Answer:
- Statistics;
- Parameter;
- Statistics;
- Parameter.
Step-by-step explanation:
According to southeastern.edu,
- parameters summarize data from an entire population, whereas
- statistics summarize data from a sample of the population.
The first statement is true for the sample "those surveyed" the population but not necessarily the entire population. Statistic.
The second statement implies that the soccer team is the population. All members of the population are surveyed. Parameter.
The third statement states that a sample of 100 of all swimming teams are surveyed. Statistic.
The fourth statement implies that the population is all members of the golf team, and that all members of the population are surveyed. Parameter.
Answer:
I'm notttt sureeeeee I think its C i don't know,
Answer:
y = 2x - 3
Step-by-step explanation:
Step 1: Find the slope. You find the slope by using the formula y2-y1/x2-x1. (2, 1) and (4, 5) are our points. Let's find our values.
y2= 5
y1= 1
x2 = 4
x1 = 2
Plug in the numbers into the equation. 5 - 1 is 4. 4 - 2 is 2. 4/2 is 2. There. Our slope is 2.
Step 2: Find the b value. Keep in mind that an equation in point-slope form is y = mx + b, where m = the slope, and b = the y-intercept. For this part, you will plug in one of the points as x and y to find the b value. let's use point (4, 5)
The equation then becomes 5 = 2(4) + b. As we know, 2 * 4 is 8. Subtract 8 on both sides of the equation to cancel out the right side and isolate the b variable. 5 - 8 is -3. Even if you use the other point for the equation (1 = 2(2) +b), you should get the same answer of -3.
Answer:
This equation is in standard form, so to make graphing easier you need to put it in y=mx+b form or slope, intercept form.
Step-by-step explanation:
I have attached a photo of what the graph would look like.
However, in the future you should know how to turn this into a slope intercept equation.
-2x+7y=-21
+2x +2x
7y=2x-21
divide the entire equation by 7
y= 2/7x-3
That is a full equation in slope intercept form.
Hopefully this helps!
