How much wrapping is needed for a package that is shaped like a cube<br> 16 in. on each edge?
PtichkaEL [24]

Answer:

1536 in^2

Step-by-step explanation:

This is basically asking for the surface area so knowing that is a cube all the sides are equal so one side would be 16(16) which is 256 in ^2.  The knowing that there is 6 sides you would multiply it by 6 which is 256(6)= 1536^2

A particular paper included the accompanying data on the tar level of cigarettes smoked for a sample of male smokers who subsequ
Dafna1 [17]

Answer:

Check the explanation

Step-by-step explanation:

H_0:proportion of male smoker lung deaths is same for the four given tar level categories.

H_1:proportion of male smoker lung deaths is not the same for the four given tar level categories.

Expected frequency=1177/4=294.25

Tar level     Observed Freq.(O)        Expected Freq.(E)         (O-E)^2/E

0-7                         107                                   294.25                120.435

8-14                        375                                  294.25                5.643

15-21                       553                                 294.25                 227.533

>=22                       183                                  294.25                 42.061

Total=                    1177                                  1177                      395.673

Total chi square score=395.673

df=4-1=3

p-value=CHIDIST(395.673,3)<0.001

p-value<0.001,Reject null hypothesis.

There is sufficient evidence that the proportion of male smoker lung deaths is not the same for the four given tar level categories.

Help pleaseee URGENT!!!!!!!show work
sdas [7]

Answer:

look below.

Step-by-step explanation:

When there's a letter, it represents a variable. You need to find the value (number) of this variable. This can be done by trying to isolate (put it by itself) the variable. So now, here is how to do it:

1) -2j + 6 = 2j - 8

-2j - 2j = - 8 - 6

-4j/4 = -14/4

j = 14/4

j = 7/2

2) 4h + 6 = 2h - 8

4h - 2h = - 8 - 6

2h/2 = - 14/2

h = -7

3) 9w + 9 = 3w - 15

9w - 3w = - 15 - 9

6w/6 = -24/6

w = -4

4) 45 = -9(e + 8)

45 = -9e - 72

45 + 72 = -9e

117/-9 = e

e = -13

5) 35 = -7t

35/-7 = t

t = -5

6) 12k + 13 = 8k + 33

12k - 8k = 33 - 13

4k/4 = 20/4

k = 5
