Answer:

3rd answer

Step-by-step explanation:

Two dice with #s 1-6

To roll a sum of 7, the 2 numbers have to add up to 7.

First die                Second die

1                              6

2                              5

3                              4

4                               3

5                               2

6                               1

Each of those combinations adds up to 7. There are 6 of them. The total number of possibilities of rolls is 6 x 6 = 36.

Probability is favorable outcomes / total outcomes, so it's 6/36 = 1/6

<span>1. Make y the subject 
a) 4y=12x+18
y = 3x + 4.5

b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3

2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)

slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1

equation
y = 2.5x + 1


b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)

</span>y= 1/2X + 7
slope = 1/2

slope of line perpendicular = -2

passing through point (3,9)

y = mx + b
9 = -2 (3) + b
b = 15

equation

y = -2x + 15

mixas84 [53]

Kevin will be left with 2 ounces of mixed nuts in the can

Step-by-step explanation:

Given

Total nuts = 16 ounces

As Kevin gave 1/2 of the nuts to his sister, he will be left with

= \frac{1}{2} * 16\\= 8

He is left with 8 ounces of mixed nuts

The he eats 3/4 of the remaining

= \frac{3}{4} * 8 \\= 6\ ounces

so he is left with 8 - 6 = 2 ounces of mixed nuts

Hence

Kevin will be left with 2 ounces of mixed nuts in the can
