Answer:
1
Step-by-step explanation:
5(0)+1=1 because 5x0=0 then add the 1
Answer:
1.10
Step-by-step explanation:
Given the probability distribution :
x : ___ 0 ___ 1 ___ 2
p(x)__0.15 _0.60 __0.25
The expected value is obtained by:
Σ(X * p(x))
(0 * 0.15) + (1 * 0.60) + (2 * 0.25)
0 + 0.60 + 0.50
= 1.10
To find the inverse, we need to solve for x in term of f(x)
f(x) = 5x + 4
5x + 4 = f(x)
Solve for x
5x + 4 = f(x)
5x = f(x) - 4
x =
x acts as the invers of f(x), and f(x) is the invers of x, so the inverse function will be
f⁻¹(x) =
Answer:
(a) Circle Q is 9.4 units to the center of circle P
(b) Circle Q has a smaller radius
Step-by-step explanation:
Given
Solving (a): The distance between both
The equation of a circle is:
Where
P and Q can be rewritten as:
So, for P:
For Q:
The distance between them is:
Where:
---
---
So:
Solving (b): The radius;
In (a), we have:
--- circle P
--- circle Q
By comparison
<em>Hence, circle Q has a smaller radius</em>
Answer:
Step-by-step explanation:
Given the inequality you can follow these steps to solve it:
- The first step is:
Subtract 1 from both sides on the inequaltity.
Then:
- The second and final step is:
Divide both sides of the inequality by 2.
Therefore, you get:
