Answers
The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.
We want to calculate the probability the student is a male given that it's a sophomore. Since we already know the student is a sophomore, the possible outcomes are only male sophomores(6) and female sophomores(4) and the favourable outcomes are the male sophomores(6), therefore, this probability is:
[tex]P(Male|Sophomore)=\frac{6}{6+4}=\frac{6}{10}=\frac{60}{100}=60\%[/tex]The probability the student is a male given that it's a sophomore is 60%.

1 ptsQuestion 5Jane started jogging 5 miles from home, at a rate of 2 mph. Write the slope-intercept form of an equation for Jane's position relative to home.
Answers
Answer
[tex]y=2x+5[/tex]SOLUTION
Problem Statement
The question wants us to model the distance Jane is from her home given her initial starting point (5 miles from home) and her speed (2 mph)
Explanation
To solve the question, we simply need to model her jogging using the equation of a line.
The general equation of a line is given as:
[tex]\begin{gathered} y=mx+c \\ \text{where,} \\ m=\text{slope}=\text{this represents Jane's speed} \\ c=y-\text{intercept}=\text{this represents her initial position from her home} \\ x=\text{time taken for Jane to move} \\ y=\text{Jane's final position after moving for time, x} \end{gathered}[/tex]We have been told that her speed is 2 mph. Thus, m = 2. We have also been given her initial position from her house to be 5 miles.
Jane starts jogging 5 miles from her home, thus, her position relative to her home will continue to increase as she jogs on at 2 mph. Thus, c = 5 and NOT -5.
This means we can write the equation for her position is:
[tex]\begin{gathered} m=2,c=5 \\ \therefore y=2x+5 \end{gathered}[/tex]Final Answer

f(x); g(x)=f(x)-a, the function is translated a units down.

Ordered pairs are written in the form (x, y), this means, whichever ordered pair is a solution, when inserted into the system of inequalities, should be true.
This means that the values of x and y must be true for both inequalities in the system.

What is the length of the side of an equilateral triangle if the height is 9√3
Answers
An equilateral triangle is a triangle were all the sides have the same measurement, and all the angles are the same(60º).
The height of an equilateral triangle divides the triangle into two equal right triangles. The height represents the oposite side of the angle of 60º, and the hypotenuse has the length of the side of the equilateral triangle, if we find the hypotenuse we have our answer.
Using trigonometric relations on the right triangle, we can find the value for the hypotenuse. The ratio between the opposite side to an angle and the hypotenuse is equal to the sine of this angle. If we call the hypotenuse as h, we have the following relation
[tex]\sin (60^o)=\frac{9\sqrt[]{3}}{h}[/tex]The sine of 60º is a known value
[tex]\sin (60^o)=\frac{\sqrt[]{3}}{2}[/tex]Then, combining both expressions, we have

[tex]\begin{gathered} \frac{9\sqrt[]{3}}{h}=\frac{\sqrt[]{3}}{2} \\ \frac{9}{h}=\frac{1}{2} \\ \frac{h}{9}=2 \\ h=18 \end{gathered}[/tex]The length of the side of an equilateral triangle if the height is 9√3 is equal to 18.

According to theoretical probability, Avery would have expected to land on heads twite as many times as she did experimentally.D. According to theoretical probability, Avery would have expected to land on heads 12 more times than she did experimentally.
Answers
In order to determine the best description, first count the number of times for heads h and tails t.
Based on the given information, the number of heads was h = 6 and the number of tails was t = 18.
The theoretical probability in this case results in a 50% of probability for both events, that is, for 24 times at which the coin was flipped, 12 would be tail and 12 would be head.
Then, based on the previous explanation, you can conclude that:
C. According to theoretical probability, Avery would have expected to land on heads twite as many times as she did experimentally.

The diagram shows two parallel lines cut by a transversal. One angle measure is shown.do8abº5499coFind the values of a, b, c, d, e, f, and g.
Answers
This question applies the rules of angles on a plane. The transversal that cuts the two parallel lines is a decisive one. From there you can determine which angles are opposite, alternate and so on.
Obeserve carefully that angle 54 and angle a lie on a straight line.
"Angles on a straight line sum up to 180 degrees."
Therefore,
Angle 54 + Angle A = 180
54 + A = 180
Subtract 54 from both sides of the equation
54 - 54 + A = 180 - 54
A = 126
Also note that;
"Opposite angles are equal in size."
Angle B is opposite to angle 54
Therefore angle B is 54 degrees.
Note also that angle C is opposite to angle A, therefore angle C equals angle A and that makes angle C = 126
If the two parallel lines are cut by a transversal, then it makes it easy to identify alternate angles. Alternate angles are formed on the inner sides of the two parallel lines but on the opposites sides of the tranversal. If you observe VERY CLOSELY, it usualltakes the form of a Z shape. You can equally determine alternate angles on the outer parts of the parallel lines in which case it becomes "exterior alternate angles."
"Alternate angles are equal."
Observe carefully and you'll see that angle B and angle D are interior alternate angles. That means B equals to D and therefore angle D = 54 degrees.
Similarly, angle A and angle G are alternate angles. Therefore angle G = 126 degrees.
Also angle F is opposite to angle D, and therefore angle F = 54 degrees.
Angle E is opposite to angle G, therefore angle E = 126 degrees

The average rate of change of function f(x) over the interval 12 ≤ x ≤ 21 is 2/3
We use the formula of average rate of change of function over the interval [x1, x2],
r = [f(x2 - f(x1)]/ (x2 - x1)
We need to find the average rate of change of function f(x) over the interval 12 ≤ x ≤ 21
r = [f(21) - f(12)] / (21 - 12)
r = (31 - 25) / 9
r = 6/9
r = 2/3
Therefore, the average rate of change of function f(x) over the interval 12 ≤ x ≤ 21 is 2/3
