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 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.

Answer:

It has a minimum of -3 and a unkown maximum

Step-by-step explanation:

The value of x that would make line segment T V is parallel to line segment Q S is where x = 10. (Option C)

In Mathematics, a Line Segment is a part of a line that has two endpoints.

The difference between a line segment and a line is that while the former has a starting and an endpoint, the latter does not. See the attached image.

Step 1

Note that if QS is Parallel to TV, then both sides of the triangle must be proportionally divided by TV.

That is: RV/VS = RT/TQ.

Step 2 - replace the segments by the relevant equations

(X + 4)/(X- 3) = (X+10)/(X)

Step 3 - Cross Multiply

 x(x +4) = (x -3)(x +10)

Removing the parentheses, we have

 X² +4X = X² +7X -30; Subtract X² from both sides and we have;

4X = 7X - 30

-3X = -30 or

3X = 30

Divide both sides by three and we have:

X = 10

The instantaneous rate of change in the percent of households that used the internet for electronic banking in the year 2000 is; 6.8%

Formula for instantaneous rate of change is;

f'(x) = (f(b) - f(a))/(b - a)

From the table showing the the percent of households that used the internet for electronic banking in the year 2000, we can find the instantaneous rate of change as;

f'(2000) = (f(2001) - f(1999)]/(2001 - 1999)

f'(2000) = (21.6 - 8)/(2001 - 1999)

f'(2000) = 13.6/2

f'(2000) = 6.8

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.

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

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:

8

Step-by-step explanation:

Re-write the equation:

h(x) = x² * 2 - x² -7x

If X is equal to -8, then we can re-write the equation as:
h(-8) = (-8)² * 2 - (-8)² - 7(-8)

Following P.E.M.D.A.S. we must first solve for the exponents:

h(-8) = (64) * 2 - (64) - 7(-8)

Then we need to solve the multiplication.

h(-8) = (128) - (64) - (-56)

Now, we solve for the addition/subraction.

h(-8) = (128) - (120)

Lastly...

128 - 120 = 8

This means that if h(-8), then H = 8
