Answer:

should be B.

Step-by-step explanation:

When it has a underline it usually means that its a solid circle.

Answer:

Step-by-step explanation:

For this problem, imagine the standard form, which is:

f(x) = ax² + bx + c = y

Using the table, and adding that y at the end, we can plug in and write out the following equations. (Writing it out is important):

f(-1) = a(-1)² + b(-1) + c = 14

f(0) = a(0)² + b(0) + c = 7

f(1) = a(1)² + b(1) + c = 4

f(2) = a(2)² + b(2) + c = 5

Now if this doesn't look familiar, it's actually a systems of equations using the a, b, and c elements as your three variables! If you simplify the equations:

f(-1) = a - b + c = 14

f(0) = c = 7

f(1) = a + b + c = 4

f(2) = 4a + 2b + c = 5

Something unique just happened. We have already defined what ' c ' is!

c = 7

Setting that aside, if you remove the f(x) portion of the equations, you're left with:

a - b + c = 14

a + b + c = 4

4a + 2b + c = 5

Using the two upper equations, if we add them together (you can do that as it doesn't change the values of the variables) you get:

2a + 2c = 18

Note: the ' b ' variables cancelled out in the addition [ b +  (-b) ]

If you further simplify the equation:

a + c = 9

Awesome. Now we already know that c = 7, so if you plug that into the equation:

a + 7 = 9

Solve for a. So then a = 2

Now that we know the following:

a = 2

c = 7

We can then use the equation:

a + b + c = 4

And solve for b!

2 + b + 7 = 4

Simplify.

b + 9 = 4

Simplify.

b = -5

Now at this point, since you know what a, b and c are, you can write the equation!

f(x) = 2x² - 5x + 7

You can confirm your work by putting any of the x values in the table through!

Answer:

Step-by-step explanation:

You do 5625 / 25 like this: For each step you multiply 25 by the highest number possible in the first 2 numbers. So if it was 27 / 9  you would find how many times 9 can fit into 27 but since the number 5625 is not one of the first 10 multiples of 25 you see the first 2 numbers and if you still can't divide you combine the next value. The top number is the answer.

Answer:

2/15

Step-by-step explanation:

Reduce the expression, if possible, by cancelling the common factors.

The equivalent value of the fraction is A = 2/15

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = p/q

when the value of p = 2/5

And , when the value of q = 3

On simplifying the equation , we get

A = ( 2/5 ) / 3

So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) / 3

A = ( 2/5 ) / 3

A = ( 2/5 ) ( 1/3 )

On simplifying , we get

A = 2/15

A = 0.133333

Therefore , the value of A = 2/15 = 0.133333

Hence , the fraction is A = 2/15

Answer:

-6c + 7

Step-by-step explanation:

(This question probably requires bodmas)

9c + 3 = 9c + 3

9c + 3 + 13c = 22c + 3

22c + 3 - 4c = 18c + 3

18c + 3 + 4 = 18c + 7

18c + 7 - 24c = -6c + 7

Answer:

9/64

Step-by-step explanation:

Take half of the x-term coefficient and square it.

x^2 + 3/4 x

The x-term coefficient is 3/4.

Half of 3/4 is 3/8.

Now square 3/8 to get 9/64.

Answer:

1/12

Step-by-step explanation:

Given the following mathematical expression;

[tex]\frac{\frac{1}{3}}{4}[/tex]

We would apply the law of indices for fractions.

1/3/(4) = 1/3 * 1/4 = 1/12

The solution is : 1/3 divided by 4 is 1/12.

Here, we have,

given that,

1/3 divided by 4

Given the following mathematical expression;

1/3 /  4

We would apply the law of indices for fractions.

1/3/(4)

= 1/3 * 1/4

=1/ 3*4

= 1/12

Hence, The solution is : 1/3 divided by 4 is 1/12.

Answer:

The interquartile range is also known as midspread and it is the between the first and third quartile (25th and 75th percentile respectively) serving as a robust measure of sample dispersion.

Interquartile range (IQR) = Q3 - Q1

As a measure of variability, it is based on splitting data sets into quartile (four equal portions). The values differentiating these portions are known as the first, second, and third quartile which are represented as Q1, Q2, and Q3, respectively.

Answer:

1/12

Step-by-step explanation:

first we have to find all the possibilities of getting a sum of 3 or less: 1+1 or 1+2 and we count the second combination 2 times because the numbers can be on either of the dices so we have a total of 3 possibilities. all the possible pairimg of dice are 6*6=36 because each dice has 6 sides and we can get either of them. so the probability would be the chance of getting a sum of 3 or less divided by all the diff combination which equals 3/36 or 1/12 which is roughly around 8.3%
