Answer:

2/3

Step-by-step explanation:

How many equations here have a slope of 3?

We need to find them and count them.

3y = 9x + 3

1st.  y = 3x + 1  has slope 3

2nd ... x(x+3) = 0  is not a line

3rd.  3x + y = 0    y = -3x

4rth.   x^2 + 3 = 0  is not a straight line

5th   y - 3x = 0  is  y = 3x    yes has slope 3

Only 2 equations have a slope of 3.     2 out of 5 total but...

But there are only 3 equations here that are straight lines

so  2 out of 3

the employees of a company were surveyed on questions regarding their educational background ( college degree) and marital statu
Llana [10]

Number employees N = 600

Then

Probability of Single + College degree = ?

Probability of single S = 100/600 = 1/6

Probability of College graduate G = 400/600 = 2/3

So then probability of both S and G is

Prob Single or Graduate = 1/6 + 2/3 = 1/6 + 4/6 = 5/6

. = 0.833

Then answer is

Probability of Single or Graduate = 5/6= 0.8333

Is also 83.33%

Heidi wants to make some biscuits using this recipe.
Andre45 [30]

The most cookies Heidy can make is 36 cookies.

<h3>How to calculate how many cookies can Heidy make?</h3>

To know how many cookies Heidy can make, you have to take into account the following information:

12 cookies need the following ingredients:

  • 125g butter
  • 200g flour
  • 50g sugar

In the case in which Heidy has more ingredients, we must carry out the following operations:

Divide the quantities, in the reference quantity we have:

  • 500g of butter ÷ 125g of butter = 4
  • 700g flour ÷ 200g flour = 3.5
  • 250g of sugar ÷ 50g of sugar = 5

According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.

So the number of cookies Heidy can make are:

12 × 3.5 = 42

-8 -8x + 10 + 6x = 19
hram777 [196]

Answer:

x = -8.5

Step-by-step explanation:

Let's rearrange the question to find x :)

-8x + 6x + 10 - 8 = 19

-2x + 2 = 19

-2             -2

-2x = 17

/-2      /-2

x = -8.5
