-18 = -6n - 6 + 2n Solve for n. ​
vodomira [7]

Answer:

n = 3

Step-by-step explanation:

-18 = -6n - 6 + 2n

-18 = -6n +2n -6 (Combine like terms)

-18= -4n -6

-18+6= -4n -6+6 (Addition Property of Equality)

-12 = -4n

-12/-4 = -4n/-4 (Division Property of Equality)

3=n

The value of 'n' is 3.

Tju [1.3M]

Answer:

0.98 also 98%

Step-by-step explanation:

In this question we have the Lower limit to be 0.16

We have the Upper limit to be 0.24

Such that (0.16+0.24)/2 = 0.40/2 = 0.20

Standard deviation= √(0.2x0.8/545) this gives 0.017134

Next we get margin of error

Margin of error = 0.24-0.20 = 0.04

Z multiplied by sd =0.04

Such that

Z = 0.04/0.017134 =2.33

On this z score, the Corresponding level of confidence is 0.98

Which is 98%

Lucas wants to use the box with the greatest volume
stiks02 [169]

*see attachment for the possible choice answers showing the boxes and dimensions

Answer:

Box D = 27 ft³

Step-by-step explanation:

To find out which has the greatest volume, we need to calculate the volume of each box given in the option using the formula of the volume of a rectangular prism = w × h × l.

Where w = width; h = height; and l = length.

Thus, the volume for the boxes are as follows:

=>Box A:

V = w × h × l

V = 3 × 1 × 5

V = 15 ft³

=>Box B:

V = w × h × l

V = 2 × 3 × 4

V = 24 ft³

=>Box C:

V = w × h × l

V = 1 × 2 × 7

V = 14 ft³

=>Box D:

V = w × h × l

V = 3 × 3× 3

V = 27 ft³

The shipping box with the largest volume is box D with a volume of 27 ft³
