Answer:

38/195 or 0.1949

Step-by-step explanation:

The data of the distribution of hair colors of people in the lecture in question is provided bellow.

\begin{array}{cccccc}Blonde&Red&Brown&Black&Gray&Total\\29&30&38&49&49&195\end{array}

The probability that the next person who leaves the lecture will have brown hair is determined as the number of brown-haired people divided by the number of people in class.

P(brown) = \frac{38}{195}=0.1949

The probability is 38/195 or 0.1949.

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.
