The vertex form of the given equation, y = -6x² + 3x + 2, is expressed as: y = -6(x - 0.25)² + 2.375.
What is an Equation in Vertex Form?The vertex form of an equation is expressed as, y = a(x - h)² + k, where:
(h, k) = vertex of the parabola.
Given the equation, y = -6x² + 3x + 2, factor the equation:
y = -6(x² - 0.5x) + 2
y = -6(x² - 0.5 + 0.0625) + 2.375
Rewriting the equation as perfect squares, we would have:
y = -6(x - 0.25)² + 2.375
The vertex form of y = -6x² + 3x + 2 is, y = -6(x - 0.25)² + 2.375.

Answer:
a) mean = 147
b) median = 147
c) mode = 152
d) range = 65
Step-by-step explanation:
firsly let’s arrange the numbers of the set in ascending order:
117 , 119 , 138 , 142 , 152 , 152 , 174 , 182
a)
[tex]Mean = \frac{117+119+138+142+152+152+174+182}{8} =\frac{1176}{8} =147[/tex]
b) the median is the average of the two middle numbers :
[tex]117,119,138, \frac{142,152}{} , 152,174,182[/tex]
[tex]median=\frac{142+152}{2}= 147[/tex]
c) the modal height is 152 because 152 is the value that appears most frequently (2 times) in our set
d) the range of a set is the difference between the highest and lowest numbers :
Then
the range = 182-117 = 65

An airline gathers data on late departures and early arrivals over a month. it finds that the probability of a late departure is 12 percent, the probability of an early arrival is 27 percent, and the probability of both a late departure and an early arrival is 4 percent. which equation shows how to correctly calculate the probability of a late departure or an early arrival? p(late departure or early arrival) = 0.12 0.04 p(late departure or early arrival) = 0.12 0.27 p(late departure or early arrival) = 0.12 0.27 – 0.04 p(late departure or early arrival) = 0.27 0.04 – 0.12
Answers
The probability of a late departure or an early arrival P(late departure or early arrival) = 0.12 + 0.27 – 0.04
What is probability?
The probability is defined as the chances of occurence of any event from the sample.
Given: The probability of a late departure is 12 %t, the probability of early arrival is 27%.
i.e. P(late departure)=0.12
P(an early arrival)=0.27
The probability of both a late departure and an early arrival is 4 percent.
P(late departure and early arrival) =0.04
Now, using the formula the probability of the union of two dependent events A and B:-
[tex]\rm P(AUB)=P(A)+P(B)-P(A \cap B)[/tex]
i.e. P(late departure or early arrival) = P(late departure)+P(an early arrival)-P(late departure and early arrival)
=0.12+0.27-0.0.04
Hence, the required equation : P(late departure or early arrival) = 0.12 + 0.27 – 0.04
To know more about probability follow
https://brainly.com/question/24756209
The equation that shows how to correctly calculate the probability of a late departure or an early arrival is P(L∪E)=0.12+0.27-0.04.
Probability of late departure P(L) = 0.12
Probability of early arrival P(E) = 0.27
Probability of both a late departure and an early arrival P(L∩E)= 0.04
What is probability?Probability is the measurement of the likelihood of an event.
P(L∪E)=P(L)+P(E)- P(L∩E)
Where P(L∪E) is the probability of a late departure or an early arrival.
So, P(L∪E)=0.12+0.27-0.04
Hence, the equation that shows how to correctly calculate the probability of a late departure or an early arrival is P(L∪E)=0.12+0.27-0.04.

