-2 and 2
-2 0 and 2
i hope this helps
you can try to pair ech of them and calculate like -2 with -1 no then -2 0 no -2 2 yes then with pair of three -2 -1 0 no etc-2 0 -2 yes
Answer:
15 units
Step-by-step explanation:
1. Find the corresponding lengths of the triangles.
9/x = x/ (9+16)
9/x = x/25
2. Solve for x.
Multiply both sides by x.
9 = x²/25
Multiply both sides by 25.
225 = x²
Square root both sides to solve for x.
√225 = √x²
x = 15
There is no distinct pattern, the scatter plot would be up down and spread apart, nothing really correlated.
Answer:
The numbers are -21 and 21
Step-by-step explanation:
Let
x ----> one number
y ----> another number
S----> the sum of their squares
we know that
----> equation A
----> equation B
substitute equation A in equation B
This is the equation of a vertical parabola open upward
The vertex is a minimum
Find the coordinates of the vertex
Using a graphing tool
The vertex is the point (21,882) ----> see the attached figure
we have
x=21
<em>Find the value of y</em>
therefore
The numbers are -21 and 21
Answer:
P (X<120)=0
Step-by-step explanation:
We can compute the probability for women:
μ=259 and σ=32
P ( X<120 )=P ( X−μ<120-259 )=P ((X−μ)/σ<(120−259)/32)
Since (x−μ)/σ =Z
and
we have:
Use the standard normal table to find this area.
Now we can find P ( Z<4.34 ) by using the standard normal table which is 1:
Therefore: P (X<120)=0
For men
μ=242 and σ=29
P ( X<120 )=P ( X−μ<120-242 )=P ((X-μ)/σ <(120-242)/29 )
Since (x-μ)/σ=Z
and
we have:
Use the standard normal table to find this area.
Now we can find P ( Z<4.21 ) by using the standard normal table which is 1:
Therefore: P (X<120)=0
