<span>100 + 30x = 50 + 35x.
-50    -30x    -50   -30x

50 = 5x

10 = x

At ten months they would have paid the same amount so at 11 months, Lisa would pay more than Kelly.</span>

B- 11 months , Kelly would pay $430 and Lisa would pay $435


30 times 11 = 330 + 100= 430 -Kelly

35 times 11=385 + 50= 435

Step-by-step explanation:

Complex numbers on the complex plane are in essense the same, when it comes to midpoints. Applying the midpoint formula, we get the midpoint as  ( 3+2i + 7-3i ) /2 , or (10-i)/2, or 5- i/2

What is the probability of flipping a coin 12 times and getting heads 3 times? Round your answer to the nearest tenth of a perce
attashe74 [19]
<h3>Answer: A) 5.4%</h3>

==================================

Explanation:

We use the binomial probability formula here

P(k) = (n C k)*(p)^k*(1-p)^(n-k)

In this case, there are n = 12 trials and p = 0.5 is the probability of getting heads. The value of k = 3 means we want 3 heads.

So,

P(k) = (n C k)*(p)^k*(1-p)^(n-k)

P(3) = (12 C 3)*(0.5)^3*(1-0.5)^(12-3)

P(3) = 220*(0.5)^3*(1-0.5)^(12-3)

P(3) = 0.0537109375

P(3) = 0.054

P(3) = 5.4%

-----------------

Side note: the n C k refers to the nCr combination formula

_n C _r = \frac{n!}{r!*(n-r)!}

where the exclamation marks mean factorials. You could also use Pascal's Triangle as an alternative for this portion.