Answers
The difference in the pay rate of Phoebe in 5 years will be $11850
How to calculate the pay?Your information is incomplete. Therefore, an overview will be given. Let's assume that the pay rate is $20000. When there is a 5% increase, the new pay rate will be:
= $20000 + (5% × $20000)
= $20000 + $1000
= $21000
When there is $0.75 increase per hour, the new pay rate on 5 years will be:

= $32850
The difference will be:
= $32850 - $21000

What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As it is given that Leroy's total job benefits were $50,150. while his total job expenses for traveling and for professional development for the year were $3,500. As the total employment compensation is the amount that is the difference between job benefits and job expenses. Therefore,
[tex]\rm Total\ employment\ compensation= Job\ benefits + Job\ expenses[/tex]

Figure ABcD is a parallelogram. If point C lies on the line x=2, what is the y-value of point C?
Answers
The value of y in point C is 0. So, C is located at (2, 0) in the Cartesian plane.
Given that a parallelogram ABCD is shown in the Cartesian plane.
The points are:
A = (-1, 2)
B = (2, 3)
C = (2, y)
D = (-1, -1)
We are asked to find the value of y in the point C.
To find the value of y in point C, we can use the fact that the slope of line AB is equal to the slope of line DC, and the slope of line BC is equal to the slope of line DA.
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:
slope = (y₂ - y₁) / (x₂ - x₁)
Let's calculate the slope of line AB and DC:
Slope of AB = (3 - 2) / (2 - (-1))
= 1 / 3
∴ Slope of DC = 1 / 3.
So,
1/3 = (y+1) / (2+1)
1/3 = (y + 1) / 3
y + 1 = 1
y = 0
Hence, we get the value of y in point C is 0.

What is projectile motion?Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory
Projectile motion
We are told that the projectile motion of an object can be modeled using;
h(t) = gt² + v0*t + h0
Where;
g is the acceleration due to gravity
t is the time since launch
h(t) is the height of the projectile after time t
v0 is the initial velocity
h0 is the initial height.
Now, we are given;
The acceleration due to gravity; g = –9.8 m/s²
Initial velocity; v0 = 20 m/s
Initial height; h0 = 60 m
Hence solution can be simplified to determine when the object will hit the ground is; h(t) = -9.8t² + 20t + 60 h(t) = -9.8t² + 20t + 60

What is the value of y in this system of equations?
Negative 6 x + 2 y = negative 18. Negative 3 x minus 2 y = 54.
Answers
Answer:
y = - 21
Step-by-step explanation:
System of equations:
- 6x + 2y = - 18
- 3x - 2y = 54
To find y will look to eliminate x:
- 6x + 2y = - 18
- 3x - 2y = 54 (multiply both sides by -2)
- 6x + 2y = - 18
6x + 4y = - 108
---------------------------- (add those two equations)
6y = - 126 (divide both sides by 6)
y = - 126/6 (simplify by 6)
y = - 21

Answer:

Step-by-step explanation:
In a right triangle, the cosine of one of the acute angles is the ratio of the adjacent ("next to") side to the hypotenuse.
In this triangle, the side adjacent to angle T has length [tex]\sqrt{38}[/tex]. Now you need the length of the hypotenuse, ST. Use the Pythagorean Theorem:
[tex]ST^2=(\sqrt{38})^2+(\sqrt{41})^2 \\\\ST^2=38+41\\\\ST=\sqrt{79}[/tex]
Build the ratio (adjacent) / (hypotenuse) and approximate it with a decimal.
[tex]\cos{T}=\frac{\sqrt{38}}{\sqrt{79}} \approx 0.69[/tex]
[tex]{\large{\red{\mapsto{\maltese{\underline{\green{\boxed{\blue{\underbrace{\overbrace{\pink{\pmb{\bf{Answer:}}}}}}}}}}}}}}[/tex]
To find :-
Cos T = ?
Given :-
Perpendicular(P) = RS = √41
Base(B) = RT = √38
Formula to be used :-
We will use here a trignometry formula to find hypotenuse (H) which is ST.
(hypotenuse)² = (perpendicular)² + (base)²
[tex] \cos(A) = \frac{base}{hypotenuse} [/tex]
Solution:-
H² = P² + B²
H² = (√41)² + (√38)²
H² = 41 + 38
H² = 79
H = √79
[tex] \cos(T) = \frac{B}{H} \\ \cos(T) = \frac{ \sqrt{38} }{ \sqrt{79} } \\ \cos(T) = \frac{6.17}{8.89} \\ \cos(T) = 0.69[/tex]
Result :-
The value of cos(T) is 0.69.
