The probability that the event that the second part is defective will be 0.0564.

From the information, the bin of 50 manufactured parts contains 3 defective parts and 47 nondefective

Therefore, the probability of having a defective and non defective parts will be:

= 47/50 × 3/50

= 0.94 × 0.06

= 0.0564

The expression is written as 2 × 10 =  2 x 10^ 1  = 20

The index form of a number  can be defined as that number written as an exponential expression.

It is also said to be a single number that is  raised to another number.

Given the expression;

2x _____ = 2 x 10^ 1 = ______

Note that a number raised to the power 1 is that same number, so we have;

2 × 10

2 x 10^1 = 2 × 10

2 × 10  = 20

The total number of penalty kicks is 9+ 2y where the penalties made is x and the penalties missed is y

The given parameters are:

Leroy made 9 more penalty kicks than he missed

Represent the penalties made with x and the penalties missed with y

So, we have

x = 9 + y

The total number of penalty kicks is then calculated as

Total = x + y

This gives

Total = 9 + y + y

The volume of the solid generated by revolving the region bounded by the given curve and lines about the x-axis is V = 8π/3

The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

[tex]V = \pi \int\limits^a_b {f(x)^2} \, dx[/tex]

To find the area, integrate around that area. We're revolving around the x-axis so the area will be a circle;

V = ∫A(x)dx =  ∫(πr²)dr

Then we subtract them from each others.

∫(πr₂² - πr₁²)dr

Now substitute the value and integrate;

∫(π(2)² - π(2x)²)dr

∫(4π - 4πx²)dr

4π∫(1 - x²)dr

Now integrate from 0 to 1 since that's where our boundary is.

V = 4π∫(1 - x²)dr = 8π/3

Second part;

Third part;

The quadratic equation that represents the projectile motion can be presented as follows;

[tex]h(t) = - g \cdot {t}^{2} + v_{0}\cdot {t} + h_{0}[/tex]

g = 16 ft./s² or 9 m/ s²

First part;

When

[tex] v_{0} = 0 \: and \: h_{0} = 100 \: ft.[/tex]

We have;

h(t) = -16•t² + 100

When the object hits the ground, we have;

h(t) = 0, which gives;

0 = -16•t² + 100

Therefore;

16•t² = 100

t² = 100 ÷ 16 = 25/4

t = √(25/4) = 5/2 = 2.5

Second part;

The direction in which the object is thrown = Upwards

Initial height of the object, [tex] h_{0} = 6 \: ft[/tex]

Initial speed of the object, [tex] h_{0} = 30 \: ft/sec[/tex]

The equation of the projectile motion is therefore;

h(t) = -16•t² + 30•t + 6

Which gives;

When the object is at its starting height of 6 feet, h(t) = 6, which gives;

6 = -16•t² + 30•t + 6

-16•t² + 30•t = 0

A solution to the above equation is t = 0

The other solution is found as follows;

-16•t² + 30•t = 0

-16•t + 30 = 0

30 = 16•t

t = 30/16 = 1.875

Third part;

When the object hits the ground, we have;

h(t) = 0, which gives;

0 = -16•t² + 30•t + 6

Line m passes through the point value of k is -1/3.

Now let us find the slope of the equation using the slope equation of line:

y = mx + b,

From the given slope let’s find y,

y-7= -3/2(x+4)

y-7= -3/2x - 6

y= -3/2x + 1

=-1 / (-3/2)

=2/3

As these two lines are perpendicular the product of the slopes is -1.

m= 2/3 , y=-1

Line m is given as  y=2/3 x +b

As the line m passes through the points

(-1, 4) and (5, k)

X=4,

To find b

-1 = 2/3 * 4+b

-1=8/3+b

b=-11/3

By substituting all the values in the formula we get value of k,

Line m : y=2/3*-11/3

When x=5

k=y=2/3*5-11/3

=10/3-11/3

=-1/3

K = -1/3

A perpendicular is a straight line that makes an angle of 90° with any other line. 90° is also known as a right angle and is marked through a little square among two perpendicular lines.

Answer: k=8

Step-by-step explanation:

To find the value of k in the equation y-7=-3/2(x+4), we need to determine the slope of the line given by this equation.  

First, let's rewrite the equation in slope-intercept form (y = mx + b),

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

y - 7 = -3/2(x + 4) y - 7 = -3/2x - 6 y = -3/2x - 6 + 7 y = -3/2x + 1  

Comparing this equation with the general slope-intercept form, we can see that the slope (m) is -3/2.  

Since the line y - 7 = -3/2(x + 4) is perpendicular to line m, we know that the slopes of the two lines are negative reciprocals of each other.  

The negative reciprocal of -3/2 is 2/3.  

Therefore, the slope of line m is 2/3.

We know that line m passes through the points (-1, 4) and (5, k). Using the slope-intercept form, we can write the equation of line m as:

y = 2/3x + b  Substituting the coordinates (-1, 4) into the equation,

we can solve for the y-intercept (b):  4 = 2/3(-1) + b 4 = -2/3 + b 4 + 2/3 = b 12/3 + 2/3 = b 14/3 = b  Therefore, the equation of line m is:  y = 2/3x + 14/3  Substituting the x-coordinate 5 and solving for k:  k = 2/3(5) + 14/3 k = 10/3 + 14/3 k = 24/3 k = 8  Hence, the value of k is 8.

The force on one of the ends due to hydrostatic pressure is 332.8lb.

How is a hydrostatic pressure produced?

The force on one of the ends due to hydrostatic pressure is 332.8lb

Data;

Density = 62.4 lb/ft^3

length = 4ft

radius = 2ft

Force Due to Pressure

The force due to hydrostatic pressure can be calculated as

From the attached diagram

F = Pressure * area

density = 62.4 lb/ft³

depth of water = 2- y

pressure  = ( 2- y ) ( 62.4)

                = 124.8 - 62.4

We can proceed as

x² + ( y - 2)² = 2²

x² = 4 - ( y - 2)²

x = ± √4y - y²

this implies that

2x = 2 √4y - y²

The area is given as

δA = ( 2x) * δy

δA = 2√4y - y² δy

The force would be given by

δF = ( 2- y ) ( 62.4) (2 √ 4y - y²)δy

The total force is given by

F = [tex]\int\limits^2_0 {( 2 - y)} \, (62.4) ( 2\sqrt{4y - y^{2} } dy[/tex]

F = 124.8 [tex]\int\limits^2_0 {( 2-y)} \,( \sqrt{4y - y^{2} } dy[/tex]
