A single die is rolled twice. Find the probability of rolling an oddnumber the first time and a number greater than 2 the second

harkovskaia [24]

Answer:

1/3.

Step-by-step explanation:

The 2 events are independent so we multiply the 2 probabilities.

Prob(rolling an odd number) = 3/6 = 1/2.

Prob(rolling a number greater than 2) = 4/6 = 2/3.

The required probability = 1/2 * 2/3

= 2/6

= 1/3.

Please please help me out

Answer: y = 3x + 1

<u>Step-by-step explanation:</u>

The equation is in Slope-Intercept format: y = mx + b where

m is the slope <em>(difference in y's over difference in x's)</em>
b is the y-intercept <em>(value of y when x = 0)</em>

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\text{Let }(x_1,y_1)=(0,1)\quad \text{and}\quad \text{let }(x_2, y_2)=(1,4)\quad then\\\\m=\dfrac{4-1}{1-0}=\dfrac{3}{1}=3$

b = 1 <em>refer to the table that shows y = 1 when x = 0</em>

Now input m = 3 and b = 1 into the Slope-Intercept formula:

y = 3x + 1

Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are in

dem82 [27]

There is no b unfortunately

Find inverse of x+a

x+a=y

interchAnge

y+a=x
y=x-a

Inverse is

f^{-1}x=x-a

Now

x-a=cx-d
x-cx=a-d
x(1-c)=a-d
x=a-d/1-c

So

You can have any number according to this but

c must not be 1
a and d must not be equal .
All three should belongs to integers set

Note:-

As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also

Which of the following inequalities is equivalent to 3-(w+2)>4+2w

Kay [80]

$3 - w - 2 > 4 + 2w \\ - w - 2w > 4 + 2 - 3 \\ - 3w > 6 - 3 \\ \frac{ - 3w}{ - 3} > \frac{3}{ - 3} \\ w < - 1$
The sign at the end changes because both sides of the equation are being divided by a negative number.
