Suppose a horse is galloping at 19 mph toward a clown, and the clown is racing toward the horse on an ATV which can sustain a sp

Answer:

It will take 1.47 hours for the horse and clown to collide

Step-by-step explanation:

They are driving toward each other, in opposite directions.

So to find their speed of approximation, we add their speeds.

19 mph + 15 mph = 34 mph.

This means that each hour, they are 34 miles closer.

How long it takes for them to find each other if they are 50 miles apart?

1 hour - 34 miles

x hours - 50 miles

$34x = 50$

$x = \frac{50}{34}$

$x = 1.47$

It will take 1.47 hours for the horse and clown to collide

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d

JulijaS [17]

For the manager's store

Population size: 15
Arithmetic mean (μ): 37.6
Standard deviation (σ): 11,056

For the competitor's store

Population size: 15
Arithmetic mean (μ): 48,533
Standard deviation (σ): 28,356

For the manager's store the average is a better representation of the data since it does not have Outlier points in the box diagram. Also the median is close to the average.

For the competition store the average of the data collected is not as good representation of the data since they are dispersed from the mean with a standard deviation of 28.35. It also presents Outliers points in the box diagram, such as 112 which is very far from the average

Answer:

$(3,2)$

Step-by-step explanation:

The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

$y=-2x+8\\y=x-1$
