Rewrite each expression so that each term is in the form kxn, where k is a real number, x is a positive real number,

Answer:

So the equation in standard form will be $x^{\frac{-1}{3}}$

Step-by-step explanation:

We have given equation $x^{\frac{-2}{3}}\times x^{\frac{1}{3}}$

We have to write this expression in standard form

For writing in standard form first we have to do operation on the expression

We know that there is property of exponent that when two functions are multiplied with each other then there exponent are added

So $x^{\frac{-2}{3}}\times x^{\frac{1}{3}}=x^{\frac{-2}{3}+\frac{1}{3}}=x^{\frac{-1}{3}}$

So the equation in standard form will be $x^{\frac{-1}{3}}$

Answer:

Step-by-step explanation:

The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.

The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.

From the given situation,

news article says that high school students are currently spending an average of 15 hours per week doing homework online. This is the null hypothesis.

H0: µ = 15 hours

You don't think this is an accurate estimate, although you're not sure whether the real value is higher or lower. This is the alternative hypothesis.

Ha : µ ≠ 15 hours

1) Which of the following is NOT the same as 4 : 20 ?*<br> 8:40<br> 6:50<br> 5:25<br> 1:5

adoni [48]

6:50 is the answer! Hope this helps. You can figure this out by crossing out the ones you KNOW are factors of 4 and 20. And 6:50 is NOT a factor of them . Hope this helped!!

Please help with the question.

Answer:

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = x² + 7 ( subtract 7 from both sides )

y - 7 = x² ( take the square root of both sides )

± $\sqrt{y-7}$ = x
