The probability that a student who does not have a dog has a cat is 7/10.
<h3>What is the probability?</h3>
Probability determines the chances that a random event would happen. The odds that the random event would happen lies between 0 and 1.
The probability that a student who does not have a dog has a cat = number of students that do not have a dog but has a cat / total number of students that do not own a dog
= 7/10.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
5x² - 2 = -12
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 2 on both sides: 5x² = -10
- [Division Property of Equality] Divide 5 on both sides: x² = -2
- [Equality Property] Square root both sides: x = ±√-2
- Rewrite: x = ±√-1 · √2
- Simplify: x = ±i√2
Answer:
Step-by-step explanation:
Given:
Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;
Step 2: Now we will try to make the denominator common so we will get;
Step 3: Now from the number line when we subtract 
from 
we get number of spaces left are - 7
Hence now it will become:
Hence the final Answer is
Answer:
Step-by-step explanation:
Given f(x)=
We have to find 
In order to find 
we have to make x as the subject of the formula
Let us assume f(x)=y
⇒
Subtracting both sides by 5
Dividing both sides by 2
⇒
Now substituting y with x
we have 
Now 
=
So option (ii) is correct
