Answer:7

Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7

Find the difference <br><br><br> 15 - (-15)
Yuki888 [10]

Answer:

30

Step-by-step explanation:

Note that, when two negative signs are directly next to each other, they mean addition. Note the rule:

A positive sign & A positive sign = Positive number.

A positive sign & A negative sign = Negative number.

A negative sign & A negative sign = Positive number.

In this case:

- (-15) = + 15

Simplify. Combine like terms:

15 + 15 = 30

30 is your answer.

The null and alternative hypotheses are given. Determine whether the hypothesis test is​ left-tailed, right-tailed, or​ two-tail
WINSTONCH [101]

Answer:    Two-tailed test.

Population mean is the parameter which is tested.

Step-by-step explanation:

Given :   H_0: \mu=105

H_1:\mu\neq105

We know that , the alternative hypothesis (H_1) indicates kind of the hypothesis test we need to perform whether ​left-tailed, right-tailed, or​ two-tailed.

Here, the alternative hypothesis (H_1) is two-tailed, so the hypothesis test is a two-tailed test.

Also, the parameter present in the hypothesis is \mu which is a symbol to represent the population mean.

Thus , Population mean is the parameter which is tested.

How can undefinable terms be used to create precise mathematical definitions?
chubhunter [2.5K]

Answer:

This is done by stating descriptions of these terms.

Step-by-step explanation:

Undefinable terms are terms with no formal definitions. Formal definitions are obtained when specific words are used to define a term. In mathematics, specifically, Geometry words like line, point, and plane have no definite definition, So descriptions are used to identify them.

For example, in describing a point, we note that a point has no dimensions, it is usually denoted with a capital letter, and it indicates a position. Also in a coordinate plane, it is denoted with descriptions such as  (u,v). Corresponding descriptions are given of other undefinable terms.
