Answer:
<em>A = 144 cm^2</em>
Step-by-step explanation:
a.
The 3D shape shown in the image is a prism, known because it has two parallel faces called bases (the front and back triangles) and the other faces being parallelograms.
b.
To compute the total surface area, we must add the area of the five faces of the shape.
For the bases:
For the upper face
Where z is the hypotenuse of the triangle and w is the depth of the prism.
For the face-down surface
For the right face
The total area is
c.
Answer:
x + 2
--------
49
Step-by-step explanation:
that's the answer
It depends on what the level of significance (alpha) is.
Since alpha is not stated, I'll assume that alpha = 0.05 by default.
Because the p-value is smaller than alpha, we reject the null hypothesis.
Therefore, we conclude that the alternative hypothesis is correct and the proportion of heads is greater than 0.5
Answer: point b
Step-by-step explanation:
eatch mark on the line is 0.1, b is right behind the 8.6 mark in the middle making it 8.65
