Answer:
x=60
Step-by-step explanation:
here DOB and AOC are vertically opposite angles and the values of them are equal. so lets take the two angles as y.
x+DOB is 90(because EOA is 90 and the sum of angles in a straight line is 180), DOB is y and can write a equation as x+y=90
and 30+2x+y = 180 ,
2x+y=150, (180-30)
then two equations can be made.
x+y=90
2x+y=150
simplifying these two simultaneous equations
can get x as 60. and 2x is 120.
The value of x is 60°
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Here, DOB and AOC have equal values and are at vertically opposed angles. Let's use y to represent the two angles.
Since EOA is 90 and the total of the angles in a straight line is 180, x+DOB equals 90 and can be written as x+y=90.
And 30 + 2x + y = 180 ,
⇒ 2x+y = 180-30
⇒ 2x + y = 150,
After which two equations can be created.
⇒ x+y=90
⇒ 2x+y=150
We have the two simultaneous equations made simpler.
We can get x as 60. and 2x as 120.
Thus, the value of x is 60°

-4x-7+7x-3 simplify
Answer:
3x - 10
Step-by-step explanation:
first set up the like variables next to each other
-4x + 7x - 7 - 3
Then, combine like variables
-4x + 7x = 3x
-7 - 3 = -10
The answer is:
3x - 10
Answer: 3x - 10
Step-by-step explanation:
To simplify you need to combine all like terms, and the only terms here are x terms and number ones, so you would combine those to have

There are n applicants for the director of computing. The applicants are interviewed independently by each member of the three-person search committee and ranked from 1 to n. A candidate will be hired if he or she is ranked first by at least two of the three interviewers. Find the probability that a candidate will be accepted if the members of the committee really have no ability at all to judge the candidates and just rank the candidates randomly. In particular, compare this probability for the case of three candidates and the case of ten candidates.
Answer:
for n = 3
[tex]Z(3) = 0.26[/tex]
for n = 10
[tex]Z(3) = 0.028[/tex]
Step-by-step explanation:
from the question we are that
The number of applicant is n
The number of people on the committee is [tex]N = 3[/tex]
Generally given that the applicant ranking is random the probability of a candidate being accepted is mathematically represented as
[tex]Z(n) = N * \frac{1}{n} * \frac{1}{n} * \frac{n-1}{n} + \frac{1}{n} * \frac{1}{n} * \frac{1}{n}[/tex]
Now for n = 3
[tex]Z(3) = 3 * \frac{1}{3} * \frac{1}{3} * \frac{3-1}{3} + \frac{1}{3} * \frac{1}{3} * \frac{1}{3}[/tex]
[tex]Z(3) = 0.26[/tex]
Now for n = 10
[tex]Z(3) = 3 * \frac{1}{10} * \frac{1}{10} * \frac{10-1}{10} + \frac{1}{10} * \frac{1}{10} * \frac{1}{10}[/tex]
[tex]Z(3) = 0.028[/tex]

