, and for each consecutive year after that, the value of the car depreciated by 5%, to determine how much would the car be worth in the year 2005, to the nearest hundred dollars, the following calculation must be performed:
100-5 = 95
15,500 x 0.95 x 0.95 x 0.95 x 0.95 x 0.95 = X
14.725 x 0.95 x 0.95 x 0.95 x 0.95 = X
13,988.75 x 0.95 x 0.95 x 0.95 = X
13,289.3125 x 0.95 x 0.95 = X
12,624.846875 x 0.95 = X
11.993.60453125 = X
Thus, to the nearest hundred dollars, the cost of the car after 5 years will be $ 12,000.
