Sa t-distribution appropriate? a sample with size has and . the dotplot for this sample is given below. a dotplot ranging from 5 to 11 with dots plotted as follows: 1 dot above 5, 2 dots above 6, 3 dots above 7, 3 dots above 8, 2 dots above 9, and 1 dot above 11. indicate whether or not it is appropriate to use the t-distribution.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

i think the answer is d im not sure

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
