Answer:
425
Step-by-step explanation:
Stamps from Canada are: 55
But Scott has 315 more stamps from the u.S. Than from Canada, so his stamps from U.S are: 315 + 55 = 370
=> the total number of stamps he has in his collection
= Stamps from Canada + stamps from U.S
= 55 + 370
= 425
Hello!
Solve for x:
4(2x+25)=20
Distribute the 4 to the numbers inside the parenthesis.
8x + 100 = 20
Subtract 100 from both sides of the equation to get 8x by itself.
8x = -80
Divide both sides by 8
x = -10
The equation of the line is y = 3x + 8
<h3>How to determine the equation?</h3>
The equation is given as:
y = 3x - 5
A linear equation is represented as:
y = mx + b
Where m represents slope;
This means that:
m = 3
Let the slope of the required line be n.
Since the lines are parallel, then
n = m = 3
The linear equation is then calculated as:
y = n(x - x1) + y1
Where:
(x1,y1) = (-2,2)
This gives
y = 3(x +2) + 2
Expand
y = 3x + 8
Hence, the equation of the line is y = 3x + 8

Answer:
15/x-2
Step-by-step explanation:
Cant attach the photo but you use a division table
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