Determine the remaining sides and angles of the triangle ABC.
A. 18.95 degree.
B. 0.56 degree.
C. 17.83 m.
Answer:
Angle C ∠C = 160.49°
side b = 0.522 m
side a = 17.34 m
Step-by-step explanation:
Given that;
In a Δ ABC,
∠A = 18.95°
∠B = 0.56°
∠C = ???
side A = ???
side B = ???
side C = 17.83 m
We are to determine the unknown missing sides and the angle.
We know that, the sum of angles in a triangle = 180°
∴
∠A + ∠B + ∠C = 180°
18.95° + 0.56° + ∠C = 180°
∠C = 180° - 18.95° - 0.56°
∠C = 160.49°
Using sine rule to determine the unknown sides. The sine rule can be expressed as:
[tex]\mathtt{\dfrac{sin \ A}{a} = \dfrac{sin \ B}{b} = \dfrac{sin \ C}{c} }[/tex]
To determine side b, we have:
[tex]\mathtt{ \dfrac{sin \ B}{b} = \dfrac{sin \ C}{c} }[/tex]
[tex]\mathtt{ \dfrac{sin \ 0.56^0}{b} = \dfrac{sin \ 160.49}{17.83} }[/tex]
[tex]\mathtt{ b (sin \ 160.49) = 17.83 (sin \ 0.56)}[/tex]
[tex]\mathtt{ b = \dfrac{17.83 (sin \ 0.56)}{(sin \ 160.49)}}[/tex]
[tex]\mathtt{ b = \dfrac{17.83 \times 0.0097737}{0.33397}}[/tex]
[tex]\mathtt{ b = \dfrac{0.174265071}{0.33397}}[/tex]
b = 0.522 m
For side a, we have
[tex]\mathtt{\dfrac{sin \ A}{a} = \dfrac{sin \ B}{b} }[/tex]
[tex]\mathtt{\dfrac{sin \ 18.95}{a} = \dfrac{sin \ 0.56}{0.522} }[/tex]
[tex]\mathtt{a \times sin \ 0.56 = 0.522 (sin \ 18.95)}[/tex]
[tex]\mathtt{a = \dfrac{0.522 (sin \ 18.95)}{ sin \ 0.56}}[/tex]
[tex]\mathtt{a = \dfrac{0.522\times 0.3247 }{ 0.0097737}}[/tex]
a = 17.34 m

Explanation:
Apply Exponent Rule: [tex]\bold{\:a^{-b}=\frac{1}{a^b}}[/tex]
[tex]\bold{3^{-5}: \ \frac{1}{3^5} }[/tex]
The equivalent expression for [tex]3^{-5[/tex] using exponent is [tex]\( \dfrac{1}{3^5} \)[/tex].
Explanation:
When we have a negative exponent, it indicates the reciprocal of the base raised to the positive exponent.
In this case, [tex]3^{-5[/tex] means the reciprocal of [tex]3^5[/tex].
To compute [tex]\( 3^5 \)[/tex] raise 3 to the power of 5, which gives us
[tex]\( 3^5 = 3 \times 3 \times 3 \times 3 \times 3 = 243 \)[/tex]
Now, to get the reciprocal of 243,
simply take [tex]\( \dfrac{1}{243} \)[/tex], which is the same as [tex]\( \dfrac{1}{3^5} \)[/tex].
So, [tex]\( 3^{-5} = \dfrac{1}{3^5} = \dfrac{1}{243} \)[/tex].

Answer: B.

An identification code is to consist of 4 letters followed by 2 digits. Determine the following
a) How many different codes are possible if repetition of letters is permitted, repetition of numbers is not permitted, and the first three entries must all be the same letter
b) How many different codes are possible if the first letter must be an A, B, C, or D and repetition is not permitted?
explanation
Counting Possibilities with Repetition or No Repetition:
Counting the number of possibilities in a given situation can vary quite a bit depending on whether repetition is allowed or not. For example, if trying to find how many 6 letter passwords can be made with 10 letter choices, if the letters are allowed to be repeated then there are 10 choices for each letter in the password - resulting in... 10 x 10 x 10 x 10 x 10 x 10 = 10^6 =1,000,000 possible passwords.
However, if repetition of letters is not allowed, then there are 10 choices for the first letter, but only 9 for the second, 8 for the third, and so on. This results in only 10 x 9 x 8 x 7 x 6 x 5 = 151,200
Answer :
There are 26 letters to choose from and 10 digits (0 through 9).
(a) If the first three entries must all be the same letter, then there are 26 choices for the first entry, but only one choice for the second and third entries. The fourth entry can then be any letter, so there are 26 possible choices for the fourth entry. The fifth and sixth entry must be digits, but repetition of numbers are not permitted. So the fifth entry has 10 choices and the sixth entry only has 9 choices. This is a total of 26 x 1 x 1 x 26 x 10 x 9= 60,840
b) If the first letter must be one of A, B, C, or D, then there are 4 choices for the first entry. No repetition is allowed, so the second entry must be chosen out of the 25 remaining letters, and similarly the third and fourth entry will have 24 and 23 choices each. The fifth and sixth entry must be digits, but repetition of numbers are not permitted. So the fifth entry has 10 choices and the sixth entry only has 9 choices. 4 x 25 x 24 x 23 x 10 x 9=4,968,000 different codes

