So you have to find 15 percent of 900 which would be 135
Answer : Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
GOOD LUCK
Mike biked 10 miles in 1.5 hours. Mila bikes at the same rate too.
Therefore, she will bike x miles in 3.5 hours
(10/1.5) = (x/3.5)
You cross multiply
1.5x = 10 x 3.5
1.5x = 35
x = 35/1.5
x = 23 miles (approximately)
I hope this helps
Answer:
y = -0.85 + 0.09x; $49.82
Step-by-step explanation:
1. Calculate Σx, Σy, Σxy, and Σx²
The calculation is tedious but not difficult.
2. Calculate the coefficients in the regression equation
To two decimal places, the regression equation is
y = -0.85 + 0.09x
3. Prediction
If x = 563,
y = -0.85 + 0.09x = -0.85 + 0.09 × 563 = -0.85 + 50.67 = $49.82
(If we don't round the regression equation to two decimal places, the predicted value is $50.56.)
