Answer:

There are 1.25 days in 30 hours or 1 1/4 days in 30 hours

Step-by-step explanation:

As we know one day is 24 hours. So if we divide 30 hours by 24 hours (or one whole day) then we get 1.25 days or also known as 1 1/4 days

irga5000 [103]

Answer:

The kind of error the researcher has done is a;

Type I error

Step-by-step explanation:

When carrying out hypothesis testing in statistical analysis, a type I error is the type of error said to have occurred when a null hypothesis that is true or correct is rejected which is a false positive conclusion

Given that that sugar box manufacturing company makes the boxes to be 100 g accurately, and that the researcher makes non-random or randomly selects packets which are not filled, the mean of the filled packets is expected to be 100 g making the conclusion for rejection of the null hypothesis a false positive rejection

which of the following are among the five basic postulates of euclidean geometry? check all that apply
MAVERICK [17]
The five essential hypothesizes of Geometry, additionally alluded to as Euclid's proposes are the accompanying: 
1.) A straight line section can be drawn joining any two focuses. 
2.) Any straight line portion can be expanded uncertainly in a straight line. 
3.) Given any straight line fragment, a circle can be drawn having the portion as a span and one endpoint as the inside. 
4.) All correct points are harmonious. 
5.) If two lines are drawn which meet a third such that the total of the internal points on one side is under two right edges (or 180 degrees), then the two lines unavoidably should converge each other on that side if reached out sufficiently far.

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d, from
kifflom [539]

Answer:

The jetski is 2.28 dB loud when the person is 41 feet away.

Step-by-step explanation:

Loudness (L) ∝ 1 / Distance² (d²)

Introduce a constant 'K'

L = K (1/d²)

L = K/d²

K = Ld²

Find the K from a previously known information: If a person 8 feet from a jetski hears 60 decibels loud

∴ d = 8 ft , L = 60 db

K = 60(8²) = <em>3840</em>

How loud is the jetski when the person is 41 feet away?

Distance is now 41 ft

since: L = K/d²

∴ L = 3840 / 41²

L = 3840 / 1681

L = 2.28 db
