Thepotemich [5.8K]

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)

Dafna11 [192]

Answer:

$400 and $1,000

Step-by-step explanation:

Let us assume the x be the amount invested in 7% account

And, 600 + x be the amount invested in 9% account

Now the equation is

7x% + 9%(600 + x) = $118

0.07x + 54 + 0.09x = $118

0.16x = $118 -$54

0.16x = $64

x = $400

And, the other one is = $400 + $600 = $1,000

1. √48  →  √16 * √3  =  4√3

3.
 √12  →  √4 * √3  =  2√3

7. √125  →  √25 * √5  =  5√5

8. √20  →  √4  *  √5  =  2√5

9.  √18  →  √9  *  √2  =  3√2

10. √32  →  √16  *  √2  =  4√2

11.  √50  →  √25  *  √2  =  5√2

12.  √27  →  √9  *  √3  =  3√3
