Sorry, mate but it cannot be solved. m is a complicated number like $\sqrt{-1}$

But if you really want the answer, here it is:
m = (5 ± 3 $\sqrt{-7}$ ) / 4

If it helps, can you give me the brainliest answer? I need it...

Thank you very much.

Convert 18 centimeters per second to meters per hour.<br> hint: 1 m = 100 cm

denis-greek [22]

Answer:

The answer to your question is 648 m/h

Step-by-step explanation:

$\frac{18 cm}{s} \frac{1 m}{100 cm} \frac{3600 s}{1 h}$

$\frac{(18)(1)(3600)}{(1)(100)(1)}$

$\frac{64800}{100}$

= 648 m/h

Six - two times twelve plus five

fomenos

Answer:

Ok, so the equation would be 6-2*12+5. The answer to that is -13.

Step-by-Step Explanation:

You would use PEMDAS. First, you multiply 2 and 12 and that's 24. Now your equation is 6-24+5. Then you subtract 6 and 24 and that's -18. Now your equation is -18+5, and the answer to that equation is -13. I hope this helps you!!

xP(x)00.2510.0520.1530.55Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal pl

Nookie1986 [14]

The Solution:

Given:

Required:

Find the standard deviation of the probability distribution.

Step 1:

Find the expected value of the probability distribution.

$E(x)=\mu=\sum_{i\mathop{=}0}^3x_iP_(x_i)$ $\begin{gathered} \mu=(0\times0.25)+(1\times0.05)+(2\times0.15)+(3\times0.55) \\ \\ \mu=0+0.05+0.30+1.65=2.0 \end{gathered}$

Step 2:

Find the standard deviation.

$Standard\text{ Deviation}=\sqrt{\sum_{i\mathop{=}0}^3(x_i-\mu)^2P_(x_i)}$ $=(0-2)^2(0.25)+(1-2)^2(0.05)+(2-2)^2(0.15)+(3-2)^2(0.55)$ $=4(0.25)+1(0.05)+0(0.15)+1(0.55)$ $=1+0.05+0+0.55=1.60$

Thus, the standard deviation is 1.60

Answer:

1.60
