Answer:

Options A and B

i.e., A. 4(3 $\sqrt{7x}$ ) and B. $\sqrt{7x}$

Step-by-step explanation:

Like radicals are similar to like terms.

For example,

x, 2x, -10x, $\frac{1}{2} x$ , 7.3x are like terms.

$xy^{2} , -9xy^{2} , 13y^{2} x$ are some more examples of like terms.

Similarly, like radicals are:

$\sqrt{2} , -5\sqrt{2} , 1.1\sqrt{2}$ etc.

Hence, from the given options, like radicals to $3\sqrt{7x}$ are:

A. $4(3\sqrt{7x} )$ and B. $\sqrt{7x}$

Answer: C

Step-by-step explanation:

Rejecting the null hypothesis means we've found a significant difference in the means. That means the probability that we'd see means so far apart by chance is less than our threshold of significance.

Ricardo spends 8/9 hr. reading the paper. He spends 1/4 of the time reading world news and splits the remaining time equally bet

lapo4ka [179]

Total time spent reading is = 8/9 hour

He spends 1/4 of the time reading world news. That is = 1/4 * 8/9 = 2/9 hour

Splits the remaining time equally. Remaining time = 8/9 - 2/9 = 6/9

Splitting it equally = 6/9 divided by 2 = 6/9 * 1/2 = 3/9 = 1/3

Time spent reading comic is = 1/3 hour

I hope this helps.
