Answer:

1.733

Step-by-step explanation:

Given ratio ,

=> 3:2

According to the Question ,

=> $ 2.60 / x = 3/2

=> x = $ 2.60 × 2/3

=> x = $ 1.733

Answer:

≈ $1.73

Step-by-step explanation:

[tex]\frac{2.6}{y} :\frac{3}{2}[/tex]

y × 3 = 2 × 2.6

3y = 5.2

3y ÷ 3 = 5.2 ÷ 3

[tex]y=1\frac{11}{15}[/tex]

y = 1.7333333333333

1.7333333333333 rounds to $1.73

Answer:

Step-by-step explanation:

The rhombus has several relevant properties.

The last of these relations can be used to find x:

  7x° = 35°

  x = 35°/7° = 5

The second of the relations can be used to find y:

  3y° = 90°

  y = 90°/3° = 30

The first of the relations can be used to find z:

  10z -8 = 5z +32

  5z = 40 . . . . . . . . . add 8-5z

  z = 40/5 = 8

Answer:

t² - 7 t + 6 = 0; es una ecuación de segundo grado en t. Sus raíces son: t = 6, t = 1; la segunda solución es físicamente imposible. Uno solo de ellos no puede llenar la piscina en menos tiempo que los dos juntos. Por lo tanto uno de ellos demora 6 horas y el otro 6 - 3 = 3 horas.

Solution :

Given the Joint Probability distribution is :

Y|X     0         1           2           3            P(y)

0       k       0.03    0.03      0.03      k+0.09

1      0.01    0.02    0.04      0.04        0.11

2     0.01    0.01     0.05      0.72        0.79

P(x) k+0.02  0.06   0.12      0.79       k+0.99

Since we know,

[tex]$\sum \sum P(x_i,y_j) = 1$[/tex]

⇒ k + 0.99 = 1

⇒ k = 1 - 0.99

⇒ k = 0.01

Therefore, the value of k is 0.01

Answer:

n+6+2n+3+90=180

3n+99=180

3n=81

n=27

33 plus 90+57=180

Answer:

the value of n is 27 degree

Step-by-step explanation:

n+6+2n+3+90=180 degree (being linear pair)

3n+9+90=180

3n=180-99

3n=81

n=81/3

n=27

A linear pair is a pair of adjacent angles formed when two lines intersect.

Answer:

[tex]a_5 = 21[/tex]

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + d(n-1)[/tex]

In which [tex]a_1[/tex] is the first term and d is the common difference.

In this question:

[tex]a_1 = 5, d = 4[/tex]. So

[tex]a_n = a_1 + d(n-1)[/tex]

[tex]a_n = 5 + 4(n-1)[/tex]

Find the value of a_5

[tex]a_n = 5 + 4(n-1)[/tex]

[tex]a_5 = 5 + 4(5-1) = 5 + 16 = 21[/tex]

So

[tex]a_5 = 21[/tex]

The [tex]a_{5}[/tex] term of an arithmetic sequence is 21.

An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant, and this difference is called the common difference.

The nth term of the sequence is given by

[tex]\rm a_{n} =a_{1} + (n-1)d\\[/tex]

[tex]a_{1}[/tex]= the first term of the sequence and d is a common difference.

[tex]\rm a_{1} = 5, d=4\\\rm a_{n} =a_{1} + (n-1)d\\\rm a_{n} = 5 + 4(n-1)\\\rm a_{5} = 5 + 4(5-1)\\\rm a_{5} = 21[/tex]

Therefore, The [tex]a_{5}[/tex] term of an arithmetic sequence is 21.

Like terms are terms that have same variable. For example:

The thing that you need to becareful is about the degree. Even though x² and x both are also x-term, but they are not considered like terms. So basically like terms are terms that have same variable and same degree.

Given the expression below:

[tex] \large{2x + 2y + {x}^{2} - x + {x}^{2} }[/tex]

From the expression:

Arrange in better form for our calculation.

