MAVERICK [17]2 years ago

Answer:

B. 3

Step-by-step explanation:

To find the value of c, substitute the x and y values of the given point into x and y of the equation, then isolate c. Since that given point is (2,5), substitute 2 for x and 5 for y:

(5) = -2(2)^2+8(2)-c\\5 = -2(4)+16-c\\5 = -8 + 16 - c \\5 = 8 -c\\-3 = -c\\c = 3

Thus, c = 3.

DochEvi [55]

From the table given

17 people have managed care plan

9 have Traditional insurance

6 have no insurance

The probability of an event happening is given as the ratio of the number of the possible outcome divided by the total outcome.

If two balls are taken, the probability that at least one has traditional insurance

TN or TM or TT or NT or MT

where T is for traditional insurance

N is for no insurance

M is for managed insurance

the probability that at least one of two people picked without replacement has traditional insurance

= 9/32 * 6/31 + 9/32 * 17/31 + 9/32 * 8/31 + 6/32 * 9/31 + 17/32 * 9/31

= (54 + 153 + 72 + 54 + 153)/992

= 486/992

= 243/496

there are 3 slices of pie left, and the angle measurement is 72 degrees, how many slices was the pie cut in to
Daniel [21]
15; this is because 3 pies make up 72
with this you can make it so that 3x=72 
After this you need to find x which is a single pie
so; (3x/3)=(72/3)
      x= 24
Since you know a circle is 360 degrees all around the center
You can do 360/24 making it 15 pies.

a comedy show sells lower level tickets for $78 and upper level tickets for $59. on the opening knight 2368 tickets were sold fo
shusha [124]
Let L represent lower level tickets and U upper level.

Starter equations:
L + U = 2368
78L + 59U = 157800

Solve simultaneous equations:
59L + 59U = 139712
so 19L = 18088
L = 952
U = 2368 - 952 = 1416

952 lower level tickets and 1416 upper level tickets were sold.
