If R is the set of all integers with absolute value less than 10, A is its subset containing all natural numbers less than 10 and B is the set of all integer solutions of inequality 2x+5<9 that are les than 10 by absolute value (and therefore, is also a subset of R), draw Venn diagram showing these sets. List elements of sets A, B, their union, and their intersection.

The coordinates of the midpoint would be (5/2, -3/2) of line segment AB.

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,

M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Coordinates of A are (-2,-7),

Coordinates of B are (7, 4),

M is the midpoint of AB which is given in the question

So the coordinates of M as:

⇒ M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Substitute the values, and we get

⇒ M = ((-2 + 7)/2, ( -7 + 4)/2)

⇒ M = ((5)/2, ( -3)/2)

⇒ M = (5/2, -3/2)

Therefore, the coordinates of the midpoint would be (5/2, -3/2) of line segment AB.

Answer:

The number of seashells collected on day 1 to day 5 is 4, 7, 10, 13 and 16 respectively

Step-by-step explanation:

This is a question that deals with consecutive numbers.

Let x represent the number of seashells collected on her first day.

Given that she collected 3 more each day, then

On day 2, she collected x + 3

On day 3, she collected x + 6

On day 4, she collected x + 9

On day 5, she collected x + 12

Adding up the above will give the number of sea shells collected on day 1;

i.e.

x + x + 3 + x + 6 + x + 9 + x + 12 = 50

Collect like terms

x + x + x + x + x + 3 + 6 + 9 + 12 = 50

5x + 30 = 50

5x = 50 - 30

5x = 20

Multiply ⅕ to both sides

⅕ * 5x = ⅕ * 20

x = 4.

This mean that she found 4 seashells on day 1;

Recall that day 2 = x + 3

So, day 2 = 4 + 3 = 7 seashells

day 3 = x + 6

day 3 = 4 + 6 = 10 seashells

day 4 = x + 9

day 4 = 4 + 9 = 13 seashells

day 5 = x + 12

day 5 = 4 + 13 = 16 seashells

Hence, the number of seashells collected on day 1 to day 5 is 4, 7, 10, 13 and 16 respectively

Answer:

M + $13.72 = $58.22

Step-by-step explanation:

Manny and Sam combined (+) have a total (=) of $58.22

M + S = $58.22

M + $13.72 = $58.22

Answer:

m + $13.72 = $58.22

Step-by-step explanation:

Together they have $58.22.

We know one of them has $13.72, so if we add that to (m) we should get $58.22.

To multiply the monomials (Y⁸)(-2y²), add the exponents and multiply the coefficients resulting in -2y¹⁰.

To multiply the given monomials (Y⁸)(-2y²), we use the laws of exponents which state that when multiplying like bases, we add the exponents. The coefficient -2 multiplies by 1 (the implied coefficient of Y⁸) to remain -2. The new exponent for 'y' is the sum of 8 and 2, which is 10. So, the product in standard form is -2y¹⁰.

Answer:

14.4 in

Step-by-step explanation:

Using the formula of the Pythagorean theorem, a² + b² = c², we can find the length of the missing side.

a = 8

b = 12

c = ?

8² + 12² = 208

To get your answer, you must take the square root of 208.

√208 = 14.4222051

Answer:

The expected value of playing the game is -$7.

Bill should not play this game.

Step-by-step explanation:

The probability distribution of gain and loss is as follows:

  X         P (X)

-$20       0.30

-$40       0.20

$50        0.10

  $5        0.40

Total        1.00

The expected value of a probability distribution is given by:

[tex]E(X)=\sum {X\times P(X)}[/tex]

Compute the expected value of playing the game of chance as follows:

[tex]E(X)=\sum {X\times P(X)}[/tex]

         [tex]=(-\$20\times 0.30)+(-\$40\times 0.20)+(\$50\times 0.10)+($5\times 0.40)\\\\=-\$6-\$8+\$5+\$2\\\\=-\$7[/tex]

The expected value of playing the game is -$7.

The expected value of the game suggests that Bill will incur a loss of $7 if he plays.

So, it is safe not to play the game.

Answer:

y = (4/5)x - 3

Step-by-step explanation:

slope intercept form: y = mx + b

Note the equal sign, what you do to one side, you do to the other. First, subtract 4x from both sides:

4x - 5y = 15

4x (-4x) - 5y = 15 (-4x)

-5y = -4x + 15

Next, divide -5 from both sides:

(-5y)/-5 = (-4x + 15)/-5

y = (-4x + 15)/-5

Simplify Divide -5 from all terms within the parenthesis:

y = (4/5)x - 3

y = (4/5)x - 3 is your answer.

Answer is <

Step-by-step explanation:

To compare the square root of 7 and 14 over 5, we find their approximate values. Since 2.65 (root 7) is less than 2.8 (14/5), the correct mathematical symbol to use is <.

The question asks us to compare two real numbers: the square root of 7 and 14 over 5. First, we need to estimate these numbers. The square root of 7 is approximately 2.65. 14 divided by 5 equals 2.8. Therefore, we can say that 2.65 is less than 2.8. As such, the mathematical symbol that should be used is < which means 'less than'.

Answer:

340

Step-by-step explanation:

Let x = original price

We increase by 25%

x+x*25% = new price

Change to decimal form

x+.25x = new price

Factor out the x

x(1+.25) = new price

x(1.25) = new price

x(1.25) = 425

Divide each side by 1.25

x = 425/1.25

x =340

The original price is 340

Answer:

C. Less than or equal to

Step-by-step explanation:

The floor function is a function used to return an integer value that is great than the input number.

More often than not, the input number is a real number.

Take for instance.

Floor(3.2).

Going by the explanation above, the result of this will be 3

How about floor(-3.2)

The result of this will be -4.

This is so because -4 is less than or equal to -3.2.

The floor function maps any number to the greatest integer that is C.) less than or equal to the number.

The floor function maps any number to the greatest integer that is less than or equal to the number. This means that for any real number \( x \), the floor function, denoted as [tex]\( \lfloor x \rfloor \),[/tex] will produce the largest integer that does not exceed \( x \). For example, \( \lfloor 3.7 \rfloor = 3 \) and \( \lfloor -2.3 \rfloor = -3 \).

The floor function is widely used in mathematics and computer science for rounding down numbers to the nearest integer. It is especially useful in discrete mathematics, algorithms, and number theory. When working with the floor function, it is essential to understand that it always rounds down towards negative infinity, not necessarily towards zero. Thus, for any real number \( x \), \( \lfloor x \rfloor \leq x \).

Therefore, the correct phrase to complete the statement about the floor function is:

C.) less than or equal to.
