The range would be [-4, infinity) because range is the y-value. The lowest y-value is -4. The greatest y-value goes up to infinity.
Well you first would divide 239 by 6 which is 39.8333333 then you would divide 239 by 6 again and add those two together which would by 79.6666666 and then you will round you answer (or don't if your teacher told you other wise) to the nearest whole number which would give you your answer 80 people in the first twelve rows.
Answer:
The correct option is;
C. (1.6, 1.3)
Step-by-step explanation:
Given that at x = 1.5 the y-values of both equations are y = 1.5 and y = 1 respectively
The x-value > The y-value
The difference in the y-values = 1.5 - 1 = 0.5
At x = 1.6 the y-values of both equations are y = 1.2 and y = 1.4 respectively
The x-value > The y-value
The difference in the y-values = 1.2 - 1.4 = -0.2
At x = 1.7 the y-values of both equations are y = 0.9 and y = 1.8 respectively
The x-value > The first y-value and the x-value < the second y-value
The difference in the y-values = 0.9 - 1.8 = 0.9
Therefore, the approximate y-value can be found by taking the average of both y-values when x = 1.6 where the difference in the y-values is least as follows;
Average y-value at x = 1.6 = (1.2 + 1.4)/2 = 1.3
Therefore, the best approximation of the exact solution is (1.6, 1.3)
By calculation, we have;
-3·x + 6 = 4·x - 5
∴ 7·x = 11
x = 11/7 ≈ 1.57
y = 4 × 11/7 - 5 ≈ 1.29
The solution is (1.57, 1.29)
The exponential model is the most appropriate model for the given data.
<h3>How to determine the appropriate model?</h3>
The table of values is given as:
x 0 1 2 3 4 5
y 4 8 15.9 32 65.2 128
From the above table, we have the following highlights:
- The value of x increases by 1
- The value of y doubles by (approximately) 2
The above highlights is similar to an exponential model, because an exponential model has a constant multiplicative rate
Hence, the appropriate model is the exponential model
