Answer:
15x/2
Step-by-step explanation:
1) Using the information provided, form an expression.
2) To further clarify Step 1, a product is the result from multiplying two numbers.
3) To determine product you could either multiply, x * y or leave it as xy, which means the same thing. Most commonly we would leave it as xy
4) 15x represents the product of 15 and a number, since the number is not provided leave it as x.
5) Next divide this expression by two as stated.
Answer:
B (1)
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
14-12<3
Part A. The correlation coefficient, denotes as R^2, is a measure of how well does the data point correlate with a given model or equation. The closer the R^2 is to 1, the better is the correlation. However, R2=1 is ideal for scatter plots. Using the MS Excel to execute the regression, the data points was fitted to a quadratic equation. The R2=0.9983. From the choices, the closest answer would be 1. But as stated previously, a value of 1 is ideal only. Therefore, the answer is most likely 0.94,
Part B. To determine the slope, the equation would be Δy/Δx. For x=5 and x=10, the slope would be
Slope = (3-1)/(10-5) = 2/5 or 0.4. This is the instantaneous rate of change at the interval of 5 to 10 days.
Part C. The difference between causation and correlation is identifiable if you know the direct relationship between the variables. In this case, the increase in radius is not caused by time. The problem does not state so. But we know from the trend shown on a graph, that there is a correlation between these variables. Therefore, the answer is correlation.
Answer:
It is 20%.
Step-by-step explanation:
You minus 28 from 35 it will give 7 and then take 7 x 100 / 35 which will give you 20%
