Answer:
0.5
Step-by-step explanation:
We are given that
Number of data value=2105
Sum of data values=1008.08
We have to find the average .
We know that
Average=
Using the formula
Average=
Average=0.47
Hence, the average=0.5
Answer:
x = 60
Step-by-step explanation:
By applying mean ratio theorem in the given right triangles ΔABC and ΔBDC,

BD² = AD × DC
BD² = 36 × 64
BD = 
BD = 48
By applying Pythagoras theorem in right triangle ΔADB,
AB² = AD² + BD²
x² = (48)² + (36)²
x² = 3600
x = 60
Let me change this equation up a bit...
x - 4y = -16....same as ur equation in the problem...just a different form
now its just a matter of subbing
when y = 5
x - 4(5) = -16
x - 20 = -16
x = -16 + 20
x = 4
so the first space on ur table above the 5 is 4
no need to go further...answer B
I would just add every job for a whole year then youll see which is better opton
