Use quadrratic equation discriminant
for
ax²+bx+c=0
if b²-4ac is the discriminant
if it is greater than 0, then it has 2 real number solutions
if it is equal to 0 then it has 1 real number solution
if it is less than 0 then it has 0 real number solutions
so
1x²+3x+j=0
b²-4ac=3²-4(1)(j)
9-4j
to have it have a real number solution, it must be greater than 0
9-4j>0
9>4j
9/4>j
j<9/4 is the solution area
Answer:
Each friend will get<u> 3 </u>pears.
Step-by-step explanation:
The question is incomplete and the complete question is:
Jen has 3 bags of pears. Each bag has 5 pears. If Jen gives the same number of pears to 4 friends, how many pears will each friend get?
Now, to find the number of pears each of the 4 friends get:
So, as given:
Number of bags of pears = 3.
Number of pears each bag has = 5.
Thus:
Total number of pears = 
Total number of friends = 4.
So, to get the number of pears each get we divide total number of pears by total number of friends:
<u><em>Thus, if Jen gives same number pears to 4 friends 3 pears each will get.</em></u>
Therefore, each friend will get 3 pears.
X=-3 because 5x-3=-15, -15-7 =-22
Answer:
<h2>The answer here would be <u>Statistic</u>.</h2>
Step-by-step explanation:
- In Statistics,Statistic is a term which refers to the values or estimates obtained from the sample to evaluate the actual population parameters.
- In this instance,observe that the average lifetime of the sample of 500 batteries tested comes out to be 225 hours., which is used to estimate the actual average lifetime of all the batteries developed by the company,which is also the population of interest in the concerned study.
- Hence,the average lifetime of the sample of 500 batteries of 225 hours is a sample Statistic which can be tested to determine the actual average lifetime of the all the batteries produced by the company.
