Answer:
Blue cars, B = 63 cars
Step-by-step explanation:
Let the blue cars be B.
Let the red cars be R.
Given the following data;
Ratio of B:R = 9:7 = 9 + 7 = 16
Red cars, R = 49
To find the number of blue cars;
First of all, we would determine the total number of cars using the expression;
R = 7/16 * x = 49
7x = 49 * 16
7x = 784
x = 112 cars
Now, we can find the number of blue cars;
B = 9/16 * 112 
B = 1008/16
Blue cars, B = 63 cars
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Subtract the 4 from 9
 
        
                    
             
        
        
        
Here are a couple I found: 
<u>Similarities</u>: 
- They have the same y-intercept of (0,5). 
- They are both in slope-intercept form. 
<u>Differences</u>: 
- The line of y = -13x + 5 "falls" from left to right. The line of y = 2x + 5 "rises" from left to right. 
- They have different x-intercepts. (y = 2x + 5 intersects (- , 0) while y = -13x + 5 intersects at ( , 0) while y = -13x + 5 intersects at ( , 0) , 0)
<u></u>
<u>Explanation</u>:
Slope-intercept form is y = mx + b, and by looking at the equations, they both already fit that format, with m as their slope and b as their y-intercept. Also, since they both have a 5 as that "b," their y-intercepts are the same: (0,5). 
As for differences, we can see that the coefficient in place of that "m" is positive in y = <u>2x</u> + 5 and negative in y = <u>-13x</u> + 5. Therefore, one line would rise due to their slope being positive and one would fall due to their slope being negative. They also have two different x-intercepts, which we can calculate by substituting 0 in place of the y, then isolating x. 
 
        
             
        
        
        
Answer: The required probability is 0.008.
Step-by-step explanation:
Since we have given that 
Probability of bachelor's degree = 0.45
Probability of working in nursing = 0.85
Probability of both = 0.4
So, Probability of getting a graduate is currently working in nursing, given that they earned a bachelor's degree would be :

Hence, the required probability is 0.008.
 
        
             
        
        
        
Answer:
-11.5
Step-by-step explanation:
4(x-2/3)=-18
4x-8/3=-18
4x-8=-18×3
4x-8=-54
4x=-54+8
4x=-46
x=-46/4
x=-11.5
