Step-by-step explanation:

In linear equation, The number of customers who will pay by debit card will be 44.

Which equation is linear?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                     Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

16 + 33 + 6 = 55 customers.

That means that the fraction of the customers, who paid by debit card, was

6/55  

In situations like that, when we use historical data and try to predict future behaviour, we use that past experience and extrapolate to a predicted result.

we simply say that we expect the same fraction, 1/30 if customers use credit cards.

for the absolute number of predicted debit  card customers we multiply the predicted number of customers by the expected fraction

400  × 6/55 = 2400  /55  = 43.63 ≈ 44

Therefore the number of customers who will pay by debit card will be 44.

Answer:

C. x=2 ± √13

Explanation:

Answer:

Step-by-step explanation:

Plug in 6 for x for g(x) and f(x)

f(6) = 2(6)⁵ = 15,552

g(6) = 10 x 4⁶ = 40,960

15,552 < 40,960

f(6) < g(6)

The vertex form of Parabola is y= 1/4(x + 2)² -4 .

The general equation of a parabola is given by y = a(x – h)² + k or

x = a(y – k)² +h. Here (h, k) is vertex.

Given:

focus at (–2,–3) and a directrix at y = –5.

We know, the standard form is (x - h)² = 4p (y - k),

where the focus is (h, k + p) and the directrix is y = k - p

So, (h, k + p) = (-2, -3)

h = -2, k + p = -3

Directrix is y = k - p:

k - p = -5

k + p = -3

so, 2k = -8

k = -4

and, p = -3+ 4 = 1

Thus, the vertex is at (-2, -4) and p = 1, the equation is:

(x + 2)² = 4(y+  4)

1/4(x + 2)² =  y+4

y= 1/4(x + 2)² -4

Okay, let's break this down step-by-step:

   The initial point is P(-4, 5)

   The terminal point is Q(-2, 7)

To find the components of the vector V, we need to determine:

   The change in x-coordinate = -4 - (-2) = -2

   The change in y-coordinate = 5 - 7 = -2

So the vector components are:

<change in x-coordinate, change in y-coordinate>

= <-2, -2>

Therefore, the answer is choice (i): < -2,-2>

The other choices do not represent the correct changes between the given points P and Q.

Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90 degree angle).

x² = 12² + 9² = 144 + 81 = 225

x = 15 ft

so, the first answer option is correct.

The value of hypotenuse (x) in the right angled triangle is 15ft.

Given,

Right angled triangle .

Here,

Pythagoras theorem,

c² = a² + b²

here,

c = hypotenuse

a = perpendicular

b = base

Substitute the values in the formula,

x² = 12² + 9²

x² = 144 + 81

x² = 225

x = 15 ft

Thus the length of hypotenuse is 15ft .

So, option A is correct.

The total distance from Duncan's start on the diving board to his lowest point beneath the surface of the pool will be 12 feet.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Duncan is excited to begin diving lessons. He starts on the diving board, 5 feet above the surface of the pool. Then, Duncan dives off the board and ends up 7 feet below the surface of the pool.

Distance = 7 + 5
Distance = 12 feet

Therefore, the total distance from Duncan's start on the diving board to his lowest point beneath the surface of the pool will be 12 feet.

Answer:

\(\boxed {x = -1}\)

Step-by-step explanation:

Solve for the value of \(x\):

\(15 + 3x = 3(2 - 2x)\)

-Use Distributive Property:

\(15 + 3x = 3(2 - 2x)\)

\(15 + 3x = 6 - 6x\)

-Take \(6x\) and add it to \(3x\):

\(15 + 3x + 6x = 6 + 6x - 6x\)

\(15 + 9x = 6\)

-Subtract both sides by \(15\):

\(15 - 15 + 9x = 6 - 15\)

\(9x = -9\)

-Divide both sides by \(9\):

\(\frac{9x}{9} = \frac{-9}{9}\)

\(\boxed {x = -1}\)

Therefore, the value of \(x\) is \(-1\).

a) Expected value of x = 2.82

b) Variance of x = 4.4732

c) Standard deviation for x = 2.1145

To find the expected value of x, we need to multiply each value of x by its corresponding probability and then sum the results

E(x) = (0)(1) + (1)(0.15) + (2)(0.13) + (3)(0.07) + (4)(0.55)

= 0 + 0.15 + 0.26 + 0.21 + 2.2

= 2.82

Therefore, the expected value of x is 2.82.

To find the variance of x, we need to first find the squared deviations of each value of x from the expected value

(0 - 2.82)^2(1) + (1 - 2.82)^2(0.15) + (2 - 2.82)^2(0.13) + (3 - 2.82)^2(0.07) + (4 - 2.82)^2(0.55)

= 8.4961

Then, we can calculate the variance as the weighted average of these squared deviations, using the probabilities as weights

Var(x) = 8.4961/1.9

= 4.4732

Therefore, the variance of x is 4.4732.

Finally, the standard deviation of x is the square root of the variance

SD(x) = sqrt(4.4732)

= 2.1145

Step-by-step explanation:

The length of the apothem of the regular pentagon shown is 5.2 meters

Represent the central angle of the regular pentagon using x

The value of the central angle of the regular pentagon is then calculated as:

x = 360/n

Where n represents the number of sides

i.e n = 5

So, we have:

x = 360/5

Evaluate the quotient

x = 72

Represents the apothem with y.

The apothem is then calculated as:

tan(x/2) = (Side length/2)/Apothem

This gives

tan(72/2) = (7.6/2)/y

Evaluate the quotient

tan(36) =3.8/y

Multiply both sides by y

y tan(36) = 3.8

Divide both sides by tan(36)

y = 3.8/tan(36)

Evaluate the quotient

y = 5.2

Hence, the length of the apothem of the regular pentagon shown is 5.2 meters

In this case, we would like to model this situation as an inequality.

It says that, in order to ride the roller coaster, you should at least be 48 inches tall. So, when someone wants to ride the roller coaster, his/her height should be greater or equal to 48 inches. This situation can be modeled witht the inequality

where y is the height of the person at the moment he/she is trying to ride the roller coaster.

Right now, Michale es 42 inches tall. So he is not able to ride the roller coaster yet.

We are told that he grows 1/2 inch every month. Let x be the months that have passed since we was 42 inches. So, the total amount he grew is

After he grew this amount, he will be as tall as the sum of this two quantities, namely,

Since we want that Michael should be able to ride the roller coaster, his height should be above the given limit, so we get the inequality

now, we want to solve this inequality for x. To do so, we subtract 42 on both sides, so we get

Now, we multiply by 2 on both sides, so we get
