Answer:
They can make a right traingle because both sides of the equation are equal these lengths do form a right triangle.
12 * 4 = 48
25 * 4 = 100
48/100 = 0.48, or 48%
12 is 48% of 25

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
Answer:
B) x = 2, y = 1
Step-by-step explanation:
Add the two equations to eliminate the x-variable.
(x +3y) +(-x +6y) = (5) +(4)
9y = 9 . . . . . . .simplify
y = 1 . . . . . . . . divide by 9
You can substitute this value into either equation to find x.
x + 3(1) = 5
x = 2 . . . . . . . . subtract 3
The solution is (x, y) = (2, 1).
The value of x that completes the conditional relative frequency table by column is 0.85
<h3>How to determine the value of x?</h3>
From the complete question, we have the following column elements
0.15 x 1
Express a sum
0.15 + x = 1
Subtract 0.15 from both sides
x = 0.85
Hence, the value of x that completes the conditional relative frequency table by column is 0.85
