Answer and  explanation:

Recursive is related to repeat the definition, rule, and procedure.

a) The set of all strings over {a,b} containing at least one a.

Let x is a string containing at least one a: x=a and y= b

Sets of union of XY and yx will be (XY) (yx) = (a,b) (b, a)

b) The set of odd length binary strings that end with 00

There is a regular expression compared with two 00, which is surrounded by 0+1 with at least two 0s.

Answer:

Midpoint = (2,7)

Step-by-step explanation:

Answer: Lin is the most consistent and I would want to have them on my team.

Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since

range = max - min

So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.

Answer:

The coordinates of point B are : (-1, 1)

Step-by-step explanation:

[tex]\frac{-7+x^{2} }{2} = -4\\\frac{1+y^{2} }{2} =1[/tex] You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.

Then you create the equations [tex]-7 + x^{2} = -8\\1 + y^{2} = 2[/tex] you substitute -7 for +7 and add 7 to -8 which gives -1 ([tex]x^{2}[/tex]) and subtract 1 from 2 which gives you 1 ([tex]y^{2}[/tex])

To check your answer use the midpoint formula [tex]\frac{-7+-1}{2} =\frac{-8}{2} =-4\\\frac{1+1}{2} =\frac{2}{2} =1[/tex] which gives you your midpoint (-4,1)

Answer:

x=6

Step-by-step explanation:

1. get the gcf of 3 and 8

3×8=24

2.the new equation would be this:

16/24<3x/24<21/24

3. the value of x would be 6 because 3×6=18.

3×5=15 wouldnt make sense because it is is smaller than 16.

The calculated division of the numbers 7 divided by 9 is 7/9

From the question, we have the following parameters that can be used in our computation:

7 divided by 9

When represented as an equation, we have

7 divided by 9 = 7/9

Divide 48 by 7

So, we have the following result

7 divided by 9 = 7/9

Step-by-step explanation:

Given

It displaces the amount of water equal to its volume

Volume of the sphere:

Correct option is A. 51.0 mL

Answer:

A

Step-by-step explanation:

We are given a diameter of 4.6

4.6 / 2 = 2.3 (radius)

Volume of a sphere [ V = 4/3πr² ]

V = 4/3π(2.3)²

V = 4/3π(5.29)

V = 4/3(38.20438)

V ≈ 51

Answer: The solution would be C

Step-by-step explanation:

If we multiply 40 candy bars by $2.50 we would get the answer of $100 because that is how much she made from selling candy bars. . Then we would have to subtract that answer by $25 because that is how much the box cost. $100 minus $25 is equal to $75. So the answer would be option C

Answer:

10.56÷2.4=4.4

Step-by-step explanation:

Hey there! I'm happy to help!

These are corresponding angles since they both connect a parallel line and the transversal. This means they are congruent and have the same value. So, we can set up the following equation.

8x-8=5x+25

Subtract 5x from both sides.

3x-8=25

Add 8 to both sides.

3x=33

Divide both sides by 3.

x=11.

Have a wonderful day! :D

Answer:

x = 11

∠B = 80

Step-by-step explanation:

∠A = ∠B

where

∠A = 8x - 8°

∠B = 5x + 25°

8x - 8° = 5x + 25°

8x - 5x = 25 + 8

3x = 33

x = 33/3

x = 11

plugin x into ∠B = 5x + 25°

∠B = 5x + 25°

∠B = 5(11) + 25°

∠B = 80

Answer:

412020

Step-by-step explanation:

It is given that,

6.3% of the 6,540,000 Indiana residents were listed as Hispanic or Latino in 2012. We need to find the no of people for this.

Using the concept of percentage as follows :

[tex]\dfrac{6.3}{100}\times 6540000 =412020[/tex]

Hence, there would be 412020 people.

if the car can go 3 miles per hour that means it can go 10 miles in 2 2/3

It takes to go 10 miles 2 2/3 hours.

We have given that,

A toy car can go 3 mph.

We have to determine, How long would it take to go 10 miles.

A mile is a unit of distance equal to 1760 yards or approximately 1.6 kilometers. Meaning, pronunciation, translations, and examples.

If the car can go 3 miles per hour that means it can go 10 miles in 2 2/3.

#SPJ2

Answer:

Entonces la proporción es 1/2

Step-by-step explanation:

Aquí, en esta pregunta, queremos encontrar la razón que divide al segmento AB en la razón (0,5 / 3).

Usamos la fórmula de división interna para esto;

Sea la relación m / n Matemáticamente, la fórmula de división que da lugar a (0,5 / 3) es la siguiente;

(x, y) = mx2 + nx1 / (m + n), my2 + ny1 / (m + n)

En este caso particular;

(x1, y1) = (-2,3)

(x2, y2) = (4, -1)

(x, y) = (0,5 / 3).

Así que hagamos las sustituciones; (0,5 / 3) = m (4) + n (-2) / (m + n), m (-1) + n (3) / (m + n)

(0,5 / 3) = (4m -2n) / (m + n), (-m + 3n) / m + n.

Por tanto, equiparemos términos;

4m-2n / (m + n) = 0

4m -2n = 0

4m = 2n

n = 4 m / 2

n = 2 millones •••••••• (i)

(3n -m) / (m + n) = 5/3

3 (3n -m) = 5 (m + n)

9n - 3m = 5m + 5n

9n -5n = 3m + 5m

4n = 8m

n = 8 m / 4 n = 2m ••••••• (ii)

Podemos ver que ambos son iguales;

n = 2 m 1 = 2m / n

divide ambos lados por 2

m / n = 1/2.

Step-by-step explanation:

A whole number is any number without a decimal. It can also be called an integer.

Answer:

28 feet

Step-by-step explanation:

We know that the perimeter of a square is [tex]2l + 2w[/tex], where l is the length and w is the width.

We also know that the perimeter of a triangle is all of its sides added up.

Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.

Basically:

[tex](3x - 3) + (3x - 3) + (x - 3) + (x - 3) = (2x - 1) + (2x - 1) + (2x)[/tex]

We can combine like terms to get a less scary  equation.

[tex]8x - 12 = 6x - 2[/tex]

Our goal is to now isolate x so we can find it's value.

Add 2 to both sides:

[tex]8x - 10 = 6x[/tex]

Subtract 6x from both sides:

[tex]2x - 10 = 0[/tex]

Add 10 to both sides:

[tex]2x = 10[/tex]

Divide both sides by 2:

[tex]x = 5[/tex]

Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.

Let's do it on the triangle.

[tex]6x-2[/tex] (remember, this is our simplified version of the triangle)

[tex]6(5) - 2\\\\30 - 2\\\\28[/tex]
