Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e.
.
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)

D>0 the roots are real and unequal
Function (2)

D<0 the roots are real and unequal
Function (3)

D>0 the roots are real and unequal
Function (4)

D>0 the roots are real and unequal
Function (5)

D<0 the roots are real and unequal
Function (6)

D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.
your answer for this question would be A)
Let's solve your equation step-by-step.<span><span><span>6x</span>−<span>2<span>x4</span></span></span>=<span>12x</span></span><span><span><span>−<span>2<span>x4</span></span></span>+<span>6x</span></span>=<span>12x</span></span>
Step 1: Subtract 12x from both sides.<span><span><span><span>−<span>2<span>x4</span></span></span>+<span>6x</span></span>−<span>12x</span></span>=<span><span>12x</span>−<span>12x</span></span></span><span><span><span>−<span>2<span>x4</span></span></span>−<span>6x</span></span>=0</span>
Step 2: Factor left side of equation.<span><span><span>2x</span><span>(<span><span>−<span>x3</span></span>−3</span>)</span></span>=0</span>
Step 3: Set factors equal to 0.<span><span><span>2x</span>=<span><span><span>0<span> or </span></span>−<span>x3</span></span>−3</span></span>=0</span><span><span>x=<span><span>0<span> or </span></span>x</span></span>=<span>−1.44225</span></span>
Answer:<span><span>x=<span><span>0<span> or </span></span>x</span></span>=<span>−1.44225 This is the answer if its exponent. The other might be:</span></span>
Step 1: Simplify both sides of the equation.<span><span><span>6x</span>−<span>2<span>(<span>4x</span>)</span></span></span>=<span>12x</span></span><span>
Simplify: (Show steps)</span><span><span>−<span>2x</span></span>=<span>12x</span></span>
Step 2: Subtract 12x from both sides.<span><span><span>−<span>2x</span></span>−<span>12x</span></span>=<span><span>12x</span>−<span>12x</span></span></span><span><span>−<span>14x</span></span>=0</span>

You never specified what the (x4) part was so I gave both.</span></span>
Answer:
5.80% probability that exactly 1 resume will be from females.
Step-by-step explanation:
For each resume received by the corporation, there are only two possible outcomes. Either they are from a female, or they are not. The probability of a resume received being from a female is independent from other resumes. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
22% of all resumes received by a corporation for a management position are from females.
This means that 
18 resumes will be received tomorrow.
This means that 
What is the probability that exactly 1 resume will be from females?
This is P(X = 1).


5.80% probability that exactly 1 resume will be from females.
