Help!!!! What’s an appropriate method to solve 9x^2+3x-2=0??

1 answer:

5 0

To solve that use the Quadratic formula.
$ax^{2} + bx + c = 0$
$9 {x}^{2} + 3x - 2 = 0$
Solve using:
$x(1) = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a}$
and
$x(2) = \frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a}$
Answers are
$x(1) = \frac{1}{3} \\ x(2) = - \frac{2}{3}$

X and Y are loss random variables, with X discrete and Y continuous. The joint density function of X and Y is f(x, y) = [(x+1)e-

STALIN [3.7K]

Answer:

The probability that the total loss, X + Y is less than 2 is P=0.235

Step-by-step explanation:

We know the joint density function:

$f(x,y)=\frac{(x+1)e^{-y/2}}{12}$

To find the probability that (X+Y)<2, we can divide this in two steps.

- When X=0, Y should be less than 2. This is P(X=0,Y<2).

- When X=1, Y should be less than 1. This is P(X=1, Y<1).

We can calculate P(X=0,Y<2) as:

$P(X=0,Y$

We can calculate P(X=1,Y<1) as:

$P(X=1,Y$

Then

$P(X+Y$

If a tightrope walker falls, he will land on a safety net. His height h in feet after a fall can be modeled by h(t) = 60 - 16t2,

hjlf

As we know that
h = 60 - 16t^2 
t = sqrt((60 - h)/16) 
= sqrt((60 - 11)/16) 
= 1.75

Pleas help y’all please

Answer:

option 3

Step-by-step explanation:

BODMAS : the expression contains addition and division. So we will do division first and then addition.

$\frac{1}{3} + \frac{5}{4} \div \frac{3}{2}\\\\\frac{1}{3} + (\frac{5}{4} \div \frac{3}{2})\\\\\frac{1}{3} +( \frac{5}{4} \times \frac{2}{3} )\\\\\frac{1}{3} + \frac{5}{6}\\\\\frac{2 + 5}{6} \\\\\frac{7}{6} = 1 \frac{1}{6}$
