Answer:
0.487 kg
b.) the newborn weighs 0.487kg more than the weight predicted by the regression equation
Step-by-step explanation:
Given the Regression equation:
Weight = - 5.58 + 0.1686 length
Length of newborn = 48 cm
Actual Weight of newborn = 3kg
Predicted weight from regression model:
Weight = - 5.58 + 0.1686(48)
Predicted Weight = 2.513kg
Hence, residual = (Actual - predicted)
Residual = (3kg - 2.513kg) = 0.487kg
Since the actual weight is more or greater than the predicted weight:
b.) the newborn weighs 0.487kg more than the weight predicted by the regression equation
2.5*7=17.8 days or 18 whole days
18*25.50=459

Answer:
16.6
Step-by-step explanation:
Given:
m<C = 36°
a = 9.4
b = 6
This information given shows that it is a ∆ with two known side lengths and an included angle that lies between the two given sides.
Therefore, the formula, ½*a*b*sin(C), can be used in solving the area of the ∆.
Plug in the values:
Area = ½*9.4*6*sin(36)
Area = 9.4*3*sin(36)
Area = 16.6 units² (nearest tenth)
Answer:
Let's say someone is selling lemonade at a lemonade stand. The more cups of lemonade this person sells, the more money they get. If 1 cup= $1, then he would get $2 for 2 cups.
Step-by-step explanation:
The price of the lemonade cup and the lemonade cup are a constant of proportionality. They are proportional to each other. The more lemonade you sell, the more money you get.
The graph would be a straight diagonal line. The y would be the money, and the x would be the amount of lemonade sold. Since they are the same and proportional, they would go in a straight line.
