Evaluate the discriminant of each equation. Tell how many solutions each equation has and whether the solutions are real or imag

Elena L [17]

All these equations are in the form of ax^2 + bx + c = 0, where a, b, and c are some numbers. the discriminants of equations like this are equal to b^2 - 4ac. if the discriminant is negative, there are two imaginary solutions. if the discriminant is positive, there are two real solutions. if the discriminant is 0, there is one real solution.

<span>x^2 + 4x + 5 = 0
</span>b^2 - 4ac
4^2 - 4(1)(5)

-4, two imaginary solutions.

<span>x^2 - 4x - 5 = 0
</span>b^2 - 4ac
(-4)^2 - 4(1)(-5)
16 + 20
36, two real solutions.

<span>4x^2 + 20x + 25 = 0

0, one real solution.

Mrs. Kozlova has a wonderful flower garden. She made sure that for every 18 mums she plants 12 tulips and for every 9 tulips the

Ivanshal [37]

Answer: The maximum numbers of rose bushes in garden is 16.

Explanation:

It is given that for every 18 mums she plants 12 tulips and for every 9 tulips there are 2 rose bushes.

Let the mums, tulips and roses are defined by M, T and R respectively.

From the given information,

$9T=2R$

$1T=\frac{2}{9}R$

$12T=\frac{2}{9}(12)R$

$12T=\frac{8}{3}R$

Since it is given that $18M=12T$ , we get,

$18M=\frac{8}{3}R$

$1M=\frac{8}{3(18)}R$

$1M=\frac{4}{27}R$

$110M=\frac{4}{27}(110)R$

$110M=16.296R$

From the above equation 110 mums we need 16.3 roses. So, the number mums exceeds 110 if the roses are 17.

Therefore, the maximum numbers of rose bushes in garden is 16 for which the number of mums cannot exceed 110.

Assume that that 10% of adults are left-handed. If 200 adults are randomly selected, find the probability that 16 or fewer of

Oxana [17]

Answer:

0.2078, not unusual

Step-by-step explanation:

Given that we assume that 10% of adults are left-handed.

Let X be the no of left handed persons in the sample of 200 adults

X is binomial because X has two outcomes and each trial is independent of the other

n =200 and p = 0.10

The probability that 16 or fewer are left-handed is

= $P(X\leq 16)\\= F(16)\\=\Sigma _0^{16} 200Cx (0.10)^x (0.9)^{200-x}$

=0.2075

Since nearly 1/5 are having chance to have left hand this is not unusual.
