3. A weight is suspended from two ropes, which make angles $\theta_1 = 35^\circ$ and $\theta_2 = 155^\circ$, measured from the horizontal. Both support a weight of 450 N in equilibrium. Find the tension in each of the two ropes. Hint: The sum of all the forces in the x and y directions are equal to zero. Solve using simultaneous equations.

The Emerson Division of Golding Company produces small kitchen appliances. The company uses a standard cost system for production costing and control. The standard cost sheet for its most popular product, a toaster, is given below: Direct materials (2.5 lbs. @ $4.00) $10.00 Direct labor (0.7 hrs. @ $10.50) 7.35 Variable overhead (0.7 hr. @ $6.00) 4.20 During the year Emerson experienced the following activity relative to the production of its toasters: a. Production of toasters totaled 50,000 units. b. A total of 130,000 pounds of raw materials was purchased at $3.70 per pound. c. There were 10,000 pounds of raw materials in beginning inventory (carried at $4 per pound). There was no ending inventory. d. The company used 36,500 direct labor hours at a total cost of $392,375. e. Actual variable overhead totaled $210,000. Emerson produces all of its toasters in a single plant. Normal activity (capacity) is 45,000 units per year. Standard overhead rates are computed based on normal activity measured in standard direct labor hours. Required: (a) Compute price and usage variances for materials. (b) Compute the labor rate and labor efficiency variances. (c) Compute the variable overhead spending and efficiency variances.

According to a USPS study, the weight of a randomly selected shipment box is normally distributed with a mean of 21.3 lbs and a standard deviation of 4.7 lbs. Let X be the weight of a randomly selected shipment box and let S be the total weight of a random sample of size 23. 1. Describe the probability distribution of X and state its parameters µ and ?: X ~ Select an answer) (? = ?= ) and find the probability that the weight of a randomly selected shipment box is between 12 and 13 lbs. (Round the answer to 4 decimal places) 2. Use the Central Limit Theorem Select an answer to describe the probability distribution of S and state its parameters µs and ?s: (Round the answers to 1 decimal place) S ~ Select an answer (µs = ?s = ) and find the probability that the total weight of a sample of 23 randomly selected shipment boxes is less than 494 lbs. (Round the answer to 4 decimal places)
