The probability of being marked tardy when events are mutually exclusive is 0.8, and when they are independent, the probability is 0.09.
Explanation:
The probability that a student will be marked tardy if the events on-time and marked tardy are mutually exclusive is 0.9 - 0.1 = 0.8. When events A and B are independent, the probability of both events occurring is the product of their individual probabilities: P(A and B) = P(A) * P(B). In this case, P(on-time) * P(tardy) = 0.1 * 0.9 = 0.09.

What is the vertex of the function: f(x) = x² + 12x ? Please explain.
(–6, 0)
(-6, -36)
(6, 0)
(6, –36)
The vertex of the function is (-6,-36).
Step-by-step explanation:
f(x) = x²+ 12x
From the above function, we can find the x- coordinate of the vertex as,
x = -b/2a
Here a = 1, b = 12
Plugin the values as,
x = -12 /(2×1) = -6
Now plug in the x value in the above function, we will get y as,
f(x) = y = x² + 12x = (-6)² + 12(-6)
= 36-72 = -36
So the vertex is (-6, -36).

Distributive property: 5y-3y-6
Combine like terms: 2y-6
So there's your answer
To simplify the given expression, distribute the -3 to both terms inside the parentheses, then combine like terms.
Explanation:To simplify the expression 5y - 3(y + 2), we need to follow the order of operations, which is parentheses first, then multiplication and division, and finally addition and subtraction.
First, distribute the -3 to both terms inside the parentheses:
5y - 3 * y - 3 * 2

Suppose θ is an angle in the standard position whose terminal side is in Quadrant IV and cotθ= -2/17 . Find the exact values of the five remaining trigonometric functions of θ.
Final answer:
Given an angle θ in Quadrant IV with cotθ = -2/17, a right triangle is formed. Using the Pythagorean theorem, the hypotenuse is calculated, and the five additional trigonometric functions of θ are determined with appropriate signs for Quadrant IV.
Explanation:
If θ is an angle in the standard position whose terminal side is in Quadrant IV and cotθ = -2/17, we can find the five remaining trigonometric functions.
The cotangent of an angle θ, which is the reciprocal of the tangent, tells us that the tangent of θ is -17/2. Since the angle is in Quadrant IV, where cosine and secant are positive but sine and cosecant are negative, we can form a right triangle within the coordinate plane to represent this scenario. In this triangle, the adjacent side (x) to the angle θ will be positive, and the opposite side (y) will be negative.
Using the Pythagorean theorem, if we assume the adjacent side to be 17 (because cotθ = adjacent/opposite), and the opposite side to be -2 (to make cotθ = 17/(-2) = -2/17), the hypotenuse (r) can be calculated as:
√(17² + (-2)²) = √(289 + 4) = √293
Now we can find the other five trigonometric functions:
Sinθ = opposite/hypotenuse = -2/√293Cosθ = adjacent/hypotenuse = 17/√293Tanθ = opposite/adjacent = -2/17 (which was given)Cscθ = hypotenuse/opposite = -√293/2Secθ = hypotenuse/adjacent = √293/17The signs of these values are consistent with the properties of trigonometric functions in the fourth quadrant.

If Lin wants to save 75$ for a trip to the city and has already saved 37.50 so far what percentage of her goal has she saved
Answer:
50%
Step-by-step explanation:
Let X be the % of total that she has saved
X/100 x 75 = 37.50
75X = 37.50 x 100
X = 37.50 x 100 / 75
= 3750/75
= 50%
a jet travels 520 miles in 5 hours at this rate how far could the jet fly in 11 hours what is the rate of speed of the jet
The rate of speed of jet is 104 miles per hour
The jet could cover 1144 miles in 11 hours
Solution:Given that,
A jet travels 520 miles in 5 hours
Find the miles traveled in 1 hour ( speed in miles per hour)[tex]speed = \frac{distance}{time}[/tex]
[tex]Speed = \frac{520}{5}\\\\Speed = 104\ miles\ per\ hour[/tex]
How far could the jet fly in 11 hoursTime = 11 hours
Speed = 104 miles per hour
[tex]Distance = speed \times time\\\\Distance = 104 \times 11\\\\Distance = 1144[/tex]
Thus the jet could cover 1144 miles in 11 hours
What scenario below represents 85% earning 56 out of 70 points on a test are you 78 out of 90 points on a test earning 102 out of 120 points on a test
Answer:
The scenario that represents a 85% of success on a test is C. 102 out of 120 points
Step-by-step explanation:
Let's analyze which of the scenarios given, represent a 85% of success on a test, this way:
Scenario A:
56 out of 70 points = 56/70 = 0.8
This scenario represents a 80% of success
Scenario B:
78 out of 90 points = 78/90 = 0.867
This scenario represents a 86.7% of success
Scenario C:
102 out of 120 points = 102/120 = 0.85
This scenario represents a 85% of success
find the next 3 terms in the sequence:30,22,14,6
A.-3,-12,-21
B.-1,-8,-15
C.-1,-2,3
D.-2,-10,-18
Answer:
D
Step-by-step explanation:
Note the difference between consecutive terms is constant, that is
22 - 30 = - 8
14 - 22 = - 8
6 - 14 = - 8
To obtain a term in the sequence subtract 8 from the previous term, thus
6 - 8 = - 2
- 2 - 8 = - 10
- 10 - 8 = - 18
The next 3 terms in the sequence are - 2, - 10, - 18 → D
Find the LCM of 91, 143 and 169
Answer:
13013
Step-by-step explanation:
Express each number in terms of the product of prime numbers.
91 = 7 × 13
143 = 11 × 13
169 = 13 × 13
Now consider the maximum number of times each factor occurs for each number.
The factor 7 occurs once
The factor 11 occurs once
The factor 13 is repeated twice ( maximum number of times for 1 number )
Thus LCM = 7 × 11 × 13 × 13 = 13013
91 = 7×13
143 = 11×13
169 = 13²
LCM = 7×11×13² = 77×169 = 13013

