Answer:

1/2

Step-by-step explanation:

Well, First let us find the amount of numbers in a die greater than 3.

Remember greater than 3 does not include 3.

We have 3 numbers, 4,5,6 that are greater than 3.

The probabilty of getting a rolling a number greater than 3 is 3/6.

The probability of the coin landing on heads is 1/2.

BUT, the problem is only requiring for you to find the probabilty of rolling a dice greater than 3. (key words)

Which is 3/6 or simplified to 1/2.

Find the equation of the line that contains the point (-1, -4) and is parallel to the line 6x+7y=13 . Write the equation in slo

sineoko [7]

Answer: $y=-\dfrac67x-\dfrac{34}{7}$

Step-by-step explanation:

Slope-intercept form: y=mx+c (i) , of linear equations, m= slope and c= y-intercept of the line.

6x+7y=13in slope intercept form would be :

$7y=13-6x\\\\\Rightarrow\ y=\dfrac{-6}{7}x+\dfrac{13}{7}$

Comparing to (i) , $m = \dfrac{-6}{7}$

Slope of parallel lines are equal.

So, slope of required line = $m = \dfrac{-6}{7}$

Equation of line with slope m and passes through point : $(y-b)=m(x-a)$

So, equation of required line:

$(y-(-4))=\dfrac{-6}{7}(x-(-1))\\\\\Rightarrow\ (y+4)=\dfrac{-6}{7}(x+1)\\\\\Rightarrow\ y+4=\dfrac{-6}{7}x-\dfrac{6}{7}\\\\\Rightarrow\ y=-\dfrac67x-\dfrac{6}{7}-4\\\\\Rightarrow\ y=-\dfrac67x-\dfrac{34}{7}$
