Answer:

Step-by-step explanation:
-The total number of outcomes is 4.
-Given that the outcomes occur with the same frequency.
-Therefore they all occur with the same frequency, 1/4=0.25

-The probability distribution for the duration of a service call is attached.
The values that complete the conversions are
a = 10000
b = 100
c = 1000000
<h3>Conversion of units </h3>
From the question, we are to complete the given conversions
i)
1 m² = a cm²
NOTE: 1 m² = 10000 cm²
∴ a = 10000
ii)
1 cm² = b mm²
NOTE: 1 cm² = 100 mm²
∴ b = 100
iii)
1 km² = c m²
NOTE: 1 km² = 1000000 m²
∴ c = 1000000
Hence, the values that complete the conversions are
a = 10000
b = 100
c = 1000000

Answer:
Angle EDF= 53
Step-by-step explanation:
Supplementary angle: Angle EDC and angle EDF
which means angle EDC+ Angle EDF=180
Angle EDC show in the graph 127 degree
Angle EDG= 180-127=53Degree
3 because you add each exponent in a trinomial.
