Answer:

25 times

Explanation:

Blue Marvels: 3

Red Marvels: 5

Total Marvels: 5 + 3 = 8 marvels

Probability: favorable outcomes/total outcomes

Probability - red marble =  5/8

After Doing 40 times:

= 5/8 × 40

= 25

Answer:

Coordinates of M = (2, -1)

Length of AB = 10 units

Step-by-step explanation:

Coordinates of the midpoint (M) of the distance between A(2, 4) and B(2, -6)

M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})

Let A(2, 4) = (x_1, y_1)

B(2, -6) = (x_2, y_2)

Thus:

M(\frac{2 + 2}{2}, \frac{4 +(-6)}{2})

M(\frac{4}{2}, \frac{-2}{2})

M(2, -1)

Length of AB:

Distance between A(2, 4) and B(2, -6):

AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

A(2, 4) = (x_1, y_1)

B(2, -6) = (x_2, y_2)

AB = \sqrt{(2 - 2)^2 + (-6 - 4)^2}

AB = \sqrt{(0)^2 + (-10)^2}

AB = \sqrt{0 + 100} = \sqrt{100}

AB = 10

Question 5 (2 points) <br> Find x, y, and z.
Verizon [17]

Answer:

Its actually really easy.

Y is = to 76 degree (Vertically Opposite Angle)

The same way x = z (Vertically Opposite Angles)

So as y = 76 and given angle also 76 we'll add them. You should get 152. Now we know x = z. And we also know angles around a point add up to 360. So 360 - 152 gives 208. Since there are two angles we'll divided them by 2. So you now have 104

Given angle : 76

Y : 76

X : 104

Z : 104

4 3/8+ 2 7/12 <br> Alguém sabe a resposta
Nata [24]

Answer:

6 23/24

Step-by-step explanation:

First, find the least common factor of 8 and 12, the denominators.

8 16 24

12 24

24, is now the current denominnator,

8x 3 = 24

Now you go do it to the numerator, 3 x 3 = 9

9/24 + ?

Now, 12 x 2 = 24, do it to the numerator, 7 x 2 = 14

4 9/24 + 2 14/24

Now add the front numbers to make 6, than add the numerators and keep the denominator.

6 23/24, since you can not simplify this fraction, this is the answer.
