Answer:

32.68

Step-by-step explanation:

Now we need the circumference of the circle, with the formula 2 pi r

2 times pi is about 6.28 that times the radius, (1.3) Which is 8.17.

So the circumference of the circle is 8.17, and the height is 4.  

Multiply those together to get the surface area around the can. Not including the top and bottom.

8.17 * 4 = 32.68

The surface area of the label of the can is 32.68

Answer:

First of all, lateral means the sides of the can in this case.

Calculate the surface area of the can, subtract the area of the top and bottom which are two circles, and theres the answer!

Step-by-step explanation:

1. SA= 2πrh+2πr^2

= 2(π)(1.3)(4) + 2(π)(1.3^2)

= 43.29- (π1.3^2)^2

=15.09

Please note that ^(a number) means to the power of (that number). Hope this helps!

The conditional relative frequency table below was generated by column using frequency table data comparing the number of calori
inessss [21]

Answer:

B. There is an association because the value 0.15 is not similar to the value 0.55

Step-by-step explanation:

Based on the above picture, for the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.

The conditions that satisfy whether there exists an association between conditional relative frequencies are:

1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.

2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.

For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45

We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

Step-by-step explanation:

it's C because whenever it says and you're supposed to multiply always remember that :) = (which means area ofc) you're finding the so you multiply 16x8 and the you get your answer (: ignore the 640 you just focus on the 16 and 8 ok? 16x8=128! :))

Ugo [173]
Given:
18 points on her quiz
24 points is equivalent to 100%

18 is to 24 or 18/24
x is to 100% or x/100%

18/24 = x/100%

18 * 100% = 24x
1800% = 24x
1800%/24 = x
75% = x

18/24 = 75%/100%
18 * 100% = 24 * 75%
1800% = 1800%
