Answer:
0.0016283
Step-by-step explanation:
Given that:
Proportion of defective bulbs, p = 30% = 0.3
Sample size, n = 19 bulbs
Probability that the lot will pass inspection :
P(none of the 19 is defective) Or P(only one of the 19 is defective)
P(none of the 19 is defective) = (1 - p) ^n = (1 - 0.3)^19 ; 0.7^19
0.7^19 = 0.0011398
P(only one of the 19 is defective) :
P(1 defective) * P(18 not defective )
(0.3) * (1 - 0.3)^18
0.3 * 0.7^18
0.3 * 0.001628413597910449 = 0.0004885
Hence,
P(none of the 19 is defective) + P(only one of the 19 is defective)
0.0011398 + 0.0004885) = 0.0016283
Answer: 
Step-by-step explanation:
Let x be the price. 20% (0.20) 7.25% (0.0725)

we are given

Since, we have to find inverse of this function
step-1: we set f(x)=y

step-2: switch x and y

step-3: Solve for y

now, we can use quadratic formula

Yes, the partition gives the two brothers equal shares.
Step-by-step explanation:
Step 1:
Assume the entire field has an area of B. So one brother takes
,
, and
So we need to calculate how much this brother takes in terms of B.
To do this we calculate how much
is.
Step 2:
To add
,
First take the LCM of the denominators 12, 6, and 4
The LCM is 12, we multiply the denominator to get the LCM value, this same value is multiplied to the numerator too.

Step 3:
One brother gets
, so we need to calculate how much the other brother gets.
The other brother's share = 
So both the brothers get equal shares
