First arrange in ascending order of time:-
7, 8, 10, 12, 14, 15, 18, 20, 26, 30, 30, 30, 35, 35, 42, 55
MOde is the value occuring mos = 30.
Median is the mean of 2 middle numbers = (20 + 26) / 2 = 23
Mean = sum of the 16 numbers / 16 = 387/16 = 24.2
(141 + 162 + S) / 3 = 160
(303 + S) / 3 = 160
101 + S/3 = 160
-101 -101
S/3 = 59
*3 *3
S= 177
Jacques needs at least a 177 to get a 160 average
Answer:
h(x-5)=2x-5
Step-by-step explanation:
What we want to do is replacing x-5 with x and we got h(x-5)=2(x-5)+5, using the distributive property and simplify to the simplest expression is going to be h(x-5)=2x-5
