Answer:
square root of 65
Step-by-step explanation:
all i am going to say is, Pythagorean theorem.
<h3>
Answer: Line B better fits the data</h3>
The smaller sum of the squared residuals, or sum of the squared error, means there is less error when it comes to the line being from all the points. The regression line is closer to the points compared to line A.
Answer:
y= -2/5+5
Step-by-step explanation:
A line must always be written in the form y= and the line given is not. Dividing both sides of the equation by 2 you get y=5/2x-4. This is the equation of the line given.
Perpendicular line have gradients that, when they are multiplied, they are equal to -1
The line given multiplied by the gradient of the line(the one required to find)= - 1. That is 5/2×line= -1.
Dividing both sides of the equation by 5/2 you'll get - 2/5. This is the gradient of the line required.
Using the general formula y=mx+c substitute the gradient into the equation. You'll get something like this y= -2/5x+c.
Substitute the given point into the equation. You'll get something like this 3= -2/5(5)+c.
Calculate the value of c. You'll get c=5.
Substitute the value of c into the original equation. You'll get something like this y= -2/5+5
This is the equation: y= -2/5+5
Answer:
1) A = 27 square units, P = 24 units; 2) 276 mm; 3) A = 8, B = 4, C = 3, D = 5, 108 square feet; 4) 5.
Step-by-step explanation:
1) The sides of the rectangle are 9, 9, 3, and 3.
2) 40 + 40 + 70 + 70 + 28 + 28
3) 32 + 6 + 6 + 24 + 40 = 108
4) 24 + 24 + 20 + 20 + 30 + 30 = 148
740/148 = 5
Answer: $880.45
Step-by-step explanation:
find the cost of tickets
18*11.50= $207
now add the other costs
207+625+25+23.45= $880.45
