Is the discriminant of g positive, zero, or negative?
Answer:
The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.
Step-by-step explanation:
The discriminant of the quadratic equation g is negative.
In algebra, the discriminant of a quadratic equation plays a crucial role in determining the nature of its roots. For a quadratic equation of the form ax² + bx + c = 0, the discriminant is given by Δ = b² - 4ac. Depending on whether the discriminant is positive, zero, or negative, we can determine the types of roots the equation possesses.
When the discriminant is negative, it implies that the quadratic equation has no real roots. In this case, the graph of the quadratic equation does not intersect the x-axis at all, indicating that it has complex roots. These complex roots are a pair of complex conjugates of the form (p + qi) and (p - qi), where p and q are real numbers and i is the imaginary unit (√(-1)).

50% people use cellular mobile and 40% people use landline and 20% people use both. Find the probability that a person selected at random use neither.
a) 10% b) 30%
c) 70% d) 90%
Answer:
a) 10%
Step-by-step explanation:
To be able to own both (20%), you must fall into both categories. You own a cellular mobile, and you own a landline. The 20% is within the 50% + 40%.
50% + 40% = 90%
Subtract 90% from the total amount:
100 - 90 = 10
A) 10% is your answer.

i will mark you as brianilest The school band sold T-shirts to raise money for an upcoming trip. The band sold 400 T-shirts on Saturday and on Sunday, it will sell 30 percent of that amount. Which statements are true about the number of T-shirts that the band will sell on Sunday? check that all apply A. the answer will be less than 400 because 30 is less than 100 B. The answer will be greater than 400 because 300 percent is greater than 100 C. (100)(4)=400 so 30 (4) is the number of T-shirts the band will sell on Sunday. D. The band will sell 430 T-shirts on Sunday or E. The band will sell 120 T-shirts on Sunday.
Answer:
A and E
Step-by-step explanation:
A is correct because if you have less than 100 percent of something then the value will be less than the original value.
E is correct because 30 percent of 400 is 120 so the band will sell 120 t-shirts on Sunday.

In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 100 fewer people went to the pool than in the first week. In the third week, 140 more people went to the pool than in the second week. In the fourth week,146 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answer: 10%
Step-by-step explanation:
As per given ,
Initial number of people went to pool = 1060
After 4 weeks periods, number of people went to pool = 1060 - 100 +140 -146 ['+' for addition . '-' for decrease]
= 954
The percent decrease in the number of people who went to the pool over these four weeks = [tex]\dfrac{1060-954}{1060}\times 100[/tex]
[tex]=\dfrac{106}{1060}\times100\\\\=10\%[/tex]
Hence, the percent decrease in the number of people who went to the pool over these four weeks = 10%
Solve for x !!!!!!!!
Answer:
D) 4
Step-by-step explanation:
By remote interior angle property if a triangle, we have:
19x° + (18x - 4)° = 144°
(18x - 4 + 19x)° = 144°
(37x - 4)° = 144°
37x - 4 = 144
37x = 144 + 4
37x = 148
x = 148/37
x = 4

The sum of two numbers is 1633 and their difference is 35. Find the 2 numbers using simultaneous equation.
Please show working out
Answer:
Please Mark As Brainliest!!
834 and 799
Step-by-step explanation:
x+y=1633
x-y=35
2x= 1668
x=834
y=799
Answer:
((819.458,813.542)
Step-by-step explanation:
sum of two numbers=1633
x+y=1633----equation (i)
their difference=35
(x-y)^2=35----equation (ii)
solve simultaneous equation by using substitution method
x+y=1633
make x the subject of the formula
x=1633-y---(i)
substitute equation (i)into (ii)
(x-y)^2=3
(1633-y-y)^2=35
(1633-2y)^2=35
apply square root both sides
√(1633-2y)^2=√35
1633-2y=√35
-2y=√35-1633
-2y=-1627.08392
divide both sides by -2
y=813.5419601
substitute the value of y in equation (i
x=1633-y
x=1633-813.5419601
x=819.4580399
therefore the two numbers are (819.458, 813.542)
