We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope

patriot [66]
Even if they both spent all of their money, they would still be $0.43 short.

Leon’s $65 and Jennas $50 makes $115. Since they need $115.43, it doesn’t matter how they split the money as they wouldn’t have enough

Hope this helps :)

What is the distance between 3, 5 and -4, 1
USPshnik [31]

Answer:

Distance = 8.06

Step-by-step explanation:

We have to use the distance formula d=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}  }.

(x_{1},y_{1}) = coordinates of the first point

(x_{2},y_{2} ) = coordinates of the second point

To solve, plug the appropriate values into the formula.

d=\sqrt{(-4-3)^{2} +(1-5)^{2} } = \sqrt{65} = 8.062257748

At a local health club, a researcher samples 75 people whose primary exercise is cardiovascular and 75 people whose primary exer
ivolga24 [154]

Answer:

A

Step-by-step explanation:

Basically, this is an observational study because the researcher does not apply any treatment.

It's not an experiment because there is no experimentation involved. :)

It's not double-blind because in that case the researcher would have to apply something to two kinds of groups. one aware one the other not. not the case.

It's not D because  The observations are comparing two kinds of subjects and they are not looking for a cause and effect.

Descriptive statistics ___________, while inferential statistics ______________. are measures of central tendency; are measures
Leviafan [203]

Answer:

Descriptive statistics <u>describe data from surveys and case studies,</u> while inferential statistics <u>determine if data can be generalized to other populations</u>.

Step-by-step explanation:

Let's look at the definition of each type of Statistics

Descriptive Statistics, as the name says, describes, properties or characteristics (that can be gathered through surveys and case studies), using mathematical methods for tendency and dispersion.

Inferential statistics, as the name states, infers, if samples from a larger data set have behaviors that can be then extrapolated to the larger group.
