Answer: one-half the width of a confidence interval
Step-by-step explanation:
Answer:
x = - 7 or x = 10
Step-by-step explanation:
The absolute value always returns a positive value, but the expression inside the bars can be positive or negative.
Given
| 2x - 3 | = 17, then
2x - 3 = 17 ( add 3 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
OR
- (2x - 3) = 17 ← distribute left side by - 1
- 2x + 3 = 17 ( subtract 3 from both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
As a check, substitute these values into the left side of the equation and if equal to the right side then they are the solutions
x = - 7 → | - 14 - 3 | = | - 17 | = 17 ← True
x = 10 → | 20 - 3 | = | 17 | = 17 ← True
Hence solutions are x = - 7 or x = 10
Answer:
what
Step-by-step explanation:
Since you can only perform addition and subtraction on variables that have the same variable following them, the correct answer is B. 3 - 2i.
Here's why:
1 + 2 + (3i - 5i) =
3 - 2i
Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35 Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)
