Answer:

answer b (0.73)

Step-by-step explanation:

"Triple" means to increase in size by a factor of 3.  

Thus, B = (1 + r)^2 becomes

3 = (1 + r)^2.  Our task is to determine the value of r, the annual interest rate.

Taking the square root of both sides, we get

√3 = 1 + r, which yields √3 - 1 = r.

This is approx. 1.732 - 1.000, or 0.732.  Answer b) is closest.

natulia [17]

Answer:

The mean is 0.54 and the standard deviation is 0.0135.

Step-by-step explanation:

i) the mean of the sampling distribution is 0.54

ii) the mean for the sampling distribution, p = 0.54

iii) therefore for the sampling distribution, q = ( 1 - 0.54) = 0.46

iv) the sample size of the distribution, n = 1356

v)  the\hspace{0.1cm} standard\hspace{0.1cm}  deviation\hspace{0.1cm}  s = \sqrt{\frac{p\times q}{n} }  = \sqrt{\frac{0.54\times 0.46}{1356} } = 0.0135

Find ????⋅ ???? if |????|=3 , |????|=9 , and the angle between ???? and ???? is π2 radians.
mrs_skeptik [129]

Answer:

a{\cdot}b=0

Step-by-step explanation:

It is given that,

Magnitude of a A, |A|=3

magnitude of B, |B|=9

The angle betwern a and b is \dfrac{\pi}{2}\ rad=90^{\circ}

Dot product,

a{\cdot} b=|a||b|\ \cos\theta\\\\a{\cdot} b=3\times 9\times \ \cos(90)\\\\a{\cdot} b=0

So, a.b is equal to 0.
