Answer:

Mean score for the students = 593.3

Step-by-step explanation:

<u>Name</u>    <u>Score</u>

Julia      650

Andrew 550

Jason    380

Cathy     720

Jessica   710

Robert    550

1) Mean Score = \frac{Sum of the scores}{Total number of students}

= \frac{650+550+380+720+710+550}{6}

= 593.33

2) Upon rounding off to the nearest tenth, we get

Mean Score = 593.3 (since the hundredth digit is lesser than 5, the tenth digit is not increased)

Answer:

593.3


Step-by-step explanation:

Assuming random sample, assuming "point estimate of mean score" means "estimate of mean score in points",


(650+550+380+720+710+550)/6 is 593.3

Sample size 6 population size 25 is irrelevant except to note estimate might not be very good.

The coordinates of the vertices of triangle ABC are A(3,6), B(6, 3), and C(9, 9). If triangle ABC Is dilated by 1/3x and 1/3y to
katovenus [111]

Answer:

A' =  (1,2)

B'=(2,1)

C' =(3,3)

Step-by-step explanation:

Given

A = (3,6)

B = (6,3)

C = (9,9)

Scale = \frac{1}{3}

Required

Determine the vertices of ABC

If truly the question asks for the vertices of ABC, then the vertices are:

A = (3,6)   B = (6,3)   C = (9,9)

However, I'm quite sure that's not the requirement of the question. So, I'll solve for A'B'C'

To do this, we simply multiply the vertices of ABC by the scale of dilation.

(A'B'C') = Scale\ Factor * (ABC)

A' = \frac{1}{3} * A

A' = \frac{1}{3} * (3,6)

A' =  (\frac{3}{3},\frac{6}{3})

A' =  (1,2)

B' = \frac{1}{3} * B

B' = \frac{1}{3} * (6,3)

B' = (\frac{6}{3},\frac{3}{3})

B'=(2,1)

C' = \frac{1}{3} * C

C' = \frac{1}{3} * (9,9)

C' = (\frac{9}{3},\frac{9}{3})

C' =(3,3)
