What is the answer choices?
Answer:
The cost of large drinks are $5 and the small drinks are $3.
Explanation:
5+5+5+3+3=21
2x5=10 4x3=12 10+12=22 OR (2)5+(4)3)=22
Answer:
<em>A normal distribution</em> is a general distribution that represents any normally distributed data with any possible value for its parameters, that is, the mean and the standard deviation. Conversely, <em>the standard normal distribution</em> is a specific case where the mean equals zero and the standard deviation is the unit. That is why we can refer to <em>a normal distribution</em> and <em>the standard normal distribution</em>.
Step-by-step explanation:
We have to remember that <em>a normal distribution</em> has two parameters that define it, namely, <em>the mean</em> and <em>the standard deviation</em>, and there are, theoretically, infinite possible means and standard deviations, so we tell about <em>a </em>normal distribution in general.
Conversely, <em>the</em> standard normal distribution is <em>a normal distribution</em> with a mean = 0 and a standard deviation = 1, and we also have to remember that is possible to 'convert' or 'transform' any raw score from any normally distributed data into a z-score to find its probability using <em>the</em> standard normal distribution. The formula for a z-score is as follows:
Where

.
In other words,<em> the standard normal distribution</em> is a specific case for normally distributed data whose values are standardized or represent distances from the mean in standard deviations units, and thanks to this, we can find any associated probability with these values for any possible normal distribution (see the graph below).
The derivitive of sec(x) is sec(x)tan(x)
find the slope at pi/3
sec(pi/3)=2
tan(pi/3)=√3
sec(x)tan(x) at x=pi/3 is 2√3
for slope=m and a point is (x1,y1)
the equation is
y-y1=m(x-x1)
slope=2√3
point=(pi/3,2)
equation is
y-2=2√3(x-pi/3)

Step-by-step explanation:
To construct tangent line to a circle based on two main properties of tangent line and inscriber triangle of circle
1. A line is tangent to a circle when it intersects the circle in one point. At that point, the radius of the circle forms a right angle with the tangent line. If the radius forms a right angle with the tangent line, <u>then the segment OP becomes the hypotenuse of the right triangle.</u>
2. a triangle inscribed in a circle having a diameter (OT) as one side is a right triangle.
Construction:
1. connect P and circle center "O"
2. construct perpendicular bisector of PO --- AB, Intersect M will be the center of new circle and its radius is MP
3. With the center of "M" and radius MP: construct a circle and intersect original circle at "T" and "T'"
4. PT and PT' are the tangent lines
