Answer:
CI = 29.8 ± 3.53
Critical value is z = 2.58
Step-by-step explanation:
First of all let's find margin of error. It is given by the formula;
ME = zσ/√n
We are given;
Standard deviation; σ = 3.62
Sample size; n = 7
Mean; x¯ = 29.8
Now, z-value for 99% Confidence level is 2.58
Thus;
ME = (2.58 × 3.62)/√7
ME = 3.53
CI is written as;
CI = x¯ ± ME
CI = 29.8 ± 3.53
Critical value is z = 2.58
Answer: 6.5<6.55
Step-by-step explanation: Because you add the zero to the 6.50 but it’s still less than 6.55.
The true statement is Line MK is the perpendicular bisector of LN and ML is ≅ MN.
<h3>What is perpendicular?</h3>
Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Given:
Δ LMN and Δ LKN are connected at side LN.
As per the information,
Line MK is the perpendicular bisector of LN. and ML ≅ MN.

Answer:24
Step-by-step explanation:
Answer:
Step-by-step explanation:
we are given equation as
Since, we have to solve it by using complete square
so, firstly we will complete square
and then we can solve for x
step-1:
Factor 2 from both sides
step-2:
Simplify it
step-3:
Add both sides 3^2
now, we can complete square
step-4:
Take sqrt both sides
step-5:
Add both sides by 3
we get
