Answer:

B. Fixed fee for Company B is greater than Company A

Step-by-step explanation:

Company A:

A(n) = $0.99 + $0.25n

The function above is given in slope-intercept form, A(n) = mx + b (rewritten as A(n) = b + mx)

The unit rate (m) = per minute fee = $0.25

Fixed fee (b) = $0.99)

Company B: let's find the fixed fee (b), which is the y-intercept.

The y-intercept is the point on the y-axis where the line intercepts the y-axis.

If we draw a straight line, we would observe that the y-intercept (b) would be between 1.20 and 1.40.

Therefore, fixed fee for Company B would be between $1.2 and $1.4. this is greater than the fixed fee for Company A, which is $0.99.

Therefore, the statement that must be true is:

B. Fixed fee for Company B is greater than Company A

The midpoint of line segment UV is given by M ( -11/2 , 1 )

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

Measure the distance between the two end points, and divide by 2.

Let A ( x₁ , y₁ ) be the first point

Let B ( x₂ , y₂ ) be the second point

The midpoint between A and B is M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

Given data ,

Let the first point be U ( -8 , 9 )

Let the second point be V ( -3 , -7 )

Now , midpoint between U and V is M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

On simplifying , we get

a = ( -8 + -3 ) / 2

b = ( 9 - 7 ) / 2

On further simplification , we get

a = -11/2

b = 1

Hence , the midpoint is M ( -11/2 , 1 )

Answer:

  5/8

Step-by-step explanation:

The area of the smaller circles is proportional to the square of the ratio of their diameters. The two smallest circles have diameters equal to 1/4 the diameter of the largest circle. Hence their areas are (1/4)^2 = 1/16 of that of the largest circle.

Similarly, the medium circle has a diameter half that of the largest circle, so its area is (1/2)^2 = 1/4 of the are of the largest circle.

The smaller circles subtract 2×1/16 +1/4 = 3/8 of the area of the largest circle. Then the shading is 1-3/8 = 5/8 of the area of the largest circle.

Answer:

28

Step-by-step explanation:

the ratio is written as copies/dollars.

14/4=x/8

since we can multiply 4 by 2 to get 8, multiply 14 by 2 as well.

14/4=28/8

This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.

Elimination of the parameter means to rewrite the equations in terms of only x and y. To do this, substitute t from one equation into the other equation. Here, the two equations are:x = t1/3 and y = t – 4Substitute t from the first equation into the second equation:y = (x^3) – 4Now the equation is in terms of x and y only.

This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.The rectangular equation, y = (x^3) – 4 can be plotted on a graph. It is a cubic equation. The graph will look like a curve that passes through the point (0, -4) and continues to move towards infinity. The graph will be symmetric to the origin because the equation involves an odd power of x.

If the equation involved an even power of x, the graph would be symmetric to the y-axis. The graph will never touch the x-axis or y-axis, it will only approach them.In conclusion, the rectangular equation y = (x^3) – 4 is derived from the two parameter equations, x = t1/3 and y = t – 4. The graph of this equation is a cubic curve that is symmetric to the origin. The curve passes through (0, -4) and approaches the x and y-axes but never touches them.

The required area of the coat button with given radius of 6 millimeters is equal to 113.04 square millimeters.

Radius of the coat button is equals to 6 millimeters

let us consider 'A' be the area of the circle.

And 'r' be the radius of the circle.

Use the formula for the area of a circle we have,

A = πr^2

π (pi) is a mathematical constant approximately equal to 3.14.

Plugging in the given value of the radius we have,

⇒ A = π(6mm)^2

⇒ A = 36π mm^2

⇒ A = 36 × 3.14mm^2

⇒ A = 113.04 mm^2

Therefore, the area of the coat button is 113.04 square millimeters.

Step-by-step explanation:

8 halls would be required to accommodate 520 people in the hall.

As we know that a hall can accommodate 65 people.

To determine the number of hall required for 520 people,

first we need to find that how many halls would be required for one person,

So, we will divide the 1 by 6 to find :

The number of one person accommodate = 1/65 Hall

Then, 520 people required to accommodate = 1/65 × 520

                                                                      = 8 Halls.

Answer:

Total number of ways in which first, second and third prizes will be awarded = 560

Step-by-step explanation:

As given,

There are 16 players participated in a tennis tournament.

and 3 players will be awarded for first, second, and third prize.

As we know,

ⁿCₓ = \(\frac{n!}{x! (n-x)!}\)

n = the number of items.

x = how many items are taken at a time.

As given, n = 16 , x = 3

⇒¹⁶C₃ = \(\frac{16!}{3! (16-3)!} = \frac{16!}{3! (13)!} = \frac{16.15.14.13!}{3! (13)!} = \frac{16.15.14}{3!} = \frac{16.15.14}{3.2.1} = \frac{3360}{6} = 560\)

∴ we get

Total number of ways in which first, second and third prizes will be awarded = 560

Answer:

\(y=-\frac{4}{5}x-\frac{21}{5}\)

Step-by-step explanation:

The fastest way is to use point-slope form with \(m=-\frac{4}{5}\) and \((x_1,y_1)=(-4,-1)\):

\(y-y_1=m(x-x_1)\\y-(-1)=-\frac{4}{5}(x-(-4))\\y+1=-\frac{4}{5}(x+4)\\y+1=-\frac{4}{5}x-\frac{16}{5}\\y=-\frac{4}{5}x-\frac{21}{5}\)

To graph the line passing through (-4,-1) with slope m = -4/5, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where m is the slope and b is the y-intercept.

Substituting m = -4/5, x = -4, and y = -1, we can solve for b:

-1 = (-4/5)(-4) + b

-1 = 3.2 + b

b = -4.2

Therefore, the equation of the line is:

y = (-4/5)x - 4.2

To graph the line, we can plot the given point (-4,-1) and then use the slope to find additional points. Since the slope is negative, the line will slope downwards from left to right. We can find the y-intercept by setting x = 0 in the equation:

y = (-4/5)x - 4.2

y = (-4/5)(0) - 4.2

y = -4.2

So the y-intercept is (0,-4.2).

Using this point and the given point (-4,-1), we can draw a straight line passing through both points.

Answer:

A) 0.30

B) 0.9

C) 0.4

Step-by-step explanation:

Number of balls = 10

A ) probability that a ball drawn at random is numbered 3,4 or 5

 number on ball to be drawn = 3   i.e 3,4 or 5

 total number of balls = 10

hence the probability = 3 / 10 = 0.30

B ) probability that number written on two different balls drawn at random differs by 2 or more

p( numbers differ by 1 ) = 9 * (1/10) * (1/9) =  0.1

p( numbers on two balls differ by 2 or more ) = 1 - p( numbers differ by 1 )

                                                                           = 1 - 0.1 =  0.9

C ) Probabilty that the sum of the numbers on 3 balls chosen is even

even numbers = 5 which are ( 2,4,6,8,10 )

The even numbers that can be gotten by summation of three balls are

(4.6,8,10 ) = 4

hence the probability of picking three balls with replacement  whose sum = even number will be

= 4 / 10 = 0.4
