0.00592 to 4 decimal places
Leya [2.2K]
0.00592 ≈ 0.0059  to 4 decimal places.

The number after the fourth decimal place is 2, and this is not up to 5, so we round down.

Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 110 cards,
Yakvenalex [24]

Answer:

The answers to the questions are;

(a) P(At least 1 defective)

= 0.9883.

(b) P(At least 1 defective)

= 0.6409.

Step-by-step explanation:

There are 110 cards and 20 defectives.

a) The probability of at least one defective is given by

P(At least 1 defective) = 1 - P(0 defective)

P(0 defective) = 20C0 × (90C0)/(110C20) = 0.0116

1 - 0.0116 = 0.9883

b) For a set of 110 boards that has 5 defective and 105 non-defective

P(At least 1 defective) = 1 - P(0 defective)

P(0 defective) = (20C0)(90C5)/(110C5) = 0.35909

1-0.35909

= 0.6409

A student has a 90, 84, and an 86 on their first 3 tests. What possible scores would the student need
Ugo [173]
The student would have to score 100% on their next test to brung their average up to 90. Here is why;
90+84+86=260
(260+?)/4=90
(260+100)/4=90
360/4=90
This is done to get the mean (or average) of a group of numbers by adding all the numbers and dividing by the amount of numbers you added together. Here it is divided by 4 because of the three tests he has taken and the test he will take.
