Probability

There are:

5 anthropology students

3 sociology students

4 psychology students

5 + 3 + 4 = 12 students in total

The probability that one randomly selected student is for anthropology is:

p=\frac{5}{12}

Note we have divided the number of favorable cases by the total cases

Write the number from least to greatest 0.6 1/2 2/3 0.39
Masja [62]

Answer:

0.39,\frac{1}{2},0.6,\frac{2}{3}

Step-by-step explanation:

Since \frac{1}{2}=0.5, this would go behind 0.6, and since \frac{2}{3}=0.6\bar{6}, this would go in front of 0.6

Hence, the order of the numbers from least to greatest would be 0.39,\frac{1}{2},0.6,\frac{2}{3}

A map is laid out in the standard (x,y) coordinate plane. How long, in units, is an airplane's path on the map as the airplane f
xeze [42]

Answer:

Distance between the points A and B is 15.52 units.

Step-by-step explanation:

It has been given in the question that an airplane flies along a straight line from City A to City B.

Map has been laid out in the (x, y) coordinate plane and the coordinates of these cities are A(20, 14) and B(5, 10).

Distance between two points A'(x, y) and B'(x', y') is represented by the formula,

d = \sqrt{(x-x')^{2}+(y-y')^{2}}

So we plug in the values of (x, y) and (x', y') in the formula,

d = \sqrt{(20-5)^{2}+(14-10)^{2}}

d = \sqrt{(15)^{2}+(4)^{2}}

d = \sqrt{225+16}

d = 15.52

Therefore, distance between the points A and B is 15.52 units.

A small plane and a large plane are 6.8km from each other, at the same altitude (height). From an observation tower, the two air
Lemur [1.5K]

Answer:

7.9km

Step-by-step explanation:

(a)See attached for the diagram representing this situation.

(b)

In Triangle ABC

\text{Using Law of Sines}\\\dfrac{\sin A}{a}=\dfrac{\sin C}{c} \\\dfrac{\sin A}{5.2}=\dfrac{\sin 58^\circ}{6.8} \\\sin A=5.2 \times \dfrac{\sin 58^\circ}{6.8}\\A=\arcsin (5.2 \times \dfrac{\sin 58^\circ}{6.8})\\A=40.43^\circ

Next, we determine the value of Angle B.

\angle A+\angle B+\angle C=180^\circ\\40.43+58+\angle B=180^\circ\\\angle B=180^\circ-(40.43+58)\\\angle B=81.57^\circ

Finally, we find b.

\text{Using Law of SInes}\\\dfrac{b}{\sin B}=\dfrac{c}{\sin C} \\\dfrac{b}{\sin 81.57^\circ}=\dfrac{6.8}{\sin 58^\circ} \\b=\dfrac{6.8}{\sin 58^\circ} \times \sin 81.57^\circ\\b=7.9km $ (to the nearest tenth of a kilometer)

The distance between the small plane and the observation tower is 7.9km.

What is an expression for the total cost of feeding h horses?
gogolik [260]

Let's say the cost to feed each horse is $5.00.

The expression would be written as:

(5.00)h or simplified as 5h

This is because you are multiplying the cost for feeding each horse by the amount of horses, represented as h.

If you are feeding 6 horses you would substitute the h for 6 giving you the expression:

5(6)

which equals $30 total.

Hope this helps and have a nice day! :)
