D(n)=-5(1/2)^n-1 what is the 3rd term in the sequence

Studentka2010 [4]

Answer:

-1.25

Step-by-step explanation:

Better to write this as

a(n)= -5(1/2)^(n-1)

Then the 3rd term is a(3) = -5(1/2)^(3 - 1), or a(3) = -5(1/2)^2 = -5/4 = -1.25

What are the critical values for a two-tailed test with a 0.01 level of significance when n is large and the population standard

Sunny_sXe [5.5K]

For a two-tailed test we need to halve 0.01, giving 0.005. Then we need to sutract 0.005 from 0.5, giving 0.5 - 0.005 = 0.495. Looking up the p value of 0.495 in an inverse normal probability table we obtain the value z = 2.5758. Therefore the critical values are -2.5758 and 2.5758.

Solve for z. z−49−13=59 Enter your answer in the box. z=

REY [17]

Hello there!

Solve for z.

$z-49-13=59$

Explanation

↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by the numbers.

$-49-13=-62$

$z-62=59$

Then you add by 62 from both sides of the equation.

$z-62+62=59+62$

Simplify it should be the correct answer.

$z=121$

Answer⇒⇒⇒⇒z=121

Hope this helps!
