it would be 6 be cause 14 -8 is 6
Answer:
16
Step-by-step explanation:
x^2-8x+k is a quadratic expression of the form ax^2 + bx + c. Here a = 1, b = -8 and c = k. Focus on x^2-8x and complete the square as follows: Take half of the coefficient of x (that is, take half of -8) and square the result:
(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4): (x -4)^2.
Thus, k = 16 turns x^2-8x+k into a perfect square.
There isn't a graph so i cant really answer
B) for each participant in the study, the difference between his/her GPA and the mean GPA
C) for each participant in the study, the model (i.e. the mean) for GPA
D) the GPA of each participant in the study
Answer:
B) For each participant in the study, the difference between his/her GPA and the mean GPA.
Step-by-step explanation:
Residuals in a regression model represent the differences between the observed values (in this case, student GPAs) and the predicted values (the mean GPA predicted by the model). So, option B is the correct description of what you will see when you print the residuals.
Answer:
8x +12
Step-by-step explanation:
The outside factor is applied to each term inside parentheses:
4(2x +3) = 4(2x) +4(3) = 8x +12
To simplify this expression, we should use the Distributive Property.
It states that
a(b+c)=ab+ac
Let's use it:
4(2x+3)
8x+12
That's the answer.
13 cm the height
Use 3.14 or the calculator value for pi and provide an answer accurate
to the nearest tenth.
The volume of a cylinder is calculated using the following formula:
```
Volume = π * radius^2 * height
```
π (pi) is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is approximately equal to 3.14.
In this case, the radius of the cylinder is 12 cm and the height of the cylinder is 13 cm. Substituting these values into the formula, we get:
```
Volume = 3.14 * 12^2 * 13
```
```
Volume = 5881.1 cubic centimeters
```
**Answer:**
The volume of the cylinder is **5881.1 cubic centimeters**.
