1. Use the figure below to answer the questions.
olasank [31]

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:

\displaystyle A_b=2\cdot \frac{bh}{2}=bh

For the upper face

A_u=z.w

Where z is the hypotenuse of the triangle and w is the depth of the prism.

For the face-down surface

A_d=b.w

For the right face

A_r=h.w

The total area is

A=bh+zw+bw+hw=bh+w(z+b+h)

c.

A=4\times 3+11(5+3+4)=12+132=144

A=144\ cm^2

When spinning a penny, Claire believes the proportion of times the penny lands on heads is higher than 0.5. She spins a penny 50
ss7ja [257]

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
