rosijanka [135]

Answer:

$9398.50

Step-by-step explanation:

Given

\$1 = 106.40\ ALL

Required

Equivalent of 1,000,000 ALL

We have:

\$1 = 106.40\ ALL

and

\$x = 1000000\ ALL

Cross Multiply

x * 106.40 = 1 * 1000000

106.40x = 1000000

Solve for x

x = 1000000/106.4

<em></em>x = \$9398.50<em> -- Approximated</em>

Answer:

Step-by-step explanation:

Garrett achieves a field goal is independent of each kick.  Hence X no of kicks is binomial with p = 0.83, and q =0.17

No of trials 3

Hence X can take values as 0 ,1,2,3 and

P(X=r) = 4Cr(0.83)^r (0.17)^{4-r}

, r=0,1,2,3

Using the above we obtain prob distribution as

X         0                  1           2            3                

P(X)   0.0049   0.0720   0.3513   0.5718

P(X>=2) =P(X=2,3,4) =0.9231

-----------------------------------------

2) Z value for company A =\frac{260-272}{5.4} =-2.22

Z value for company B = (260-249)/3.8 =2.89

From z value probablility is more for company A as

P(Z>-2.22) >P(Z>2.89)
