Mathematics

First lets simplify the first term and yield (2a)

The second term:
1.   2a * (-1/2) = -a
2.   -a + a = 0

Now we have simplified both terms to: (2a) (0)

Anything multiplied by 0 is 0, so the answer is also 0.

A(2)*(2a(-1/2)+a)
= (2a)*(-1*a+a)
=(2a)*(-a+a)
=(2a)*0
=0

So 0 is the final answer.

Hope this would help :))

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.

Please help . 20 points for right answer

You would add up the percentages first, which would bring everything up to 35%. You would then take the original cost of the item, which is $30 and multiple it by the 35%. 

The equation would look like...

30 x .35 = 

This will give you $10.50, which isn't the final answer.

You would then subtract 10.50 from the $30 that was asked for at the beginning by the retailer. 

Your final answer is $19.50. :) Which isn't a bad deal if I say so myself.

A sweater is on sale for 20% off the regular price. The sale price is $60. What is the regular price of the sweater?
qaws [65]
The answer is B

If the sweater is on sale for 20%, then the sale price will be 80% of the regular price.

Therefore, $60 = 80% of regular price

$60/80 = $0.75 which gives you 1% of the regular price
So $0.75 is 1% of regular price.

$0.75 * 100 = $75 which gives you the regular price as 1% multiplied 100 times = full price

Soooo, full price is b.) $75
