Answer:

look below

Step-by-step explanation:

The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:

P of picking card with star:

25/50=0.5

Card with square:

15/50=3/10=0.3

Card with circle: 10/50=1/5=0.2

We can then put these values into parts a,b,c, and d:

a) 3/10 chance or 30%

b) 1/5 chance or 20%

c) 1/2+1/5=7/10 chance or 70%

d) 1-0.3-0.2=1/2 chance or 50%

Answer:

y = 11x

Step-by-step explanation:

We have two points so we can find the slope

(1,11) and (2,22)

m = (y2-y1)/ (x2-x1)

   = (22-11)/(2-1)

   = 11/1

The slope is 11

We can use the point slope form to get an equation

y-y1 = m(x-x1)

y-11 = 11(x-1)

Distribute the 11

y-11=11x -11

Add 11 to each side

y-11+11 = 11x-11+11

y = 11x

Help me please! <br> I don’t what is the answer?
vovangra [49]

Answer:

  see below

Step-by-step explanation:

In order to use ASA congruence, you need to show congruence of angles on either side of a congruent segment. (Angle - Side - Angle) Considering the left side of the figure, you have given that ∠B is congruent to its counterpart, side BC is congruent to its counterpart. So, you need to show the angle at C is congruent to its counterpart. That is, you must show ...

  ∠BCA ≅ ∠DCE

Write two different ways to decompose 6/10 into a sum
Likurg_2 [28]
You could do
3/10 + 3/10
1/5 + 2/5
1/10+1/10+1/10+1/10+1/10+1/10
Hope this helps!!

Select all of the following that are ordered pairs of the given function.
mamaluj [8]
The answers are: (-1, 5), (0, 3), (2, -1)


F(x) = 3 - 2x can be expressed as y = 3 - 2x.
Now, let's substitute points from each choice to see which one is true.

1. <span>(-2, -1)
    x = -2, y = -1
    </span>y = 3 - 2x
    -1 = 3 - 2 * (-2)
    -1 = 3 - (-4)
    -1 = 3 + 4
    -1 ≠ 7  - not correct

2. (-1, 5)
    x = -1, y = 5
    y = 3 - 2x
    5 = 3 - 2 * (-1)
    5 = 3 - (-2)
    5 = 3 + 2
    5 = 5   - correct


3. (0, 3)
    x = 0, y = 3
    y = 3 - 2x
    3 = 3 - 2 * 0
    3 = 3 - 0
    3 = 3   - correct

4. (1, 0)
    x = 1, y = 0
    y = 3 - 2x
    0 = 3 - 2 * 1
    0 = 3 - 2
    0 = 1   - not correct

5. (2, -1)
    x = 2, y = -1
    y = 3 - 2x
    -1 = 3 - 2 * 2
    -1 = 3 - 4
    -1 = -1    - correct
