Answer:

Step-by-step explanation:

Find the surface area:

Bottom base: 57 × 27 = 1,539

Top base: 21 × 27 = 567

Rectangular face: 23 × 27 = 621

Trapezoidal face: (21 + 57) ÷ 2 × 15 = 585

1,539 + 567 + 621 + 621 + 585 + 585 = 4,518

The surface area is 4,518 square inches

➷ (12/20) = 0.6

(8/20) = 0.4

The experimental probability of the coin landing heads up is 0.6.

B) The theoretical would be considering it a fair coin.

1/2 = 0.5

The theoretical probability would be 0.5

Trava [24]

Given that Jon said,

"m-1 is always greater than 1-m"

we want to find how true the statement is;

$\begin{gathered} \text{for m = positive integer.} \\ m=5 \\ m-1=5-1=4 \\ 1-m=1-5=-4 \\ So,\text{ } \\ m-1>1-m \\ \text{for m equals positive integer } \end{gathered}$

secondly for negative values of m;

$\begin{gathered} m=-5 \\ m-1=-5-1=-6 \\ 1-m=1-(-5)=1+5=6 \\ So, \\ m-1$

So, the statement "m-1 is always greater than 1-m" is false.

Because 1- m is greater than m-1 when m is a negative integer.

Therefore, I Disagree, because 1- m is greater than m-1 when m is a negative integer
