Answer:

Make sure to get plenty of sleep, dont cram the night before the test. This will affect your thinking ability while taking the test.

Have several review sessions the week preceding the test, to make sure you've properly covered the material.

Have a good breakfast, I like toast with jam and oatmeal, sugary cereal can make your attention span low and affect how much effort you put into the test.

Take notes! Writing something down has often helped me memorize it better, and led to better performance on the test.\

Hope this helps!

Graph the image of this figure after a dilation with a scale factor of 2 centered at the origin.
den301095 [7]

Answer:  

Here, the coordinates of the given rectangle are (1,2), (3,2), (1,-1) and (3,-1)

In the dilation by the scale factor k with centered at origin,

(x,y)\rightarrow (kx,ky)

Thus, If the dilation occurs by the scale factor of 2 with centered at origin,

New coordinates of the Rectangle are,

(1,2)\rightarrow (2\times 1, 2\times 2)

(3,2)\rightarrow (2\times 3, 2\times 2)

(1,-1)\rightarrow (2\times 1, 2\times -1)

(3,-1)\rightarrow (2\times 3, 2\times -1)

Thus, the coordinates of new rectangle are,

(2,4), (6,4), (2,-2) and (6,-2)

Thomas wants to invite Madeline to a party. He has an 80% chance of bumping into her at school. Otherwise, he'll call her on the
mash [69]

Answer:

The probability of Thomas inviting Madeline to the party over the phone is 0.143.

Step-by-step explanation:

Consider the tree diagram below.

The events are denoted as follows:

<em>A</em> = Thomas bumps into Madeline at school

<em>B</em> = Thomas call Madeline on the phone

<em>X</em> = Thomas asks Madeline to the party

The information provided is:

P (A) = 0.80

P (B) = 1 - P (A) = 1 - 0.80 = 0.20

P (X|A) = 0.90

⇒ P (X'|A) = 1 - P (X|A) = 1 - 0.90 = 0.10

P (X|B) = 0.60

⇒ P (X'|B) = 1 - P (X|B) = 1 - 0.60 = 0.40

The conditional probability of event <em>U</em> given that another events <em>V</em> has already occurred is:

P(U|V)=\frac{P(V|U)P(U)}{P(V)}

The law of total probability states that:

P(V)=P(V|U)P(U)+P(V|U')P(U')

In this case we need to determine the probability that Thomas invites Madeline to the party over the phone, i.e. P (B|X).

Use the law of total probability to determine the value of P (X) as follows:

P(X) = P(X|A)P(A)+P(X|B)P(B)

         =(0.90\times 0.80)+(0.60\times 0.20)\\=0.72+0.12\\=0.84

Compute the value of P (B|X) as follows:

P(B|X)=\frac{P(X|B)P(B)}{P(X)}

             =\farc{0.60\times 0.20}{0.84}\\\\=0.14286\\\\\approx 0.143

Thus, the probability of Thomas inviting Madeline to the party over the phone is 0.143.
