At LaGuardia Airport for a certain nightly flight, the probability that it will rain is
0.07 and the probability that the flight will be delayed is 0.19. The probability that it
will not rain and the flight will leave on time is 0.75. What is the probability that it is
raining and the flight is delayed? Round your answer to the nearest thousandth.
Step-by-step explanation:
P(rain and flight delayed) = P(rain) x P(flight delayed) = 0.07 x 0.19
= 0.013 (nearest thousandth)
Answer: 0.01

What is the one shape of cross-section we could create by slicing the cylinder perpendicular to its base
Answer:
rectangle
Step-by-step explanation:
A rectangle represents a figure with four sides having equal opposite sides and the inside angle between the two adjacent sides is ninety degree.
When any plane is made to pass through the cylinder creating a cross section which is perpendicular to its base, it results a two-dimensional cross sectional shape of a rectangle.
Given that MN = 5, NO = 12, and MO = 13, find cos O.
Answer:
12/13
Step-by-step explanation:
Given that MN = 5, NO = 12, and MO = 13, find cos O.
Since the reference angle is P, hence;
MN is the opposite = 5
MO is the hypotenuse = 13 (longest side)
NO is the adjacent = 12
Cos O = adj/hyp
Substitute the given values
Cos O = 12/13
Hence the value of Cos O is 12/13
The index rises 4.9% over the course of the day. What is the value of the index at the end of the day? Round your answer to the nearest hundred.
Answer: $70400
Step-by-step explanation:
Attached is the question:
Based on the information given in the question:
Value of Stock X = 5000 × $4.30 = $21500
Value of Stock Y = 2000 × $3.20 = $6400
Value of Stock Z = 8000 × $4.90 = $39200
Total Stock Value = $67100.
Since there's a 4.9% increase in value of index, the value of the index at end of the day will be:
= $67100 × (100% + 4.9%)
= $67100 × 104.9%
= $67100 × 1.049 =
= $70388
= $70400 approximately

The graph of the function f(x) = ax^2 + bx + c has vertex at (0, 2) and passes through the point
(1, 8). Find a, b and c
Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be [tex](h,k)[/tex]
Another way of representing a quadratic is in "vertex form":
[tex]f(x) = a(x-h)^2+k[/tex]
Now all you have to do is solve for a. You know that the vertex is [tex](0,2)[/tex] and you have know the point of [tex](1,8)[/tex]. Now, all you have to do is plug in these values and solve for a.
[tex]8 = a(1-0)^2+2\\8=a(1)^2+2\\8=a+2\\a=6[/tex]
Now you know the equation is [tex]f(x) = 6(x-0)^2+2[/tex] , but you need it in quadratic form. All you have to do is solve is distribute the 6:
[tex]6x^2+2[/tex]
You get:
a = 6
b = 0
c = 2

pls help how do i solve log(5x+2)=1
like what rule do I use and how do I do it step by step
Answer:
x = -0.2
Step-by-step explanation:
(5x + 2) = 1
- 2 -2
--------------------
5x = -1
Divide each side by 5
-1/5
= -0.2
Check:
(5x + 2) = 1
replace x with -0.2
(-1 + 2) = 1
1 = 1
The equation is true.

Answer:
73 degrees
Step-by-step explanation:
The total number of all of the angles in a triangle added together should be 180 degrees. You know that one of the angles is 17. The other angle is 90 because it is a right triangle.
90 + 17 = 107
180 - 107 = 73
So, the other angle is 73 degrees. If this is wrong I am so sorry. Hope this helps you, let me know if it is right!
Answer:
73°
Step-by-step explanation:
A right triangle has one right angle and two acute angles.
A right angle is 90° and the question says that one of the angle are 17°.
We need to add both angles together which = 107°.
A triangle internal total angles will always add up to 180°.
So we need to do 180° - 107° to find the missing angle which = 73°.
Also, the question said that the missing angles was acute and 73° is acute.
hope this helps :)

Answer:
Step-by-step explanation:
As each step has the same depth and rise, they are respectively 1.2/4=0.3m and 1.8/4=0.45m.
Dividing the steps along the dotted lines, the total rise of the 4 concrete steps = (1+2+3+4)*0.45
= 4.5m
Total concrete volume = total rise * depth * width
= 4.5*0.3*1.8

[tex]\left \{ {{x=3} \atop {y+1=0}} \right.[/tex] solve graphically this linear system of equations
Answer:
The solution is the point (3, -1)
Step-by-step explanation:
We have the system of equations:
x = 3
y + 1 = 0
To solve this graphically, we need to graph these two lines and see in which point the lines intersect.
To graph the line x = 3, we need to draw a vertical line that passes through x = 3.
To graph y + 1 = 0
First we should isolate y.
y = -1
This is graphed as a horizontal line that passes through y = -1
The graph of these two lines can be seen in the image below.
Where the green line is x = 3, and the blue line is y = -1
Now, looking at the graph we can see that the lines do intersect in the point (3, -1)
Then the solution of the system is the point (3, -1)

find the value of each variable 13-17
Answer:
Step-by-step explanation:
Question 13.
By applying cosine rule,
cos(45°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2} }=\frac{10}{y}[/tex]
y = 10√2
By applying sine rule,
sin(45°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2} }=\frac{x}{y}[/tex]
[tex]\frac{1}{\sqrt{2} }=\frac{x}{10\sqrt{2} }[/tex]
x = 10
Question 15.
By applying sine rule,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{y}{32}[/tex]
y = 16√3
By applying cosine rule,
cos(60°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{x}{32}[/tex]
x = 16
Question 17.
By applying sine rule,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{11\sqrt{3} }{y}[/tex]
y = 22
By applying cosine rule,
cos(60°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{x}{y}[/tex]
[tex]\frac{1}{2}=\frac{x}{22}[/tex]
x = 11
What is the factored form of the expressions 4x2 - 25?
Answer:
Explanation: Realize that 4x2−25 is a difference of squares. Differences of squares, such as a2−b2 , can be factored into (a+b)(a−b) . Since 4x2=(2x)2 and 25=(5)2 , we can say that 4x2−25=(2x+5)(2x−5)
Step-by-step explanation:
Answer:
(2x + 5)(2x - 5)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
4x² = 2²x²= (2x)²
25= 5* 5 = 5²
4x² - 25 = (2x)² - 5² {a= 2x ; b = 5}
= (2x + 5)(2x - 5)

Step-by-step explanation:
Please show me step by step how to do this
Answer:
48
Step-by-step explanation:
The nth term of an AP is expressed as;
Tn = a+(n-1)d
Id 12th term is 32, hence;
T12 = a+11d
32 = a+11d ...1
If the 5th term is 18, then;
T5 = a+4d
18 = a + 4d ....2
Subtract 1 from 2;
32 - 18 = 11d - 4d
14 = 7d
d = 14/7
d = 2
From 1; 32 = a+11d
32 = a+ 11(2)
32 = a + 22
a = 32-22
a = 10
Get the 20th term
T20 = a+19d
T20 = 10 + 19(2)
T20 = 10 + 38
T20 = 48
Hence the 20th term is 48

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that the rate of Rs 105 per US Dollar,
We have to calculate the US Dollars for Rs 21000.
105 Rs = 1 USD
