A quality-control inspector rejects any shipment of printed circuit boards whenever 3 or more defectives are found in a sample of 50 boards tested. Find the (1) expected number defective and (2) the probability of rejecting the shipment when the proportion of defectives in the entire shipment is

(a) Proportion of Defectives=0.01

Expected Number Defective=

Probability of Rejecting the Shipment=

(b) Proportion of Defectives=0.05

Expected Number Defective=
Probability of Rejecting the Shipment=

(c) Proportion of Defectives=0.1

Expected Number Defective=
Probability of Rejecting the Shipment=

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
