Study guide help?
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)

How do I find a2 and a3 for the following geometric sequence? 54, a2, a3, 128
vlada-n [284]
The formula for the nth term of a geometric sequence:
a_n=a_1 \times r^{n-1}
a₁ - the first term, r - the common ratio

54, a_2, a_3, 128 \\ \\
a_1=54 \\
a_4=128 \\ \\
a_n=a_1 \times r^{n-1} \\
a_4=a_1 \times r^3 \\
128=54 \times r^3 \\
\frac{128}{54}=r^3 \\ \frac{128 \div 2}{54 \div 2}=r^3 \\
\frac{64}{27}=r^3 \\
\sqrt[3]{\frac{64}{27}}=\sqrt[3]{r^3} \\
\frac{\sqrt[3]{64}}{\sqrt[3]{27}}=r \\
r=\frac{4}{3}

a_2=a_1 \times r= 54 \times \frac{4}{3}=18 \times 4=72 \\
a_3=a_2 \times r=72 \times \frac{4}{3}=24 \times 4=96 \\ \\
\boxed{a_2=72, a_3=96}
