GenaCL600 [577]

Answer:32,768

2*4=8*4=32*4=128

So we have to multiply by 4

128*4=512 5th term

512*4=2048 6th term

2048*4=8192 7th term

8192*4=32768 last term

Search cos jk and tan jk knowing that sin jk = 8/3
aleksley [76]

Answer:

cosjk = √55 i/3

tanjk = 8/√55 i

Step-by-step explanation:

Given

sin jk = 8/3

According to SOH CAH TOA

Sin theta = opposite/hypotenuse = 8/3

Opposite = 8

hypotenuse = 3

Get the adjacent using the pythagoras theorem

hyp² = opp²+adj²

adj² = hyp² - opp²

adj² = 3² - 8²

adj² = 9-64

adj² = -55

adj = √-55

adj = √55 i (i = √-1)

Get cosjk

cosjk = adj/hyp

cosjk = √55 i/3

Get tanjk

tanjk = opp/adj

tanjk = 8/√55 i

On average, Nancy has noticed that 20 trucks pass by her apartment daily (24 hours). In order to find the probability that more
sukhopar [10]

Answer: Our required probability is 0.384.

Step-by-step explanation:

Since we have given that

In  24 hours,

λ = 20

In 6 hours,

\lambda=\dfrac{20}{24}\times 6=\dfrac{20}{4}=5

As we know that it is a Poisson distribution.

E[X] = λ  = 5

Probability that more than 6 trucks will pass her apartment is given by

P(X>6)=\sum_{x=6}^{20}\dfrac{e^{-5}\times 5^x}{x!}=0.384

Hence, our required probability is 0.384.