Answer:

r=20

Step-by-step explanation:

since the angle and sum of a straight line is equal to 180, you structure an equation:

180=105+(4r-5)

solve for r

180=100+4r

80=4r

20=r

check answer

4r-5     4(20)-5

80-5

75+105=180

Answer:

m∠LMN = 74°

Step-by-step explanation:

Use the property of central angle formed by the arc,

"Measure of an arc is equal to the measure of the central angle"

m(arc LN) = m∠LMN

74° = m∠LMN

m∠LMN = 74°

Therefore, measure of m∠LMN will be 74°.

b) This probability is not accurate because this experiment must be repeated a large number of times for empirical probabilities should be accurate.

Step-by-step explanation:

On 6 occasions, of which three times the train was late. that means 3 times the train is on time.

Empirical probability = Number of outcomes satisfying event / No.of trails

                                = 3/6 = 0.5.

a) This probability as empirical Probability.

b) This probability is not accurate because this experiment should be repeated a large number of times for empirical probabilities should be accurate.

Answer:

y = (2/3)x + 4 2/3

Step-by-step explanation:

For reference, a linear function has an equation of y = mx + b

The first thing we're going to do is use the slope formula, [tex]\frac{y2-y1}{x2-x1}[/tex] or rise over run. In this case that looks like:

(-2-4) - (8 - -1)

-2 -4 comes out to - 6, and the denominator comes out to 9.

6/9 is equal to 2/3, which is our m or slope value.

Next we want to find the b value, or our y-intercept. To do that we'll plug one of the points into the equation with our new-found slope:

4 = (2/3)-1 +b

4 = -2/3 + b

4 2/3 = b

That means our complete equation is:

y = (2/3)x + 4 2/3

OR

y = (2/3)x + 14/3 (equivalent but an improper fraction rather than a mixed fraction).

Step-by-step explanation:

a)

[tex] \frac{1 + \sin y}{ \cos y} + \frac{ \cos y}{1 + \sin y} = \frac{1 + 2 \sin y + \sin^{2} y + \cos ^{2} y}{ \cos y(1 + \sin y)} [/tex]

[tex] = \frac{2 + 2 \sin y}{ \cos y (1+ \sin y)} = \frac{2}{ \cos y} = 2 \sec y[/tex]

b)

[tex] \frac{ \cot x}{ \tan x + \cot x} = \frac{ \cos x}{ \sin x( \frac{ \sin x}{ \cos x} + \frac{ \cos x}{ \sin x} )} [/tex]

[tex] = \frac{ \cos x}{ \frac{ \sin^{2} }{ \cos x} + \cos x } = \frac{ \cos x}{ \frac{ \sin ^{2} x + \cos^{2} x}{ \cos x} } [/tex]

[tex] = \cos ^{2} x[/tex]

c) Note that cscx = 1/sinx so

[tex] \csc^{2} \theta \tan^{2} \theta - 1= \frac{1}{ \cos^{2} \theta } - 1[/tex]

[tex] = \frac{1 - \cos^{2} \theta }{ \cos \theta} = \frac{ \sin^{2} \theta}{ \cos ^{2} \theta } = \tan^{2} \theta[/tex]

Step-by-step explanation:

A Diginacci sequence is created as follows.

• The first two terms are any positive whole numbers.

• Each of the remaining terms is the sum of the digits of the previous

two terms.

For example, starting with 5 and 8 the Diginacci sequence is

5, 8, 13, 12, 7, 10,. . .

The calculations for this example are

5 + 8 = 13, 8 + 1 + 3 = 12, 1+ 3 +1+ 2 = 7, 1 + 2 + 7 = 10.

a) List the first 26 terms of the Diginacci sequence above.

b) Find, with explanation, two starting terms for a Diginacci sequence

so that its 2021st term is 11.

c) Find, with explanation, a Diginacci sequence that has no term equal

to 11.

d) Find, with explanation, a sequence with two different starting terms

which contains five consecutive terms that are even and not all identical

Both 2 and 3 is correct.
