When you have a problem like this, all you have to do is remember that a minus multiplied by a minus is a positive and a minus multiplied by a positive is negative. Since there are five minus signs, the answer is -p.

It is -p... think about it.... two negative signs equal a positive sign, if there are an odd number of negative sign's the real answer is -p, and if there is an even amount, it means it is positive p. In your situation, there are 5 negative signs, so since 5 is an odd number, the p has to be negative.

Mashutka [201]

Answer: 2.71

Step-by-step explanation:

We know that the formula to calculate the standard error is given by :-

S.E.=\dfrac{\sigma}{\sqrt{n}}, where \sigma is the standard deviation and 'n' is the sample size.

Given : Standard deviation : \sigma=\$9

Sample size : n=11

Then , the standard error of the mean is given by :-

S.E.=\dfrac{9}{\sqrt{11}}=2.7136021012\approx2.71

Hence, the standard error of the mean = 2.71

What is the solution of √1-3x=x+3
SOVA2 [1]

Answer:

x = -1

Step-by-step explanation:

\sqrt{1-3x}=x+3\\\\1-3x=x^2+6x+9 \qquad\text{square both sides}\\\\x^2+9x+8=0 \qquad\text{put in standard form}\\\\(x+8)(x+1)=0 \qquad\text{factor}\\\\\left \{ {{x=-8} \atop {x=-1}} \right. \qquad\text{values that make the factors zero}

Only the solution x = -1 will work for this equation. The other solution is extraneous.
