Answer:

sove the equation and you'll get 20

Answer:

See below.

Step-by-step explanation:

To prove these expressions are equivalent, we need to set the two expressions equal to each other in an equation and substitute 3 for g.

15(3) - 2(2(3) + 6) = 11(3) - 12

15(3) - 2(6 + 6) = 11(3) - 12

15(3) - 2(12) = 11(3) - 12

45 - 24 = 33 - 12

21 = 21

Using proportions, it is found that the expected value of the student's score on the test is of 3.4 points.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, there are four multiple choice questions, with five options, worth 3 points each, hence the expected score for the multiple choice questions is given by:

Em(X) = 4 x 1/5 x 3 = 12/5 = 2.4.

There are also two true-false questions(two options), worth 1 points, hence the expected score for the two true-false questions is given by:

Etf(X) = 2 x 1/2 x 1 = 1.

Then, the total expected score is given by:

E(X) = Em(X) + Etf(X) = 2.4 + 1 = 3.4.

Answer:

∠CAD = 44⁰

∠ACD = 44⁰

∠ACB =  136⁰

∠ABC = 22⁰

Step-by-step explanation:

To calculate m∠CAD;

Line AD = Line DC,

thus ∠CAD = ∠ACD = ¹/₂(180 - 92°) [sum of angles in a triangle.]

       ∠CAD =  ¹/₂ x 88 = 44⁰

Also, ∠ACD = 44⁰

To calculate  m∠ACB;

∠ACB = 180 - ∠ACD [Sum of angles on a straight line]

∠ACB = 180 - 44

∠ACB =  136⁰

To calculate m∠ABC;

Line CB = Line CA

Thus, ∠ABC = ∠CAB = ¹/₂(180 - ∠ACB) [sum of angles in a triangle.]

∠ABC =  ¹/₂(180 - 136)

∠ABC =  ¹/₂ x 44

∠ABC = 22⁰

Answer:

19.7%

Step-by-step explanation:

Given that,

In 2000, the world population was 6.1 billion.

In 2015, the world population was 7.3 billion.

We need to find the percentage increase in population. The percent increase in this case is given by :

[tex]\%=\dfrac{7.3-6.1}{6.1}\times 100\\\\=19.67\%\\\\=19.7\%[/tex]

So, the increase in population is 19.7%.

Answer:

7/9 < 5/6

Step-by-step explanation:

The denominator is the common factor of the denominators

That is 54

So we have

7/9 * 6/6 = 42/54

5/6 * 9/9 = 45/54

So, the relation we have is that;

7/9 < 5/6

Answer:

The possible values for ∠V is 81.2° and 98.8°

Step-by-step explanation:

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.

We solve the above question using Sine rule

Sine rule

= u/sin U = v/sin V

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°

Hence:

7.6/sin 68° = 8.1/sin V

Cross Multiply

7.6 × sin V = sin 68° × 8.1

sin V = sin 68° × 8.1/7.6

V = arc sin ( sin 68° × 8.1/7.6)

V = arc sin (0.99)

V = 81.18°

Another value for V = 180° - 81.18°

= 98.82°

Therefore, the possible values for ∠V approximately to the nearest tenth of a degree is 81.2° and 98.8°
