1/3m- 1- 1/2n when m= 21 and n = 12

1 answer:

4 0

With this one, plug in the values with the corresponding letters. 1/3m would be the same as 1/3(21) to get an answer of 7. Then 1/2(12) which is 6. Now the equation is 7-1-6 to get an answer of 0.

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is t

klemol [59]

Answer:

The conclusion about p using an absolute value inequality is

$0.325 < p < 0.375$

Step-by-step explanation:

From the question we are told that

The sample proportion is $\r p = 0.35$

The margin of error is $E = 0.025$

The confidence interval is mathematically represented as

$\r p -E < p < \r p +E$

=> $0.35 - 0.025 < p < 0.35 + 0.025$

=> $0.325 < p < 0.375$

Find the value of x and simplify completely.

jok3333 [9.3K]

Answer:

Given: A right triangle in which an altitude is drawn from the right angle vertex to the hypotenuse.

To find: 'x' the larger leg of triangle

Solution,

Using let rule for similarity in right triangle:

$\frac{leg}{part} = \frac{hypotenuse}{leg} \\ or \: \frac{x}{27} = \frac{3 + 27}{x} \\ or \: x \times x = 27(3 + 27) \\ or \: x \times x = 81 + 729 \\ or \: {x}^{2} = 810 \\ or \: {x}^{2} = 81 \times 10 \\ or \: {x} = \sqrt{81 \times 10} \\ or \: x = \sqrt{81} \times \sqrt{10} \\ or \: x = \sqrt{ {(9)}^{2} } \times \sqrt{10} \\ \: x = 9 \sqrt{10}$

Hope this helps...

Good luck on your assignment..
