Answer: I think its B
Step-by-step explanation: hoped this helped :)
Thank you for posting your question here at brainly. I hope the answer will help. Belowis the solution:
Let X be a random variable for the Celtics score. Then you want
<span>P(X > 101.7) </span>
<span> 1 - P(X < 101.7) </span>
<span> = 1 - P((X - μ)/σ < (101.7 - 99.2)/10.5)) </span>
<span> = 1 - N_Z(0.2381) </span>
Number of people that chose salad = 81
Percentage of people that chose salad over meat dish = 27%
Let us assume the number of people on the survey = x
Then
27% * x = 81
(27/100) * x = 81
27x = 81 * 100
27x = 8100
x = 8100/27
= 300
So a total of 300 people participated in the survey.I hope the procedure is clear enough for you to understand. Based on this method you can always solve similar types of problems without requiring any kind of help from outside.
slope = - 
calculate the slope m using the gradient formula
m= (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 3, 6)
m = 
= 
= -
