The required percent of the people surveyed were satisfied with the car is 50%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

We have,

Total car owner = 2600

People who said to buy car again = 1300

Now

Percentage of satisfied people = [tex]\frac{1300}{2600}[/tex] × 100

Percentage of satisfied people = 50 %

Answer:

When  x =  -16, y = -1.

Step-by-step explanation:

Let's plug in y = -1 into this equation

-1 = 1/4x + 3

Now, we need to solve the equation for x. To do so, we want x to be by itself on one side of the equation. We will use inverse operations to get the x by itself. First, subtract 3 from either side to under the +3 on the right side of the equation.

-1 - 3 = 1/4x + 3 - 3

-4 = 1/4x

Next, we will divide by 1/4 to undo the *1/4. Dividing by 1/4 is the same as multiplying by 4, so we will multiply each side by 4.

-4 * 4 = 1/4x * 4

-16 = x

Answer:

In Euclidean geometry, two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other.

Step-by-step explanation:

The probability that each of the players will have an Ace is 0.1055. The result is obtained by dividing the ways to place Aces for each player by the total ways.

The four suits for a standard deck of 52 cards are hearts, diamonds, clubs, and spades of 13 cards each. The hearts and diamonds are red. While, the clubs and spades are black. The 13 cards are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King.

The 52 cards are randomly distributed to 4 players. So, each players will get 13 cards.

Find the probability that each of them will have an Ace!

When we distribute 13 first cards, the rest cards are 39. After 13 second cards, the rest are 26 cards, an so on. Without discerning the suits, the ways to place Aces so that each player will get an Ace is

n(A) = 13⁴

There are 4 Aces in 53 cards. The total ways to place the Aces is

[tex]n(S) = \binom{52}{4}[/tex]

The probability that each player will have an Ace would be

[tex]P = \frac{n(A)}{n(S)} = \frac{13^{4} }{ \binom{52}{4}} = \frac{28561}{270725} \approx 0.1055[/tex]

Hence, the probability that each player will get an Ace is 0.1055.

Answer: O A. (1.5, 0.75)

Step-by-step explanation: First, take a look at the x-axis. The two line's point of intersection on the x-axis lies between 1 and 2. It's in the middle, so it's 1.5 for the x-axis. We can eliminate answer choices B and C since we've clarified what the correct x-axis value is. Now, the y-axis is a tiny bit tricky but look at the numbers that both lines fall between. It's between 0 and 1 and the point of intersection is almost the value of 1, but not quite. So 0.75 is the y-axis value. Therefore, (1.5, 0.75) is your answer.

To solve for x, the value of x is 40^o.

When two given lines intersect at a point, a series of angles which have common properties called vertical opposite angles are formed.

Two lines are perpendicular if and only if they are at right angle to each other.

To solve for x in the given question, lines AB is perpendicular to CD Let the point of intersection of AB and CD be labelled as O.

Given that: AB ⊥ CD, then;

m<AOD = m<BOC            (vertically opposite angle theorem)

But, m<BOC = 90^o

So that,

(2x + 10) = 90^o

2x = 90 - 10

    = 80

x = 80/ 2

  = 40

x = 40^o

Therefore after solving, it can be deduced that the value of x is 40^o.

The height of the rocket is given by the function y = 30t - 5t^2, where y is in meters and t is in seconds.

What does function mean in maths?

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. The input is commonly called the argument and the output is commonly called the value of the function.

We know that the distance between the observer and the rocket is the square root of the height of the rocket squared plus the distance from the observer to the launch point squared.

r = sqrt(y^2 + d^2)

To find the derivative of r with respect to time, we will use the chain rule.

dr/dt = (dr/dy)(dy/dt)

First, we will find dy/dt. Using the power rule for derivatives, we have:

dy/dt = 30 - 10t

Now, we will find dr/dy. Using the definition of r and the power rule, we have:

dr/dy = 1/sqrt(y^2 + d^2)

Now, we can substitute these values into our original equation for dr/dt:

dr/dt = (1/sqrt(y^2 + d^2))(30 - 10t)

We can now substitute the equation for y into this expression:

dr/dt = (1/sqrt((30t - 5t^2)^2 + d^2))(30 - 10t)

simplifying the above expression

dr/dt = (30t-5t^2)(30-10t)/sqroot(30t-5t^2)^2+d^2

So the expression for the derivative of the distance between the observer and the rocket with respect to time is (30t-5t^2)(30-10t)/sqroot(30t-5t^2)^2+d^2

Here we have the original prices of the rugs are as follows:

Store #1: $289

Store #2: $265

Store #3: $310

Store #1: 20% (decrease)

Store #2: 12%(decrease)

Store #3: 30%(increase)

And the tax details are given as,

Store #1: 8%

Store #2: 8%

Store #3: no tax.

Then the shipping and the handling charges is $5.9

Then the price for each of the store is calculated as,

=> Store 1 = 289 - [(289 x 0.20) + (289 x 0.08) + 5.9] = 202.18

=> Store 2 = 265 - [(265 x 0.12) + (265 x 0.08) + 5.9] = 206.1

If two triangles' corresponding angles and sides are identical and their corresponding sides are proportional, or if the ratios between the lengths of the corresponding sides are comparable, then two triangles are said to be similar.

ABC and A'B'C are similar triangles

Answer:

-6.50

Step-by-step explanation:

The zeros of the function are the x-values that make f(x) equal to zero. To find the zeros of this quadratic function, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Where a = 2, b = 20, and c = 46. Plugging in the values:

x = (-20 ± √(20² - 4 * 2 * 46)) / 2 * 2

x = (-20 ± √(400 - 184)) / 4

x = (-20 ± √216) / 4

x = (-20 ± √6 * √6) / 4

x = (-20 ± 6) / 4

So the zeros are x = (-20 + 6) / 4 = (-14) / 4 = -3.5 and x = (-20 - 6) / 4 = -26 / 4 = -6.5.

Rounding to the nearest hundredth, the zeros are approximately -3.50 and -6.50.

The highest point of the arch is 9/10 feet above the ground.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

To find the highest point of the arch, we need to find the vertex of the parabola defined by the function h = -1/5x²+x.

The vertex of a parabola represented by the equation y = ax² + bx + c is given by

(-b/2a, c-b²/4a)

The vertex of the parabola is given by (-1/2×1/5, h-1/4×1/25) = (1/10, h-1/100)

Now substitute the value of h from the given equation:

h=-1/5x²+x

So, the value of h at the vertex is (1/10, -1/5 × (1/10)²+1/10-1/100) = (1/10, 9/100)

Thus, the highest point of the arch is 9/10 feet above the ground.
