Probability is the study of determining the chances of an event being successful or not. To determine the probability of, say, 5 events happening, you would have to add their individual probabilities. For the probability of household having less than 3 televisions, you add the data for 2, 1 and 0 televisions.

Total Probability = 3% + 11% + 28% = 42% (or 0.42 if in decimal form)

The sum of a whole number and twice its square is 21. Find the whole number
I am Lyosha [343]
SOLUTION:

Let whole number = x

x + 2x^2 = 21

2x^2 + x - 21 = 0

2x^2 + 7x - 6x - 21 = 0

x ( 2x + 7 ) - 3 ( 2x + 7 ) = 0

( 2x + 7 ) ( x - 3 ) = 0


2x + 7 = 0

2x = - 7

x = - 7 / 2

OR

x - 3 = 0

x = 3


ANSWER:

Therefore, as 3 is a whole number while - 7 / 2 isn't a whole number, the whole number must be 3.

Hope this helps! :)

Jennifer works 3 1/2 hours each morning at the clinic. How many routine physicals could she complete in one morning? (Routine ph
den301095 [7]

Answer:

C

Step-by-step explanation:

Total Work hours = 3 1/2 hours

One routine physical routine requires: 1/3 hours.

Number of routines can be completed = Total work hours / Time required for one physical routine

= 3\frac{1}{2}  / \frac{1}{3}\\=\frac{7}{2} /\frac{1}{3} \\=\frac{7}{2} *3\\

= 10.5 routines.

In this case, we are unable to complete half a routine (0.5), so we will choose the highest possible whole number, in this case, its 10 routines.
