The number of ways to arrange the 5 writings in a row is 5! = 5 * 4 * 3 * 2 * 1 = 120 ways.

There is only 1 way to arrange the writings from oldest to newest.

Therefore, the probability is 1/120.

On a number line, the coordinates of j, k, l, m, n are −10.5, −4, −1, 1.5, 4 respectively. find the lengths of the two segments.
nordsb [41]

Answer:

  • JK = 6.5
  • KM = 5.5
  • not congruent

Step-by-step explanation:

JK = K-J = (-4) -(-10.5) = 6.5

KM = M -K = 1.5 -(-4) = 5.5

6.5 ≠ 5.5, so the segments are not congruent.

There is no solution to the equation cscx=0.<br> True or False
Svetradugi [14.3K]

Answer:

True

Step-by-step explanation:

First, we need to recognize that

csc(x)=\frac{1}{sin(x)}

Now, we can try to solve

\frac{1}{sin(x)} =0

Multiply each side by sin(x)

1=0*sin(x)\\\\1=0

As we end up with an answer that cannot be true, we know that there is no solution.

Another method to solve this would be graphing the function y=csc(x)

When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.
