A group of employees were asked whether they drive or walk to work.

Hence ,the basketball team  scored 83 points in  the first game.

Basketball is a team sport in which two teams,  most commonly of five players each,  opposing one another on a rectangular court,  compete with the primary objective of shooting a basketball through the defender's hoop,  while preventing the opposing team from shooting through their own hoop.

A team is a group of individuals (human or non-human) working together to achieve their goal.As defined by Professor Leigh Thompson of the Kellogg School of Management, team is a group of people who are interdependent with respect to information, resources, knowledge and skills and who seek to combine their efforts to achieve a common goal

Let x be  the number of points  scored in the first game.

According  to the  question,

747 = 9 x

now  9 divided by both sides,

x = [tex]\frac{747}{9}[/tex]

than we get:

x = 83

Therefore,  the basketball team  scored 83 points in  the first game.

The conclusion of the given hypothesis is: we FAIL to reject the null hypothesis and conclude that there is not enough evidence to reject the claim that the mean lifetime of the newest model is 12 years

The parameters given are:

Population mean: μ = 12

Sample mean: x' = 12.5

Population standard deviation; σ = 3.5

Sample size: n = 35

Let's define the hypotheses:

Null Hypothesis: H₀: μ = 12

Alternative Hypothesis: Hₐ: μ ≠ 12

Let us find the z-score from the formula:

z = (x' - μ)/(σ/√n)

z = (12.5 - 12)/(3.5/√35)

z = 0.845

The p-value from online p-value from z-score calculator using two tailed hypothesis and a significance level of 0.1 gives:

p-value = 0.398

The p-value is greater than the significance value and we FAIL to reject the null hypothesis and conclude that there is not enough evidence to reject the claim that the mean lifetime of the newest model is 12 years

The angle that is vertical to angle DEB is A.

A vertical angle is an angle formed by two intersecting lines or planes that are perpendicular to each other. Specifically, it is the angle between two straight lines or planes that intersect each other and are perpendicular to the horizontal plane.

The measure of a vertical angle is always the same as the measure of the other vertical angle formed by the same two intersecting lines or planes. This is because vertical angles are always congruent, meaning they have the same size and shape. Vertical angles are commonly used in geometry and trigonometry to solve problems involving angles, lines, and plane.

We are given the system of equations:

y = 3x

y = 6x + 3

We can use substitution to solve this system. Since both equations are equal to y, we can set them equal to each other:

3x = 6x + 3

Subtracting 3x from both sides, we get:

0 = 3x + 3

Subtracting 3 from both sides, we get:

-3 = 3x

Dividing both sides by 3, we get:

x = -1

Now that we know x, we can use either equation to find y. Let's use the first equation:

y = 3x = 3(-1) = -3

Therefore, the solution to the system of equations is (-1, -3).

To check our solution, we can substitute these values back into both equations:

y = 3x gives us -3 = 3(-1), which is true

y = 6x + 3 gives us -3 = 6(-1) + 3, which is also true

Therefore, our solution is correct.

We can also plug in the other given points to check that they do not satisfy both equations, which means they are not solutions to the system.

The area the grass seed needs to cover is 7,425 square meters.

To find the total area of the lawn excluding the pool, we first need to calculate the area of the pool. Using the formula for the area of a rectangle, we multiply the length and width of the pool together to get:

= 7.5 m x 3.25 m

= 24.375 square meters

Next, we can find the total area of the lawn by subtracting the area of the pool from the total area of the rectangle formed by the lawn:

= 50 m x 150 m

= 7,500 square meters

So, the area the grass seed needs to cover is:

= 7,500 square meters - 24.375 square meters

= 7,425 square meters.

Answer:5,4

Step-by-step explanation:

there are 133,784,560 ways to draw 7 cards from a standard deck of 52 cards.

How to solve the question?

The number of ways to draw 7 cards from a standard deck of 52 cards can be calculated using the combination formula, which is:

C(52, 7) = 52! / (7! * (52-7)!)

where "!" represents the factorial function.

To simplify this expression, we can use the property that n! / k! = n * (n-1) * (n-2) * ... * (n-k+1) for positive integers n and k such that k ≤ n.

Using this property, we can rewrite the above expression as:

C(52, 7) = (52 * 51 * 50 * 49 * 48 * 47 * 46) / (7 * 6 * 5 * 4 * 3 * 2 * 1)

Simplifying this expression, we get:

C(52, 7) = 133,784,560

Therefore, there are 133,784,560 ways to draw 7 cards from a standard deck of 52 cards.

To understand why this is the case, we can think of each draw as a separate event with no replacement. The first card can be drawn in 52 ways, the second card can be drawn in 51 ways (since one card has already been drawn), the third card can be drawn in 50 ways (since two cards have already been drawn), and so on. Therefore, the total number of ways to draw 7 cards is the product of the number of ways to draw each individual card, which is 52 * 51 * 50 * 49 * 48 * 47 * 46. However, since the order in which the cards are drawn does not matter, we need to divide by the number of ways to arrange 7 cards, which is 7 * 6 * 5 * 4 * 3 * 2 * 1 (i.e., 7 factorial). This gives us the final answer of 133,784,560.

Answer: Correct answer is pie/2 or A

Step-by-step explanation:

r = -5sinθ + 4θ has symmetry with respect to the line θ = π/2.

To demonstrate this, we can apply the third symmetry test for polar equations:

Symmetry with respect to the line θ = π/2: Replace θ by π - θ and see if the equation remains the same. If it does, the equation has symmetry with respect to the line θ = π/2.

r = -5sin(π/2 - θ) + 4(π/2 - θ) = 5cosθ + 2π - 4θ

r = 5cosθ + 2π - 4θ is the same as the original equation, so there is symmetry with respect to the line θ = π/2.

Therefore, the correct answer is θ = π/2.

b. In the year 2015, the number of cell phone subscribers were about 7 billion.

The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

Any real number may be explained using the four basic operations, also referred to as "arithmetic operations." In mathematics, operations like division, multiplication, addition, and subtraction come before operations like quotient, product, sum, and difference.

a. Since, during next 5 years there is increase by 4% so, we get the base using the addition operation as:

1 + 4% = 1.04

The exponential model comes out to be

y = 6.26 * [tex]1.04^{t}[/tex]

Now, the number of cell phone subscribers in 2016 is:

y = 6.26 * [tex]1.04^{4}[/tex]      (This is because t = 4)

y = 7.32 billion

b. We are given y = 7 billion.

So, we get

⇒ 7 = 6.26 * [tex]1.04^{t}[/tex]

⇒ 1.12 = [tex]1.04^{t}[/tex]                           (Using the division operation)

⇒ t = 2.8

So, in 2015, the number of cell phone subscribers were about 7 billion.

For the function f(x) = √x+2+5:

(D) D= {x|x≥2}, R= {y|y≥5}

The domain is restricted to x values greater than or equal to 2 because the function contains the square root of x+2, which cannot be negative. The range starts at y = 5 because the lowest possible output of the function is √2+2+5 = 5.

(A) f(x)+∞o as x→ +∞o; f(x) +∞ as x――∞

As x approaches positive infinity, the output of the function approaches infinity as well. As x approaches negative infinity, the function is undefined since it involves taking the square root of negative numbers. However, the limit of the function as x approaches negative infinity from the right is positive infinity.
