Answer:
Step-by-step explanation:
A scatter plot is a two-dimensional data visualization that uses dots to represent the values obtained for two different variables one plotted along the x-axis and the other plotted along the y-axis.
A regression line is a straight line that describes how a response variable y changes as an variable x changes. It is the relation between two variables x and y.
Here,
x = day of a week
y = number of visitors
The given data points are 
Plotting the scatter plot and regression line in Excel, the following is generated which is attached further below.
The regression line is,
Comparing it with the general slope-intercept form 
,
slope = 
The bat fit diagonally across the bottom of the suitcase.
Solution:
Length of the suitcase = 20.5 inches
Width of the suitcase = 29 inches
Using Pythagorean theorem,
Taking square root on both sides, we get
Diagonal of the suitcase = 35.5 inch
Length of the base ball bat = 33 inch
35.5 > 33
Since the diagonal of the suitcase is greater than length of the baseball bat,
The bat fit diagonally across the bottom of the suitcase.
Answer:
AM=AT
Step-by-step explanation:
'
To solve for the values in the variable knowing that the sum of all angles in a triangle add to 180 degrees. Simply use this fact to determine the value of z.
Z = 180 - 115 = 165
Then to solve for x, do the same thing. Add up 51 and 45 and subtract the sum by the 165 degrees.
To solve for y, simply knowing the angle that is present for both 70 and the unknown is 180. Subtract 180 from y.
To actually solve for y add up the value for x and 51 and subtract that amount by 180 degrees.
<u>Answer</u>
y⁻¹ = ∛(4x+8)
<u>Explanation</u>
y=(1/4)x³ - 2.
To find the inverse of this equation, you first make x the subject of the formular.
y=(1/4)x³ - 2
Multiply both sides by 4;
4y = x³ - 8
Add 8 on both sides of the equation;
4y + 8 = x³
x³ = 4y + 8
Apply the cube root on both sides to get the value of x;
x = ∛(4y+8)
The inverse of y=(1/4)x³ - 2 is;
y⁻¹ = ∛(4x+8)
