To determine the weighted moving average for period 13 using weights of 0.4 and 0.3, you calculate:
P13 = (30.7 x 0.4) + (42.0 x 0.3)
P13 = 12.28 + 12.60
P13 = 24.88.
It amounts to 96. I hope this was helpful.
<span>Let A = a3b + 9a2b2 - 4ab5, and B = a3b - 3a2b2 + ab5. The difference can be expressed as A - B = a3b + 9a2b2 - 4ab5 - (a3b - 3a2b2 + ab5). When the negative sign is in front of the parentheses, all the internal signs change: this leads to: A - B = a3b + 9a2b2 - 4ab5 - a3b + 3a2b2 - ab5 = a3b - a3b + 9a2b2 + 3a2b2 - 4ab5 - ab5 = 12a2b2 - 5ab5. The first term’s degree is 2 + 2 = 4, while the second term’s degree is 1 + 5 = 6. Thus, the correct response is that the difference is a binomial of degree 6.</span>
Answer:
6 * 3/4 = 4.5 = 9/2 = 412
Step-by-step
6 * 3/4 = 6/1 3*4 = 18/4 = 9/2
2 · 2 = 9/2
Both the numerators and denominators are to be multiplied. Retain the resulting fraction with the lowest possible denominator; GCD(18, 4) = 2. In this intermediate calculation, cancelling by the common factor of 2 results in 9
2
.
In summary - six times three quarters equals nine halves.
