Answer:
z = -0.4.
Step-by-step explanation:
Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement 
of a normal random variable 
:
,
where
is the z-score of this measurement, - is the value of this measurement,
is the mean of the random normal variable, and
is the standard deviation (the square root of variance) of the random normal variable.
Let the length of a trout in this lake be 
inches.
.
, and
.
For this measurement, 
. Apply the formula to get the z-score:
.
Answer:
72
Step-by-step explanation:
Use PEMDAS
Parentheses
Exponent
Multiplication and Division (if it contains both, just go from left to right)
Addition and Subtraction (if it contains both, just go from left to right)
8 + (5)(4) − (6 + 10/2) + 55
8 + 20 − (6 + 10/2) + 55
28 − (6 + 10/2) + 55
28 − (6 + 5) + 55
28 − 11 + 55
17 + 55
72
To solve it step by step with PEMDAS:
Solve within the parentheses
6 + 10/2
10/2 = 5
6 + 5 = 11
Multiply/Divide
(5)(4) = 20
Add/Subtract
8 + 20 - 11 + 55 = 72
72
Answer:
infinite is the correct answer
Answer:
Step-by-step explanation:
<h3>Given GP</h3>
<h3>To find</h3>
<h3>Solution</h3>
<u>nth term formula</u>
- aₙ = a₁rⁿ⁻¹, where r- common ratio, n- number of the term
<u>We have</u>
- a₁ = -9
- r = 27/-9 = -81/27 = -3
<u>Find a₁₂</u>
- a₁₂ = (-9)*(-3)¹¹ = 1594323
Correct choice is B
