Work Shown:

A = pi*r^2

A = 3.14*(4.25)^2

A = 56.71625

A = 56.72

The P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%, and P(pass | Test C) is 22.07%

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Part A:

Total number of students = 154

Total number of students passed the test = 49

The probability:

P(pass | Test A) = 49/154 = 31.81%

Part B:

Total number of students = 154

Total number of students passed the test = 46

The probability:

P(pass | Test B) = 46/154 = 29.87%

Similarly, for the probability:

P(pass | Test C) = 34/154 = 22.07%

Thus, the P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%, and P(pass | Test C) is 22.07%

The equation of the circle represented by the pizza is x^2 + y^2 = 4

The given parameters are:

Radius, r = 2

Center, (a,b)= (0,0) i.e. origin

The equation of the circle is calculated as:

(x - a)^2 + (y - b)^2 = r^2

This gives

(x - 0)^2 + (y - 0)^2 = 2^2

Evaluate the exponents

x^2 + y^2 = 4

Hence, the equation of the circle is x^2 + y^2 = 4

The quadratic function f(x) = x² has the smallest x-intercept value in comparison with the linear function f(x) = 3 · x - 9, which is located at x = 0.

x-intercept is the point of a function that goes through the x-axis. Quadratic functions have at most two x-intercepts and linear functions have always one x-intercept.

In both expressions those intercepts are found by solving expression for x when y is equal to zero. In this question we must determine the smallest x-intercept value from one of the two polynomic functions:

a) f(x) = 3 · x - 9

3 · x - 9 = 0

x = 3

b) f(x) = x²

x² = 0

x = 0

The quadratic function f(x) = x² has the smallest x-intercept value in comparison with the linear function f(x) = 3 · x - 9, which is located at x = 0.

Step-by-step explanation:

[tex]A = \frac{\theta}{360^\circ}\times \pi r^2[/tex]

In this problem, we are given the area [tex]A[/tex], and the angle [tex]\theta[/tex]. We can set up an equation to solve for the radius, which is x:

[tex]A = \frac{\theta}{360^\circ}\times \pi r^2\\128 = \frac{152}{360}\times \pi r^2\\128 \times \frac{360}{152} = \pi r^2\\\frac{5760}{19} = \pi r^2\\r = \sqrt{\frac{5760}{19 \pi}}\\r \approx 9.823[/tex]

The polygon abcdef in the coordinate plane shown with area of 18 square units.

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

We have vertices for the polygon:

a=(-2,-3), b=(0,-3), c=(0,1), d=(3,1), e=(3,3), f=(-2,3)

After marking the coordinates on the coordinate plane and connecting the lines, we will get a polygon.

We can find the area of the shape:

Area of the shape = 18 square units

Thus, the polygon abcdef in the coordinate plane shown with area of 18 square units.

Answer:

87.5%

Step-by-step explanation:

add the number of students who took test A (49+7=56)

take the number of students who passed test A and divide it by the number of students who took the test A

49÷56=.875= 87.5%

The number of whole revolutions for 1000 meters is 265, while the time taken to move 1000 meters with a speed of 40rev/min is 7minutes.

This is the number of times a body moves round  a circular path.

A revolution is equal to the circumference of a circle.

Analysis:

r  = 120/2 = 60cm

1 revolution of a circle = 2πr

Let n be the number of revolutions

so that 2πr x n = 1000 x 100 since 100 cm = 1 m

n = 100000/2πr = 265 revolutions

If the Fan turns 40 rev / minute

Then it 265 revolutions = 1000 meters, 265/40 = 7 minutes

In conclusion, the number of revolutions for 1000 meters is 265 and the time taken for 265 revolutions is 7 minutes.
