Answer:
1/2
Step-by-step explanation:
the dilation factor should be 1/2
- if u count the dots on the sides of the preimage there are 2 dots that's the length
- if u count the dots on the real image it's 4
- therefore 2/4 to it's lowest term is 1/2
- so 1/2 is the scale factor
Answer:
(a) 27 extension lines
(b) 0.9000
(c) 30.0000
Step-by-step explanation:
Number of representatives=2, number of extension lines=2, average calls each representative can accommodate per hour = 15 calls, arrival rate per hour = 30 calls
(a) 90% of the arrival rate = 0.09 × 30 = 27 calls
To handle 27 calls immediately, 27 extension lines should be used
(b) Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 27, number of total outcomes = 30
Probability (call will receive busy signal) = 27/30 = 0.9000
(c) For one extension line, numbers of calls to receive busy signal = 30 - 15 = 15.0000 calls
Number of calls to receive busy signal for the current telephone system with two extension lines = 2 × 15.0000 = 30.000 calls
Answer:
20
Step-by-step explanation:
One angle of a nonagon has an angle of 140 degrees, so
7x = 140.
Divide 140 by 7 to find the value of x.
140 ÷ 7 = 20
