Answer:
y = 18 when x = 3
Step-by-step explanation:
y is directly proportional to x^2, meaning:
where a is the proportion between them. We're given the values for both x and y, so plug those in and solve for a:
Now you can use a to solve for y when x is 3:
Answer:
Mean: 58
Median: 58
Step-by-step explanation:
- The mean is a <u>type of </u><u>average</u>. <u>It is the </u><u>sum (total)</u><u> of all the values in a set of data</u>, such as numbers or measurements, divided by the number of values on the list. <u>To find the mean, add up all the values in the set. Then divide the sum by how many values there are.</u>
- <u>The median is the </u><u>middle </u><u>number</u>; <em>found by ordering all data points and picking out the one in the middle</em>
FINDING THE MEAN:
57 + 54 + 59 + 57 + 61 + 58 + 60 = 406
406 ÷ 7 = 58
FINDING THE MEAN:
Arrange the numbers from <u>smallest to greatest:</u>
54, 57, 57, 58, 59, 60, 61
Find the <u>median</u> number:
54, 57, 57, <em><u>58</u></em>, 59, 60, 61
The median is: <u><em>58</em></u>
Answer: I think the answer is 20
The answer should be that you add 15 to both sides to solve for x
