justin has a bag with 12 blue marbles 6 green marbles 8 purple marbles and 4 red marbles if she wants a probability of picking a blue marble to be 50% what should Justin do

Answers

There are many answers to this, but one answer might be to take away 6 of the other colors. This is because if 12 marbles are to equal 50%, we need the other side to have the same amount of marbles as the blue. And since the other color marbles add up to 18 and not 12, we need to take away six of the other colored marbles to make it 12.

Find the gradient of the line segment between the points (-8,6) and (-10,14)

Answers

The required gradient of the line between the points (-8,6) and (-10,14) is -4.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The gradient of the line segment between points (-8,6) and (-10,14) is given as,

The gradient of the line = slope of the line,
m = (y₂ - y₁) / (x₂ - x₁)

Substitute the value in the above equation,
m = 14- 6 / -10 + 8
m = 8 / -2
m = -4

Thus, the required gradient of the line between the points (-8,6) and (-10,14) is -4.

Answer:

-4

Step-by-step explanation:

14 - 6 = 8

-10 - - 8 = - 2

8 / - 2 = - 4

Evaluate 5ny - 2c when n=-1/5, y= 6, and c= -3.

Answers

Answer:

Step-by-step explanation: plug 1/5 in for the "n", plug 6 in for the "y" and plug -3 in for the "c". This gives you 5 x 1/5 which equals 1. So now you have 1 times 6 which equals 6. Lastly you subtract 2(-3) which is -6. This results in 6 - (-6) which equals 12.

The school fair committee needs pizzas for 275 people .each pizza has 8 slices . How many pizzas does the committee need to order so that each person can have one slice ?Write a number sentence for the problem . Use a variable to represent the number of pizzas .

How many pizzas does the committee need to order so that each person can have one slice ? Show your work . Explain your answer .

Answers

You can just divide 275 by 8. You will get a decimal.
275 / 8 = 34.375
Since you can't really have .375 of a pizza, just round it up to 35. It's okay to have some left over.

The answer including a variable is p =275 divided by 8.
