Answer:
(a)
(b)300 Hours
(c)150 Hours
(d)Reduced and halved.
(e)
Step-by-step explanation:
(a) The number of hours worked is inversely proportional to the wage.
This is written as:
(b)If the student earns $8 an hour
w=$8
(c)When the wage per hour =$16
When w=$16
The number of hours reduced and is in fact halved.
(d)
The effect of raising the wage from $w to $2w per hour is that the number of hours required to work is reduced and exactly halved.
(e)The wage per hour is inversely proportional to the number of hours.
In fact,
Answer:
<em>2.5%</em><em> of the snakes are longer than 16.6 in</em>
Step-by-step explanation:
The Z score is,
here,
X = raw score = 16.6
μ = mean = 15
σ = standard deviation = 0.8
So,
Z-score is the measurement of how many standard deviation away the data is from the mean. Hence, the value 16.6 is 2 standard deviations right to the mean.
Approximately 95% of the data falls within two standard deviations of the mean. (between the mean-2 times the standard deviation, and the mean+2 times the standard deviation)
So the 5% of data are left in the remaining space. As we have to find the amount of snakes which are longer than 16.6 in i.e we have to find the area to the right of 16.6.
The remaining 5% of amount is divided in two equal parts.
Therefore, of the snakes are longer than 16.6 in
