If the mDEF=128, determine its supplement and its complement, if it exists

Mathematics
1 answer:
Mrrafil [7]3 years ago
3 0

Answer:

The supplement would be 62,

There is no complement

Step-by-step explanation:

A Supplementary angle equals 180 degrees

A complementary angle equals 90 degrees

Since mDEF= 128, which is greater than 90 degrees there is no complement to it.

To figure out the supplement of DEF you have to subtract 128 from 180.

180 - 128 = 62

Question 3
AveGali [126]

Answer:

750^2

Step-by-step explanation:

backtrack and find the diameter of circle A. A=πr, which means the diamater is about 159 1/11. three times the diameter will give 477 3/11, so the radius is 238 7/11. multiply it to 22/7 (π) then you get 750^2.

A person's home to work commute on a wintery morning involves traveling on Highway A, Highway B, and then Highway C. The person
SVEN [57.7K]

Answer:

Probability = 0.35

Step-by-step explanation:

Given :-

  • Probability (Highway A Icy) = 0.1
  • Probability (Highway B Icy) = 0.15
  • Probability (Highway C icy) = 0.15

So :-

  • Probability (Highway A not icy) = 1 - 0.1 = 0.9
  • Probability (Highway B not icy) = 1 - 0.15 = 0.85
  • Probability (Highway C not icy) = 1 - 0.15 = 0.85

Probability of person not getting to work timely

=  Probability [Even one of the highway A, B or C is icy]

= 1 - Probability [None of Highway A, B, C is icy]

Since these are independent events, So :-

= Prob. [Highway A not icy & Highway B not icy & Highway C not icy]

= 1 - ( 0.9 x 0.85 x 0.85)

= 1 - 0.65

= 0.35

No chi-square The principal in Exercise 7 also
larisa [96]

The random sample of the students is an illustration of sampling

The chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.

<h3>How to determine the reason chi square is not appropriate?</h3>

The dataset is given as:

Monday        34

Tuesday       29

Wednesday   32

Thursday        28

Friday             19

The variable of the above dataset is a not a categorical dataset.

One of the conditions of the chi-square test for goodness of fit test is that the variable under study must be categorical.

Hence, the chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.

Solve for c: c=5 5/6 x 2
Marina86 [1]

Hi there!

c=11 2/3

<u><em>1.Convert 5 5/6 into mixed number:</em></u>

<u><em /></u>5 \frac{5}{6}=\frac{35}{6}<u><em /></u>

<u><em>2.Convert 2 into fraction term:</em></u>

<u><em /></u>2=\frac{2}{1}<u><em /></u>

<u><em>3.Convert both fraction into same denominator:</em></u>

<u><em /></u>\frac{35}{6}=\frac{35}{6}<u><em /></u>

<u><em /></u>\frac{2}{1}=\frac{12}{6}<u><em /></u>

<u><em>4.Multiply the two terms:</em></u>

<u><em /></u>\frac{35}{6}<u><em>·</em></u>\frac{12}{6}=\frac{70}{6}<u><em /></u>

<u><em>5.Simplfly the fraction term:</em></u>

<u><em /></u>\frac{70}{6}=\frac{35}{3}<u><em /></u>

<u><em /></u>\frac{35}{3}=11 \frac{2}{3}<u><em /></u>

Therefore, c=11 2/3.
