The scale factor of the enlargement will be 3. Then the center of enlargement is marked in the diagram.

<h3>What is dilation?</h3>

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

Shape A is enlarged to give shape B.

Then the scale factor of the enlargement will be

⇒ 3 / 1

Then the center of enlargement is marked in the diagram.

More about the dilation link is given below.

Answer:

c = \frac{1}{10}

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

C = f+cm

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

3000=f+c15000, 3500=f+c20000

Si restamos la segunda ecuación de la primera, tenemos que

3500-3000 = f-f+(20000c-15000c)

Luego

500 = 5000c

Entonces c = \frac{500}{5000} = \frac{1}{10}

Si tomamos la primera ecuación, tenemos que 3000-\frac{15000}{10} = f. Es decir,

3000-1500 = f = 1500

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.

You randomly choose an undergraduate student from a large state university. Let E be the event that the student is male, let F b
erik [133]

Answer:

( a ) is the right answer .

Step-by-step explanation:

P(E) = 0.48

Probability of being male = .48

Probability of being female = .52

P(F) = 0.72

Probability of being in state  = .72

Probability of being out of state  = .28

P(G) = 0.55

Probability of being in at least 20 years   = .55

Probability of being less than 20  = .45

a )

P(student is an in-state male younger than 20)

= .72 x .48 x .45 = .1555 = .156

b )

P(student is an out-of-state female younger than 20)

= .28 x .52 x .45

= .065

c )

P(student is an in-state female younger than 20)

= .72 x .52 x .45 = .168

d )

P(student is an out-of-state male at least 20)

= .28 x .48 x .55 = .074

So , ( a ) is the right answer .
