The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories (in thousands) and x is years after 1960. Choose the correct statement.
Answer: In the given regression equation, the calories are in thousands. Therefore, the slope 0.005 (0.005 x 1000 =5 calories) means the consumption is increasing at a rate of 5 calories per year.
Hence the option a. Consumption is increasing at a rate of 5 calories per year. is correct
Answer:
√3/10 = 0.1732
Step-by-step explanation:
√15 / 5√20 = (√5 x √3) / 5(√5 x √4) = √3 / (5 x√4) = √3 / 10

positive
Step-by-step explanation:
multiplication of of negetive values is positive
multiplication of positive value and negetive value is negetive
Answer:
Step-by-step explanation:
Lets say Rhonda drove x miles, then Jamie drove 2x miles
x+2x=90
3x=90 divide each side by 3
x=30
so Rhonda drove 30 miles and Jamie drove 30*2=60 miles
Let's write the equation in standard from
Where,
- m is slope or rate of change
- b is the y-intercept or initial value
<h3>Let's start by finding slope⤵️</h3>
- x1, y1 = 0,12
- x2, y2 = 1,13
