Each time its rolled it has a 1/6 chance of rolling a two. Out of 50, it should come up as 2 about 8.33 percent of the time. That is the theoretical probability. However, it came up as two 10 of the 50 times, or 20 percent. The difference is about 11.67

the scale on a map is stated as 1 : 250000 2 villages are 9 m apart on the map how far from each other are the two villages in k

Sergio039 [100]

Answer:

2,250,000 km

Step-by-step explanation:

From the above question our scale is given as:

1 m : 250000km

We are trying to find the distance between two villages which is 9m apart in kilometers

Hence

1 m : 250000km

= 1 m = 250000km

9m = x km

Cross Multiply

x km = 9 × 250,000km

x km = 2,250,000 km

Which side lengths form a right triangle

aleksandrvk [35]

Answer:

A and C

Step-by-step explanation:

A right triangle consists of two legs and a hypotenuse.
To find hypotenuse, we use The Pythagorean Theorem
The Pythagorean Theorem = ${a}^{2} + {b}^{2} = {c}^{2}$
two legs meet at a 90° angle and the hypotenuse is the longest side

3 - 4 - 5

6 - 8 - 10

7 - 24 - 25

5 - 12 - 13

are some basic right triangle

(about more, look picture)

<em><u>Just use hypotenuse formula :</u></em>

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

Option C is correct

${5}^{2} + { \sqrt{6} }^{2} = { \sqrt{31} }^{2}$

Option A is correct

${5}^{2} + {5}^{2} = { \sqrt{50} }^{2}$

But B isn't correct

Hope this helps ^-^

How many cubes with side lengths of 1/2 cm does it take to fill the prism? Height: 3/2 cm Width:1 cm length: 2 cm

Irina18 [472]

Answer:

Step-by-step explanation:

If we want to cover the base of the prism having dimensions 2 cm × 1 cm with $\frac{1}{2}$ cm length of cube, then there will be (4 × 2) = 8 cubes that can occupy the base.

Width is 1 cm, so there can fit 2 cubes of length $\frac{1}{2}$ cm and length is 2 cm, where 4 cubes of length $\frac{1}{2}$ cm can fit. So, in total (4 × 2) = 8 cubes of $\frac{1}{2}$ cm length.

Now, height of the prism is $\frac{3}{2}$ cm where 3 cubes of length $\frac{1}{2}$ cm can fit.

Therefore, in total there can be (8 × 3) = 24 cubes of $\frac{1}{2}$ cm length. (Answer)
