Find the component form of the vector that translates P(4,5) to p'.

Veronika [31]

Answer:

Component form : (-7 , 2)

Step-by-step explanation:

P(4 , 5) = P'(4 +x , 5+y) = P'(-3 , 7)

4 + x = -3

x = -3 - 4

x = -7

5 + y = 7

y = 7 - 5

y = 2

Vector form : -7i + 2j

mamaluj [8]

Answer:

<em>Bethany did not do better than Richie because her average score was less than his.</em>

Step-by-step explanation:

<u>Average Value</u>

The average or mean value of m successes out of n tries is given by:

$\displaystyle \bar x=\frac{m}{n}$

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

$\displaystyle \bar x=\frac{12}{15}=0.8$

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

$\displaystyle \bar x=\frac{8}{11}=0.72$

Bethany did not do better than Richie because her average score was less than his.
