The middle 50 percent of data are ages 13-31. Every segment of the plot is 25%, so in this plot the two center big boxes add up to 50%, which span 13-31 years of age.
Width = 5x
length = 7x
Perimeter = 10x + 14x = 24x = 96cm
x = 96/24 = 4cm
width = 5x = 20cm
length = 7x = 28cm
Area = (20cm x 28cm) = 560 cm²
Answer: D. 0.1217
Step-by-step explanation:
Given : The probability that a car will have a flat tire while driving through a certain tunnel :p=0.00005.
n= 14000
Then, the mean number of cars will have a flat tire while driving through a certain tunnel = np

Poisson Distribution Formula : 
For x= 2

Hence, the required probability = 0.1217
Answer:
242.
Step-by-step explanation:
C = 0.03 x 2 − 8 x + 700
When the marginal cost = $522 we have:
522 = 0.03 x 2 − 8 x + 700
0.03x^2 - 8x + 700 - 522 = 0
0.03x^2 - 8x + 178 = 0
Using the quadratic formula:
x = [ -(-8) +/- sqrt( 64 - 4 * 0.03 * 178)] / 0.06
= 8 +/- sqrt42.64 / 0.06
= 242 players.
Answer:
m<DCA = 40
Step-by-step explanation:
m<DAC = 90
m<CDA = 50
m<DCA = 180 - 90 - 50 = 40
