Acomputer company wants to start a call center. they designed a simulation using a random number generator to predict the frequency of the types of calls they would receive. solve for the situation.

based on the simulation data, calculate the probability of the first call being a sales call.

28.6%

31.1%

32.8%

36.1%

The correct answer is B. 31.1%. This is the probability of the first call being a sales call.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

There are six types of sales calls with a frequency of 19 calls for the simulation.

There are six types of informational calls with a frequency of 22 calls for the simulation.

There are nine types of technical support call with a frequency of 20 calls for the simulation.

Total of calls for the simulation = 19 + 22 + 20 = 61

2. Let's find the probability of the first call being a sales call.

Probability = Frequency/ Total of calls for the simulation

Probability = 19 / 61

Probability = 31.14% = 31.1% (Rounding to one decimal place)

The correct answer is B. 31.1%.

Probability of the first call being an informational call.

Probability = Frequency/ Total of calls for the simulation

Probability = 22 / 61

Probability = 36.06% = 36.1% (Rounding to one decimal place)

Probability of the first call being a technical support call.

Probability = Frequency/ Total of calls for the simulation

Probability = 20 / 61

Probability = 32.78% = 32.8% (Rounding to one decimal place)

y + 11 = (1/4)(x + 16)

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
