Final answer:
The element in group 15 and period 4 of the periodic table is Arsenic (As), which is classified as a metalloid due to its mixed properties of metals and non-metals.
Explanation:
The element that is found in group 15 and period 4 on the periodic table is Arsenic (As). Group refers to the vertical column and period refers to the horizontal row on the periodic table.
Arsenic belongs to the 'p-block' group of the periodic table and it is classified as a metalloid. This means it has properties of both metals and non-metals. For example, arsenic is brittle (like a non-metal) but can also conduct some electricity (like a metal).

What is a linear equation?
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
A bike rental company charges $50 for the first hour and $25 for each additional hour. Michael must spend no more than $200 on his bike rental for the day.
Let x be the number of hours. Then the linear equation will be
25x + 50 = 200
Simplify the equation, then we have
25x = 175
x = 7
The maximum number of hours that Michael can rent a bike is 7 hours. Then the correct option is D.

Answer: a) -0.94
Explanation:
The closer r gets to +1 or -1, the stronger the linear relationship will be.
If r is really close to +1, then we have a strong positive linear relationship. If r is close to -1, then we have a strong negative linear relationship.
Of the four choices given, we see that r = -0.94 is the closest to either endpoint mentioned. The next closest is r = 0.91
Put another way, we're looking for the r value that is furthest way from 0, but also that makes the inequality true. Choice A fits that description best.
Final answer:
The value of -0.94 represents the strongest relationship between the two variables in a given linear regression model.
Explanation:
The value of a correlation coefficient ranges from -1 to 1. The closer the value is to -1 or 1, the stronger the relationship between the two variables in a linear regression model. Therefore, the value of "-0.94" represents the strongest relationship among the given options. A negative correlation coefficient indicates an inverse relationship, meaning that as one variable increases, the other variable decreases.

Given:
The equation of the circle is
We need to determine the center and radius of the circle.
Center:
The general form of the equation of the circle is
where (h,k) is the center of the circle and r is the radius.
Let us compare the general form of the equation of the circle with the given equation to determine the center.
The given equation can be written as,
Comparing the two equations, we get;
(h,k) = (0,-4)
Therefore, the center of the circle is (0,-4)
Radius:
Let us compare the general form of the equation of the circle with the given equation to determine the radius.
Hence, the given equation can be written as,
Comparing the two equation, we get;
Thus, the radius of the circle is 8
