Answer:

1.3344

Step-by-step explanation:

Given is the rainforest data.

Let X be the random variables

Then X has mean as 7 and variance as 12.405

SD of X = square root of variance = 3.522

We know that

Z = \frac {X-\mu}{\sigma}\\=\frac{11.7-7}{3.522} \\=1.3344

Z value when x = 11.7 is +1.3344

Answer:

Mean B =μ= 7

Standard Deviation =A=σ ≈ 3.522

Variance =σ²=12.405

X=Score=Data Point=11.7

As, Z=\frac{X- B}{A}

z-score for the Score 11.7

=\frac{11.7-7}{3.522}\\\\=\frac{4.7}{3.522}\\\\Z=1.3344

Which choices are correct when determining the distance between −56 and 69?
Gnesinka [82]

The choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units

<h3>How to determine the choices that are correct when determining the distance between −56 and 69?</h3>

The endpoints are given as

−56 and 69

The distance between the endpoints is calculated using

Distance = |Difference between  endpoints|

So, we have:

Distance = |-56 - 69|

Evaluate

Distance = 125

Hence, the choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units
