Smythe Co. makes furniture. The following data are taken from its production plans for the year. Direct labor costs $ 5,870,000

Elenna [48]

Answer:

$2.80 per chair

$2.25 per table

Explanation:

If cost is assigned at a rate based on direct labor hours, the total disposal cost for chairs and tables is, respectively:

$D_c=\frac{254,000}{16,400+254,000}*\$630,000=\$591,789.94\\D_t=\frac{16,400}{16,400+254,000}*\$630,000=\$38,210.06\\$

The respective disposal cost per unit is:

$C = \frac{\$591,789.94}{211,000}=\$2.80/chair\\ T=\frac{\$38,210.06}{17,000}=\$2.25/ table$

Langston will pay $575 to three different credit cards: Expert Card, Passport, and US Speedy. She will pay three times as much t

Gre4nikov [31]

Answer:

$75

Explanation:

Let, the payment made towards US Speedy credit card be 'U'

Therefore,

According to the question:

Payment made towards Express credit card, E = 3U

Total for the two cards = U + E

= U + 3U

= 4U

also,

Payment made towards passport credit card = 15% of 4U

= 0.15 × 4U

= 0.6U

Given: Total payment made = $575

Therefore,

E + U + 0.6 U = $575

3U + U + 0.6U = $575

4.6U = $575

U = $125

Hence,

Payment made towards passport credit card = 0.6U

= 0.6 × $125

= $75

The number of customers who enter a bank is thought to be Poisson distributed with a mean equal to 10 per hour. What are the cha

VLD [36.1K]

Answer:

The probability that 2 or 3 customers will arrive in a 15-minute period is 0.4703

Explanation:

Firstly, we have to determine the segment unit, since the mean is 10 per hour, the segment unit is 1 hour.

The mean(m) = 10

since the period is 15 minutes = 0.25 hour, t= 0.25 hour / 1 hour. Therefore mt= 2*10 = 2.5

The poisson distribution formula P(x) = $\frac{(mt)^{x}e^{-mt} }{x!}$

Therefore the probability that 2 or 3 customers will arrive in a 15-minute period

P(x=2) or P(x=3) = P(x=2) + P(x=3) = $\frac{(2.5)^{2}e^{-2.5} }{2!}+\frac{(2.5)^{3}e^{-2.5} }{3!}$ = 0.2565 + 0.2138 = 0.4703

Therefore P(x=2) or P(x=3) = 0.4703

The probability that 2 or 3 customers will arrive in a 15-minute period is 0.4703
