Answer:
$24,240
Step-by-step explanation:
20,000 + 1,060 (5-1)
8t + 1 + (-4t) + (-6) =
8t + 1 - 4t - 6 =
4t - 5 <==
18 tens= 180
20 ones= 20
180+20= 200
200
Answer:
The probability that a radio selected at random will last from 600 to 700 hours is 0.3413
Step-by-step explanation:
The playing life of a Sunshine radio is normally distributed
Mean =
Standard deviation =
We are supposed to find the probability that a radio selected at random will last from 600 to 700 hours i.e.P(600<x<700)
Formula:
At x = 600

Z=0

At x = 700

Z=1


Hence the probability that a radio selected at random will last from 600 to 700 hours is 0.3413
6x^2 + 7x - 5 = (3x + 5)(2x - 1)
Its 2x - 1
