Answer:
The points are randomly scattered with no clear pattern
The number of points is equal to those in the scatterplot.
Step-by-step explanation:
The points in the residual plot of the line of best fit that is a good model for a scatterplot are randomly scattered with no clear pattern (like a line or a curve).
The number of points in the residual plot is always equal to those in the scatterplot.
It doesn't matter if there are about the same number of points above the x-axis as below it, in the residual plot.
The y-coordinates of the points are not the same as the points in the scatterplot.
Answer:
He'll need 288 cups to make a waffle on his 24 foot diameter circular griddle.
Step-by-step explanation:
In order to find out how much batter Danny needs we first need to compute the area of the first pans, since it is a circular pan their area is given by A = 2*pi*r. So we have:
Area of the first pan = 2*pi*(6/2) = 18.84 square inches
Area of the second pan = 2*pi*(24/2) = 75.36 square foots
We now need to convert these values to be in the same unit, we'll convert from square foots to square inches:
Area of the second pan = 75.36 * (12)^2 = 10851.84 square inches
We can now use a proportion knowing that the batter and the thickness of the waffles are the same. If 0.5 cup of flour can make a waffle on 18.84 square inches then x cup of flour can make a waffle on 10851.85 square inches. Writing this in a mathematical form, we have:
0.5/x = 18.84/10851.84
18.84x = 0.5*10851.85
x = 10851.85*0.5/18.84 =288 cups
Answer:
Scalene triangle
Step-by-step explanation:
scalene triangle is a triangle where the lengths of all three sides are different, it comprises of both obtuse and acute angles,all giving a sum of 180 degrees
We are given with
x1 = 20 min
s1 = 2 min
x2 = 30 min
s2 = 4 min
p = 0.9
Condition (x > 25)
We need to get the t-value between the two means and comparing it wit the t-value for the time of 25 minutes given that there is a 90% probability that the weather will be good. Simply use the t-test formula and use the t-test table to get the probability.
PART 1: Identify the slope of the graphed line
To find the slope, I will use the slope formula: m = (y₂ - y₁) / (x₂ - x₁) using the points (0, 1) & (3, 0).
m = (0 - 1) / (3 - 0)
m = - 1 / 3
The slope of the graphed line is negative one-third: - 1/3.
PART 2: Identify the y-intercept of the graphed line
The y-intercept of a line is the point where the line crosses the y-axis. In this problem, the line crosses the y-axis at y = 1.
PART 3: Identify the slope of the line given by the equation
The given equation is written in the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept. The slope of the line as shown by the equation is 1/2.
PART 4: Identify the y-intercept of the line given by the equation
As previously stated, the equation is written is the slope-intercept form, so to find the y-intercept in the equation, all we need to do is find the value for b. In this case, b = -1.
Hope this helps!
