Rewrite the expression 14m - (5+8m) without parentheses
2 answers:
Answer:
Step-by-step explanation:
The question above is answered below.
Rewriting the expression above without parentheses is done by simply removing the parentheses using the negative sign. Note that the signs of the constant (5) and term (8m) in the expression are positive (+). Thus, using the negative sign to remove the parentheses will be done using the arithmetic signs rule: - × + = -, that is, minus times plus equals minus; such that - × +5 = -5 and - × +8m = -8m. Therefore,
In case the expression is to be evaluated, the result will be:
14m - 5 - 8m
Rearrange the terms
14m - 8m - 5
6m - 5

Answer:
Therefore the experimental probability that she will roll an even number is
C ) 0.5
Step-by-step explanation:
Let S be the sample space for the given experiment that to Roll six sided number Cube
∴ S ≡ { 1, 2, 3, 4, 5, 6}
∴ n(S) = 6
Let 'A' be the event of experiment that she will roll an even number
∴ A ≡ { 2, 4, 6 }
∴ n(A) = 3
To Find:
P(A) = ?
Solution:
We know that for any experiment probability is given by
Substituting the values we get
Therefore the experimental probability that she will roll an even number is
C ) 0.5
