43.85 + (2*2.70) - (2*1.10) - 4.45 = $42.60
Or more simply 43.85 + 2.70 + 2.70 - 1.10 - 1.10 - 4.45 = $42.60
Answer:
<u>The correct answer is A. 109</u>
Step-by-step explanation:
1. Let's review all the information given to answer the question correctly:
Mean of candies in bags = 145
Standard deviation = 3
Number of bags of candies on a shelf = 160
2. About how many bags of candies are expected to have between 142 candies and 148 candies?
Let's recall that in a normal distribution, the 68.2% of the sample or the population is between minus one and plus one time the standard deviation.
For our case, the 68.2% of the bags of candies are expected to have between minus one time the standard deviation (145 - 3) and plus one time the standard deviation (145 + 3).
<u>It means that 109 bags (0.682 * 160) are expected to have between 142 and 148 candies. The correct answer is A. 109.</u>

Answer:
D.) (5,31)
Step-by-step explanation:
Since they already gave you the value of x
plug that into the equation for y
y=6(x)+1
y=6(5)+1
y=30+1
y=31
Therefore, you have
x=5 and y=31
