Given:
The quadratic equation is
\(y=3x^2-18x+15\)
To find:
The x-coordinate and y-coordinate of the vertex.
Solution:
If a quadratic function is defined by \(f(x)=ax^2+bx+c\), then the vertex is defined as:
\(Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)\)
If \(a<0\), then the function has a maximum at the vertex and ff \(a>0\), then the function has a minimum at the vertex.
We have,
\(y=3x^2-18x+15\)
Here, \(a=3,b=-18,c=15\).
Since \(a=3>0\), therefore the function has a minimum at the vertex. So, fill min in first blank.
Now,
\(\dfrac{-b}{2a}=\dfrac{-(-18)}{2(3)}\)
\(\dfrac{-b}{2a}=\dfrac{18}{6}\)
\(\dfrac{-b}{2a}=3\)
Putting x=3 in the given function, we get
\(y=3(3)^2-18(3)+15\)
\(y=27-54+15\)
\(y=-12\)
Therefore, the vertex is at point (3,-12).

raise the product of 36 and 9 to the power of the sum of 2 and 4
Answer:
1.15683 1381 * 10^15
Step-by-step explanation:
To get the answer, first, get the product of 36 and 9
This can be obtained by multiplying 36 with 9
36 * 9 = 324
We then raise 324 to the power of the sum of 2 and 4
The sum of 2 and 4 is gotten by adding 2 to 4
So,
2 + 4=6
Therefore, 324 raised to the power of 6
= 1.15683 1381 * 10^15
The table and corresponding image show the proof of the relationship
between the slopes of two parallel lines. What is the missing statement in
step 4?
A. c-d=b-a
B. b-c=d-a
OC. c-0=a-b
OD. d-0=8-a
Option A. c - 0 = b - a is the missing statement in Step 4 of the proof.
To determine the missing statement in Step 4 of the proof, let's examine the given table and image related to the relationship between the slopes of two parallel lines.
Step 1: Given the slopes of two parallel lines, m₁ and m₂.
Step 2: Assume two points on each line: (0, a) and (c, b).
Step 3: Calculate the slopes using the slope formula: m₁ = (b - a) / (c - 0) and m₂ = (d - a) / (0 - c).
Step 4: ??? (Missing Statement)
Step 5: Since the lines are parallel, the slopes are equal, so m₁ = m₂.
By analyzing the given information, we can identify the missing statement by comparing the calculated slopes:
From Step 3, we have:
m₁ = (b - a) / (c - 0)
m₂ = (d - a) / (0 - c)
Comparing the two slopes, we can see that (b - a) / (c - 0) = (d - a) / (0 - c).
To express this relationship, the missing statement in Step 4 should be:
A. c - 0 = b - a

Answer:
Step-by-step explanation:
1a) the y intercept, or 20
b) from 0 weeks to 1 week the difference is 10
c) its y=mx+b m is the slope(difference) and b is the y-int so y = 10x+20
2a) the y int, is the same as the x(number of games played) being zero, so here it is 25
2b) after 3 games it was a loss of 1.50 !!! IMPORTANT !! after THREE weeks, so its 1.5/3=0.5 amount on card per week

Question 1 of 20:
Select the best answer for the question.
1. Will bought 3 college textbooks. One cost $32, one cost $45, and one cost $39.
What is the average price of his books? Choose the statement that correctly
calculates the average.
A. $32 + $45 + $39 : 3
B. $32 : 3 + $45 : 3 + $39
O C.3 × $32 + $45 + $39
D. ($32 + $45 + $39) = 3
Mark for review (Will be highlighted on the review page)
Next Question >>
Answer:
I would have to say A) 32 + 45 + 39: 3
Step-by-step explanation:
This is because when finding the average of literally anything, you want to add up all the numbers, and then divide the sum of it by the numbers you added up.
for instance: 32 + 45 + 39 = 116. now, we need to divide by 3 because we added 3 numbers up.
116 divided by 3 = x
x is our average cost per books.
hope this helped, gl on your test!! :')

