This is binomial probability with n=50 and p=0.62.
We want binom(50,0.62,35).
One way to calculate this is to use a calculator with statistical functions.
My TI-83 Plus turned out the result 0.061.
Answer:
<em>1. </em><em>B. $20</em>
<em>2.</em><em>C. 19%</em>
<em>3. </em>D. not here
Step-by-step explanation:
1. info we know
25+45+10+25+15+10 = 130
we need 20 more dollars
2. 25/130 x/100
cross multiply
2500/ 130x
divide
19 = x
3. same steps as last time
35/130 x/100
3500/130x
29%
Answer: OPTION C.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Notice that the line of f(x) is dashed. This means that the symbol of the inequality must be
or
.
Since the shaded region A is above the line, the symbol is 
Observe that its y-intercept is:

The line of g(x) is solid. This means that the symbol of the inequality must be
or
.
Since the shaded region B is below the line, the symbol is
.
Observe that its y-intercept is:
.
Based on this, we can conclude that the graph represents the following System of Inequalities:
