Answer: a≈6,1.
Step-by-step explanation:
The sine theorem states:
, ⇒
m∡A=180°-(m∡B°+m∡C°)
=180°-(68°+76°)
=180°-144°
=36°. ⇒
Good luck an' have a nice day!
Answer:
After how many days will the tank need to be refilled?
Step-by-step explanation:
To answer our question, we first need to figure out what d represents. d is multiplied by 0.035, which is how much the water level decreases daily. Since it decreases daily, the overall amount it decreases depends on how many days have passed. It is logical then to deduce that d represents days (also days starts with d, so we know we're on the right track haha).
The equation equals to 4, the water level at which the tank must be refilled, so we know we are looking for d when the tank must be refilled.
It is not a function because functions can’t have the same x axis
Domain is input so x axis So list all the x axis
Range is output so y axis and list all y axis
Answer:
The lower end of the interval is above 0.5, which means that it provides evidence that a majority of visitors to Niagara Falls are from the United States
Step-by-step explanation:
We want to see if the majority of Niagara Falls visitors are from the United States.
Looking at the confidence interval
We have to see if the lower end of the interval is higher than 0.5.
In this question:
The 95% confidence interval to estimate the true proportion of visitors to Niagara Falls that are from the United States was (0.5216, 0.6784).
The lower end of the interval is above 0.5, which means that it provides evidence that a majority of visitors to Niagara Falls are from the United States
