Answer:
length of the legs is
Step-by-step explanation:
the both sides of the length of the legs of a right triangle are equal
So it form a isosceles triangle 45- 45- 90 degree triangle
the ratio of 45-45-90 degree triangle is
xsqrt(2) is the side opposite to 90 degree
so
Divide both sides by square root (2)
multiply square root (2) at the top and bottom
length of the legs is
Answer:
1.7 units
Step-by-step explanation:
Let (1.6,0.1) be (x1,y1) and (2.4,1.6) be (x2,y2)
By using distance formula,
d= sqrt (x2-x1)^2 + (y2-y1)^2
=sqrt (2.4-1.6)^2 + (1.6-0.1)^2
=sqrt (0.8)^2 + (1.5)^2
=sqrt 0.64+2.25
=sqrt 2.89
=sqrt (1.7)^2
=1.7
Therefore,the distance between them is 1.7 units

Answer:
Correct option: e) a two-way table.
Step-by-step explanation:
In this case the store wants to see whether there is a relationship between the satisfaction level of the customer and their gender.
In statistics when there is a need to analyze or derive a relation between two categorical variables one should use a two-way table.
Categorical variables are qualitative variables that take on specific values that are usually labels. For example, grades obtained in an exam, gender, etc.
In this case the two categorical variables are: Gender and Satisfaction level.
To study the relation between the gender of a customer and their satisfaction level use a two-way table.
