Parameter or Statistic to classify each statement:
1. Statistic
2.Statistic
3. Statistic
4. Parameter
What is parameter and statistic?A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean). The goal of quantitative research is to understand characteristics of populations by finding parameters.
1. 85% of the golf teams surveyed have teammates that can break 80.
This only refers to the surveyed people, so this only refers statistic statement.
2. According to the survey, each member of the soccer team has an average of 2 jerseys.
As in this case, the soccer team is considered as sample then this is a statistic.
3. Of the 28 swim teams surveyed across America, 5 of them practice 10 hours a week.
Here the information is about the sample (only 28 swim teams). So here this is statistic.
4. Basketball teams in the district have won at least 3 games for every 5 they have played
Here the information is about the number of games win, which was taken from whole population in this case this is parameter.

Explain the difference between low and high-frequency waves
Answer:
Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies
What is the slope of the line?
Answer:
The slope of a line characterizes the direction of a line.
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). 7 The measure of angle Ois 4. The measure of its reference angle is °, and tan is
The measure of the trigonometric relations is tan θ = -1 when the reference angle θ = 315°
What is Reference Angle?Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. For angles in the first quadrant, i.e., angles less than or equal to 90 degrees, the reference angle is equal to the original angle.
The reference angle is always positive
0° to 90°: reference angle = angle
90° to 180°: reference angle = 180° - angle
180° to 270°: reference angle = angle - 180°
270° to 360°: reference angle = 360° - angle
Given data ,
Let the reference angle be represented as R
Now , the value of R is R = 315°
And , the measure of angle θ = 7π/4
The reference angle θ = 315°
So , the value of tan ( 315 )° = -1
Hence , the trigonometric value tan ( 7π/4 ) = -1

Answer:
Both ate the same amount of cake, there will be 6/8 or 3/4ths of the cake left.
Step-by-step explanation:
2/16 is equivalent to 1/8. Therefore they ate the same amount of cake.
Answer:
they ate the same amount 1/8 and 2/16 are the same thing.3/4
Step-by-step explanation:
they both ate 1/8 so 8/8-2/8=6/8=3/4 of the cake left

Solve for x: 2(x + 4) + 6 = 12x - 8
Answer:
x = 2.2
Step-by-step explanation:
2(x+4)+6 = 12x-8
Use distribution property
2x+8+6 = 12x-8
Combine like terms
2x+14 = 12x-8
Subtract 14 from both sides
2x = 12x-22
Subtract 12x from both sides
-10x = -22
Divide both sides by negative 10
x = 2.2 or x = 11/5 in fractions.

Answer:
Option D, x² + 4x - 21
Step-by-step explanation:
Using FOIL;
x * x = x²
x * (-3) = -3x
7 * x = 7x
7 * (-3) = -21
Therefore; x² + (-3x) + 7x - 21
=> If simplified:
=> x² + 4x - 21

Answer:
9.3
Step-by-step explanation:
Answer:
The answer is 4 \sqrt{7}.
Step-by-step explanation:
The formula is a\sqrt{x} + b\sqrt{x} = (a+b)\sqrt{x}, but if you don't understand it, here's an easier way to think about it.
You can think of \sqrt{7} as x (or any other variable). Now, the equation is 3x + x. If you've ever done algebra, (you probably have if square roots popped up on your homework) you know that this equals to 4x. Now, replace the x with \sqrt{7}, because we already decided that those two were equal. Therefore, the answer is
4 \sqrt{7}.

Answer:
[tex]x=80^{\circ},\\y=80^{\circ}[/tex]
Step-by-step explanation:
The measure of an angle formed by a secant and a tangent outside of a circle is half of the absolute difference between the two arcs it forms. Therefore, we have the following equation:
[tex]m\angle A=\frac{\widehat{BC}-\widehat{BD}}{2}[/tex]
Substituting given values, we get:
[tex]20=\frac{120-x}{2},\\40=120-x,\\x=\boxed{80^{\circ}}[/tex]
Since there are 360 degrees in a circle, we can write the following equation, using [tex]x[/tex], to solve for [tex]\widehat{DC}[/tex]:
[tex]x+\widehat{DC}+120=360,\\80+\widehat{DC}+120=360,\\\widehat{DC}=\boxed{160^{\circ}}[/tex]
The value of the angle formed by a chord and a tangent is half the measure of the arc it forms. Therefore,
[tex]y=\frac{\widehat{DC}}{2}=\frac{160}{2}=\boxed{80^{\circ}}[/tex]
