Answer:

76

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c : a ≠ 0, then

the discriminant Δ = b² - 4ac

Given

3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10 and c = 2

b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76

Answer:

Discriminant : 74 .

Step-by-step explanation:

Given : 3x² - 10x = -2.

To find : Find the discriminant .

Solution : We have given  3x² - 10x = -2.

On compare with standard form ax² +bx +c = 0.

Where, a =3 ,b = -10 , c = 2.

Discriminant : b^{2} - 4ac.

Plug the values of a , b , c .

Discriminant : (-10)^{2} - 4(3)(2).

Discriminant : 100 - 24 .

Discriminant : 74 .

Therefore, Discriminant : 74 .

What is the probability of rolling a number less than 4 on a number cube labeled 1 through 6?
Leya [2.2K]
No matter the number of times you rolled the dice, the probability of getting a number is always 1/6. But here we can choose 4 numbers ( 1 to 4) hence the probability P( 1 or 2 or 3 or 4) = 4/6 2/3  = 0.6667 = 66.67% (A)

What values of x makes the expression (x-6)(x+3) positive?​
Georgia [21]

Answer:

This means that for (x-6)(x+3) to be positive, the value of x has to be greater than 6; x>6

Step-by-step explanation:

Step 1

Given the equation;

(x-6)(x+3)

Step 2

To determine the values of x that make the equation positive, the equation can be expressed as;

(x-6)(x+3)>0

x-6>0/(x+3)

x-6>0

x>0+6

x>6

This means that for (x-6)(x+3) to be positive, the value of x has to be greater than 6; x>6

Consider a situation in which p(x) = and p(y) = . if p(x and y) is = , which best describes the events? they are independent bec
jeka94

Considering the given probabilities, it is found that the correct option about whether the events are independent is given as follows:

p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).

<h3>What are independent events?</h3>

Two events, A and B are independent, if:

P(A \cap B) = P(A)P(B)

Researching this problem on the internet, the probabilities are given as follows:

P(X) = \frac{4}{5}, P(Y) = \frac{1}{4}, P(X \cap Y) = \frac{1}{5}

Hence:

P(X)P(Y) = \frac{4}{5} \times \frac{1}{4} = \frac{1}{5} = P(X \cap Y)

Hence the events are independent and the correct option is given by:

p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).
