Answer: -7/9
Step-by-step explanation: 12-19=-7 and 10-19 = -9, so -7/9.
Given a scalar number

and a vector
v, the product between

and
v is a vector, with
- magnitude given by the product between the absolute value of

and the magnitude of
v- direction given by the sign of

: if a is positive, the final vector has same direction of
v; if a is negative, the final vector has opposite direction to
v.
In our problem, the scalar number is

. This means that the product between the vector and this number:
- has magnitude equal to

times the magnitude of the vector
- has opposite direction with respect to the original vector (because the scalar

is negative)
Therefore, the correct answer is
<span>B.) The vector will change direction and decrease in magnitude.</span>
Answer:
0.3573 = 35.7%
Step-by-step explanation:
We roll a pair of dice 10,000 times so the mean and standard deviation is,
μ = 10000/36 =277.7 σ = 
= (280 - 277.7)/16.4 = .14
= (300 - 277.7)/16.4 = 1.35
Probablity (range)
0.3573
Z(low)=0.14 0.555766357
Z(upper)=1.36 0.91304644

Answer: -3, write the division as a fraction, multiply both sides by 2, move constants to the right, then you're left with x=6-9 which is -3
