Option C. 
Step-by-step explanation:
we know that
The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles
so
Answer:
A). Alberto is the only right one because .80 * 5 = 4$
B). Claude will need 1.60$ because .80 * 2 = 1.60$
C). Dora can buy 12.5 pounds because 10$ / .80 is 12.5
D). Using Alberto's because he was the one who was correct

Answer:
Step-by-step explanation:
Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.
r = linear correlation coeff = 0.952
H_0: r =0\\
H_1 :r\neq 0
(Two tailed test)
r difference = 0.952
n=8
Std error = \sqrt{\frac{1-r^2}{n-2} } =0.12496
Test statistic t = 0.952/0.12496 = 7.618
Alpha = 0.05
df = 6
p value = 0.000267
This implies H0 is rejected.
There exists a linear relation between the variables and r cannot be 0
0.952^2 = 0.906=90.6% of variation in weight can be explained by the linear relationship between weight and chest size
36
This is because its a square shape so you would divide 144 by 4 and you get 36
I hope this helps:)
