Answer:
11a-16b-26
Step-by-step explanation:
Distribute 3 into first equation.
15a-12b-18.
Distribute -2 into second equation.
-4a-4b-8.
Rewrite as one equation 15a-12b-18-4a-4b-8.
Combine like terms 11a-16b-26
Means-to-MAD ratio is something that wouldn't be hard to find out, but I've certainly <em />never even heard of it.
The
mean (<span>µ) </span>of a set of data points is found by adding them up and dividing by the number of data points.
For our first set:
For our second set:
The
mean absolute deviation is when you find the distance of each data point from the mean and then find the mean <em>of those distances.</em>
For our first set:
<em>
</em>For our second set:
<em>
</em>It wouldn't be hard to find the ratio between these for each set as the question asks...don't forget to put our ratio in simplest form!
For the first set:
<em>
</em>For the second set:
<em>(In a fraction, we would just put this as 3 because the ÷1 is redundant...however, because this is ratio, we have to keep it in)</em><em>

She need 12/8 or 1 4/8 rice and 16/8 of water or 2 wholes.
Answer:
Yes
Step-by-step explanation:
Since P(A)=0.7 and P(A and B)=0.28, then P(B) must be 0.4 because 0.7*0.4=0.28.
Since P(A and B) is a combined probability, P(A) and P(B) are independent.
