Imagine a regression line that relates y = average systolic blood pressure to x = age. The average blood pressure for people 40

mart [117]

Answer:

2.0

Step-by-step explanation:

x = age

y = average systolic blood pressure

x₁ = 40 years old, y₁ = 110 systolic blood pressure

x₂ = 50 years old, y₂ = 130 systolic blood pressure

$\text{Slope of a line}=m=\frac{y_2-y_1}{x_2-x_1}\\\Rightarrow m= \frac{130-110}{50-40}\\\Rightarrow\frac{20}{10}\\\Rightarrow m= 2.0$

∴ Slope of the regression line is 2.0

Amia has $300 to plan a trip with her cousins. She wants to go to Orlando, Florida and it costs $127 for a room, $75 for gas rou

zhuklara [117]

First let's add the room cost and the gas.

127+75= 202

Let's subtract that from 300.

300-202= 98

Divide 98 by 20.

20 can only go into 98 4 times.

Amia can only bring 3 cousins, since one of those 4 tickets are for her.

I hope this helped you.

Brainliest answer is always appreciated.
