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)

Answers
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]
= [tex]\frac{4}{3}(3.14)[/tex]
= 4.187
≈ 4.19 units³

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].
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

What is the estimated proportion of commercials in all one-hour time slots? Round your answer to the nearest thousandth.
Answers
Answer:
120
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. So, then 10 × 12 = 120

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
