If there are 14 different scenarios that can happen (Blue 1-5, Green 1-6, Red 1-3), and 9 of them are not blue, there is a 9/14 chance that the first pick is not blue. to get percentages, you divide 9 by 14 to get 0.64, or 64 percent chance at not picking blue.
Answer:
n = 15.5
Step-by-step explanation:
(4+n)/(43+n) =1/3
3(4+n)= 1*(43 + n)
12 + 3n = 43 + n
3n - n = 43 - 12
2n = 31
n = 31/2= 15.5
Answer:
1/10x * 1/10x
Step-by-step explanation:
Writing a term with negative exponents is the same as putting it in a fraction.
10x^-1 = 1/10x
so the expression would be
1/10x * 1/10x
Answer:
<em>The age at which both companies charge the same premium is 44 years</em>
Step-by-step explanation:
<u>Graph Solution to System of Equations</u>
One approach to solving systems of equations of two variables is the graph method.
Both equations are plotted in the same grid and we find the intersection point(s) of both graphs. Those are the feasible solutions.
The annual premium p as a function of the client's age a for two companies are given as:
Company A: p= 2a+24
Company B: p= 2.25a+13
The graphs of both functions are shown in the image below.
The red line indicates the formula for Company A and the blue line indicates the formula for Company B.
It can be seen that both lines intersect in the point with approximate coordinates of (44,112).
The age at which both companies charge the same premium is 44 years
