The answer is:

3 and 4

Step-by-step explanation:

multiplying 7/10 miles by 3 will give you 21/10 which is 2.1 miles

multiplying 7/10 miles by 4 will give you 28/10 which is 2.8 miles

Answer 2

Answer:

i think is 3 times and 4 times because.....

Step-by-step explanation:

For Tristan to  jog between 2 and 3 miles, the number of times he would have to jog the route that is 7/10 mile must be such that the product of the number of times and 7/10 miles gives a number between 2 and 3.

Considering the options given

A. 2 * 7/10 = 1.4 miles (this is not within the range)

B. 3 * 7/10 = 2.1 miles (this is within the range)

C. 4 * 7/10 = 2.8 miles (this is within the range)

D. 5 * 7/10 = 3.5 miles (this is not within the range)

the polynomial y = x^{5} + x^{3} - x^{2} - 1 factors into (x^{2} + 1) (x^{3} - 1). what is the multiplicity of the root (x^{3} - 1)?

Answers

Answer:

The multiplicity of the root is 1

Step-by-step explanation:

Firstly, we need to understand what multiplicity is

By multiplicity, we simply refer to the number of times we have the certain root repeating itself

From the factorization, each of the given roots were only repeated once

That indicates that the given multiplicity is 1

Answer:

Volume of the given sphere = 4.19 units³

Step-by-step explanation:

Volume of a sphere is given by the expression,

V = [tex]\frac{4}{3}\pi r^{3}[/tex]

Here, r = radius of the sphere

From the picture attached,

Radius of the sphere 'r' = 1 unit

Volume of the given sphere =  [tex]\frac{4}{3}\pi (1)^3[/tex]

                                               = [tex]\frac{4}{3}\pi[/tex]

Answers

Answer:

0.1. B) 50%

0.2 A) Psicología

Step-by-step explanation:

01. Dejemos que 'x' e 'y' representen el porcentaje de boquichicos y carachamas en la piscifactoría, tenemos;

Dado que el 30% de los boquichicos es el 20% del número de carachamas

30% x = 20% y

∴ 0.3 · x = 0.2 · y

Por lo tanto, tenemos;

x / y = 0,2 / 0,3 = 2/3

Por lo tanto, por cada 100% de pescado, tenemos;

x + y = 100%

x = 2/3 · y

2/3 · y + y = 100%

5 · años / 3 = 100

y = 100 × 3/5 = 60%

El porcentaje de carachamas en la finca, y = 60%

∴ x = 100% - y = 100% - 60% = 40%

El porcentaje de boquichicos en la finca, x = 40%

Por lo tanto, tenemos el 80% del pescado en la granja, obtenemos;

Si hay 100 peces en la granja, 80% = 80 peces

Pero el número de los 100 peces que son boquichicos en la granja = 40% × 100 = 40 peces

Por lo tanto, los boquichicos son la mitad del 80% del número de peces o el 50% de los peces en la piscifactoría.

La opción correcta es;

B) 50%

02. Tenemos;

El costo de un libro de psicología> El costo de un libro en inglés

El costo de un libro de matemáticas> El costo de un libro de historia

El costo de un libro de psicología> El costo de un libro de matemáticas

Por lo tanto, tenemos;

El costo de un libro de psicología> El costo de un libro de matemáticas> El costo de un libro de historia

∴ El libro de Psicología es más caro que todos los demás libros y, por tanto, es el libro más caro

La opción correcta es;

A) Psicología

Answers

Answer:

[tex]sin(\theta_1) = \dfrac{\sqrt{357} }{29}[/tex]

Step-by-step explanation:

The parameters of the angle θ₁ are;

The location of θ₁ = Quadrant II

cos(θ₁) = -22/29

We note the following;

1) The sine of an angle in quadrant II is positive

2) The cosine of an angle in quadrant II is negative,

2) The cos of an angle = The adjacent leg length to the reference angle divided by the hypotenuse length of a right triangle

3) With regards to the right triangle for finding cos(θ₁)

The adjacent leg length = -22 (The x-axis is negative in quadrant II)

The hypotenuse length = 29

The negative sign is obtained from the value of cosine in the quadrant

Therefore, by Pythagoras' theorem, for a right triangle, we have;

The opposite leg length to 'θ₁' = √(29² - 22²) = √(357)

[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

Therefore, we have;

[tex]sin(\theta_1) = \dfrac{\sqrt{357} }{29}[/tex].

6y/6 = 6/6
y = 1

Question 4) 3t - 1 = 8
First we need to add 1 to each side.
3t - 1 + 1 = 8 + 1

Step-by-step explanation:

Remember, always round sample size up, regardless of the decimal part. Answer: To find a 95% CI with a margin of error no more than ±3.5 percentage points, where the true population proportion is around 42%, you must survey at least 764 people. 10×764 = 7640; presumably the electorate is larger than that.

With great care he unfolded this, and smoothed it out with both hands on my table. It bore the impression of an ink-smeared hand laid flat on the paper. This touch of his own little daughter had been always on his heart, as he had come year after year to Calcutta to sell his wares in the streets. Tears came to my eyes. I forgot that he was just a Cabuli fruit-seller. But no, what was I more than he? He also was a father. I sent for Mini immediately from the inner apartment. Clad in the red silk of her wedding-day, with the sandal paste on her forehead, and adorned as a young bride, Mini came, and stood bashfully before me. I remembered the day when the Cabuliwallah and my Mini had first met, and I felt sad. When she had gone, Rahmun heaved a deep sigh, and sat down on the floor. The idea had suddenly come to him that his daughter too must have grown in this long time, and that he would have to make friends with her anew. Assuredly he would not find her as he used to know her, and besides, what might not have happened to her in these eight years?6How does the author convey that the Cabuliwallah had not visited his native country for many years?
