Answer 1

Answer: find tripples

∛(x^3m)=(∛x^3)(∛m)=x∛m

so find tripples

3.
108=2*2*3*3*3
the only tripple is the 3 so tht goes out and the 2*2=4 stas inside
3∛4

B

4. 250=2*5*5*5
the tripple is 5
5∛2
A

5. ∛-375=(∛-1)(∛375)=(-1)(∛(3*5*5*5))=(-1)(5∛3)=-5∛3

A biased sample is one in which every member of the group has an equal chance of being chosen. True or false?

Answers

This statement is false, in a biased sample every member does not have an equal chance of getting selected.

What is a biased sample?

If some individuals or groups from the population are not represented in the sample, the sample is biased.

Example of a biased sample:

The graph presented in the figure below, represents the drug usage by school students but this is a biased data because it does not include the students who have already passed out from the school or the students who were studying from home, as this data is not the complete data hence it is an example of a biased sample.

45/4 simplified what is the answer

Answers

When you're simplifying mixed fractions, the best thing to do is to divide the numerator (45) by the denominator (4).
45/4= 11.25= 11 and 1 remaining.
This can then be converted to a mixed number, as 11 1/4

For which value(s) of x will the rational expression below be undefined?Check all that apply.
(x-3)(x+6)
x + 7

Answers

Question:

For which value(s) of x will the rational expression below be undefined? Check all that apply.

(x-3)(x+6)/x+7

Answer:

For x = -7 the rational expression is undefined

Solution:

Given rational expression is:

$((x-3)(x+6))/((x+7))$

We have to find the value of x for which the rational expression becomes undefined

A rational expression is undefined when the denominator is equal to zero

Here, the denominator becomes zero when x = -7

Substitute x = -7 in given

$((-7-3)(-7+6))/((-7+7)) = (-10 * -1)/(0) = (10)/(0)$

Thus for x = -7 the rational expression is undefined
