We know that the number of workers doubles every week.
This implies that the number of workers of the previous week is exactly half of the current one's.
So, it took 11 weeks for the factory to be at half capacity.
The x coordinate of Z is -4. The y coordinate of Z is -2. I
Answer:
0.149
Step-by-step explanation:
Given that Jason wants to perform a two-tailed test for equality between two independent sample proportions
Each sample has at least 10 "successes" and 10 "failures."
Jason's test statistic is -1.44
Since here proportions are tested Z test might have been used.
Z statistic = -1.44
We can get p value for this Z statistic
p value=0.149
p value for two tailed is 0.149
Comparing this with t statistic we can decide whether to accept or reject null hypothesis.
Answer:
280
Step-by-step explanation:
For example, if Justin Upton gets 155 hits in a season and has 554 at bats, his batting average would be 155/554, or .280. The batting average is usually represented not as a percentage (i.e. 28.0%), but instead as a decimal number with three places after the decimal. A batting average of 1.000 means that the player gets a hit every time he comes to bat, and an average of .000 means the player has no hits.
It should also be noted that not every time a batter comes to the plate counts as an at bat. Plate appearances that do not count as at bats include walks, hit-by-pitches, sacrifices, etc.
Answer:
Part 1) Option B. The independent variable is time (t), in minutes, and the dependent variable is rental cost (r), in dollars. The linear function that models this situation is r equals to r=0.55x+8
Part 2) 30 minutes
Step-by-step explanation:
Part 1)
Let
r ------> the rental cost (dependent variable)
t -----> the time in minutes (independent variable)
The linear equation that represent this problem is equal to
r=(5.50/10)t+8
r=0.55t+8
Part 2) How many minutes can be rented for $25. (Round to the nearest minute as needed.)
we have
r=0.55t+8
For r=$25
substitute and solve for t
25=0.55t+8
0.55t=25-8
0.55t=17
t=30.9 minutes
Round down
t=30 minutes
Note If you round up to 31 minutes the rental cost exceed $25
