my class collected 389 milk jugs. We used 40 jugs. We gave 30 milk to the first graders. how many milk jugs did we have?

1 answer:

8 0

We will just do the following steps:-

389 - 40 = 349
349 - 30 = 319

So, in the end your class had 319 milk jugs left.

Hope I helped ya!!

Answer:

48%

Step-by-step explanation:

The conditional probability definition applies.

P(med | cold) = P(med & cold) / P(cold)

The probabilities are the table numbers divided by the total of all numbers in the table (100). Since that dividend is the same for all, we can basically ignore it and just use the table numbers.

P(med | cold) = (12)/(8+12+5) = 12/25 = 48/100

P(med | cold) = 48%

You need to expand the brackets on both sides and then you can break it down

2x-4/5=4<br> plsss answer quick

nikdorinn [45]

Answer:

Step-by-step explanation:

$\frac{2x - 4}{5} =4$

First of all multiply through by 5 to eliminate the fraction

That's

$5 \times \frac{2x - 4}{5} = 4 \times 5 \\ 2x - 4 = 20$

Next using the addition property add 4 to both sides of the equation

We have

$2x - 4 + 4 = 20 + 4 \\ 2x = 24$

<u>Divide both sides by 2</u>

$\frac{2x}{2} = \frac{24}{2}$

We have the final answer as

Hope this helps you

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?

cupoosta [38]

Answer:

$\displaystyle y=-\frac{1}{2}x+1$

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Two points are given: (-6,4) and (-2,2). Calculating the slope:

$\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}$

The equation of the line is, so far:

$\displaystyle y=-\frac{1}{2}x+b$

To calculate the value of b, we use any of the given points, for example (-6,4):

$\displaystyle 4=-\frac{1}{2}(-6)+b$

$\displaystyle 4=3+b$

Solving:

b = 1

The equation of the line is:

$\boxed{\displaystyle y=-\frac{1}{2}x+1}$

We can see none of the choices is correct.
