Answer:
controlled experiment
Step-by-step explanation:
Controlled experiment is a type of experiment in which except for only one variable, everything is kept constant.
The common type of the controlled experiment compares the control group against the experimental group. All the variables are identical between two groups except factor which is being tested.
Big advantage of the controlled experiment is that one can eliminate much of uncertainty about the results.
Answer:
The resultant expression would be 22 - 12x
Step-by-step explanation:
Let x be the unknown number,
Six plus four times a number = 6 + 4x
Four times four minus four times the number number = 4(4 - 4x)
Thus, Six plus four times the number plus four times four minus four times the number number = 6 + 4x + 4(4 - 4x)
Using distributive property,
6 + 4x + 16 - 16x
Combining like terms,
22 - 12x
See the attached picture. You'll find a tree with four branches at level 1 (each of the four sectors of the spinner). Each of these branches is divided in four sub-branches: the possible results of tossing two coins (HH, HT, TH, TT).
So, there are 16 possible outcomes (numbered below each leaf).
If you want to roll an odd number, you have to take branch 1 or 3 at first level.
Then, for each of those, you have to toss exactly one head, so you have to take HT or TH.
The good outcomes are thus 2, 3, 10 and 11, leading to a probability of 4/16=1/4=25%.
Answer:
point-slope form:
y - 10 = -4(x - -2)
y - 10 = -4(x + 2)
---
slope-intercept form:
y - 10 = -4x - 8
y = -4x - 8 + 10
y = -4x + 2
Step-by-step explanation:
You didn't provide the "given point", but I assume you're capable of plugging it in.
