55% of 6th grade students voted in the student election. 440 sixth grade students voted in the student election. How many total
Ne4ueva [31]

Answer:

800. Here's why:

Step-by-step explanation:

This indicats that 440 students make up 55% of the 6th grade population. We can write this as

55/440.

We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as

100/x.

55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders

A true-false quiz with 10questions was given to a statistics class. Following is the probability distribution for the score of a
SSSSS [86.1K]

Using the mean <u>formula and it's interpretation</u>, it is found that:

1. The mean is 7.52.

2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.

The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.

Hence, in this problem, according to the <u>distribution given</u>, the mean is:

E(X) = 5(0.06) + 6(0.12) + 7(0.33) + 8(0.29) + 9(0.13) + 10(0.07) = 7.52

The mean is 7.52.

The <em>interpretation </em>is that over many trials, the mean would approach 7.52.
