Answer: b
Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is

.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize

.
Answer: 3/10
Step-by-step explanation: by adding the number of coins up you get 10 coins, then minus how many pennies and nickels there are then it comes out with a proper fraction, no simlifying needed :)
Answer:
(2,√21)
Step-by-step explanation:
The circle centered at the origin has equation:

Any point that satisfies this equation lie on this circle.
When x=2, we substitute and solve for y.

Take square root to get:

Therefore (2,-√21) and (2,√21) are on this circle.
From the options, (2,√21) is the correct answer
The patio is 22 feet long.
The act of measuring is the practice of comparing a physical quantity with a recognized standard quantity of a like kind. A base unit, sometimes called a fundamental unit, is a unit used to quantify a base amount. A base quantity is a physical quantity that is part of a traditionally selected subset of physical quantities but cannot be stated in terms of the other physical values in the subset.
Given the scale used is 1cm which represents 5.5 feet.
measure of patio on scale drawing is 4cm.
then it's length is 5.5 × 4 = 22 feet
These measurements pertain to the following: length, mass, time, electric current, temperature, amount of a substance, and luminance. Here are the seven base units' definitions: Distance: meters (m) Metric length is measured in meters.
hence we get the value of the length of the patio as 22 feet.

They answer is they ate 6 kilos! of the 8 kilos because you have to reduce 6/8 to 3/4 and 3/4 of 8 is 6.
