The percent of Americans that had central heterochromia is A. 0061%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

In this case, it's estimated that only around 200,000 Americans have central heterochromia and the population of the United States

was 327,750,000 people.

The percent of Americans that had central heterochromia will be:

= Those with the disease / Total population × 100

= 200,000 / 327,750,000 × 100

= 0.0061%

The different ways to make groups of 4 based on the napkins given is 6 ways.

Combinations are also referred to as selections. Combinations implies the selection of things from a given set of things. In this case, we intend to select the objects. Thus can be illustrated by nCr

Combination formula

nCr = n! / ((n – r)! r!)

n = the number of items.

r = how many items are taken at a time

In this case, Elijah has red and yellow napkins. He must set out napkins for 4 people. This will be:

= n! / ((n – r)! r!)

= 4! / (4 - 2)! 2!

= 4! / 2!2!

The total amount accumulated after 2 years is $3704. 0

The formula for calculating compound interest is expressed as;

A = P ( 1 + r/ n) ^nt

Where;

Now, let's substitute the values into the formula, we have;

A = $3500 ( 1 + 0. 03 / 0. 25) ^(0.25× 2)

Find the exponent

A = $3500 ( 1 + 0. 03 / 0. 25) ^0.5

A =  $3500( 1+ 0. 12)^0. 5

Expand the bracket

A = $3500 (1. 12)^0. 5

A = $3500(1. 05)

multiply the values

A = $3704. 0

The values of y and x are -7 and 2 respectively, completing the ordered pairs: (6,-7) and (2,1).

Given the equation in the question;

To find the y-value that completes the ordered pair ( 6,y ), replace all occurrence of x with 6 in the equation and solve for y.

y = −2x + 5

y = −2( 6 ) + 5

Multiply -2 and 6

y = -12 + 5

y = -7

Hence, the output value is -7, this forms an ordered pair of (6,-7).

To find the x-value that completes the ordered pair ( x,1 ), replace all occurrence of y with 1 in the equation and solve for x.

y = −2x + 5

1 = −2x + 5

Add 2x to both sides

1 + 2x = −2x + 2x + 5

1 + 2x = 5

2x = 5 - 1

2x = 4

x = 4/2

x = 2

Hence, the input value is 2, this forms an ordered pair of (2,1).

a) 25 % of customers receive the service for​ half-price.

b) The guaranteed time​ limit should be of 16 minutes.

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score.

When the distribution is normal, we use the z-score formula.

The p-value is the probability that the value of the measure is smaller than X, which is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

we have that mean of 15 minutes and a standard deviation of 4 minutes.

​(a) Longer than 20 minutes is 1 subtracted by the p value of Z when X = 20. So

[tex]Z = \dfrac{{x} - \mu}{\sigma}[/tex]

Z = (20 - 15)/4

Z = 5/4

Z = 1.25

1.25 has a pvalue of 0.25

1 - 1.25= 0.25

25 % of customers receive the service for​ half-price.

(b)  The time limit should be the 100 - 7 = 93th percentile, which is X when Z has a pvalue of 0.93.  So X when Z = 0.25.

[tex]Z = \dfrac{{x} - \mu}{\sigma}[/tex]

The simplified expression of the expression given as -3x+16+5x+8 is 2(x + 12)

From the question, the equation is given as

-3x+16+5x+8

To start with, we need to rewrite the expression

So, we have the following representation

-3x + 16 + 5x + 8

The above expression is not an equation

Instead, it is an expression

This is so because there is no equality symbol i.e. = in the expression

So, we collect the like terms

-3x  + 5x + 8 + 16

Solving further, we need to evaluate the like terms

So, we have the following equation

-3x  + 5x + 24

Evaluate the like terms again

So, the equation becomes

2x + 24

The above expression cannot be further simplified, however, it can still be factored

Factor out 2 from the expression

This gives

The coordinates of G(4, 4) , H (0, 2),  J(8, 0)

In order to construct the three sets of relationships between the coordinates of each triangle's three sides' ends and the shared midpoint, we must first set up the three sets of relationships.

G(x(G), y(G))

K(2, 3) (2, 3)

M(6, 2) (6, 2)

H(x(H) and y(H))L (4, 1)

J(x(J), y(J))

K(2, 3) at the midway of side GH

According to the x-component:

x(H) = x(G - x(H))/2

x(G)-[x(H)-x(G)] = 2*x(H)

x(H) + x(G) = 4

x(H) = 4 - x(G) (G)

According to the y-component:

y(H) plus [y(G) - y(H)]/2 = 3.

2*y(H) plus [y(G-y(H)] = 6

y(H) + y(G) = 6

y(H) = 6 - y(G) (G)

Midpoint L(4) and side JH(1):

According to the x-component:

(x(H) + [x(J) - x(H)]/2) equals four.

2*x(H) plus [x(J)-x(H)] = 8

x(H) + x(J) = 8

x(H) = 8 - x(J) (J)

According to the y-component:

y(H) = y(J - y(H)]/2 + y(J) = 1

y(J) - y(H) = 2*y(H)

y(H) + y(J) = 2

y(H) = 2

Side GJ with M(6, 2) as the midpoint:

For the x - component, the formula is: x(J) = [x(G) - x(J)]/2 = 6 2*x(J) = [x(G)- x(J)] = 12 x(J) = 12 - x (G)

y(J) + [y(G) - y(J)]/2 = 2 2*y(J) + [y(G)- y(J)] for the y-component. = 4 y(J) = 4 - y + y(G) = 4 y(J) (G)

The x and y coordinates may now be easily separated, and we can use algebra to isolate each one and determine its location.

x(H) = 4 - x(G), 8 - x(J), and 12 - x(J) (G)

Because x(H) = x (H)

4 - x(G) = 8 - x(J) (J)

8 - x(J) - 8 - x(G) - 4 = -x(J) x(J) x(J) = 4 + x (G)

Using 1.c above and this relationship now x(J) = x(J), so:

-2 * x(G) = -8 x(G) =, 4 12 - x(G) = 4 + x(G) 12 - x(G) - x(G) - 12 = 4 + x(G) - x(G) - 12

Given that x(J) = 4 + x(G) above, x(J) = 4 + 4 = 8 and x(H) = 4 - x(G) = 4 - 4 = 0 respectively.

Let's now perform the identical procedure using the y-coordinates.

y(H) = 6 - y(G), y(H) = 2 - y(J), y(J) = 4 - y(G),

and since y(H) = y(H), 6 - y(G) = 2 - y(J), -y(G) = 2 - y(J) - 6 = -y(J) - 4 y(G) = y(J) + 4 Now that y(J) = 4 - y,

we may substitute (G).

y(H) = y(G) - 2 and y(H) + 4 - y(G) = 2

and y(H) + 4 - y(G) = 2 - 4 and y(G)

Since y(H) = 6 - y(G)

according to 1. above, y(H) = y(G) - 2 + 6 - y(G) 2 * y(H) = 4 y(H) = 2 y(H) = 2 - y(J) 2 = 2 - y(J) y(J) = 4 - y(G) 0 = 4 - y(G) y(G)

H(x(H), y(H)), G(x(G), y(G)), and J(x(J), y(J)) are the results.

To determine the coordinates of the angles or triangle's tips, we used the midpoints of each side.

The coordinates are: H (0, 2) G(4, 4) J(8, 0)
