Ugo [173]

Answer:

Step-by-step explanation:

Set up hypotheses as

$H_0: x bar = 50\\H_a: x bar$

(Left tailed test at 5% level)

Sample mean = 53.4

Sample std dev s = 4.4

Sample std error = 4.4/sqrt 50 = 0.6222

Mean diff = 3.4

Test statistic = Mean diff/std error = 0.5464

(t test only can be used as population sigma is not known)

df = 50-1 =49

p value = 0.2939

Since p>0.05 we accept null hypothesis

OLga [1]

Answer:

a)Total Labor Cost = $600x + $30y.

b) Total variable cost = $3000.

c) Total labor cost last month = $6000.

d) Unit cost of labor per class = $60.

e) Total variable labor cost = $30 * 150 = $4500, Total Labor Cost = $3000 + $4500 = $7500, and Unit cost of labor per class = $7500/150 = $50.

Step-by-step explanation:

a) It is given that the labor cost includes two components: cost of trainers, which is actually their salaries, and cost of a fitness class taught. Fitness trainer costs $600 and one fitness class costs $30. Assuming there are x number of trainers and y number of classes, therefore the model can be expressed as:

Total Labor Cost = Fitness Trainer Cost * number of trainers + Fitness Class Cost * number of classes.

Total Labor Cost = $600x + $30y.

b) The total variable labor cost will be the cost spent on the number of classes. Since number of classes are 100 and the cost of one class is $30, therefore:

Total variable cost = cost of one class * number of classes.

Total variable cost = $30 * 100.

Total variable cost = $3000.

c) Furthermore, last month, x = 5 and y = 100. Plug these values in the total labor cost equation:

Total labor cost last month = $600(5) + $30(100).

Total labor cost last month = $3000 + $3000.

Total labor cost last month = $6000.

d) The total labor cost is $600. Number of classes are 100. Therefore:

Unit cost of labor per class = Total Labor Cost/Number of classes.

Unit cost of labor per class = $6000/100.

Unit cost of labor per class = $60.

e) If the number of classes are increases by 50%, this means that the number of classes will be 150 instead of 100. Therefore:

Total variable labor cost = $30 * 150 = $4500.

Total Labor Cost = $3000 + $4500 = $7500.

Unit cost of labor per class = $7500/150 = $50!!!

Answer:

Step-by-step explanation:

A trapezoid is generally defined as a quadrilateral with <em>exactly one</em> pair of parallel sides. That means a rhombus is not a trapezoid. (No)

A parallelogram has two pairs of parallel sides. (No)

A rectangle may not have equal-length sides, so a rectangle may not be a rhombus. (No)

A rectangle has two pairs of parallel sides, so a rectangle is always a parallelogram. (Yes)

_____

Attached is a relationship diagram to give you an idea of how these quadrilaterals are related.
