To figure out the solution in a problem related to calculate maximum or minimum of something, you've to derive the involved equation, and make it equal to 0, solving the x.
So:
y = -0'296x² + 2'7x
y' = -0'592x + 2'7
0 = <span>-0'592x + 2'7
</span><span>-0'592x = 2'7
</span>x = 4'56
And if we substitute 4'56 on the first equation:
y = -0'296·<span>4'56² + 2'7·4'56
y = 6'16
So the length of the jump is 4'56cm, and the height 6'16cm.</span>
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.
Answer:
the initial height
Step-by-step explanation:
given the height is represented by the function
f(t) = - 16t² + 40t + 3
Then the initial height is when t = 0, that is
f(0) = 0 + 0 + 3 = 3 ← initial height
21, 42, 63, 84, 105, 126, 147
Total numbers in set: 7
Mean (Average) 84
Median (Middle): 84
Mode (Most Common): No mode of this set
Range (Biggest - Smallest): 126
Mean is the average of all data in set.
Median is the value which occurs most frequently in a data set.
Range is the difference between the largest, and smallest data set.
