A random sample of 50 bottles is selected from the production line of a large manufacturing company. The mean
of the contents of the 50 bottles is 20.25 ounces. The manager of the company requests that the machines be
recalibrated because bottles coming off the production line are supposed to contain 20 ounces. Which of the
following statements is true?
O 20 is a statistic and 20.25 is a statistic.
20 is a statistic and 20.25 is a parameter.
o 20 is a parameter and 20.25 is a statistic.
O 20 is a parameter and 20.25 is a parameter.
Answer: 20 is a parameter and 20.25 is a statistic
Definition of parameter: a numerical characteristic of a population, as distinct from a statistic of a sample.
Definition of statistic: a fact or piece of data from a study of a large quantity of numerical data.
Hope this helps!
Answer:
C
Step-by-step explanation:
20 is a parameter and 20.25 is a statistic

Answer:
Angle A = 30.8
Angle B = 33.2
Step-by-step explanation:
180 - 116 = 64
This means that the other two angles need to add up to 64.
I just plugged in numbers until it worked.
I got that x = 14.6
2x + 4
2(14.6) + 4
29.2 + 4
33.2
3x - 13
3(14.6) - 13
43.8 - 13
30.8
Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.
116 + 33.2 + 30.8 =
180
Angle ABC and angle CBD are complementary. What is the value of x? Record your answer as a whole number.
No links please please please.
Answer:
x=31
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees.
So, 2x+28=90.
To solve:
1. Subtract 28 from both sides
2x=90-28
2x=62
2. Divide both sides by 2
x=62/2
x=31
yeah the picture sums it up, I just dont remember how to do this
Answer and Step-by-step explanation:
To find the length of AB, we have to use Distance Formula.
Distance Formula takes two points on a graph, and puts it into the following formula to calculate the distance between those two points.
The formula:
D = [tex]\sqrt{(x_{2} - x_1)^2 + (y_2 - y_1)^2 }[/tex]
Where:
D = The Distance between two points
[tex]x_2[/tex] = The x value of the second point
[tex]x_{1}[/tex] = The x value of the first point
[tex]y_2[/tex] = The x value of the second point
[tex]y_{1}[/tex] = The x value of the first point
Point A will be the first point and point B will be the second point. All we have to do now is plug those points into the formula and solve.
[tex]\sqrt{(10 - 5)^2 + (0 - 10)^2 }\\\\\\\\\sqrt{(5)^2 + (- 10)^2 }\\\\\\\\\sqrt{25 + 100 }\\\\\\\\\sqrt{125}\\\\\\\\\sqrt{125} = 5\sqrt{5}[/tex]
The length of side AB is [tex]5\sqrt{5}[/tex] units, or 11.18 units.
I hope this helps!

III Question 4 of 10 ( point) Question Attempt: 1 of Unlimited Susan makes house calls. For each, she is paid a base amount and makes additional money for each hour she works, The graph below shows her pay in dollars) versus the number of hours worked. Use the graph to answer the questions.
Answer:
a) $30
b) 30
Step-by-step explanation:
a) Her starting pay is $60. After an hour it goes up to $90. 90-60=30.
b) Every hour, the pay goes up 30. Slope is calculated as the change in y divided by the change in x. That means 30/1, or just 30 is the slope.
On a recent survey, 40% of the 900 people surveyed preferred running.
How many people preferred running?
Answer: 550
Explanation:
Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)
So 900-360
Answer:
360
Step-by-step explanation:
So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.
Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.
And you can check it by multiplying 900 x .40 which would be 360

Television sizes are described by the length of their diagonal measure. What would be the listed size of the TV shown? (To the nearest whole inch)
Answer:
The listed size is 32 inches
Step-by-step explanation:
Given
See attachment for television
Required
The listed size
The listed size is calculated by the diagonal of the television.
This is calculated as using Pythagoras theorem as follows:
[tex]Diagonal^2 = Length1^2 + Length2^2[/tex]
Where:
[tex]Length1 =28in[/tex]
[tex]Length2 =15.7in[/tex]
So, we have:
[tex]Diagonal^2 = 28^2 + 15.7^2[/tex]
[tex]Diagonal^2 = 784 + 246.49[/tex]
[tex]Diagonal^2 = 1030.49[/tex]
Take positive square roots of both sides
[tex]Diagonal = \sqrt{1030.49[/tex]
[tex]Diagonal = 32[/tex] --- approximated
Hence, the listed size is 32 inches

Answer:
B
Step-by-step explanation:
So wiggly, remember that slope is change in y/change in x, or in simpler terms, y/x. Thinking of this, y/x must simplyfy to -3. Or, you can think of it as -3/1.
So know that we have rewrote this as a slope of -3/1, lets use it. Where do we start? Well, we must start at point A, which is at 2 x and 7 y.
Now, going to the RIGHT(+1x) and going DOWN(-3y) we will go from 2x and 7y to 3x and 4y.
Are we on a point yet? Nope, lets do this again.
Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 13x and 4y to 4x and 1y.
Are we on a point yet? Still no, lets try this one more time.
Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 4x and 1y to 5x and -2y.
Are we on a point? YUP. We cna see that point B is at 5x and -2y.
Hope you get it right ;)
Solve for m.
–9 + 6m = –3m − 1 + 10m

Step-by-step explanation:
5.4 Find roots (zeroes) of : F(x) = 2x2 + 1
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 2 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,2
of the Trailing Constant : 1
Final result :
2x • (2x2 + 1) • (5x - 3)

HELP ASAP!!!
a bike rental company charges $12, which includes the first 30 minutes of biking. thereafter, the company charges an additional $0.25 per minute. write a numeric sequence for the first 5 minutes of the 30 minutes.
Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0
The calculation is as follows:
Here we have to divide $12 by 30. That will equal 0.4 a minute.
Now if we add 0.4 for each minutes
So the series be like
0.4 for the first, 0.8 is 2 minute and so on.
