Answer:
A. 20ft
Step-by-step explanation:
Answer:
D. unfavorable fixed overhead flexible minus budget variance
Step-by-step explanation:
As the cost of the equipment is increasing the fixed efficiency and idle capacity variance would be unfavorable resulting in an unfavorable fixed overhead flexible minus budget variance.
The expenses of the machinery are the fixed indirect costs which result in fixed overhead variances. Since it is related to the working of the machinery it would result in efficiency and idle capacity variances that in turn would give unfavorable fixed overhead of the flexible minus budget variance.
Answer:
The standard deviation of weight for this species of cockroaches is 4.62.
Step-by-step explanation:
Given : A different species of cockroach has weights that are approximately Normally distributed with a mean of 50 grams. After measuring the weights of many of these cockroaches, a lab assistant reports that 14% of the cockroaches weigh more than 55 grams.
To find : What is the approximate standard deviation of weight for this species of cockroaches?
Solution :
We have given,
Mean 
The sample mean x=55
A lab assistant reports that 14% of the cockroaches weigh more than 55 grams.
i.e. P(X>55)=14%=0.14
The total probability needs to sum up to 1,



The z-score value of 0.86 using z-score table is z=1.08.
Applying z-score formula,

Where,
is standard deviation
Substitute the values,





The standard deviation of weight for this species of cockroaches is 4.62.
Answer:
C is the correct answer
Step-by-step explanation:
Answer:
$11.25
Step-by-step explanation:
price = $30/lb
16 oz = 1 lb
1 portion = 6 oz = 6/16 lb = 3/8 lb
$30/lb * 3/8 lb = $11.25
