Answer:
340 ft²
Step-by-step explanation:
From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).
First, find the area of the square.
Area of a square = width x length = 10 x 10 = 100 ft²
All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.
Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²
So the total area of all 4 triangles = 4 x 60 = 240 ft²
Therefore the total surface area = 100 + 240 = 340 ft²
Answer:
find where they intersect on the graph or find each line's individual equation and set them equivalent to eachother. x=2

Answer:
1728
Step-by-step explanation: L(length) H(height) W(width)
volume = l x w x h
perimeter= L + W + L + W
perimeter = 12 + 12 + 12 + 12
volume = 12 x 12 x 12 because it' s a cube, and all sides are equal
= 1728
(i don't know if it's right though...)
Answer:
It appears that there ▼ is is not sufficient evidence to conclude that pregnant women can correctly predict the gender of their baby.
Step-by-step explanation:
The results occur by chance.
There's not enough evidence to show that the pregnant women can predict the gender of the babies. 0.327 probability of getting such sample results by chance means 1-0.325 = 0.675 women are unable to predict the gender.
This 0.675 tells us that more than 67 % of the women are unable to predict the gender.
The other option is incorrect .
The probability shows that the sample results ▼ could not have easily occurred by chance.
The probability does not show how the sample results are affected by chance. There' s no increase in the number of trials , there's no evidence of how they guessed.
