Answer:
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.
Step-by-step explanation:
100 centimeter in a meter
100*1=100
Given:
Joey had 26 game cards.
His friend Richard gave him some more, and now Joey has 100 cards.
To find:
How many cards did Richard give to Joey?
Solution:
Let x be the number of cards that Richard give to Joey.
Joey had 26 game cards.
Now, the total cards joey has 
Joey has total 100 cards.



Therefore, Richard gave him 74 cards.

Step-by-step explanation:
Pls take a state photo I can’t tell if it is a rectangle or a polygon
The first step is to locate the coordinates of the vertices of the arrow. From the graph,
A = (2, 1)
B = (2, 3)
C = (1, 3)
D = (3, 5)
E = (5, 3)
F = (4, 3)
G = (4, 1)
If (a, b) is reflected on the line y = - x, the coordinates of the image is (- b, - a)
By applying this rule, the new coordinates after reflecting the arrow over the line y = - x are
A'(- 1, - 2)
B'(- 3, - 2)
C'(- 3, - 1)
D'(- 5, - 3)
E'(- 3, - 5)
F'(- 3, - 4)
G(- 1, - 4)
