Answer: x=  1/4 y = +  7/4

Step-by-step explanation:

Step 1: Add -2y to both sides.

8x + 2y + - 2y = 14 + −2y

8x = −2y + 14

Step 2: Divide both sides by 8.

8x /8 = -2y + 14/8

x=  1/4 y = +  7/4

Answer:

y=(14-8x) divided by 2

Step-by-step explanation:

minus 8x from both side you get

2y=14-8x

then you divide by 2

y=(14-8x) divided by 2

thats the furthest it can be simplified

Whats 126/399 in its simplest form
marusya05 [52]
A common factor of both 126 and 399 is 3 so we can divide both numbers by 3.

126 / 3 = 42
399 / 3 = 133

A common factor for both 42 and 133 is 7 so we can divide both numbers by 7.

42 / 7 = 6
133 / 7 = 19

19 is a prime number so we can't reduce it anymore, therefore 126/399 in its simplest form is 6/19

Use technology and the given confidence level and sample data to find the confidence interval for the population mean mu. Assume
Sphinxa [80]

Answer: (1.55, 6.45)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline\ {x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Significance level : \alpha: 1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

Sample size : n=41

Sample mean : \overline{x}=4.0\text{ kg}

Standard deviation : \sigma=6.1\text{ kg}

Then, 99% confidence interval for population mean will be :_

4\pm\ (2.576)\dfrac{6.1}{\sqrt{41}}\\\\\approx4\pm2.45\\\\=(4-2.45, 4+2.45)=(1.55, 6.45)

Which square number below 100 also prime numbers?
AnnZ [28]
There's no this kind of number because when a number is a square number, it equals its square root multiplies itself, which contradicts with the definition of prime number (<span>A </span>prime number<span> is a natural </span>number <span>greater than </span>1<span> that has no positive divisors other than </span>1<span> and itself)</span>. There's only 1=1×1, but since 1 isn't included in prime number, there's no answer to your question.
