The answer is option (c) 7xy^2-2xy^2
The expression is -11-(-2)
Two negatives equals to a positive so,
-11+2
=-(11-2)
=-9
The distance between -11 & -2 is -9
Hope that helped :)
Answer:
0.013
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
and p is the probability of success.
Given n = 6, p = 0.69, and r = 0 or 1:
P = ₆C₀ (0.69)⁰ (1−0.69)⁶⁻⁰ + ₆C₁ (0.69)¹ (1−0.69)⁶⁻¹
P = (1) (1) (0.31)⁶ + (6) (0.69) (0.31)⁵
P = 0.013
Answer:
0
Step-by-step explanation:
Given

Required
Determine its new position
Because the ring was initially below the surface of the pool;
Its initial position is

Taking it to the surface of the pool;
It means, the ring travels a distance of:

It's final position is the summation of its initial position and distance travelled;



<em>Hence, 0 represents its new position with respect to the surface of the water</em>
A = (B+b)·h/2 = 48 and B=b+6
2·48 = (b+6+b)·8
12 = 2b + 6
6 = 2b
b = 3 <span>inches
B = 9 </span><span>inches</span>
