Answer:
A. -4
Step-by-step explanation:
Slope is rise over run, or y2-y1 / x2-x1.

<u>The slope is A. -4.</u>
Let's see--does that make sense? A slope of four would be pretty steep, and that matches the graph. It also should be negative because the line goes down and to the right, not up and to the right, so -4 makes sense!
Answer:
The mean is 60.17 if round to the nearest hundredth.
Step-by-step explanation:
Add all the numbers together to get 361, then divide by 6 because that is how many numbers were added together.
Answer:
As problem is of regression analysis,thus r^2 will be 24 and sy/x is 4.
Quartic => polynolial degree 4, i.e. the highest exponent of the variable is 4
trinomial=> three terms
leading coefficient = the coefficient in front of the term with the highest exponent.
standard form=> ax^4 + bx^3 + c^2 + dx + e
Solution:
2x^4 + x^3 + 0x^2 + 0x + 30
which is equal to 2x^4 + x^3 + 30: this is a quartic trinomial with leading coefficient 2, written in standard form.
The fraction of the red haired students are boys will be 2 / 5.
<h3>What is a fraction number?</h3>
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The dual bar chart shows the hair colour of boys and girls in a year group.
The total number of the boys and girl will be
Total = 6 + 9
Total = 15
Then the fraction of the red haired students are boys will be
⇒ 6 / 15
⇒ 2 / 5
