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.
Dolls = d
trains = t
8d + 10t = 150
I believe we can express it like that.
For Mia's calculations, she should use y first because y signifies 22, while x indicates 4 dollars earned weekly.
B refers to the base of the triangle,
and a signifies the length of the two identical sides.
The measurement labeled as 'a' is larger than 'b' since those equal sides are longer than the base. Given "one of the longer sides measures 6.3 cm," we assign a = 6.3.
Substitute 6.3 for each 'a' in the equation and solve for b:
2a + b = 15.7
2(6.3) + b = 15.7
12.6 + b = 15.7
b = 15.7 - 12.6 (applying subtraction property of equality)
b = 3.1
Answer:
The sequence decreases by 5
thus the subsequent numbers are
