Write the equation in vertext form

Vertex: (3,6) ; y-intercept: 2

Answers

Answer 1
Answer: Y= a(x-3)^2+6
2= a(0-3)^2+6
2=a(-3)^2+6
2=a(9)+6
2-6=9a
-4=9a
-4/9=a

Therefore the equation in vertex form is
y = -4/9 (x-3)^2+6

Which event has a theoretical probability of exactly Three-fourths? Select three options.

not picking a square

picking a square

picking a triangle

picking a shape that has only straight edges

not picking a circle

Answers

Theoretical probability formula: Favorable Outcomes/All Possible Outcomes

So let's find the theoretical probability for each option.

"Not picking a square"

So, there are 2 squares out of the 8 total shapes (2 circles + 4 triangles + 2 squares) So do 8-2=6... This is subtracting the number of squares out. So we are now left with 6/8.. Reduce the fraction: GCF is 2, so 6/8 simplifies to 3/4. So, "Not picking a square" is an option!

"Picking a square"

Okay so there are 2 squares (favorable outcome) out of 8 shapes in total (all possible outcomes) so the fraction is 2/8. Now simplify: GCF = 2, so 2/8 = 1/4. "Picking a square" is NOT an option

"Picking a triangle"

There are 4 triangles out of 8 shapes, so the fraction is 4/8 which = 1/2. The theoretical probability of picking a triangle is 1/2 and thus NOT an option.

"Picking a shape that has only straight edges"

So this basically means every shape that's not a circle. So, there are 4 triangles + 2 squares = 6 total shapes with straight edges. So there are 6 shapes with straight edges out of 8 total shapes: 6/8 reduces to 3/4. "Picking a shape that has only straight edges" IS an option! :D

LASTLY!

"Not picking a circle"

There are only 2 circles out of 8 total shapes, so 8-2=6 so the fraction is 6/8. This reduces to 3/4. "Not picking a circle" Is an option!

CORRECT ANSWERS:

Not picking a square

Picking a shape that has only straight edges

Not picking a circle

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The correct option is A.

What is a cylinder?

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.

The solid is described as a three-dimensional solid made from

two parallel and congruent discs, not in the same plane, and all the points

between them is a Cylinder.

Hence, the correct option is A.

Tickets to a musical cost $15 for adults and $6 for students. Mr. James and Mrs. Reagan are taking their classes to the musical. If 8 adults, including the teachers, went along as chaperones and the total cost for the combined classes to attend the musical was $480, how many students attended the musical?

Answers

The answer to your question is 9
that is not the answer, the answer is 60 students... what I did was 8x15 to get 120, then I subtracted 480-120 to get 360. 360 is the amount of money the kids cost. Finally I divided 360 by 6 to get 60 because each student was 6$

In the checksums, you validated that the average SAT score for all of the records is 1,059.07. When we work with the data more rigorously, several tests will require us to transform NULL values. If you were to transform the NULL SAT values into 0, what would happen to the average (would it stay the same, decrease, or increase?

Answers

Answer:

It would decrease.

Step-by-step explanation:

The null almost always acts like a placeholder where there is nothing to record for that entry, we can say that it is a dummy character.

The difference between null and zero is that zero has a value in a context whereas null does not have any value.

So given the example in the question, if we replace the null values with zeros, that would affect the average because of the fact that zero values are going to get included in the average, null values were not included. Therefore this will result in the average being decreased.

I hope this answer helps.

For the function f defined above, what is the value of f(-1)

Answers

\bf \underline{ \underline{Given : }}

f(x) =x + 3/2

\bf \underline{ \underline{To \: be \: calculated : }}

what is the value of f(-1) ?

\bf \underline{ \underline{Solution : }}

\sf{f(x) = x + (3)/(2) }

\rightarrow \sf {f( - 1) = ( - 1) + (3)/(2) }

\rightarrow \sf{f( - 1) = ( - 2 + 3)/(2) }

\rightarrow \sf{f( - 1) = ( 1)/(2) }

\rightarrow \sf {f( - 1) = 0.5}

Answer:

0.5

Step-by-step explanation:

Plug in -1 as x into the function:

f(-1) = -1 + 3/2

f(-1) = 0.5
