Step-by-step explanation:
Answer:
He worked 8 hours overtime.
Step-by-step explanation:
A man was paid per hour up to 40 hours = $3.00
He was paid for 40 hours = 40 × 3 = $120
He did overtime, for which he was paid twice of the regular payment = 2(3)
= $6.00
He was paid for his overtime = 168 - 120 = $48.00
His overtime payment per hour = $6.00
He did overtime = 48 ÷ 6 = 8 hours
He worked 8 hours overtime.
Answer: its C
Step-by-step explanation:
It is more affected by extreme values than the arithmetic mean
Explanation
The median is not affected by outliers. In fact, whenever there are outliers, the median is the better measures of center. For instance, housing prices use the median home value because some multi-million dollar mansions positively skew the distribution. These few and large outliers pull on the mean to make it larger than it should be. On the other hand, the median is not affected by this pull.
This is why choice C is a false statement, and it's the final answer.
Choices A, B, and D are true statements. This allows us to rule them out.
given that A and B are parallel, you can conclude that 30 = x - y since they are corresponding angles. Also you can conclude that 5y = 2x since they are alternate interior angles. At this point, there is a solvable system of equations set up
30 = x - y
5y = 2x
Now, you must isolate a variable so let's isolate x from the 1st equation. so u just need to add y to both sides, getting x = 30 + y. Now you plug that into the 2nd equation and solve for y. 5y = 60 + 2y. Subtract 2y from both sides. 3y = 60. Divide by 3, y = 20.
Now with your y value, just plug back into original equation (the 1st one). 30 = x - 20. Solve for x by adding 20. X = 50
second sample indicates that only 15% of the trees are oak. The third sample
indicates that 26% of the trees are oak. The fourth sample indicates that 29% of
the trees are oak. Based on the data, about how many of the 700 trees are oak?
Using proportions, it is found that about 175 trees are oak.
A proportion is a fraction of a total amount.
For the four samples, the proportions are: {0.3, 0.15, 0.26, 0.29}.
Hence, the mean proportion is given by:
M = (0.3 + 0.15 + 0.26 + 0.29)/4 = 0.25
Out of 700 trees:
700 x 0.25 = 175.
About 175 trees are oak.
