Answer:
(-∞,∞)
(-∞,∞)
Step-by-step explanation:
When someone asks for the domain they're asking for all the possible x values of the equation. In this case there are no restrictions so x can equal any real number
When someone asks for the range they're asking for all the possible y values. There are no restrictions and therefore y can equal any real number
Answer:
-0.91
Step-by-step explanation:
Since the given question is
41x-6x=-23+9
x(41-6)=-23+9
And we are to make x the subject of formula by dividing both sides by 41-6
X=-23+9/41-6
X=-32/35
X=-0.91429~-0.91
Answer:
(A) 1100 and 1300 hours
Step-by-step explanation:
In a normal distribution, we can say that 68% of the values is between the range [µ-σ;µ+σ] with µ = the mean and σ is the standard deviation.
95% of the values are between the range [µ -2σ; µ+2σ] = [1100;1300]
99.7% of the values are between the range [µ -3σ; µ+3σ] = [1050;1350]
To find 75% of the values, we have to use the z-score
for 75% the Z-score = 1.15
This gives the range: [µ -Zσ; µ+Zσ] ⇒ [1200 - 1.15*50;1200+1.15*50] = [1142.5 ; 1257.5]
We can say that at least 75% (or more) is in the range [1100;1300]
