A metal Fabricating Company produces 150,000 souvenir tokens each year. In a random sample of 400 tokens, 3 have stamping errors. Predict the total number of coins that will have stamping errors in a year.

1125

150000 divided by 400 equals 375, times 3 equals 1125.

150000 divided by 400 equals 375, times 3 equals 1125.

PLEASE I NEED HELP ASAP! Determine if 9x2 - 42x + 49 can be the area of a square. If so, what would the value of x have to be if the area of the square is 64 square meters? A = s2

Explain your reasoning

9x^2 - 42x + 49 is a perfect square trinomial. It factors to (3x - 7)^2

If the area is 64m^2 set this equal to the factors and solve.

(3x - 7)^2 = 64

Take the square root of both sides.

3x - 7 = + - 8

3x - 7 = 8 3x - 7 = - 8

Add 7 to both sides.

3x = 15 3x = - 1

Divide both sides by 3.

x = 5 x = -1/3

x cannot be -1/3 because it would make the length negative.

The answer is x= 5

If the area is 64m^2 set this equal to the factors and solve.

(3x - 7)^2 = 64

Take the square root of both sides.

3x - 7 = + - 8

3x - 7 = 8 3x - 7 = - 8

Add 7 to both sides.

3x = 15 3x = - 1

Divide both sides by 3.

x = 5 x = -1/3

x cannot be -1/3 because it would make the length negative.

The answer is x= 5