suppose a random sample of 40 houses are selected from the city. estimate the probability that the mean value of the 40 houses is less than $500,000 . show your work
a. Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71
b. the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
a. The mean of the distribution is given as $403,000 and the standard deviation is $278,000.
To estimate the probability that a randomly selected house has a value less than $500,000:
P( x < 500,000)=P(x=0)+P(x=500)
=0.34+0.37+
=0.71
Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71
b. -since 40 is larger than or equal to 30, we assume a normal distribution.
-The probability can therefore be calculated as:
P(x')=P( z < (x' -u)/σ.sqrt(n)))
P(z< (500-403)/(578sqrt(40)))
=P(z<2.2068)
=0.986336
Hence, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
The complete question is -
a) Suppose one house from the city will be selected at random. Use the histogram to estimate the probability that the selected house is valued at less than $500,000. Show your work.
(b) Suppose a random sample of 40 houses are selected from the city. Estimate the probability that the mean value of the 40 houses is less than $500,000. Show your work.

What meaning of the statement this: subgroups partition groups into subsets of equal size?
Answer:
This statement means that subgroups divide a larger group into smaller groups, and each of these smaller groups has the same number of things in it. For example, if there are 12 people in a group, and they form subgroups of 3 people each in a group, there will be 4 groups total, and each individual subgroup will have 3 people in it.

Which value of m makes this equation true? m - 8 = -1
m = 9
m=7
m= -9
m = -7
Answer:
The answer is 7 because if we write 7 - 8 = -1, then we could see that the answer would be -1 since 7 is 1 value lower than 8, and 8 - 8 = 0, so if 7 is lower than 8 by 1, then you would go one value lower from 0, which is -1. You can also figure this out by looking at a number line and starting from 7 and then going backwards 8 times and whatever number you land on after going back 8 times is your answer.

Suppose that the sample size had been 4500 rather than 1033. Find the margin of error for 95% confidence for the larger sample Give your answer to three decimal places. margin of error:
The formula for calculating margin of error is expressed as
\(\text{margin of error = z }\times\text{ (}\sqrt[]{\frac{pq}{n}})\)Where
p represents the probability of success
q represents the probability of failure
n represents sample size
z represents the z score for a 95% confidence interval
From the information given,
p = 30% = 30/100 = 0.3
q = 1 - p = 1 - 0.3 = 0.7
n = 4500
From the standard normal distribution table, z = 1.96
By substituting these values into the formula, we have
\(\text{margin of error = 1.96}\times\sqrt[]{\frac{0.3\times0.7}{4500}}\text{ = }0.013\)margin of error = 0.013

Answer:
\(x=29^{\circ}\)
Step-by-step explanation:
Please refer to the picture attached as I labeled the angles.
Given
\(\angle{B}=90^{\circ}\)
\(\angle{ADB}=58^{\circ}\)
\(AD=CD\)
\(\angle{ACD}=\angle{CAD}\) which also equals x in your picture.
We need to use the Exterior Angle Property to evaluate x.
This property states that the exterior angle equals sum of two interior opposite angles.
\(\angle{ACD}+\angle{CAD}=58^{\circ}\)
Substitute x for \(\angle{ACD}\) and \(\angle{CAD}\).
\(x+x=58^{\circ}\)
Add x and x.
\(2x=58^{\circ}\)
\(x=29^{\circ}\)
Answer:
The angle is 32
Step-by-step explanation:
The formula for the sum of interior angles is \((n-2)180\)
We have a triangle inside a triangle.
A triangle has 3 sides.
\((n-2)180\\(3-2)180\\1(180)\\180\)
The picture shows us an angle of 90 and 58.
All 3 angles must add up to 180.
\(180-90-58\)
\(x=32\)

Answer:
300.5
Step-by-step explanation:
Firstly, you must remember PEMDAS. This formula shows what order to do which parts of the equation!
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
The parenthesis mean that we must do the two equations in them separately.
So, first do 3 x 10². Next, do 5 x 1/10. Finally, add the two products together!
3 x 10² = 300
5 x 1/10 = 0.5
