You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
Find the area of trapezoid.
1/2(6+10)(3) = 24
Now multiply 24 by $4 to find the total cost.
24 * 4 = 96
So the total cost is $96

Step-by-step explanation:
Answer:
1.84
Step-by-step explanation:
The given arc is a part of a unit circle centered at origin.
The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.
So, for angle equal to 
°, the x coordinate represents 
°.
So, 
° = 0.86
Similarly, the y-coordinate of angle y represent 
°.
So, ° = 0.98
Therefore, the value of ° + ° = 0.86 + 0.98 = 1.84.
34+56=90 this is your answer
Hope this helps lol
