Over the course of a week, an airline has 42 flights between New York and Los Angeles. Of these flights, 28 are considered
to be "on-time."
If you chose a particular flight at random, what is the probability that it would not be on-time? Express your answer as a
fraction.
Provide your answer below:
Answer:
The probability that a particularly randomly chosen flight will not be on time is 1/3
Step-by-step explanation:
The number of flights available between New York and Los Angelis = 42 flights
The number of flights that are considered to be on time = 28 flights
The probability that a particularly randomly chosen flight will not be on time = 1 - The probability that the flight will be on time
The probability that the flight will be on time = (The number of flights considered to be on time)/(The total number of flights available)
The probability that the flight will be on time = 28/42 = 2/3
∴ The probability that a particularly randomly chosen flight will not be on time = 1 - 2/3 = 1/3
The probability that a particularly randomly chosen flight will not be on time = 1/3.

Centroid is that point where median draw from the center of each side in a triangle meet.
What is centroid?The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians.
Let,
There is a triangle ΔABC

Answer:
-12, 4
Step-by-step explanation:
7^-9 x 7^-3 = 7^-12
When you multiply exponents with the same base, you add them.
11^-4/11^-8 = 11^4
When you subtract exponents with the same base, you subtract the exponent in the numerator by the exponent in the denominator.
Suzanne Attired makes fashionable garments. During a particular week employees worked 360 hours to produce a batch of 132 garments, of which 52 were seconds (meaning they were flawed). Seconds are sold for $90 each at Attired's Factory Outlet Store. The remaining 80 garments are sold for $200 each. What is the labor productivity ratio of this manufacturing process
Answer:
$57.44 per hour
Step-by-step explanation:
Given that :
Hours worked = 360 hours
Production = 132 batches of garment
Of the 152:
52 were flawed (sold at $90 each)
80 were sold at $200 each
Labor productivity ratio: (output value / input value (hours worked))
Output value = [(52*$90) + (80*$200)]
Output value = $20,680
Labor productivity ratio = $20,680 / 360 hours
Labor productivity ratio = $57.44 per hour

Find the equation of the perpendicular bisector of AB when A(-7,2) and B(3,4)
Given:
Two points are A(-7,2) and B(3,4).
To find:
The perpendicular bisector of AB.
Solution:
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Slope of AB is
[tex]m_1=\dfrac{4-2}{3-(-7)}[/tex]
[tex]m_1=\dfrac{2}{3+7}[/tex]
[tex]m_1=\dfrac{2}{10}[/tex]
[tex]m_1=\dfrac{1}{5}[/tex]
Procut of slopes of perpendicular line is -1.
So, slope of perpendicular bisect is opposite of reciprocal of [tex]\dfrac{1}{5}[/tex].
[tex]m_2=-5[/tex]
Midpoint of AB is
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-7+3}{2},\dfrac{2+4}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{6}{2}\right)[/tex]
[tex]Midpoint=\left(-2,3\right)[/tex]
Slope of perpendicular bisector is -5 and it passes through (-2,3), so the equation of perpendicular bisector is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-3=-5(x-(-2))[/tex]
[tex]y-3=-5(x+2)[/tex]
[tex]y-3=-5x-10[/tex]
Add 3 on both sides.
[tex]y=-5x-10+3[/tex]
[tex]y=-5x-7[/tex]
Therefore, the equation of perpendicular bisector is [tex]y=-5x-7[/tex].

which equation represents this sentence? one half the sum of a number and four is less than the quotient of five and the number
Answer:
The fourth one
Step-by-step explanation:
Three less then the quotient means you are subtracting 3 from a division problem. 1/2 the sum of a number and four means that there is going to be a variable and 4 in parenthesis that you will add before you multiply by 1/2.
Which of the following steps could be used to solve the equation 93 = x + 58?
Answer:
x=35
Step-by-step explanation:
93=x+58
-58 -58
35=x
x=35
Simply subtract 58 on both sides so it crosses out, isolating x.
Also x would be 35 in case you need that.
Is this right pls tell me ASAP

Given 45-45-90 triangle with hypotenuse of 3cm solve for the other sides.
Answer:
[tex]\sqrt{\frac{9}{2} }[/tex]
Step-by-step explanation:
Given dimensions:
The right angle system is a 45 - 45 - 90
Hypotenuse = 3cm
Unknown:
Adjacent and opposite sides = ?
Solution:
In this triangle, the adjacent and opposite sides are equal to one another. So,
Let adjacent = y
opposite = y
For right angle triangles as this, using the Pythagoras theorem,
hypotenuse² = adjacent² + opposite²
Insert the parameters and solve;
3² = y² + y²
2y² = 9
y² = [tex]\frac{9}{2}[/tex]
y = [tex]\sqrt{\frac{9}{2} }[/tex]
