Write a function to represent the number of patients she sees, , and the number of hours, , the hygienist works after lunch on Monday.

An equation to represent the total cost of a job that takes "x" hours is "total cost = $50 + ($150 × x)". The situation can be described as linear.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the cost of consulting is $50, while the cost of labour is $150 per hour.

A.) An equation to represent the total cost of a job that takes "x" hours.

Total cost = $50 + ($150 × x)

B.) Total cost is the labour works for 40 hours,

Total cost = $50 + ($150 × 40) = $6,050

C.) As found above the cost of working 40 hours is $6,050, therefore, the amount of $5,000 will not be enough.

D.) The situation can be described as linear.

Answer:

8/5x

Step-by-step explanation:

it's (-4,-4) and (1,4) so you subtract the y's getting 8. then you subtract the x's getting 5. y/x is the rule so you would get 8/5 or 8/5x as the slope/distance between points.

Answer:

cos 90°

Step-by-step explanation:

(cos 60°)(cos 30°) − (sin 60°)(sin 30°)

= cos ( 60° + 30°)

= cos 90°

The expression (cos 60°) (cos 30°) − (sin 60°) (sin 30°) is cos 30°.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

(cos 60°)(cos 30°) − (sin 60°)(sin 30°)

We can use the trigonometric identity for the difference of angles between cosines.

cos(x - y) = cos(x)cos(y) - sin(x)sin(y)

By setting x = 60° and y = 30°.

So,

cos(60° - 30°) = (cos 60°)(cos 30°) − (sin 60°)(sin 30°)

cos 30° = (cos 60°) (cos 30°) − (sin 60°) (sin 30°)

Thus,

(cos 60°) (cos 30°) − (sin 60°) (sin 30°) is cos 30°.

Answer:

12 ÷ (7-4) + 5 × 3 = 19

Step-by-step explanation:

The surface area of the pyramid is 96 ft²

The surface area of the square base prism is 552 ft²

The surface area of the cube is 216 ft²

The total surface area is 756 ft²

The surface area of the pyramid = A + 1/2 ps

where

Therefore,

A = 6² = 36 ft²

p = 4(6) = 24 ft

s = √3² + 4² = √9 + 16 = √25 = 5 ft

Hence,

The surface area of the pyramid = 36 + 1 / 2 × 24 × 5 = 96 ft²

The surface area of the square base prism = 2a² + 4ah

where

Therefore,

The surface area of the square base prism = 2(6)² + 4(6)(20) = 72 + 480 = 552 ft²

The surface area of the cube  = 6l² = 6 × 6² = 6 × 36 = 216 ft²

Total surface area = 96 + 552 + 216 = 864 - 36  - 36 - 36 = 756 ft²

Step-by-step explanation:

We know that every triangle no matter will equal 180 degrees. So we will make an algebreic expression.

2x+8+60=180

When doing algebreic expression we want to simply as much as possible to find our answer. First we will do 60-180. Since the expression is adding 60 we want to do the opposite and subtract is by 60 on both sides. SO now we have 2x+8=120. We do the same thing with 8. Subtract it on  both sides since its adding in the expression. Now we have 2x=112. FInally, we will divide by two on both sides since its multiplying on the other side of the equation. So now we are left with x=56.

Step-by-step explanation:

we are looking in the table for values of x that give both f(x) and g(x) the same value.

x = 1 → f(x) = g(x) = 0

x = 3 → f(x) = g(x) = 6

(1, 0 ) and (3, 6 )

Answer:

Step-by-step explanation:

According to the table :

f(1) = 0 = g(1) ⇒ 1 is a solution to the equation f(x) = g(x)

f(3) = 6 = g(3) ⇒ 3 is a solution to the equation f(x) = g(x)

We expect to get the color green 10 times out of the 80.

The spinner is divided into 8 equal colors, so we can assume that each one of the 8 colors has the same probability of being spun.

This means that if we spin the spinner, the probability of getting the color green is p = 1/8.

So, in 80 tries, we will expect to get the color green a total of:

N = (1/8)*80 = 10

A shape can only be classified as a polygon if:

We can see that the figure is opened. Therefore, the shape is not a polygon. According to (2), to classify a shape, a polygon, the shape must not be opened.

Therefore, this shape is not a polygon.

This shape is a polygon because it has no curves, it is not opened, and the sides of the shape are not forming an intersection.

Therefore, this shape is a polygon.

This figure has a side length intersecting another side length. Therefore, this figure is not a polygon. According to (3), to classify a shape, a polygon, the sides of the shape must not intersect each other.

Therefore, this shape is not a polygon.

This figure is not a polygon because a side length of the figure is curved. According to (1), To classify a shape, a polygon, there must be no curves in the shape.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, we have that:

Item a:

The expected value of the binomial distribution is given by:

E(X) = np

Hence:

E(X) = 12 x 0.4 = 4.8 jurors.

Item b:

The proportion of 3 out of 12 is 3/12 = 1/4 = 0.25.

Item c:

The probability is given by:

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]

Then:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{12,0}.(0.4)^{0}.(0.6)^{12} = 0.0022[/tex]
