You would find the probability of getting an answer less than 10 by counting all of the possible outcomes, or numbers that are less than 10 and compare them to the total number of possible outcomes, or the total number of numbers. You would write the ratio of predicted outcomes to total possibilities.

The answer would be 4/9.

Given:

The figure of a trapezium.

To find:

The measures of missing angle m\angle K, m\angle M.

Solution:

In the given figure JK\parallel ML.

If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.

m\angle J+m\angle M=180^\circ         (Supplementary angles)

87^\circ+m\angle M=180^\circ

m\angle M=180^\circ-87^\circ

m\angle M=93^\circ

Similarly,

m\angle L+m\angle K=180^\circ         (Supplementary angles)

51^\circ+m\angle K=180^\circ

m\angle K=180^\circ-51^\circ

m\angle K=129^\circ

Therefore, m\angle M=93^\circ and m\angle K=129^\circ.

Ricky has 3/4 of a bag of Skittles. He wants to split the rest between between his 5 friends. What fraction of the bag will each
Wittaler [7]

Answer:

  • 3/20, with the assumptions below.

Explanation:

The question seems incomplete.

In order to show you the procedure, I make some assumptions.

Assuming that Ricky wants to split the full content of the 3/4 of a bag between his 5 friends, to find what fraction of the bag will each friend receive you must divide 3/4 by 5.

The operation is:

        \dfrac{3}{4}\div 5

Convert the whole number 5 into fraction using 1 as denominator:

       \dfrac{3}{4}\div \dfrac{5}{1}

Transform the division into multiplication changing the divisor into its reciprocal:

       \dfrac{3}{4}\times \dfrac{1}{5}

Multiply numerator with numerator and denominator with denominator:

       \dfrac{3\times 1}{4\times 5}=\dfrac{3}{20}\leftarrow answer
