Answer:
Step-by-step explanation:
When we say factor and solution, we mean to say the same thing. These terms may also sometimes be referred to as "roots". There is a law in mathematics which states that the number of solution in a given equation is equal to the highest exponent in the expression and for quadratic equation, the number of solutions should be 2.
Probability always sums up to 1
P(pizza) + P(cheeseburger) + P( chicken sandwich) + P(caesar salad) + P(macaroni and cheese) = 1
let P(caesar salad) be x
0.2 + 0.45 + 0.06 + x + 0.12 = 1
x= 0.17
Answer:
2/3
Step-by-step explanation:
In a year, we have 52 weeks.
Since he is supposed to have a new order for every two weeks, he needs 52/2 = 26 orders to break the company record.
After 28 weeks, he has got only 28/2 = 14 orders.
He is 4 orders behind. So he has done 14 - 4 = 10 orders.
The sales man needs 26 - 10 = 16 more orders .
Although 28 weeks is gone, we have 52 - 28 = 24 weeks left.
If he needs to make 16 sales in 24 weeks, the proportion is 16/24 = 2/3
He needs to make 2 sales every week to break the record
Graphically: graph your equations and look for the intersections (these are your answers).
Algebraically: set your equations into y = format (below) and plug your values into the quadratic formula.
y = ax^2 + bx + c
(example: y = 2x^2 + 5x + 6; a = 2, b = 5, c = 6)
