A pair of dice is rolled. Two dice are rolled

Possible outcomes are

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

So total of 36 outcomes

Question says 'the probability of rolling a sum not less than 3'

we look at the pair that has sum greater than or equal to 3

There is only one pair (1,1) whose sum is 1+1 =2

So we ignore (1,1) pair

Remaining 35 pairs have sum greater than 3

the probability of rolling  = (number of times event occurs)  divide by total number of outcomes

the probability ( rolling a sum not less than 3) = \frac{35}{36}

Rewrite the following equation in standard form.<br><br> y= -2/7x + 5/8
nikitadnepr [17]
The equation in standard form would be,
\frac{2}{7} x + y =  \frac{5}{8}
All you have to do is move -2/7x to the other side.

Hope this helped

Find the solution to the equation below.
Andreyy89

Answer:

B and D

Step-by-step explanation:

The quadratic formula is x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}. Here a=20, b=-26, and c=8.

Substitute and you'll have:

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{26+/-\sqrt{26^2-4(20)(8)} }{2(20)}=\frac{26+/-\sqrt{676-640} }{40)}

\frac{26+/-\sqrt{36} }{40}=\frac{26+/-6 }{40}

This means the solutions are 26 - 6/ 40 and 26 + 6/ 40.

It simplifies to 1/2 and 4/5.

Yakvenalex [24]

Answer:

Step-by-step explanation:

------------

It's a straight line, so you need 1 additional point.

---

Plot (-4,4)

Slope 1/2 --> y increases 2 for each 1 of x increase.

Add 1 to x, and 2 to y ---> (-3,6)
