So this problem written out should look like this: 
3(3 x 5)
Firstly, to simplify this we should multiply 3 x 5. That is 15.
3(15)      This is equal to 3 x15, so that is exactly what we must do.
3 x 15 is equal to 45. Tina has 45 CDs in total.
Hope this helps!

In a bolt-manufacturing factory, it is estimated that 6% of the bolts being manufactured will be defective, with a 3% margin of
Lynna [10]

Answer:

D

Step-by-step explanation:

A margin of error provides information on the  percentage points ones results will differ from the real value.

If margin of error is 3% and estimated value is 6%, it means that the confidence interval would be within ±3 of the estimated value.

So, the confidence interval would be between 3% (6% - 3%) and 9% (6% + 3%)

A number is called evil if it has 666 in it. How many 7 digit numbers are evil?
defon

Step-by-step explanation:

There are 5 different positions of 666:

666////

/666///

//666//

///666/

////666

The forward dashes represent any number from 0 to 9.

Case 1: "666////"

Number of ways = 10⁴ = 10,000.

Case 2: The other positions.

Since the 1st forward dash cannot be 0 (leading digit),

Number of ways for each position = 9 * 10³ = 9,000

Number of ways for all 4 positions = 9,000 * 4 = 36,000.

Total evil numbers = 10,000 + 36,000 = 46,000.
