Answer:

6x -7 units

Step-by-step explanation:

Let c represent the length of the third side. The perimeter is the sum of the three side lengths.

P = a + b + c

(17x -5) = (3x +5) +(8x -3) +c

17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms

6x -7 = c . . . . . . . . . . . . . . subtract 11x+2

The third side is 6x -7 units.

Find the P- value for the hypothesis test with the standardized test statistic z. Decide whether to reject H 0 for the level of

kkurt [141]

Answer:

Option B) 0.1032; fail to reject $H_0$

Step-by-step explanation:

We are given the following information in the question:

We used two tailed z-test to perform the hypothesis.

$z_{\text{stat}} = -1.63$

Level of significance, α = 0.05

We have to calculate the p-value.

We calculate the p-value from the normal standard z-table.

p-value = 0.1032

Since,

p-value > Level of significance

We fail to reject the null hypothesis and accept it.

Option B) 0.1032; fail to reject null hypothesis

If a sequence of 8 consecutive odd integers with increasing values has 9 as its seventh term. What is the sum of the terms of th

klemol [59]

Answer:

$Sum = 32$

Step-by-step explanation:

Given

Sequence = Consecutive Odds

$T_7 = 9$

Required

The sum of the terms

A sequence of odd number has a difference of 2. So, the sequence is represented as:

$S = \{-3,-1,1,3,5,7,9,11\}$

Add up all terms in the sequence

$Sum = -3-1+1+3+5+7+9+11$

$Sum = 32$
