The answer is A because 13 times 6 equals 78
Answer:
The correct answer is 2.45.
Step-by-step explanation:
Probability model of an office manager regarding reports from employees is given by:
X = 0; P(X) = 0.05
X = 1; P(X) = 0.15
X = 2; P(X) = 0.35
X = 3; P(X) = 0.25
X = 4; P(X) = 0.15
X = 5; P(X) = 0.05
Now expectation of number of emails that the manager would receive is given by X × P(X)
= 0 × 0.05 + 1 × 0.15 + 2 × 0.35 + 3 × 0.25 + 4 × 0.15 + 5 × 0.05
= 0 + 0.15 + 0.70 + 0.75 + 0.60 + 0.25
= 2.45
Angle 3 = angle 7 [alternate angles]
=> 4x+1 = 2x + 21
=> 4x-2x = 21-1
=> 2x = 20
=> x = 20/2
=> x = 10
Answer:
117
Step-by-step explanation:
6/8 x/156 so 156/8=19.5*6=117
3 1/2 is one answer Hope this helps! Hit that thanks button and rate 5 stars for brainliest answer! Have a nice day :)
