Answer:
The probability that the flight would be delayed when it is raining is 0.571
Step-by-step explanation:
Here, we want to find the probability that given that it is raining, what is the probability that the flight will be delayed
Let A be the event that flight will be delayed
P(A) = 0.15
Let B be the event that it will rain
P(B) = 0.07
P(A n B) = 0.04
Thus;
P(A|B) = P(A n B)/P(B) = 0.04/0.07 = 0.571

If Shelby chooses one of her friends at random, what is the probability that this friend’s favorite flavor is either strawberry or vanilla?
Answer:2/5
Step-by-step explanation: because 6 people in total like strawberry or vanilla so you get the probabliluty of 6/15 and when you simplify it you get 2/5

Find the discriminant.
Determine the number
of real solutions.
Answer:
The discriminant is 0
There is 1 real solution
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
In the equation y = x² - 4x + 4, a is 1, b is -4, and c is 4.
Plug in these values into the formula:
D = b² - 4ac
D = (-4)² - 4(1)(4)
D = 16 - 4(4)
D = 16 - 16
D = 0
So, the discriminant is 0.
With a discriminant of zero, there is one real solution.
So, the number of real solutions is 1.

Please help me quick please solve in inequality form
Answer:
D. The sum of twice number and six is no more than five.
Step-by-step explanation:
In the inequality,
[tex]2n+6\leq 5[/tex]
The number (n) is multiplied by (2), therefore options (A) and (B) can be ruled out since they have the statement, "twice the sum of a number and six". Moreover, one can see the inequality sign indicates that this value is less than or equal to (5). Thus, one of the possible solutions to this equation is (5), therefore, option (C) is incorrect. Therefore, the only remaining correction option is option (D).

The circumferance of the given circle is C = 8π.
What is a circle?A circle is a shape consisting of all points in a plane that are at a constant distance from a given point called the center. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.The general form of the equation of a circle is:x² + y² + 2gx + 2fy + c = 0.
The standard equation of a circle is -(x - x₁)² + (y - y₁)² = r²
The parametric equation of circle can be written as -x² + y² + 2hx + 2ky + C = 0 where x = - h + rcosθ and y = - k + rsinθ.
Given is a circle that has a diameter of 8 meters.
We can write the circumferance of the circle as -
C = 2πr
C = 2π (d/2)
C = 2π (8/2)
C = 8π
Therefore, the circumferance of the given circle is C = 8π.

Which summation formula represents the series below?
13 + 9 + 5 + 1
∑(17-4n) is the summation formula represents the series 13 + 9 + 5 + 1.
What is Series?A series is the cumulative sum of a given sequence of terms.
The given expression is 13 + 9 + 5 + 1
The terms of this series are 13,9,5,1
It is an AP. Here, first term is 13 and common ratio is -4.
The nth term of an AP is
aₙ=a+(n-1)d
=13+(n-1)(-4)
=13-4n+4
=17-4n
The summation formula of an Arithmetic progression is
∑aₙ
The value of n is 4 because the number of term is 4. So, the summation formula is
∑(17-4n)
Hence ∑(17-4n) is the summation formula represents the series
13 + 9 + 5 + 1.

The length of a rectangular map is 37,5 cm and the perimeter is 125 cm. Find the width
Let the length of the map be L Cm.
Hence, L = 37.5 Cm
Now, Let the width of the map be B.( Breadth )
Now, we know that perimeter of a rectangle
= 2 ( L + B )
According to the question–
125 = 2 ( L + B )
{ Putting the value of L we get }
Or, 125 = 2 ( 37.5 + B )
Or, 125/2 = 37.5 + B
Or, 62.5 = 37.5 + B
Or, 37.5 + B = 62.5
Or, B = 62.5 – 37.5
Or, B = 25 Cm
Therefore, the Width of the rectangle is 25 Cm.

Consider this equation
cos(0)=-3/10
If 0 is an angle in quadrant II, what is the value of tan (0)
square root 91 / 10
square root 91/ 3
square root - 91/10
or square root - 91/3
Answer:
square root -91/3
Step-by-step explanation:
just took the test
The right option is missing. The correct answer is tan(0) = -(√91)/3.
The trigonometric expression tan(0) has a value of -(√91)/3 when cos(0) = -3/10.
What are trigonometric functions?The values of all trigonometric functions dependent on the value of the ratio of sides of a right-angled triangle are known as trigonometric ratios. The trigonometric ratios of a right-angled triangle's sides about any of its acute angles are known as that angle's trigonometric ratios.
The three sides of the right-angled triangle are:
Hypotenuse (the longest side)
Perpendicular (opposite side to the angle)
Base (Adjacent side to the angle)
The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
The trigonometry ratios for a specific angle ‘θ’ is given below:
Trigonometric Ratios:
Sin θ = Perpendicular/Hypotenuse
Cos θ = Base/Hypotenuse
Tan θ = Perpendicular/Base or Sin θ/Cos θ
Cot θ = Base/Perpendicular or 1/tan θ
Sec θ = Hypotenuse/Base or 1/cos θ
Cosec θ = Hypotenuse/Perpendicular or 1/sin θ
What is Pythagoras theorem?According to the Pythagoras theorem, we can say that in a right-angled triangle:
Hypotenuese² = Base² + Perpendicular²
How do we solve the given question?We are given cos(0) = -3/10, 0 being an obtuse angle (90° < 0 < 180°, since 0 is an angle in quadrant II)
We need to remember that in quadrant II, sine is always positive, cosine is negative, and tangent is also negative.
We are asked to find the value of tan(0).
We know cos(0) = Base/Hypotenuse.
So we let the hypotenuse be 10k, and let the base be 3k. Let the perpendicular be p.
By Pythagoras' Theorem,
Hypotenuese² = Base² + Perpendicular²
or, (10k)² = (3k)² + p²
or, 100k² = p² + 9k²
or, p² = 100k² - 9k² = 91k² = (k√91)²
or, p = k√91
Now, we can find the value of tan(0):
tan(0) = Perpendicular/Base = -(k√91)/3k = -(√91)/3
(Negative value taken as tan is negative in quadrant II)
∴ The trigonometric expression tan(0) has a value of -(√91)/3 when cos(0) = -3/10.

The order pair associated with t-value of -1 is?
Answer:
The ordered pair associated with a t-value of -1 is (-3, 1).
Step-by-step explanation:
Substitute the t-value, or -1, into both of the equations to find the pairs.
x = t - 2
x = (-1) - 2
x = -3
y = t^2
y = (-1)^2
y = 1
