In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse.
If b = 6.8 centimeters and c = 9.7 centimeters, what is the perimeter? If necessary, round to
the nearest tenth.
Answer:
P=23.4
Step-by-step explanation:
so using the pytogoren theroum
c2-b2= a2
so a= 6.9
so P= 6.9+6.8+9.7=23.4

Answer:
Area = 113.01 m²
Step-by-step explanation:
From the picture attached,
Area of the quadrilateral ABCD = Area of triangle ABC+ Area of triangle ACD
Construction to be done → Draw a perpendicular from a point A to the opposite side CD
Area of Δ ABC = [tex]\frac{1}{2}(AB)(BC)[/tex]
= [tex]\frac{1}{2}(12)(10)[/tex]
= 60 m²
Area of triangle ACD = [tex]\frac{1}{2}(AE)(CD)[/tex]
From ΔAEC,
sin(29°) = [tex]\frac{AE}{AC}[/tex]
AC = [tex]\sqrt{(12)^2+(10)^2}[/tex] [By Pythagoras theorem]
AC = [tex]\sqrt{244}[/tex]
AC = 15.62 m
Therefore, AE = 15.62sin(29)
= 7.57 m
Area of ΔACD = [tex]\frac{1}{2}(7.57)(14)[/tex]
= 53.01 m²
Area of ABCD = 60 + 53.01
= 113.01 m²

An airline claims that there is a 0.10 probability that a coach-class ticket holder who flies frequently will be upgraded to first class on any flight. This outcome is independent from flight to flight. Sam is a frequent flier who always purchases coach-class tickets.
For the following questions, pick the correct value rounded to the nearest hundredth.
What is the probability that Sam will be upgraded exactly 3 times in his next 20 flights?
What is the probability that Sam will be upgraded at most 4 times in his next 20 flights?
What is the probability that Sam’s first upgrade will occur on the third flight?
Answer:
b
Step-by-step explanation:
a) The probability that Sam will be upgraded exactly 3 times in his next 20 flights is 19.01 %
b) The probability that Sam will be upgraded at most 4 times in his next 20 flights is 95.68 %
c) The probability that Sam’s first upgrade will occur on the third flight is 0.0729
What is a Binomial Distribution?
The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.
The formula for Binomial Distribution is given by
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the probability of getting a coach-class ticket be p
The value of p = 0.10
a)
The probability that Sam will be upgraded exactly 3 times in his next 20 flights
The number of trials = 20
The probability of success p = 0.10
The probability of failure q = 1 - p
The probability of failure q = 0.90
x = 3
Substituting the values in the equation , we get
P ( 3 ) = [ 20! / ( 17 )! 3! ] ( 0.10 )³ ( 0.90 )¹⁷
P ( 3 ) = 0.1901
P ( 3 ) = 19.01 %
b)
The probability that Sam will be upgraded at most 4 times in his next 20 flights
The number of trials = 20
The probability of success p = 0.10
The probability of failure q = 1 - p
The probability of failure q = 0.90
x ≤ 4
Substituting the values in the equation , we get
P ( x ≤ 4 ) = [ 20! / ( 16 )! 4! ] ( 0.10 )⁴ ( 0.90 )¹⁶
P ( x ≤ 4 ) = 0.9568
P ( x ≤ 4 ) = 95.68 %
c)
The probability that Sam’s first upgrade will occur on the third flight
A = ( 0.9 ) ( 0.9 ) ( 0.9 ) ( 0.1 )
A = 0.0729
A = 7.29 %
Hence , the solution is calculated by binomial distribution

Becky is using the expression 2z + 3 to represent the number of chairs in her classroom. There are twice as many chairs as tables, and there are three extra chairs in the back. What does z represent?
The number of chairs.
The number of tables.
The number of chairs at tables.
The number of chairs and tables.
Answer:
The number of chairs
Step-by-step explanation:
The equation is 2z + 3
2 ( = multiply by)
z ( # of chairs)
+3 ( the 3 extra chairs in the back)
Answer:
The number of tables
Step-by-step explanation:
Sens there is twice as many chairs as tables, the number 2 represents the chairs. The 3 represents the 3 extra chairs in the back. so the only logical object to represent z is the number of tables.

Step-by-step explanation:
The inscribed angle is half the measure of its intercepted arc, that is
3x + 5 = 0.5 × 46 = 23 ( subtract 5 from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
Answer:
x = 6

Evaluate the expression if b= 6 and c= 10.
5b/c
Answer:
=3
Step-by-step explanation:
5b/c
=5*6/10
=30/10
=3
Answer:
If b = 6 and c = 10, the value of an expression is 3.
Step-by-step explanation:
Given the expression
[tex]\frac{5b}{c}[/tex]
We have to evaluate the expression if b = 6 and c = 10.
Important Tip:
In order to evaluate the expression [tex]\frac{5b}{c}[/tex], all we need to do is to substitute the value of b and c in the expression.
As the expression is
[tex]\frac{5b}{c}[/tex]
substitute b = 6 and c = 10 in the expression
[tex]\frac{5b}{c}=\frac{5\left(6\right)}{10}[/tex]
[tex]=\frac{30}{10}[/tex]
[tex]=3[/tex] ∵ [tex]\frac{30}{10}=3[/tex]
Therefore, if b = 6 and c = 10, the value of an expression is 3.

If these two shapes are similar, what is the measure of the missing length b?
Answer:
B = 7mm
Step-by-step explanation:
This is probably an enlargement problem.
To solve this:
the blue triangle has all of it's measurements you need. Let's start with that.
6/36 =
We know that one side, the bottom side of the green triangle is 42mm.
6/36 = b/42
We could simplify 6/36 into 1/6
1/6 = b/42
AHA! the denominators are easy! 6 times 7 is equal to 42, so 1 times 7 should equal b!
1/6 = 7/42
Check:
6/36 = b/42
36b = 6*42
36b = 252
b = 252/36
b = 7
So yes! B is 7 mm. Pls mark me brainliest, as I never have a single brainliest.
