Answer:

Salary by day = .01 * 2^(n-1)

where n = # of days so

day 1 = .01 * 2^(1 -1) = .01 * 2^0 = .01

day 2 = .01 * 2^(2 -1) = .01 * 2^1 = .02

day 3 = .01 * 2^(3 -1) = .01 * 2^2 = .04

day 4 = .01 * 2^(4 -1) = .01 * 2^4 = .08

Logan's e-reader sent a notification saying that he has completed 75% of the e-book.

Vika [28.1K]

Answer:

The total number of pages in the e-book is 240.

Step-by-step explanation:

Given:

Logan has completed 75%

Logan has read 180 pages

To Find:

The total number of pages in the e-book= ?

Solution:

Let X be the total number of pages on the e-book

then

=> 75% of X = 180

Now lets find the value of X

X = $\frac{180}{75\%}$

X = $\frac{180}{\frac{75}{100}}$

X = $\frac{180}{0.75}$

X = 240

Elenna [48]

Answer:

C) Neither

Step-by-step explanation:

These two equations are not parallel, because they don't have the same slope. And they're not perpendicular to each other either, because perpendicular lines have negative reciprocals of the slopes. Therefore, the answer is C) Neither.

Based on the information from Harper's Index, 37 out of 100 adult Americans who did not attend college believe in extraterrestri

vazorg [7]

Answer: Yes, this indicate the proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college.

Step-by-step explanation:

Since we have given that

Hypothesis:

$H_0:p_1=p_2\\\\H_a:p_1>p_2$

n₁ = 100

x₁ = 37

So, $p_1=\dfrac{x_1}{n_1}=\dfrac{37}{100}=0.37$

n₂ = 100

x₂ =47

So, $p_2=\dfrac{47}{100}=0.47$

At 0.01 level of significance, z = 2.33

So, test statistic value would be

$z=\dfrac{p_1-p_2}{\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}}\\\\z=\dfrac{0.37-0.47}{\sqrt{\dfrac{0.37\times 0.63}{100}+\dfrac{0.47\times 0.53}{100}}}\\\\z=-1.44$

Since, 2.33>-1.44

Hence, we will reject the null hypothesis.

Therefore, Yes, this indicate the proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college

De un total de 24 niñas 1/4 practican natación, 1/2 juega volibol y el resto no practica ningún deporte. ¿Cuántas niñas no pract

masya89 [10]

Answer:

6 niñas no practican ningún deporte.

Step-by-step explanation:

De un total de 24 niñas, $\frac{1}{4}$ practican natación. Esto se expresa mediante la operación matemática:

$\frac{1}{4} *24$

Para multiplicar una fracción por un número entero, cualquier entero n puede ser escrito como la fracción $\frac{n}{1}$ . Entonces en este caso:

$\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}$

Ahora se multiplican los denominadores para obtener el denominador final y se multiplican los numeradores para obtener el numerador final:

$\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}=\frac{1*24}{4*1}=\frac{24}{4}$

Finalmente, se reduce el resultado hasta llegar a la forma más simple. Para obtener un resultado simplificado, se divide el numerador por el denominador. En este caso, para reducir la fracción $\frac{24}{4}$ , se divide 24 por 4. El resultado obtenido es 6. Esto indica que de un total de 24 niñas, 6 practican natación.

Por otro lado, de un total de 24 niños, $\frac{1}{2}$ juegan voleibol. Esto se expresa mediante la operación matemática:

$\frac{1}{2} *24$

Resolviendo de manera similar a lo previamente calculado, se obtiene:

$\frac{1}{2} *24= 12$

Esto indica que de un total de 24 niñas, 12 practican voleibol.

Por lo que 6 niñas practican natación y 12 voleibol, siento un total de 18 niñas las que practican algún deporte. Por lo que la cantidad de niñas que no practican ningún deporte se calcula mediante:

24 niñas - 18 niñas que practican algún deporte= 6 niñas

6 niñas no practican ningún deporte.

Y = f(x) = 3 Find f(x) when x = 0. Enter the correct answer.

dalvyx [7]

Answer:

Step-by-step explanation:

Because f(x) = 3, any value of x will make f(x) = 3. So when x = 0, f(x) = 3.
