Answer:
<u>The modal temperature last year is 11 (March and November)</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
A year ago Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
9 10 11 14 19 22 27 29 21 18 11 6
2 years ago Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
7 11 10 13 17 23 25 25 20 18 12 9
2. What was the modal temperature last year?
Let's recall the mode of a data set is the number that occurs most frequently in the set. The number that occurs the most in the average temperatures last year is 11 (March and November) and 2 years ago is 25 (July and August)
Answer:
point slope form:
y - 3 = -4/3(x- (-1))
slope intercept form:
y = -4/3x + 13/3
Step-by-step explanation:
So if the points are (7, -4) and (-1,3) then we can use those points to figure out the slope.
y2-y1/x2-x1 is the forumla for the slope
3-7/ -1 - (-4) --> -4/-1+4 --> -4/3
point slope form:
y - y1 = m(x-x1) ~ you can choose either of the two points to use, you should get the same answer
y - 3 = -4/3(x- (-1))
y - 3 = -4/3x+4/3
add 3 to both sides
y = -4/3x + 13/3 ~ slope intercept form
221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared.
In this case, area = (3.14 / 4) x (16.8 x 16.8)
