Answer:

n < -9

Step-by-step explanation:

Divide both sides by -4, like so:

-4n > 36

n > -9

However, anytime you multiply/divide the inequality by a negative number, you must flip the sign around, like so:

n < -9

Check that 2b + b and 3b have the same value when b is 1,2, and 3

Misha Larkins [42]

For this case we have the following expressions:

$2b + b\\3b$

For $b = 1:$

$2 (1) + 1 = 2 + 1 = 3\\3 (1) = 3$

For $b = 2:$

$2 (2) + 2 = 4 + 2 = 6\\3 (2) = 6$

For $b = 3$ :

$2 (3) + 3 = 6 + 3 = 9\\3 (3) = 9$

For any number, the expressions will be equivalent because $2b + b = 3b$

ANswer:

$(2b + b)$ and $3b$ have the same value for b = 1,2,3

Tasya [4]

The 6 measurements are 10.1, 10.02, 9.89, 10.05, 10.16, 10.21, and 10.11Mean -10.8333Sample size - 6Standard dev is 0.1Alpha is 1 – 0.90 Z (0.1) = 1.645So the computation would be:Mean ± Z* s/sqrt (n)= 10.0833 ± 1.645*0.1/sqrt(6)= 10.0833± 1.645*0.0408= 10.0833± 0.0672=10.0161, 10.1505 is the interval.90% confident that the iron rod’s true conductivity is between 10.0161 and 10.1504 microsiemens per centimeter.
