Z-score is computed by the equation below,
z-score = (x - μ) / σ
where x is the data point, μ is the mean and σ is the standard deviation. Substituting the known values,
z-score = (28,000 - 34,000) / $4000
z-score = -1.5
N<−1.6 repeating is the answer

Let's solve your inequality step-by-step.
5>0.6(10+n)
Step 1: Simplify both sides of the inequality.
5>0.6n+6
Step 2: Flip the equation.
0.6n+6<5
Step 3: Subtract 6 from both sides.
0.6n+6−6<5−6
0.6n<−1
Step 4: Divide both sides by 0.6.
0.6n
0.6

Answer: 2x=74
Step-by-step explanation:
Every triangle is 180 degrees.
so you will take 180-32= 148
then with that you will add up the x's and there are 4...
so then you will take 148/4 and get the answer of...
148/4=37
x=37
but it asked for 2x
37*2
2x=74
final answer is 74
T=34.34
explanation: solve for t by simplifying both sides of the equation, then isolating the variables.
Step-by-step explanation:
3 tan 2x - 4 tan 3x = tan² 3x * tan 2x
3 (tan 2x - tan 3x) = tan 3x + tan² 3x * tan 2x
= tan 3x (1 + tan 3x * tan 2x)
3 (tan 2x - tan 3x)/(1 + tan 3x * tan 2x) = tan 3x
3 * (- tan x) = tan 3x
-3tanx = (3 tan x - tan³ x) / (1 - 3 tan² x)
3 - tan² x = - 3 + 9 tan² x
tan x = + √3 /√5 or - √3/√5
