Hi there!
To write a equation of a graph, we must follow the formula y = mx + b, where m is the slope and b is the y-intercept. In this scenario, we can utilize this formula to get our answer. First, let's take a look at the y-intercept. To find this, we need to take a look at the graph. We can see that the line crosses the y-axis at the point (0,250). Hence, 250 will be our y-intercept. Now, we can move on to the slope. This can be found by first taking two points from our graph. Here are the two points I'll be using - (0,250)(2,200). Now, use the slope formula, which goes as m = y₂ - y₁ / x₂ - x₁. All we have to do is plug in the respective values from the coordinate points. We get -
m = 200 - 250 / 2 - 0
m = -50 / 2
m = -25
Using the information we have derived, we can construct the equation y = -25x + 250. Usually, the answer should be written in standard form, which goes as Ax + By = C, where A, B, and C are numbers. Therefore, to derive y = -25x + 250 into standard format, we must add 25x to both sides. This gives us y + 25x = 250. Hope this helped and have a marvelous day!
Answer:
Degree of freedom = 19
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 20
For a t-test hypothesis it was claimed that the population mean is greater than 89 second.
1) df
Df denotes the degree of freedom.
- The Degrees of Freedom refers to the number of values involved in the calculations that have the freedom to vary.
2) Degree of freedom = n - 1
where n is the sample size
Degree of freedom = 20 - 1 = 19
The first thing you should do is to add -2q on both sides of the equation and then add +7 on both sides so you will have:
6q - 2q = 29 +7
4q = 36 so q is equal to 36/4 or 9 :)))
i hope this is helpful
have a nice day
To solve this, we divide 48 by 3.
48÷3=16
