Answer:
A. Increase by 2
Step-by-step explanation:
Given that a fitted multiple regression equation is
This is a multiple regression line with dependent variable y and independent variables x1, x2, x3 and x4
The coefficients of independent variables represent the slope.
In other words the coefficients represent the rate of change of y when xi is changed by 1 unit.
Given that x3 and x4 remain unchanged and x1 increases by 2 and x2 by 2 units
Since slope of x1 is 5, we find for one unit change in x1 we can have 5 units change in y
i.e. for 2 units change in x1, we expect 10 units change in Y
Similarly for 2 units change in x2, we expect -2(4) units change in Y
Put together we have
change in y
Since positive 2, there is an increase by 2
A. Increase by 2
To answer the problem just add the frequencies that
correspond to email counts that are 19 or fewer. So you're adding the counts
that correspond to 0-9 and 10-19. So the frequency of 0-9 is 4 and the
frequency of 10 -19 is 7. So 4 + 7 = 11
Angle 1 is also 54. 2 and 4 are verticals. 4 is 126
These are all parts of circles.
A radius is the distance from the center of a circle to the edge.
A chord is a line segment from 2 different places on a circle.
A tangent is a line that touches the edge of a circle in only 1 place.
Inscribed angles are inside a circle and circumscribed angles are on the outside of a circle.
Answer:
The Area of the bicycle wheel=380.182 square inch
Step-by-step explanation:
The formula for calculating the area of a wheel is given by;
A=(πd²)/4
A=Area of the wheel to be calculated
Where π (pie)=3.142,
The wheel size is usually denoted by its diameter (d)
d=diameter of the wheel=22 inches
with the values of π and d given, we can plug them in the formula for calculating Area to determine the area of the bicycle wheel
Substituting the values for π and d in the formula;
A=(πd²)/4=(3.142×22²)/4=380.182 in²
The Area of the bicycle wheel=380.182 in²
