Answer:

55 percent of the surveyed employees preferred to eat lunch at their desk.

Step-by-step explanation:

Here, the total number of surveyed employees  = 40

The number of employees who prefer having lunch at their desk  = 22

Now,\textrm{Percentage of the employees who prefer to do so }  = \frac{\textrm{Number of people who prefer their desk for lunch}}{\textrm{Total employees surveyed}}  \times 100

= \frac{22}{40}  \times 100  =  55

or, Percentage of the employees who prefer to do so = 55%

Hence, 55 percent of the surveyed employees preferred to eat lunch at their desk.

rodikova [14]

Answer: There are 4 average cars in the system.

Step-by-step explanation:

Since we have given that

Arrival rate = λ = 4 cars per hour

Service rate = μ = 5 cars per hour

We need to find the average number of cars in the system.

So, Average number of cars would be

L_q=\dfrac{\lambda^2}{\mu(\mu-\lambda)}\\\\L_q=\dfrac{4^2}{5(5-4)}\\\\L_q=\dfrac{16}{5}\\\\L_q=3.2

So, it becomes,

L=L_q=\dfrac{\lambda}{\mu}\\\\L=3.2+\dfrac{4}{5}\\\\L=3.2+0.8\\\\L=4

Hence, there are 4 average cars in the system.

A store sells tents,sleeping bags,and campstools.A customer buys a tent, 2 sleeping bags, and 3 campstools for 212$.the price of
igor_vitrenko [27]

The cost of each campstools, tent and sleeping bag is $20, $100 and $26

let

tent = 1

sleeping bags = 2

campstools = 3

Total cost = $212

tent = t

sleeping bags = s

campstools = c

If

t = 5c

s = c + 6

Total = t + 2s + 3c

212 = 5c + 2(c + 6) + 3c

212 = 5c + 2c + 12 + 3c

212 = 10c + 12

212 - 12 = 10c

200 = 10c

c = 200/10

c = 20

t = 5c

= 5 × 20

= 100

s = c + 6

= 20 + 6

= 26

Therefore, the cost of each campstools, tent and sleeping bag is $20, $100 and $26

Find the value of x if 9^1/2 • 9^1/2 = x^√81
mario62 [17]

Answer:

(√9)^2x-1/2 = 1/81

3^2x-1/2 = 1/(3)⁴. (as √9 = 3)

3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)

as base are equal exponents are equal

so 3 gets cancelled out

2x-1/2 = -4

(4x-1)/2 = -4

4x-1 = -8

x = -7/4

hope this helps
