Answer:
X ~ (350, 0.5)
0.00009
Step-by-step explanation:
Given that:
Daily passenger volume = 350
Since both airlines A and B have equal probability ;
p = 0.5
n = 350
X ~ (n, p)
X ~ (350, 0.5)
B.)
Mean, m= np = 350 * 0.5 = 175
Standard deviation, s = sqrt(np(1-p)) = sqrt(350*0.5*0.5) = sqrt(87.5)
Obtaining standardized score, Z
Z = (x - m) / s
x = 210
Z = (210 - 175) / sqrt(87.5)
Z = 35 / sqrt(87.5)
Z = 3.74
P(Z > 3.74) = 0.00009 (Z probability calculator)

Is it possible for a triangle to have the three angle measurements 7cm, 24cm, 25cm and is it congruent or not?
Answer:
The Answer is yes to both of your questions.
Step-by-step explanation:
SSS (Side angle Side) = Because If 3 sides of triangle are congruent to 3 sides of another triangle, the triangles are congruent. SAS (Side angle side) = If 2 sides and the angle in between are congruent to the corresponding parts of another triangle, the triangles are congruent.

The box plots below show student grades on the most recent exam compared to overall grades in the class
which of the following best describes the information about the medians
1. the exam outlier at 60 makes the IQR narrower and the median higher
2. The class data is more evenly spread which pulls its medium down
3. The class median is lower than the exam median
4. The class Q3 is higher than the exam Q3
Answer:
3. The class median is lower than the exam median
Step-by-step explanation:
The median of the box plot is indicated by the vertical line that divides the box.
Thus, the Class median grade is about 80, while the Exam median grade is more than 80.
Comparing grades, this means that the class median is lower. than the exam median.
Therefore, "the class median is lower than the exam median" is the right information that describes the median.
Answer:
C- The class median is lower than the exam median

The inverse
Answer:
Step-by-step explanation:
find the inverse of the function y=9x+12
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=9x+12 becomes x=9y+12.
Now, solve the equation x=9y+12 for y.
[tex]f^{-1}[/tex](x) = (x-12)/9
y=(x−12)/9
In a normally distributed data set with a mean of 24 and a standard deviation of 4.2, what percentage of the data would be between 19.8 and 28.2 and why
Answer:
By the Empirical Rule, 68% of the data would be between 19.8 and 28.2
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 24
Standard deviation = 4.2
What percentage of the data would be between 19.8 and 28.2
19.8 = 24 - 4.2
28.2 = 24 + 4.2
So within one standard deviation of the mean
By the Empirical Rule, 68% of the data would be between 19.8 and 28.2
write a word problem whose solution is $111
Answer:
Step-by-step explanation:
Word problem is a topic in mathematics that involves the interpretation of a given question with a mathematical expression so as to determine the value of the required variable.
Example: The price of a pencil is $10, and that of a ruler is $15.25. If Charles bought 5 pencils and 4 rulers, calculate the total amount of money spent.
price of a pencil = $10
price of a ruler = $15.25
Then,
cost of 5 pencils = $10 x 5
= $50
cost of 4 rulers = $15.25 x 4
= $61
Total amount of money spent by Charles = $50 + $61
= $111
The total amount of money spent by Charles is $111.
Two numbers differ by 5. The sum of their squares is 193. Find the numbers.
Answer:
Let one number be x and the other be (x-5)
Step-by-step explanation:
x^2+(x-5)^2=193
x^2+x^2-10x+25=193
2x^2-10x+25=193
Subtract 193 from both sides of the equation.
2x^2-10x-168=0
x=12 or x=-7
x-5=7 or x-5=-12

For each expression, write an equivalent expression by applying the distributive
property.
2. (x + 4)(2x - 1)
The equivalent expressions are:
x² + 11x + 18
2x² + 7x - 4
x² - 10x + 25
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
(x + 2) (x + 9)
(x + 4) (2x - 1)
(x - 5)²
Now,
Applying the distributive property.
1)
(x + 2) (x + 9)
x² + 9x + 2x + 18
x² + 11x + 18
2)
(x + 4) (2x - 1)
2x² - x + 8x - 4
Combining the like terms.
2x² + 7x - 4
3)
(x - 5)²
(x - 5) (x - 5)
x² - 5x - 5x + 25
x² - 10x + 25
Thus,
The equivalent expressions are:
x² + 11x + 18
2x² + 7x - 4
x² - 10x + 25

Answer: x=1/2
Step-by-step explanation: You want to get the x on one side of the equal sign, by itself. First you subtract (18/4) from both sides. 5 - (18/4) =1/2 So that’s your answer.
