Answer:

Nguyen family uses sprinkler for 35 hours while the Hall family uses sprinkler for 15 hours

Step-by-step explanation:

Let h and n be the number of hours that the Hall and Nguyen family individually use their sprinkler for, respectively. Since they use for a combined total of 50 hours, h + n = 50, or h = 50 - n

Also their total water output is 1050 L, we can have the following equation

35h + 15n = 1050

Substitute h = 50 - n and we have

35(50 - n) + 15n = 1050

1750 - 35n + 15n = 1050

35n - 15n = 1750 - 1050

20n = 700

n = 35 hours

h = 50 - n = 50 - 35 = 15 hours

Option C) [tex]{\{0.5,0}\}[/tex] is correct

The solution to the given equation is [tex]{\{0.5,0}\}[/tex]

Step-by-step explanation:

Given quadratic equation is [tex]-2x^2+x=0[/tex]

To solve the equation by completing the square :

[tex]-2x^2+x=0[/tex]

[tex]-2(x^2-\frac{x}{2})=0[/tex]

[tex]x^2-\frac{x}{2}=0[/tex]

Rewritting the above equation as below :

[tex]x^2-2(x)\frac{1}{4}+\frac{1}{4^2}-\frac{1}{4^2}=0[/tex]

[tex](x-\frac{1}{4})^2-\frac{1}{4^2}=0[/tex]

[tex](x-\frac{1}{4})^2=\frac{1}{4^2}[/tex]

Taking square root on both sides we get

[tex]\sqrt{(x-\frac{1}{4})^2}=\sqrt{\frac{1}{4^2}}[/tex]

[tex](x-\frac{1}{4})=\pm\frac{1}{4}[/tex]

[tex]x=\pm\frac{1}{4}+\frac{1}{4}[/tex]

[tex]x=+\frac{1}{4}+\frac{1}{4}[/tex] and [tex]x=-\frac{1}{4}+\frac{1}{4}[/tex]

[tex]x=\frac{2}{4}[/tex] and [tex]x=0[/tex]

Therefore [tex]x=\frac{1}{2}[/tex] and x=0

[tex]x=0.5[/tex] and x=0

Therefore the solution to the given equation is [tex]{\{0.5,0}\}[/tex]

Option C) [tex]{\{0.5,0}\}[/tex] is correct

Answer:

The answer to your question

a) Values excluded = -2, 0

b) solutions = -2/3, 2

Step-by-step explanation:

Equation

                        [tex]\frac{4x}{2x + 4} = \frac{x+ 2}{2x}[/tex]

a) x is restricted when the denominators equal zero, so let's get them.

                 2x + 4 = 0                           2x =  0

                 2x = - 4                                  x = 0 / 2

                 x = -4 / 2                               x = 0

                 x = -2

x must be different to -2, 0

b)                   [tex]\frac{4x}{2x + 4} = \frac{x+ 2}{2x}[/tex]

                      [tex]\frac{2x}{x + 2} = \frac{x + 2}{2x}[/tex]

                      4x² = (x + 2)²

                      4x² = x² + 4x + 4

                     4x² - x² - 4x - 4 = 0

                      3x² - 4x - 4 = 0

                      3x² - 6x + 2x - 4 = 0

                     3x(x - 2) + 2(x - 2) = 0

                     (x - 2)(3x + 2) = 0

                      x₁ - 2 = 0                  3x₂ + 2 = 0

                     x₁ = 2                         x₂ = -2/3

Answer: P(Upper E' prime) = 0.06

P(Upper E' prime) + P(Upper E' prime) = 1

Therefore

P(Upper E' prime) + 0.94= 1

P(Upper E' prime) =1- 0.94

P(Upper E' prime) = 0.06

Answer:

the top of the ladder is 27.5ft above the ground.

Step-by-step explanation:

The ladder makes an angle, θ with the ground thus forming a right angle triangle with the wall of the house.

The length of the ladder represents the hypotenuse of the right angle triangle.

The ground distance from the base of the wall to the foot of the ladder represents the adjacent side of the right angle triangle.

Therefore, to determine how high up is the top of the ladder on the wall, x, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

28² = x² + 5²

784 = x² + 25

x² = 784 - 25 = 759

x = √759 = 27.5ft

Using the Pythagorean theorem, the ladder reaches approximately 27.5 feet up the wall when the base is 5 feet from the wall.

