Answer:
In 4 months, they will both have 132 stamps.
Step-by-step explanation:
Let x = # of months
52 + 20x = 68 + 16x
4x = 16
x = 4
Plug x value into both expressions and see if it checks out
52 + 20(4) = 68 + 16(4)
52 + 80 = 68 + 64
132 = 132
Answer:
And replacing:
And the deviation:
And the distribution is given:
Step-by-step explanation:
For this case we have the following info given :
And the deviation would be 
For this case we select a sample size of n = 5 and the distirbution for the sample mean would be:
And replacing:
And the deviation:
And the distribution is given:
No there are 96 inches in 8 feet because,
12 inches = 1 foot
12 x 8 = 96
so there are 96 inchs in 8 feet

Step-by-step explanation:
Answer:
After the reflection over the line y = -x, the image of the point is: (-3,-2)
Step-by-step explanation:
When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.
Let (x,y) be a point on the plane
and
y = -x be a line on the plane
When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated
So (x,y) will become (-y,-x)
Given point is:
(2,3)
After the reflection over the line y = -x, the image of the point is: (-3,-2)
