Answer:
24 right handed students
Step-by-step explanation:
1. Out of every 5 students, 4 are right handed and 1 is left handed. We can say that 1/5 of the class is left handed.
2. Multiply 30 by 1/5 to get 6 left handed students in the class.
3. Take the 30 students in the class and subtract the 6 left handed students.
4. The remaining 24 students must be right handed.
Answer:
y=1//4x+1.5
Step-by-step explanation:
3=1/4(6) +C
3=1.5+C
3-1.5=C
1.5=c
Vietas formula tells us that the product of our two roots is equal to the constant term of a quadratic over the leading coefficient, so:
[tex] r_1r_2=-\frac{-10}{2} \implies 5*r_1=-5 \implies r_1=-1[\tex]
It also tells us that the b term in our quadratic is equal to the negative of the sum of the terms divided by the leading coefficient, so:
[tex] r_1+r_2=-\frac{b}{2} \implies 4=-\frac{b}{2} \implies b=-8 [\tex]
So, one of our roots is 5, the other is -1, and our b value is 8.
