Answer:
A radical function contains a radical expression with the independent variable (usually x) in the radian. Usually radical equations where the radical is a square root is called square root functions. An example of a radical function would be. y=√x. This is the parent square root function and its graph looks like.

Answer:
466.9 ft²
Step-by-step explanation:
The shape given is a trapezoid
Area of trapezoid = ½(a + b)*h
Where,
a and b are the two bases of the trapezoid,
h is the height of the trapezoid or the distance between the two bases
a = 33 ft
b = 25 ft
h = √(18² - (33 - 25)²)
h = √(18² - 8²)
h = √260
h = 16.1 (nearest tenth)
Find the area by plugging in the values into the formula
Area = ½(33 + 25)*16.1
Area = ½(58)*16.1
Area = 466.9 ft²
Answer:
The following display from a TI-84 Plus calculator presents a 99% confidence interval for a proportion.Fill in the blanks:
We are ____99%____ confident that the population mean is between ___0.385631____ and ___0.780609____.
c) 99%, 0.385631, 0.780609
Step-by-step explanation:
This is the only correct option, given the relevant population mean range. Option B is not correct as the population mean cannot range between 0 and 0.583120 as given by the option. Options 'a' and 'd' are not relevant to the question because they have 1% confidence level, instead of the stated 99% confidence level.
Answer:
Step-by-step explanation:
Given the data:
Weight ____Height
110 _______ 120
130 _______140
150 _______160
From the data given, we can conclude that that there exist a positive relationship between weight and height. As weight increases, the height increases and vice versa. The weight variable and height variable are positively correlated and thus an individual with a high weight value will have a high height value.
I would say that it might be B, or C, by looking at it a bit more
