No, that would be an invalid inference because he actually sampled from only half of the total population not the entire population.
so 12% of the 50% he sampled would be valid, but since he did not use the entire population, the results cannot affect all of them.<span />
The total of the hoodie would be $64 dollars & you will have $16 dollars remaining.
The answer is 520x.
Let x be the price of wallpaper per square feet.
Dimensions of a kitchen are:
width: w = 12 ft
length: l = 14 ft
height: h = 10 ft
If you need to put wallpaper in the room, you will put it only on the walls. There are 4 walls in the kitchen: two walls which dimensions are 12 ft and 10 ft, and two walls which dimensions are 14 ft and 10 ft. Since walls are of rectangular shape, we will use the following formula for the area of walls:
A = 2 * w * h + 2 * l * h
A = 2 * 12 * 10 + 2 * 14 * 10
A = 240 + 280
A = 520 ft²
So, if 1 square foot costs x, 520 square feet will cost 520x
To find the number of ways to do this, first multiply the total number of each kind by the number that can be selected.
5 x 3 = 15
8 x 4 = 32
7 x 4 = 28
Now, add them all together.
15 + 32 + 28 = 75
