Okay, so 7/20 is 0.35. Why would you multiply it by 5?

1 answer:

8 0

Wow, fairly simple although it seems hard. :D

ou need to get it over 100 for easy change to a decimal.

7/20 is equal to 35/100. 

You multiplied the 20 by 5 to get 100 
You need to multiply the 7 by 5 to get 35 

You get 35/100 

Any number over 1 is itself. 

Divide 100 by 100 to get 1 

Divide 35 by 100 (You can do that right) to get 0.35 

=0.35

Suppose that the handedness of the last fifteen U.S. presidents is as follows:40% were left-handed (L)47% were Democrats (D)If a

lesantik [10]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Probability that they were left handed P(L)= 40%

Probability that they were Democrats P(D)= 47%

So, P(L∩D) = 135 = 0.13

Now, to check whether they are independent or not.

We will find P(L) × P(D) is given by

$P(L)\times P(D)=0.47\times 0.40=0.188$

Since P(L) . P(D) ≠ P(L∩D)

So, they are not independent.

Hence, Option 'c' is correct.

If the cube has a side length of 12 inches, what is the surface area of the cube?

Ne4ueva [31]

The equation for surface area on a cube is 6 * L^2, where L is side length. Essentially, six squares of equal size
12^2=144
6 * 144=864
I hope you found this both helpful and explanatory
