xz_007 [3.2K]1 year ago
3 0

Answer: 24 over 2 squared equals 50 minus 6 squared minus 8

56 divided by 8 plus 3 squared equals 2 times 2 cubed

Step-by-step explanation:

24/2^2 = 50-6^2 - 8

24/4 = 50-36-8

6 = 14-8

6=6

39-3*6 = 6*10/4 + 4

39 - 18 = 15 + 4

21 = 19

9^2 - 5 ^ 2 = 4 ^ 2 - 7

81 - 25 = 16 - 7

56 = 9

56/8 + 3^2 = 2 * 2^3

7 + 9 = 2 * 8

16 = 16

Ilya [14]

Answer:

\displaystyle{ \frac{9}{16} \times  \frac{2}{3}  }

\displaystyle{ \frac{9 \times 2}{16 \times 3} }

\displaystyle{ \frac{18}{48} }

\displaystyle{ \frac{ \cancel2 \times  \cancel3 \times 3}{2 \times  \cancel2 \times 2 \times 2 \times  \cancel3} }

\displaystyle{ \frac{3}{2 \times 2 \times 2} }

\displaystyle{ \frac{3}{8} }

Suppose you wish to test if a number cube (die) is loaded or not. If the die is not loaded, the theoretical probabilities for ea
Sonja [21]

Answer:

Goodness of fit

Step-by-step explanation:

Given

The theoretical probabilities

<em>See comment for complete question</em>

<em></em>

Required

The type of test to be use

From the question, we understand that you are to test if the die is loaded or not using the given theoretical probabilities.

This test can be carried out using goodness of fit test because the goodness of fit is basically used to check the possibility of getting the outcome variable from a distribution. In this case, the outcome of the variables are the given theoretical probabilities.

In a nutshell, the goodness fit of test determines if the given data (in this case, the theoretical probabilities) is a reflection of what to expect in the original population.

A car leaves its garage and travels for 30km on a bearing of 145, then 10 km on a bearing of 250 Calculate a) the distance trave
OverLord2011 [107]

The distance travelled from the starting point is 29 km , the bearing is 344 degree

The missing diagram is attached with the answer.

<h3>What is Bearing Angle ?</h3>

It is the horizontal angle between the object and another object.

It is given that the car starts from point travels for 30km on a bearing of 145, then 10 km on a bearing of 250

(a) the distance travelled from the starting point

It can be understood from the diagram that

To determine the distance , b is to determined4

By applying Cosine rule

b² = a² +c²-2ac cos\rm \theta

b² = 10²  +30²  - 2* 30*10 cos75

b² = 100+900 -600* 0.2588

b² = 100-155.2914

b² = 844.7

b = 29 km

Therefore the distance travelled from the starting point is 29 km.

(b) the bearing of the starting point from the car.

To determine the bearing ,

angle C has to be determined

By sine rule

sin C / c = sin B / b

sin C = sin 75 * 30 / 29

sin C = 0.9970

C = sin⁻¹ 0.9970

C = 85.59 degree

angle C = α +70 degree

α  = 15.59 degree

Bearing = 70 + 20 + 9 0 + 90+74 = 244 degree
