Answer:

To identify which integer does not belong with the rest, we must first evaluate each.

Step-by-step explanation:

[25.6...] is already evaluated. Therefore, let's move on to Integer b: $\sqrt{x}$ , where is x is 48.

48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3

√48 = $\sqrt{2}$ * 2 * 2 * 2 * 3

We have 1 perfect sqaure: $\sqrt{2}$ * 2

When we multiply, we receive 2.

Therefore, 2 * $\sqrt{2 * 3}$

When -51/2 is relatively prime, we receive -25 1/2

Finally, the last integer is already simplified.

Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.

For all positive integers n, let *n* equal the greatest prime number that is a divisor of n. What does *10*/*12* equal?

artcher [175]

Answer:

5/3

Step-by-step explanation:

The prime factorizations are ...

10 = 2·5

12 = 2·2·3

Then *10* = 5 and *12* = 3, so *10*/*12* = 5/3.

Please help! I attached the question below.

kompoz [17]

Answer:

$\frac{2(c+2)}{c(c-2)}$

Step-by-step explanation:

$\frac{c^{2}-4 }{6c^{4}+15c^{3}}=\frac{(c-2)(c+2)}{c(6c^{3}+15c^{2}) }$

Identity used:

$a^{2}-b^{2}=(a-b)(a+b)$

$\frac{c^{2}-4c+4}{12c^{3}+30c^{2}}=\frac{(c-2)^{2}}{2(6c^{3}+15c^{2}) }$

Now let us divide the modified expressions:

$\frac{(c-2)(c+2)}{c(6c^{3}+15c^{2})}$ ÷ $\frac{(c-2)^2}{2(6c^{3}+15c^{2}) }$

we get:

$\frac{2(c+2)}{c(c-2)}$

A. In the standard normal and t distributions, the 95% confidence multiplier is equal to the ________ 1-sided critical value.

valkas [14]

Answer:

a. 1.645 multiplier = 5% critical value

b. 95

Step-by-step explanation:

Note that in statistical analysis probability principles are often used. The critical value from the critical region indicates whether the statistician should reject or accept the null hypothesis.

Note that the confidence multiplier is a constant that shows the number of standard deviations in a normal curve; the deviation standard implies the measure of difference between the observed value of a variable and some another value.
