Oak grove and salem are 87 mi from each other. How far apart would the cities be on a map that has a scale of 5in: 29mi

1 answer:

7 0

Ratio and prooprtion

scale:actualdistance=5in:29mi
so
5:29=?:87
5/29=?/87
times both sides by 87
435/29=?
15=?

they would be 15in apart

Answer: Type I error

Step-by-step explanation:

A type 1 error is also referred to as the false positive and it is when a true null hypothesis is incorrectly rejected by the researcher.

On the other hand, type II error which is also refered to as the false-negative is when a null hypothesis which is false is failed to be rejected by the researcher but rather accepted.

Based on the information given in the question, since the data leads to the rejection of the null hypothesis such was later found out to be true, then a type I error has occured.

The equation $x^2-9y^2=900$ <span>defines a hyperbolic cylinder.
</span>
1. Divide the equation $x^2-9y^2=900$ by 900:
$\dfrac{x^2}{900} - \dfrac{y^2}{100} =1$ .
This is the equation of conic section when z=0 (or z=const) and that is hyperbola equation.

2. To find the domain and the range you should express y:
$\dfrac{y^2}{100} =\dfrac{x^2}{900} - 1 \\ \\ y^2= \dfrac{x^2}{9} -100 \\ \\ y=\pm \sqrt{\dfrac{x^2}{9} -100}$ .
Since you have square root,
$\dfrac{x^2}{9} -100\ge 0 \\ x^2-900\ge 0 \\ (x-30)(x+30)\ge 0 \\ x\in(-\infty,-30)\cup (30,\infty)$ . This is the domain, the range is $y\in (-\infty,\infty)$ .