A) Equation: f = 2.75p
B) 38.5 cups of flour are needed to make 14 pound cakes
Step-by-step explanation:
A)
The table shows the following data:
Pound cakes, p 3 6 9
Cups of flour, f 8.25 16.5 24.75
From the table, we notice that the increase in cups of flour needed per increase in pound cakes is:
[tex]m=\frac{16.5-8.25}{6-3}=\frac{8.25}{3}=2.75[/tex]
This means that for each additional pound cake, we need 8.25 more cups of flour.
This is a direct relationship between the two variables, therefore we can write their relationship using the equation:
[tex]f=2.75 p[/tex]
B)
Now we can complete the table.
We have to found how many cups of flour are needed when the number of pound cakes is
p = 14
In order to do that, we use the equation found in part A):
f = 2.75p
And substituting p = 14 into the equation, we find
f = (2.75)(14)= 38.5
Which means that 38.5 cups of flour are needed to make 14 pound cakes.

cos^2x+sin^2x/cot^2x-csc^2x
[tex]\frac{cos^2x + sin^2x}{cot^2x - cosec^2x} = -1[/tex]
Solution:
Given trignometric expression is:
[tex]\frac{cos^2x + sin^2x}{cot^2x - cosec^2x}[/tex]
We have to evaluate the above expression
Let us use the trignometric identities
[tex]sin^2x + cos^2x = 1[/tex]
Also, use another trignometric identitiy
[tex]1 + cot^2x = cosec^2x[/tex]
Therefore, upon rearranging we get,
[tex]cot^2 x -cosec^x = -1[/tex]
Apply these two identities in given expression
[tex]\frac{cos^2x + sin^2x}{cot^2x - cosec^2x} = \frac{1}{-1}\\\\\frac{cos^2x + sin^2x}{cot^2x - cosec^2x} = -1[/tex]
Thus value of given expression is -1

At a given time of day , the ratio of the height of an object to the length of its shadow is the same for all objects. If a 4-ft stick in the ground casts a shadow of 2.4 ft, find the height of a tree that casts of shadow that is 23.04ft.
Answer:
38.40 ft
Step-by-step explanation:
The problem statement tells you the proportion is ...
height/shadow = (4 ft)/(2.4 ft) = (tree height)/(23.04 ft)
Multiplying by 23.04 ft, we find ...
tree height = (23.04 ft)(4/2.4) = 38.40 ft
The height of the tree is 38.40 ft.

Claire is buying a new bicycle for $295. If the
sales tax is 4.75%, what will she pay in total?
Answer:
$309.01
Step-by-step explanation:
To calculate tax, you need to turn the percent to a decimal. This is done by moving the decimal point two spaces to the left, adding zeros and needed.
4.75% = 0.0475
Now take the price of the bike, 295, and multiply it by 0.0475.
295 x 0.0475 = 14.0125
All you need are the first two numbers after the decimal point since you are dealing with money.
Add the product, 14.01, to the price of the bike, 295, and you have your answer.
$309.01
Hope this helps.

A graduated cylinder is filled with 36 cm 3 of liquid the liquid is poured into a different cylinder that has a radius of 3cm , what will the height of the liquid be in the new cylinder ?
The height of the liquid in the new cylinder is about 1.72 cm
Step-by-step explanation:
The formula of the volume of a cylinder is V = πr²h, where
r is the radius of the base of the cylinderh is the height of the cylinder∵ The volume of the liquid = 36 cm³
∵ The liquid is poured into another cylinder with radius 3 cm
∵ The radius of the base = 3 cm
- To find the height of the liquid in the new cylinder equate the rule
of the volume by 36
∵ V = πr²h
∴ π(3)²h = 36
∴ 9πh = 36
- Divide both sides by 9π
∴ h = 1.273239545
The height of the liquid in the new cylinder is about 1.72 cm
