Answer:

Amount of gift wrap required is 1090 cm².

Step-by-step explanation:

We are given the dimensions of the rectangular box as,

Length = 20 cm, Width = 7 cm and Height = 15 cm.

Since, we will cover the outside of the box. We have to find the surface area of the box to know the amount of gift wrap required.

As, Surface area of a rectangular prism = 2(l×w+h×l+h×w)

i.e. Area of the rectangular box = 2(20×7+15×20+15×7)

i.e. Area of the rectangular box = 2(140+300+105)

i.e. Area of the rectangular box = 2 × 545

i.e. Area of the rectangular box = 1090 cm²

Thus, the amount of gift wrap required is 1090 cm².

Lemur [1.5K]

Answer:

Option (C).

Step-by-step explanation:

Graphed function is,

f(x) = x² - 2x - 3

     = x² - 2x + 1 - 1 - 3

     = (x² - 2x + 1) - 4

     = (x - 1)² - 4

f(-2x) = (-2x)² - 2(-2x) - 3

        = 4x² + 4x - 3

        = 4(x² + x) - 3

        = 4[x² + 2(0.5)x + (0.5)²- (0.5)²] -3

        = 4(x + 0.5)² - 1 - 3

        = 4(x + 0.5)² - 4

        = 4[(x - 1) + 1.5]² - 4

Therefore, parent function 'f' will be a horizontal shrink by 4 units and  shifted 1.5 units to the left.

Option (C) will be the answer.

The sample was 10 numbers.

4 of the numbers are less than 301.

So 4 out of 10 would be defective.

4/10 = 0.4 x 100 = 40%

He would expect 40% to be defective.
