Alright, can someone that is competent in this concept explain to me about residuals? I am studying for a quiz tomorrow. I will mark brainliest if you give me a good and hopefully detailed explanation about residuals.
Answer:
Hey buddy, here is your answer. Hope it helps you.
Step-by-step explanation:
It is the difference between the dependent variable and a predicted value.Each data point has one residual. Residual = Observed value - Predicted value. A residual is a measure of how well a line fits an individual data point.

Olivia buys a pair of jeans that cost 38$ Which means you already got
38 -
She wants to buy shirts that cost 21$ and we dont know how many shirts so it is x so you will multiply
21 times x
and the symbol will be less than or equal too because it cant be greater than bc she only has 150$

Step-by-step explanation:
In order to solve the problem, you first need to figure out how many pages she read on Tuesday. C addresses this by using PEMDAS. You then need to add 5 to that total because that is how many pages she read on Monday. Those steps need to be in parentheses because you are multiplying that total by 2.
Calculate the estimated density of each ball. Use the formula
D = m/V
where D is the density, m is the mass, and V is the volume. Record your calculations in Table A of your Student Guide.
Given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. Record your prediction in Table A.
What is the estimated density of the table tennis ball? Record your answer to the nearest hundredth.
g/cm3
What is the estimated density of the golf ball? Record your answer to the nearest hundreth.
g/cm3
Answer:
Step-by-step explanation:
What is the estimated density of the table tennis ball? Record your answer to the nearest hundredth.
⇒ 0.07 g/cm3
What is the estimated density of the golf ball? Record your answer to the nearest hundreth.
⇒ 1.37 g/cm3
The estimated density of a tennis ball is 0.25 g/cm³.
The estimated density of a golf ball is 0.33 g/cm³.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
To calculate the estimated density of each ball, we need to use the formula D = m/V, where D is the density, m is the mass, and V is the volume.
We can then record the calculations in Table A, along with our predictions about whether each ball will float in water, based on the density of water being 1.0 g/cm³.
For the table tennis ball, we have:
D = m/V = 2 g / 8 cm³ = 0.25 g/cm³.
Based on this density being less than that of water (1.0 g/cm³), we predict that the table tennis ball will float in water.
For the golf ball, we have:
D = m/V = 1 g / 3 cm³ = 0.33 g/cm³
Based on this density being less than that of water (1.0 g/cm³), we also predict that the golf ball will float in water.
We can record our calculations and predictions in Table A as follows:
Ball m (g) V (cm³) Density (g/cm³) Floats in water?
Table tennis 2 8 0.25 Yes
The golf ball 1 3 0.33 Yes

Lin's family has completed 60% of a trip. They have traveled 30 miles. How long is the whole trip?
The number of miles the whole trip is 50 miles.
Given that, Lin's family has completed 60% of a trip.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of miles be x.
so, 60% of x=30
⇒ 60/100 ×x=30
⇒ 0.6x=30
⇒ x=30/0.6
⇒ x=50 miles
Therefore, the number of miles the whole trip is 50 miles.