Step-by-step explanation:
We have the graph of f(x).
In order to find f(0), we simply need to find the y-coordinate of the coordinate when x is 0.
From the graph, we can see that there is a point at (0,1).
In other words, when x is 0, f(x) is 1.
Therefore:

Answer:
Implicit function
[tex]\frac{d y}{d x} = \frac{-1}{2y}[/tex]
Step-by-step explanation:
Explanation:-
Given y² + x - 3=0 ...(i)
Differentiating equation (i) with respective to 'x', we get
[tex]2 y \frac{d y}{d x} +1 = 0[/tex]
⇒ [tex]2 y \frac{d y}{d x} = -1[/tex]
⇒ [tex]\frac{d y}{d x} = \frac{-1}{2y}[/tex]

Answer:
[tex]\huge\boxed{ \text{(A)}\ \ \frac{1}{10}, -\frac{1}{10}}[/tex]
Step-by-step explanation:
We can simplify this expression down so that we have x isolated on one side of the equation.
So we can take the square root of both sides.
[tex]x = \sqrt{\frac{1}{100}}[/tex]
The square root of [tex]\frac{1}{100}[/tex] will be the number that, when multiplied by itself, will get us [tex]\frac{1}{100}[/tex].
In order to find the square root of a fraction, the numerator squared must correct and the denominator squared must be correct.
[tex]1^2 = 1[/tex]
[tex]10^2 = 100[/tex]
This means that we have the values 1 and 10. Therefore one of our fractions is [tex]\frac{1}{10}[/tex].
HOWEVER: A negative number squared is a positive. So this also works:
[tex]-1^2 = 1\\\\-10^2=10[/tex]
So we have [tex]-\frac{1}{10}[/tex] along with [tex]\frac{1}{10}[/tex].
Hope this helped!
Show the conjecture is false by finding a counterexample.
m If m does not equal -1, then < 1.
Dividing any positive number m over (m+1) leads to a positive result that is smaller than one. This is because the denominator is larger than the numerator.
However, if m is negative, then it's a different story. Consider m = -2
If m = -2, then m+1 = -2+1 = -1
Meaning that [tex]\frac{m}{m+1} = \frac{-2}{-1} = 2[/tex] but this result is not less than 1
So m = -2 is one counterexample of infinitely many to show that [tex]\frac{m}{m+1} < 1, \text{ with } m \ne -1[/tex] is not always true. If you restricted m to be positive, then the inequality would be true.

Answer:
1.714
u can round it lol i just put it in a calculator
Answer: 1 and 5/7
Step-by-step explanation: To divide mixed numbers,
first write the mixed numbers as improper fractions.
So here, we can write 2 and 4/7 as the improper fraction 18/7
and we can write 1 and 3/6 as the improper fraction 9/6.
If you need a review of how to write a mixed number
as i improper fraction, let me know below and I will help.
So here, we have 18/7 ÷ 9/6.
Remember that dividing by a fraction is the same
as multiplying by the reciprocal of that fraction.
So here, 18/7 ÷ 9/6 is the same as 18/7 × 6/9.
So now we're simply multiplying fractions.
Remember that when we're multiplying fractions,
we want to cross-cancel first whenever possible.
So here, notice that we can cross-cancel 9 and 18 to 2 and 1.
However, we can't cross-cancel 7 and 6.
So we simply multiply across the numerators
and then across the denominators and we have 12/7.
We can write 12/7 as the mixed number 1 and 5/7.
