Hello! :)

=8x + (−3) (2x) + (−3) (5) + x + 4 Distribute

=8x + −6x + −15 + x + 4

=8x + − 6x + − 15 + x + 4 Combine like terms

=(8x + − 6x + x) + (−15 + 4)

Box of 24 chocolate contains 6 cream-filled. What is the probability of randomly selecting a cream filled
kifflom [539]

The probability of randomly selecting a cream filled

Chocolate is 1/4

  • Probability is the likelihood of an event will occur
  • Probability of an event is find out by divide the number of favorable outcomes by the total number of possible outcomes.
  • The simplest example is flipping of a coin.
  • There are only two possible outcomes when you flip a coin. It wiil be either heads or tails.
  • Total probability is always lie between 0 and 1

Let E be the event of selecting cream filled chocolate.

Number of favourable outcome = 6

Total number of possible outcome = 24

Probability if selecting a cream filled chocolate = 6/24

= 1 / 4

Hence, the probability of randomly selecting a cream filled chocolate is 1/4

Determine the​ value(s) of h such that the matrix is the augmented matrix of a consistent linear system. [Start 2 By 3 Matrix 1s
Leni [432]

Answer: h = 9

Step-by-step explanation: A system of linear equations is consistent when it has at least one solution.

The matrix given is:

\left[\begin{array}{ccc}-15&21&h\\5&-7&-3\end{array}\right]

Transform this matrix in a row-echelon form:

\left[\begin{array}{ccc}-15&21&h\\5&-7&-3\end{array}\right]   R_{2} = 3R_{2}+R_{1} \left[\begin{array}{ccc}-15&21&h\\0&0&-9+h\end{array}\right]

For this row-echelon form to have solutions:

-9 + h = 0

h = 9

For this system to be consistent: h = 9.
