Step-by-step explanation:

Your Welcome Plz Mark Brainliest. I got this because the sqaure root of 1/4 is 0.5 which is bewteen 1 and 0 and it is positive and rational! If you are wondering how to get the sqaure root then here is the steps

1. Simple deduction 1/4 in 1 to the power of 2 and 2 to the power of 2

2.We can simplfy this to 1/2 to the power of 2

3. This will equal 1/2 which is also equal to 0.5

Plz condsierdate giving Brainliest Thanks :)

Answer:

Alternate hypothesis

Step-by-step explanation:

We are given the following in the question:

Proportion of internet providing fiber optic internet in the United States

p = 11.3% = 0.113

Claim:

It is claimed by the technology manufacturer that this proportion is different from 45%

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.45\\H_A: p \neq 0.45$

Alternate hypothesis:

The claim is expressed by the alternate hypothesis that the the percentage of fiber optic internet offered in the United States is different from 45%.

Korvikt [17]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

p= amount at any time

then $\frac{dp}{dt}=0.07 p$

$p=p_0 (1+e^{0.07 t) \\\\$

$P_0=\ principle \ amount \\\\ interest \ =p-p_0=p_0e^{0.07t}\\\\ p=y\frac{dy}{dt}=0.07y_0$

at time $= t\ years$

$\frac{dp}{dt}\\\\c_0=\$ \ 20000\ year\\\\p \to p+dp\\\\ dp=0.07p+c_0$

y= amount at any times

$\frac{dy}{dt}=0.07y+c_0\\\\dt= \frac{dy}{c_0+0.07y}$

For point a:

$\frac{dy}{dt}=20000+0.07 y$

For point b:

$\frac{dy}{20000+0.07 y}=dt\\\\\frac{1}{0.07}|n(\frac{0.07y+20000}{20000})=t\\\\\frac{0.07y}{20000}+1=e^{0.07t}\\\\y=7.1428\times 10^4[e^{0.07t} -1]\\\\y=\frac{20000}{0.07}[e^{0.07t}-1]\\\\$

For point c:

$y(30)=827391.75$

Can you solve x 13x + 7 = 5x - 20 A)3(3/8) B)1(5/8) C)1(5/8) D)3(3/8

Dafna1 [17]

Answer:

x = - 3 3/8

Its negative 3 3/8

Step-by-step explanation:

13x + 7 = 5x - 20

Subtract 5x from both sides

8x + 7 = -20

Subtract 7 from both sides

8x = -27

Divide both sides by 8

x = -27/8

x = - 3 3/8
