A study was produced which involved 800 randomly selected individuals. Each participant was asked to identify whether they were currently employed or not. 583 responded they were employed while 148 responded that they were not employed. Identify the problem with this study.loaded questions

Answer 1

Answer: Given:
800 randomly selected individuals
583 responded they were employed
148 responded they were not employed

583 + 148 = 731
800 - 731 = 69 missing response.

I think that the problem with this study is correlation and causality.

The correlation between two variables does not mean that it is the cause of the other variable. There are still a lot of factors to consider.

When one says he or she is not employed, it may mean that said individual is either a student or business owner.

a scientist had 3/4 of a bottle of a solution. she used 1/6 of the solution in an experiment how much of the bottle did she use? PLS HELP FOR 20 POINTS

Answers

Answer:

To work this out you need to multiply 3/4 by 1/6.

=3/24

=1/8

Step-by-step explanation:

Hope this helps :)

Final answer:

The scientist used 1/8 of the bottle.

Explanation:

To find out how much of the bottle the scientist used, we need to multiply the fraction of the solution used (1/6) by the fraction of the bottle filled with the solution (3/4).

The solution used = (1/6) * (3/4) = 3/24 = 1/8.

Therefore, the scientist used 1/8 of the bottle.

State the x-coordinate of the x-intercept in quadrant II for the function below.f(x)=x^3-x^2-x+1

Answers

The x-coordinate of the x-intercept in quadrant || for the given function is -1.

x = -1.

What are coordinates?

Coordinates are a set of values that helps to show the exact position of a point in the coordinate plane.

We have,

x-intercept in quadrant ||.

f(x) = x³ - x² - x + 1

x-intercept means y = 0 so,

f(x) = y

0 = x³ - x² - x + 1

We see that,

when x = -1 we get,

f(x) = -1 - 1 + 1 + 1 = 0

When x = 1 we get,

f(x) = 1 - 1 - 1 + 1 = 0

But we can not take x = 1 because in quadrant || x is a negative value.

Thus,

The x-coordinate of the x-intercept in quadrant || for the given function is -1.

ANSWER

The x-coordinate of the x-intercept of the function $f(x)=x^3-x^2-x+1$ is $-1$ .

EXPLANATION:

The x-intercept refers to the point where the function meets or cuts the x-axis.

At the x-intercept, $f(x)=0$ .

This means we have to equate the whole function to zero and solve for $x$ .

$x^3-x^2-x+1=0$

According to the rational roots theorem, the possible rational roots of the equation $x^3-x^2-x+1=0$ are $\pm 1$ .

We now plug in these possible rational roots to see which of them are real roots.

$f(1)=1^3-1^2-1+1$

$f(1)=1-1-1+1$

$f(1)=-1+1$

$f(1)=0$

Since $f(1)=0$ , $x=-1$ is a root.

By the factor theorem, $x+1$ is a factor of the function.

We now divide the polynomial function, $x^3-x^2-x+1=0$ by $x+1$ to find the remaining roots.

See long division in diagram.

This means that $f(x)=(x+1)(x^2-2x+1)$ .

$f(x)=(x+1)(x-1)^2$

$\Rightarrow (x+1)(x-1)^2=0$

Hence the roots are $x=1$ or $x=-1$

In the second quadrant the x-coordinate is negative

Therefore, the x-coordinate of the x-intercept of the function $f(x)=x^3-x^2-x+1$ is $-1$ .

Find the radical equivalent of 272/3 and compute it?

Answers

Answer: The radical equivalent of $27^{(2)/(3)}\n$ is 9.

Step-by-step explanation:

Since we have given that

$27^{(2)/(3)}\n$

We need to find the radical equivalent.

so, we will use the "Exponential law":

$(a^m)^{(1)/(n)}=a^{(m)/(n)}$

so, it becomes,

$27^(2)/(3)\n\n=(3^3)^(2)/(3)\n\n=(3^(3)/(3))^2\n\n=3^2\n\n=9$

Hence, The radical equivalent of $27^{(2)/(3)}\n$ is 9.
