82 percent turns into 82/100
That then becomes 41/50 when simplified
Answer = 41/50
Answer:36
Step-by-step explanation:
The easiest way to solve this problem is to make a table, based on 100 total person
Prefer week ends Prefer week days Total
Female 10 55 65
Male 15 <span>20 </span>35
Total 25 75 100
The bold numbers are conclusions. The plain numbers are data.
<span>The probability that a randomly selected club member is female, given that that person prefers swimming on weekends</span> is [10 / 25] = 0.40
Answer: option D. 0.40
Answer:
Choice 4 (s - 3 = 12)
Step-by-step explanation:
I think you made a reading error on this question, as it said "for which equation is s = 9 <em>not</em> the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable <em>s</em> of each equation.
1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.
2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.
3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.
4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.
Choice 4/D is the correct choice.
The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.
<h3>What is a perfect trinomial?</h3>
A perfect square trinomial is takes the algebraic expression form ax^2 +bx + c, where the square root of the first term and the third term is the equation to the second term.
Given that:
-(3x + 5)^2
Open brackets
= - (9x +30x + 55)
Multiply through by (-)
= -9x^2 - 30x - 55
Therefore, we can conclude that the given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial. i.e. the multiplication of the square root of the first and the third term did not result in the 2nd term.
