4 0

Answer:

Step-by-step explanation:

The quadratic formula allows us to solve any quadratic equation that's in the form ax^2 + bx + c = 0.

(The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .)

If you flip 2 coins, what is the probability of getting exactly 2 heads
Ahat [919]

Answer:

This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

Step-by-step explanation:

The probability of getting 2 heads with 2 coins can be broken into 2 steps:

The first coin must show Heads AND

the second coin must show Heads.

p(h,h)= P(H) <----- and means multiply

P(H) x P(H)= 1/2 x 1/2 =1/4

____ [38]

Answer:

Therefore the value of x is 8 unit.

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

angle B = 90°

angle C = 30°

AB = 4

To Find:

AC = Hypotenuse = ?

Solution:

In Right Angle Triangle ABC Sine Identity we have

\sin C = \frac{\textrm{side opposite to angle C}}{Hypotenuse}\\

Substituting the given values we get

\sin 30 = \frac{AB}{AC}

\dfrac{1}{2} =\dfrac{4}{x}\\\\\therefore x=4\times 2=8\\\\\therefore x =8

Therefore the value of x is 8 unit.
