Step-by-step explanation: hi
Answer:
2
Step-by-step explanation:
<u>Since it is AP, the common difference is same for any term:</u>
- (4x - 2) - (x + 1) = (6x - 3) - (4x - 2)
- 3x - 3 = 2x -1
- 3x - 2x = 3 - 1
- x= 2
<u>The first 3 terms are:</u>
<u>Since the last term is 18, it means this AP has 6 terms:</u>
<u>Answer: </u>as we need to find the value of x only, it is = 2
Answer:
it is -x^3 + 7x^2 -2x if you meant subtract 2x^3 - 4x^2 But if you meant subtract. 2x^3 - 4x +2 then the answer is -x^3 +3x^2 +2x -2
Step-by-step explanation:
x (x + 4) = 5
x² + 4x = 5
x²+ x + (-5) = 0
(x+3)²+(t+3)²=9
x² + 6x + 9 + t² + 6t + 9 = 9
x² + t² + 6x + 6t + 18 + (-9) = 0
x² + t² + 6x + 6t + 9 = 0
x² + t² + 6(x + t) + 9 = 0
3/x + 4/2x = x - 1
6/2x + 4/2x = x - 1
10/2x = x - 1
10 = (x - 1) 2x
10 = 2x² - 2x
0 = 2x² + (-2x) + (-10)
Answer:
a. The population of interest is:
xi. All workers in the U.S. who have participated in the job-sharing program
b. The variable that is being measured is:
viii. The percentage of the 1035 major firms surveyed which offer job-sharing to their employees
c. The sample selected is:
vi. The 1,035 firms surveyed
d. The parameter is:
v. Proportion of employees who are working mothers
e. The statistic is:
ix. 25% (stated as 23%)
Step-by-step explanation:
The parameter of a population is a fixed value calculated from every individual in the population. It is different from a statistic, which is computed from a sample of the population. The statistic is meant to approximate a population parameter.
