First you graph "y = 2x +2." You shade in the region below it, because it's y "LESS THAN" and you keep the line solid (not dotted) because it's "equal to" 2x+2 too.
<span>Answer:
1. B increases
2. </span><span>D 4
</span><span>3. A. every 15 minutes
The exponent function can be described as an= a0(r)^n where
a0= the initial value
r= the ratio of growth of decay
n= the time
In this question, the initial value would be 120, the ratio would be 1.04 and the time would be 4t.
The ratio is 1,04 or can be said as 104%. The graph should be growing since the ratio is >1. So, the first answer is increases.
The ratio is 104% which means 4% more than the original value(100%). So the next answer would be 4%.
The time used in the graph is 4t and the unit used by t is hours. That means, the growing happens for every 1/4 hour. If you change it into minute, it would be: 1/4* 60 minutes/hour= 15 minutes</span>
Answer:
Step-by-step explanation:
Answer:
3000 bags
Step-by-step explanation:
In this case we must apply the formula of the mean, which would be the sum of the values divided by the amount of data is the mean:
m = (a1 + a2 ... an) / n
In this case we know the mean, we must know the 1987 data, therefore:
Let x be the number of bags sold in 1987, replacing in the previous equation:
2100 = (1800 + 1500 + x) / 3
2100 * 3 = 3300 + x
x = 6300 - 3300
x = 3000
Therefore, for the average to be a total of 2100 bags in those 3 years, the amount of bag sold in 1987 must have been 3000 bags
