Answer:
w = -7, -6
Step-by-step explanation:
Solve the equation by factoring:
(w+7)(w+6) = 0
Set each parenthesis equal to zero, and solve for w:
w = -7, -6

We have 4 apples, 3 peaches, and 4 pears.
The sample size is 11.
1st selection: apple
The probability of selecting an apple is 4/11.
2nd selection: peach
We now have a sample size of 10, which consists of 3 apples, 3 peaches, and 4 pears.
The probability of selecting a peach is 3/10.
3rd selection: peach
We now have a sample size of 9, which consists of 3 apples, 2 peaches, and 4 pears.
The probability of selecting a peach is 2/9.
Each selection was an independent event. Therefore the overall probability is
(4/11)*(3/10)*(2/9) = 4/165
Answer:
The probability of selecting an apple followed by 2 peaches is 4/165.
This probability is equivalent to 0.024 or 2.4%.
Step-by-step explanation:
well, I see one large rectangle (20×6), and 2 small triangles with their horizontal sides being (20-8-6)/2 = 3 m. and their vertical joined side being 10-6 = 4 m.
the total area is simply the sum of the rectangle and the 2 triangles.
the rectangle is
20×6 = 120 m²
each triangle is
4×3/2 = 2×3 = 6 m²
we have 2 of them, so their combined area is 2×6 = 12 m².
the total area is
120 + 12 = 132 m²
<span> RdΘ/dt = v </span>
<span>dΘ/dt = (1/3)/20 = 1/60 rad/sec </span>
<span>5(1/60 ) = 5/60 cm/sec = 1/12 cm/sec </span>
<span>Angular Speed = dΘ/dt = 1/60 rad/sec </span>
<span>Linear Speed = RdΘ/dt = 1/12 cm/sec </span>
Multiply 2 by 7, which is 14, and add it to the 4 in the numerator. The fraction becomes 18/7
