Answer:
a. 104
b. 102, 104, and 105
Step-by-step explanation:
a. There are 13 data points plotted on the dot line. The median lies between the 6th and 7th data point.
Thus, on the dot line, the 6th and 7th data points both fall on 104.
Therefore, median = 104
b. The dot plot shows the high temperatures that occurred more than one day are:
102, 104, and 105
In order to solve this, we need to select the function that meets our constraints. Since x^2 - 5 occurs when x is less than 3, and the x-value we are given is -4, we use the first function.
f(-4) = (-4)^2 - 5
f(-4) = 16 - 5
f(-4) = 11
From the reference of the 18 degree angle, 'h' is the opposite side and 100 is the adjacent side.
The trig ratio which uses both the opposite and adjacent sides is the tangent.
tan(18) = opp/adj = h/100
Trig equation:
tan(18) = h/100
From the 8th to the 13th there are five numbers, and the difference between the 8th and the 13th is 20-12.5=7.5, so the difference between two neighboring number is 7.5÷5=1.5
from the 13th and the 25th there are 12 numbers, so the total difference is 12*1.5=18
so the 25th term is 20+18=38
