<span> value
Weighted mean average = ---------------------------
number of brands
value = mean price of computers from Store
#1 * number of brands from store #1 + mean price of computers from store #2 * number of brands from store #2
value = $799.99 * 2 + $679.99 * 4 = $4,319.94
number of brands = 2 + 4 = 6
weighted average = $4,319.94 / 6 = $ 719.99
Answer: option b. $719.99

Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
Answer:I think it is true
Step-by-step explanation: If you oversteer then it should loose the traction. But I am not sure hope this helps
Answer:
The standard parabola
y² = -18 x +27
Length of Latus rectum = 4 a = 18
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given focus : (-3 ,0) ,directrix : x=6
Let P(x₁ , y₁) be the point on parabola
PM perpendicular to the the directrix L
SP² = PM²
(x₁ +3)²+(y₁-0)² = 
x₁²+6 x₁ +9 + y₁² = x₁²-12 x₁ +36
y₁² = -18 x₁ +36 -9
y₁² = -18 x₁ +27
The standard parabola
y² = -18 x +27
Length of Latus rectum = 4 a = 4 (18/4) = 18
