You just add everything

20 + 11 + 9 + 9 + 4 + 4
= 31 + 9 + 9 + 4 + 4
= 40 + 9 + 4 + 4
= 49 + 4 + 4
= 53 + 4
= 57

So therefore ur answer is (A) 57 square yards.

A local charity holds a carnival to raise money. In one activity, participants make a $3 donation for a chance to spin a

g100num [7]

Answer:

The median of the distribution is (first option);

Step-by-step explanation:

The values on the given table are presented as follows;

$\begin{array}{cccccc}Value \ of \ Spin&0&1&2&5&10\\Probability&0.4&0.2&0.2&0.1&0.1\end{array}$

To find the median, we calculate the cumulative probabilities to find the value of the spin art which the cumulative probability is 0.5 as follows;

Cumulative probability, starting from the left, is therefore;

Probability for spin of 0, 0.4 + Probability for spin of 1, 0.2 = 0.6

Therefore, given that the probability of 0.5 occurs within the Value of Spin 1, the median of the probability distribution is 1

A drama club earns $1040 from a production. It sells a total of 64 adult tickets and 132 student tickets. An adult ticket costs

Mashutka [201]

The system of equations would be:

64x+132y = 1040
x = 2y

We multiply the number of adult tickets, 64, by the cost of the adult tickets, x. We multiply the number of student tickets, 132, by the cost of the student tickets, y. Together these add up to $1040.

We know that the cost of an adult ticket is twice as much as a student ticket, so x = 2y.
