Step-by-step explanation:
B. 6 -4 0 3 1
There is no x^2 term so we use zero instead
Answer:
a) The number of correct answers
b) Discrete
c) Ratio
Step-by-step explanation:
We are given the following in the question:
Experiment:
Evaluate the effectiveness of different study strategies. All students were then given a test on the passage material and the researchers recorded the number of correct answers.
a) The dependent Variable
The number of correct answers given is the dependent variable because it depends on the number of times the passage is read.
b) Nature of dependent variable.
- It is a discrete variable.
- Since, the number of questions will always be expressed in whole numbers and cannot be expressed as decimals.
- They are always counted and not measured.
c) Scale of measurement
- Ratio is used to measure the dependent variable because true zero for the number of correct questions answered exist.
- If the measure is zero that means truly no questions were answered correctly.

Hope this helps! Please consider marking me the Brainliest, it’s not necessary, but very much appreciated. Have a great day!
Answer:
inequality form: w<-1
interval notation: (-1)
if this is not what your looking for then this might help
53w+13<55w+16
get w to one side
subtract 53w from both sides
13<3w+16
get 3w by itself
subtract 16 from both sides
-3<3w
divided both side by 3 to solve for w
-1<w
or w>-1
i hope this helped
and if it helped plzzzz mark as brainlest im trying to level up thanks
