The correct response is B.
The value of the variable 'x' will be 25. Then the correct option is B.
What is a cyclic quadrilateral?If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral. And the sum of opposite angles of the quadrilateral is 180 degrees.
Quadrilateral EFGH is inscribed in a circle as shown. ∠F = (4x + 10)°, ∠G = (2x - 5)º, and ∠H = (3x - 5)°.
Angles ∠F and ∠H will be supplementary angles. Then the equation is given as,
∠F + ∠H = 180
4x + 10 + 3x - 5 = 180
7x = 175
x = 25
The value of the variable 'x' will be 25. Then the correct option is B.

m∡4 = 150°
Step-by-step explanation:
m∡1 = 30° because there are 180° in a Δ
m∡4 = 150° because angles 1 and 4 form a linear pair and must add up to 180°
Answer:
answer 180⁰
Step by Step explanation:
All angles in a triangle add up to 180.
1) add up the angles that are already given to you.
50⁰ +100⁰=150⁰.
2)Then take that away from 180⁰. which leaves you with 30⁰
An electronics hobbyist has three electronic parts cabinets with two drawers each.
One cabinet has NPN transistors in each drawer, while a second cabinet has PNP transistors in each drawer. The third cabinet has NPN transistors in one drawer and PNP transistors in the other drawer. The hobbyist selects one cabinet at random and withdraws a transistor from one of the drawers.
a) What is the probability that an NPN transistor will be selected?
b) Given that the hobbyist selects an NPN transistor, what is the probability that it came from the cabinet that contains both types?
c) Given that an NPN transistor is selected what is the probability that it comes from the cabinet that contains only NPN transistors?
Answers
Answer:
a) 0.5 = 50% probability that an NPN transistor will be selected.
b) 0.3333 = 33.33% probability that it came from the cabinet that contains both types
c) 66.67% probability that it comes from the cabinet that contains only NPN transistors
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a) What is the probability that an NPN transistor will be selected?
1/3 probability that the first cabinet is chosen. This cabinet has two transistors, both of which are NPN, so 100% probability of selecting a NPN transistor.
1/3 probability that the second cabinet is chosen. This cabinet has two transistors, both of which are PNP, so 0% probability of selecting a NPN transistor.
1/3 probability that the second cabinet is chosen. This cabinet has two transistors, one of which is NPN, so 50% probability of selecting a NPN transistor.
So
[tex]p = \frac{1}{3}*1 + \frac{1}{3}*0 + \frac{1}{3}*0.5 = \frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = 0.5[/tex]
0.5 = 50% probability that an NPN transistor will be selected.
b) Given that the hobbyist selects an NPN transistor, what is the probability that it came from the cabinet that contains both types?
Here we use the conditional probability formula.
Event A: NPN transistor
Event B: From the third cabinet.
50% probability that an NPN transistor will be selected, so [tex]P(A) = 0.5[/tex].
1/6 probability that it is from the third cabinet and NPN, so [tex]P(A \cap B) = \frac{1}{6}[/tex]
The desired probability is:
[tex]P(B|A) = \frac{\frac{1}{6}}{0.5} = 0.3333[/tex]
0.3333 = 33.33% probability that it came from the cabinet that contains both types.
c) Given that an NPN transistor is selected what is the probability that it comes from the cabinet that contains only NPN transistors?
Either it comes from the cabinet with only NPN transistors, or it comes from the cabinet with both types of transistors. The sum of the probabilities of these outcomes is 100%. So
x + 33.33 = 100
x = 66.67
66.67% probability that it comes from the cabinet that contains only NPN transistors

10.12 as a fraction equals 1012/100
Step-by-step explanation:
To write 10.12 as a fraction you have to write 10.12 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
10.12 = 10.12/1 = 101.2/10 = 1012/100

Answers
Answer:
the answer is 1/2...............
The fraction 1/2 which is equivalent to 4/8 is greater than 1/2.
Given fraction to compare 1/8 or 1/2.
To compare the fraction, the denominator of both fraction should be same.
So, to make denominator same take the LCM of 8 and 2 as
8 = 2 x 2 x 2
2 = 2 x 1
Then, the LCM( 8, 2) = 8.
Now, the fraction can be written as
1/8 or 1/2 x 4/4 = 4/8.
Therefore, the fraction 1/2 is greater than 1/8.

A sel contains eleven elements.
a) How many subsets does it have?
b) How many proper subsets does it have?
Answers
Answers:
a) 2048b) 2047=============================================================
Explanation:
If a set has n elements inside it, then it has 2^n different subsets.
Consider a set like {a,b,c}. It has n = 3 elements.
It has 2^n = 2^3 = 8 subsets
Those 8 subsets are...
{a,b,c} ..... any set is a subset of itself{a,b}{a,c}{b,c}{a}{b}{c}{ } .... the empty setAs you can see, each subset consists of items that are selected from the original set {a,b,c}. We can't have any repeat letters.
In that list, items 2 through 4 represent subsets with exactly two things inside it. Items 5 through 7 are known as singletons as they only have one item inside each set. The empty set can be written with the symbol [tex]\varnothing[/tex] or you could have a pair of braces with nothing inside them. The empty set is a subset of any set.
--------------
Note how I included {a,b,c} as a subset. Any set is a subset of itself.
A proper subset will ignore the original set and only look at smaller subsets. If we say B is a proper subset of A, then set B will have fewer items compared to set A. Without the "proper" in there, it's possible that A = B.
So all we've done really is kick out one set which drops 2^n to (2^n)-1 when counting the number of proper subsets. I'm using parenthesis to indicate the "-1" is not part of the exponent. If you wrote this on your paper, then you would likely write [tex]2^{n} - 1[/tex]
--------------
For this problem, n = 11
This means there are 2^n = 2^11 = 2048 subsets and (2^n)-1 = 2048-1 = 2047 proper subsets.
The number of subset of a set containing 11 elements is 2,048
And, number of proper subset of a set containing 11 element is 2,047.
Here,
A set containing 11 elements.
We have to find number of Subsets and number of Proper subsets.
What is Proper subset of a set?
Set A is considered to be a proper subset of Set B if Set B contains at least one element that is not present in Set A.
Now,
Let a set containing n elements.
then, Number of subsets = [tex]2^{n}[/tex]
And, Number of proper subsets = [tex]2^{n} -1[/tex]
Hence,
A set containing 11 elements.
Number of subsets = [tex]2^{11} = 2,048[/tex]
And, Number of proper subsets = [tex]2^{11} -1 = 2,048 - 1 = 2,047[/tex]
Hence, The number of subset of a set containing 11 elements is 2,048
And, number of proper subset of a set containing 11 element is 2,047.
