Hello from MrBillDoesMath!
Answer:
32 ft^2
Discussion:
You solved it yourself. The area of a parallelogram of base "b" and height (altitude) "h" is b*h. In this case
Area = 8 * 4 = 32 ft^2
Thank you,

Answer:
Cynthia = 12 guavas
Bessy = 36 guavas
Aicel = 72 guavas
Step-by-step explanation:
Total guavas = 120
Let
Cynthia = x
Bessy = 3x
Aicel = 2(3x)
= 6x
x + 3x + 6x = 120
10x = 120
x = 120/10
x = 12
Cynthia = x
= 12 guavas
Bessy = 3x
= 3(12)
= 36 guavas
Aicel = 6x
= 6 × 12
= 72 guavas
Total = 74 + 36 + 12
= 120 guavas
Assuming you meant 2+3(67x34)=y
67x34=2278
2+3(2278)=y
5(2278) or 5x2278=y
y=11390
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844
