The result concluded is equivalent to a single rotation transformation of the original object.

<h3>Explanation of how reflection across axis works?</h3>

When a graph is reflected along an axis, say x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.

The Compositions of Reflections Over Intersecting Lines states that if we perform a composition of two reflections over two lines that intersect.

The result concluded is equivalent to a single rotation transformation of the original object.

Answer:

a) The required sample size n= 55011,57025

b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary

Step-by-step explanation:

Range

$σ = \frac{4-0}{4} = 1$

$E = 0,011 \\c= 99 %\\$ ⇒ 0,99

Sample size can be determinate using equation:

$n=(\frac{Z_{\alpha /2 * σ} }{E})^{2}$

Using confidence level desired 99% $Z_{\alpha /2}$ = 2,58

Table used :

Confidence $Z_{\alpha/2 }$

90 % 1,60

95 % 1,96

 99 % 2,58

99,9 % 3,291

So replacing:

$n=(\frac{2,58 * 1 }{0,011})^{2}$

$n= 234,5454545^{2} \\n=55011,57025$

frez [133]

constraint 1
let
x = number of cups of chocolate
y = number of cups of vanilla
The equation that represents the total number of ice cream is:
x + y = 24
constraint 2
the ratio of the number of chocolate cups to vanilla cups is
y = (1/2) x
Using equations 1 and 2, you can find the number of cups of each favor required.
answer:
x + y = 24
y = (1/2) x

Hello There,

P represent the unknown information.

Write an equation to model the problem. 28 ÷ 2 – 4 .

P number, 10, 11, or 12, will solve the equation in Part (b)? Show your work. The reason 10 solves the equation is: 28 ÷ 2 – 4 = 10.

28 ÷ 2 – 4=14-4=10

Hope this helps Have a Wonderful Day! Bye!
