Step-by-step explanation:
2nd 3rd and 4th are the expressions
Answer:
Step-by-step explanation:
Adjacent to the undetermined angle is 6, and the hypotenuse has been given. We can conclude, after looking at our SOHCAHTOA, that we will be using cosine(CAH) to solve this problem.
Let the unspecified angle be
(This sign is called theta, which is just a sign for angle)
Lets start!
cos
= adj/hyp
cos
= 6/13
=
(6/13)
= 62.5
= 63

Answer:
x=20
Step-by-step explanation:
By the Triangle Sum Theorem, the angles of a triangle add up to 180. So we can set up the equation like this:
2x-10+70+4x=180
Combine Like terms
6x+60=180
Subtract 60 from both sides
6x=120
Divide by 6 to isolate the variable
x=20

Answer:
The size of the sample is 840.
The probability that the first three letters of the four-letter code are vowels is=\frac{1}{35}=
35
1
Step-by-step explanation:
Th total number of letters given to form code of 4 letters = 7
Since, the order of the letters in the code matters, which means there is no repetition.
The total number of ways to form the code size =7*6*5*4=8407∗6∗5∗4=840
Therefore, The size of the sample is 840.
Since, there are 3 vowels and rest of 4 letters are consonant.
The number of ways to form code such that the first three letters of the four-letter code are vowels =3\times2\times1\times4=243×2×1×4=24
The probability that the first three letters of the four-letter code are vowels is
=\frac{24}{840}=\frac{1}{35}
840
24
=
35
