The percentage of men who didn't expect to meet the height requirements be 96.29%
Given, that the heights of men are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches.
Find the percentage of men who meet the height requirements.
z(64) = (64-69)/2.8 = 1.7857
z(78) = (78-69)/2.8 = 3.2143
P(64 <= x <= 78) = P(1.78457<= z <=3.2143) = 0.0371 = 3.71%
So, the percentage of men who meet the height requirements be 3.71%
Now, the percentage men who didn't expect to meet the height requirements be
100 - 3.71 = 96.29%
Hence, the percentage of men who didn't expect to meet the height requirements be

Construct the graph of the equation given by solving for the intercepts. Show all of the steps in finding the intercepts and then
plot the intercepts to create the graph. Label the intercepts, as well as the axis on the graph.
2x+3y=6
The slope and the intercepts of the graph are determined.
Given:
the equation is :
2x+3y=6
we first find the slope of the equation:
m = -a/b
m = -2/3
now solve the intercepts:
to find x intercept, substitute in 0 for y and solve for x.
⇒ 2x+3y=6
⇒ 2x+3(0)=6
⇒ 2x+0=6
⇒ 2x=6
⇒ x=6/2
⇒ x=3
hence we get (3,0)
now, to find y intercept, substitute in 0 for x and solve for y.
⇒ 2x+3y=6
⇒ 2(0)+3y=6
⇒ 0+3y=6
⇒ 3y=6
⇒ y=6/3
⇒ y=2
hence we get (0,2) as the intercepts.
Therefore we plot the required graph.

an airplane ticket has a perimeter of 58 cm and an area of 198 square cm. What are the dimensions of the ticket
The dimensions of the ticket are width is 11 cm and length is 18 cm.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
An airplane ticket has a perimeter of 58 cm and an area of 198 square cm.
Let W is the width of the ticket and L is the length of the ticket
The area of a credentials= L × W
198 = L × W ...(i)
The perimeter of a ticket = 2(L+W)
58 = 2(L+W)
29 = L + W
L = 29 - W ...(ii)
Substitute the value of L = 99 - W in equation (i)
198 = (29 - W) × W
198 = 29W - W²
0 = W² - 29W + 198
[tex]0=\left(W^2-11W\right)+\left(-18W+198\right)[/tex]
[tex]0=W\left(W-11\right)-18\left(W-11\right)[/tex]
[tex]0=\left(W-11\right)\left(W-18\right)[/tex]
W = 18 or 11

The volume of the given figure is 5760 [tex]cm^{3}[/tex].
According to the question,
We have the following information:
We have a figure where two cuboids are joined together. So, the volume of the figure will be the sum of the volume of these cuboids.
We know that the following formula is used to find the value of cuboid:
Volume of cuboid = Length*breadth*height
Volume of larger cuboid = 40*8*12
Volume of larger cuboid = 3840 [tex]cm^{3}[/tex]
Volume of smaller cuboid = 20*8*12

Given that ABCD is a rectangle, where EC = 7x -3 and AE=4x + 8. Find DE.
The length of segment DE on the rectangle, considering the midpoint, is given as follows:
DE = 22.67.
What is the midpoint?The midpoint of a segment divides a segment into two segments of equal length, having half the length of the entire segment.
In this problem, the diagonal of the rectangle represented by segment AC has midpoint E, hence the measure of x is calculated as follows:
EC = AE.
The measures are as follows:
EC = 7x - 3.AE = 4x + 8.Hence:
7x - 3 = 4x + 8
7x - 4x = 8 + 3
3x = 11
x = 11/3.
Segment DE is also half of a diagonal, hence it's length is obtained with the numeric value of any segment EC or AE, as follows:
DE = EC = 7x - 3 = 7 x 11/3 - 3 = 77/3 - 9/3 = 68/3 = 22.67.

What is a Quadratic equation ?
A second-degree equation of the form ax² + bx + c = 0 is known as a quadratic equation in mathematics. Here, x is the variable, c is the constant term, and a and b are the coefficients. Since x is a second-degree variable, this quadratic equation has two roots, or solutions.
Given expression is,
8x² = 6 + 22x
Rewrite this expression as,
8x² - 6 - 22x = 0
8x² - 22x - 6 = 0
Now, we get the form quadratic equation i.e, ax² + bx + c = 0
Solve the equation and find roots
8x² - 22x - 6 = 0
2(4x² - 11x - 3) = 0
4x² - 11x - 3 = 0
4x² - 12x + x - 3 = 0
Take common terms out,
4x(x - 3) + 1(x - 3) = 0
we get the brackets same that means we're on right way,
(4x + 1) (x - 3) = 0
split the values into two,
4x + 1 = 0 and x - 3 = 0
4x = -1 x = 3

Find the value of k so that the system of equation has no solution
kx + 6y = 6
y = 2/3x - 4
The value of k so that the system of equation has no solution is k = -4
How to find the value of k so that the system of equation has no solution?Since we have the system of equations
kx + 6y = 6
y = 2/3x - 4
For the system of equations to have no solution, the determinant coefficient matrix must be zero.
Re-arranging the equations, we have
kx + 6y = 6
-2/3x + y = - 4
So, the coefficient matrix is
[tex]\left[\begin{array}{ccc}k&6\\-2/3&1\end{array}\right][/tex]
So, the determinant D = k × 1 - (-2/3) × 6
= k + 2/3 × 6
= k + 2 × 2
= k + 4
Since the determinant must be zero for the system of equations to have no solution, we have that
D = 0
k + 4 = 0
k = -4
So, the value of k = -4

There needs to be

The mixture of 13% disinfectant solution needs to be made with 8 gallons of 11% solution and 4 gallons of 17% solution respectively.
How to find the number of gallons of solution needed?Let
gallons of 11% solution = xgallons of 17% solution = yx + y = 12
0.11x + 0.17y = 0.13 × 12
x + y = 12
0.11x + 0.17y = 1.56
From (1)
x = 12 - y
Substitute into (2)
0.11x + 0.17y = 1.56
0.11(12 - y) + 0.17y = 1.56
1.32 - 0.11y + 0.17y = 1.56
- 0.11y + 0.17y = 1.56 - 1.32
0.06y = 0.24
divide both sides by 0.06
y = 0.24/0.06
y = 4
Substitute y = 4 into (1)x + y = 12
x + 4 = 12
x = 12 - 4
x = 8
So therefore, the gallons of 11% solution and
gallons of 17% solution needed are 8 and 4 gallons respectively.
