Please help me solve this problem, and someone please clearly explain to me how to solve it.

Step-by-step explanation:

For a trinomial ax² + bx + c = 0, the discriminant is b² − 4ac.

If the discriminant is positive, there are 2 real solutions.

If the discriminant is 0, there is 1 real solution.

If the discriminant is negative, there are no real solutions.

a) x² − 4x − 7 = 0

Here, a = 1, b = -4, and c = -7.

b² − 4ac = (-4)² − 4(1)(-7) = 44

The discriminant is positive, so there are 2 real solutions.

b) 4r² + 11r − 3 = 0

Here, a = 4, b = 11, and c = -3.

b² − 4ac = (4)² − 4(11)(-3) = 148

The discriminant is positive, so there are 2 real solutions.

c) 3m² + 7 = 0

Here, a = 3, b = 0, and c = 7.

b² − 4ac = (0)² − 4(3)(7) = -84

The discriminant is negative, so there are no real solutions.

d) t² + 2t + 1 = 0

Here, a = 1, b = 2, and c = 1.

b² − 4ac = (2)² − 4(1)(1) = 0

The discriminant is zero, so there is 1 real solution.

Sarawong is carrying six pages of math homework and four pages of english homework. a gust of wind blows the pages out of his ha

Eduardwww [97]

The sample space of the experiment (i.e. the total number of ways he can pick 7 random pages out of a total of 6 + 4 = 10 pages) is given by:

$^{10}C_7=120$

If he picks at least 5 pages of maths homework, this means that he either picked 5 pages or 6 pages of maths homework.

The number of ways he can pick 5 or 6 maths homework is given by:

$^6C_5+{ ^6C_6}=6\times1=6$

Therefore, the probability that he recovers at least 5 pages of his math homework is given by:

$\frac{6}{120} = \frac{1}{20}$
