Answer:
4(6a + 5)
Step-by-step explanation:
24a + 20
the greatest common factor of both terms is 4
4(6a + 5)
No because 8 is to 5 and 10 is to 4, they aren’t connected. Or you can do 8/10= .8 and 5/4= 1.25, they are not the same
Answer: D
Step-by-step explanation:
I substituted in the value of x (2) to see if it gave me the value of y (1) because that’s the point it gave on g(x).
The only equation that worked was D.
1/2*2=1 then 1^2=1
-5 =

- 2
equals x = -4.
First, simplify

to

. / Your problem should look like: -5 =

- 2.
Second, multiply both sides by 4. / Your problem should look like: -20 = 3x -8.
Third, add 8 to both sides. / Your problem should look like: -20 + 8 = 3x.
Fourth, simplify -20 + 8 to -12. / Your problem should look like: -12 = 3x.
Fifth, divide both sides by 3. / Your problem should look like:

= x.
Sixth, simplify

to 4. / Your problem should look like: -4 = x.
Seventh, switch sides. / Your problem should look like: x = -4, which is your answer.
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.