The question involves finding the height up a wall that a 28ft ladder reaches when its base is 5ft from the wall. To solve this, we will use the Pythagorean theorem which relates the sides of a right-angled triangle. The ladder, wall, and ground form a right-angled triangle with the ladder as the hypotenuse and the wall and ground as the other two sides.

Let h be the height the ladder reaches up the wall. Using the Pythagorean theorem, we have:

28² = h² + 5²

Solving for h:

28² - 5² = h²


784 - 25 = h²

759 = h²

h ≈ √759

h ≈ 27.5 (to the nearest tenth)

Therefore, the ladder reaches approximately 27.5 feet up the wall.

The value of x in the expression will be 36.

The correct answer is option D. 36.

We need to solve the equation:

√(x - 11) = 5

To solve this, follow these steps:

Square both sides to eliminate the square root.

√(x - 11)2 = 52

x - 11 = 25

Isolate x by adding 11 to both sides:

x - 11 + 11 = 25 + 11

x = 36

So, the correct answer is 36 (option D).

Answer:x = 9.01

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle the hypotenuse of the right angle triangle is 17

With 35 degrees as the reference angle,

x represents the adjacent side of the right angle triangle.

The unlabelled side represents the opposite side of the right angle triangle.

θ = 35 degrees

To determine x, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos 35 = x/11

x = 11 Cos 35 = 11 × 0.8192

x = 9.01

Answer:

9.01

Step-by-step explanation:

The right angle triangle with a focused angle of degree is easily solved using Trig Ratio that can easily be recalled with this word :

SohCahToa.

What it means is:

If the Opposite side to the focused angle is given and also the hypotenuse is given, we use sine

Cosine if Adjacent and Hypotenuse is given.

Tangent if the opposite and Adjacent is given.

Now, to the question:

The Adjacent and the Hypotenuse is given. Therefore we'll use Cosine.

Therefore:

Cos 35 = x / 11

Cross multiplying:

11 cos 35 = x

11 * 0.8192 = x

Theresfore,

x = 9.01

Answer: Option 'e' is correct.

Step-by-step explanation:

Since we know that

Discrete data are those data which is countable and it is expressed in exact numerical form.

Continuous data are those data which is lie within the interval and it varies so it does not expressed in exact numerical form.

Here, the number of iphones sold today at an Apple store is countable and it can be expressed in exact numbers.

So, it is considered as discrete.

Hence, Option 'e' is correct.

Final answer:

The number of iPhones sold today at an Apple store represents an example of quantitative discrete data.

Explanation:

The number of iPhones sold today at an Apple store is an example of classified as discrete data. This is because the number of iPhones can only take on specific numerical values and cannot be a fraction or a decimal. In other words, you cannot sell half an iPhone, so the data is quantitative discrete.

Final answer:

The statement forms p → q ∨ r, p ∧ ¬q → r, and p ∧ ¬r → q are shown to be logically equivalent using principles of logical equivalence and contraposition. The original statement 'If n is prime, then n is odd or n is 2' can thus be rephrased in different ways while retaining the same meaning.

Explanation:

Logical Equivalences

To show that the statement forms p → q ∨ r, p ∧ ¬q → r, and p ∧ ¬r → q are all logically equivalent, we need to understand that logical equivalence means that the statements have the same truth value in every possible scenario. The implication p → q is equivalent to p∨ q, as a truth table would confirm. Likewise, by using the principle of contraposition, which states that p → q is equivalent to ¬q → ¬p, we can transform the given implications accordingly.

Considering the sentence "If n is prime, then n is odd or n is 2" and denoting p as "n is prime", q as "n is odd", and r as "n is 2", the original statement can be represented as p → q ∨ r. Using logical equivalences established earlier, two different ways to rewrite this sentence could be:

The logical equivalences show that all these forms express the same condition from different perspectives but with the same meaning.

The function f(x) = -9x³ + 8x is odd.

Option A is the correct  answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

A function f(x) is even if f(-x) = f(x).

A function is odd if f(-x) = -f(x).

Using the above definition.

f(x) = -9x³ + 8x

Put x = -x

f(-x) = -9 x (-x³) + 8 x (-x)

f(-x) = 9x³ - 8x

f(-x) = - ( -9x³ + 8x)

f(-x) = -f(x)

This means,

The function is odd.

Thus,

f(x) is odd.
