If there are three black, four white, two blue, and four gray socks in a drawer, what would be the probability of picking a blue sock? Round your answer to the nearest tenth.15.4%25%22%15.38%
The formula for determining probability is expressed as
Probability = number of favorable outcomes/number of total outcomes
number of favorable outcomes = number of blue socks = 2
number of total outcomes = number of all socks = 3 + 4 + 2 + 4 = 13
Thus, the probability of picking a blue sock is
2/13 = 0.1538
Converting to percentage, we would multiply by 100. We have
0.1538 x 100
= 15.38%

between 1993 and 1996 there where 6545 injured horses find the ratio of injuries per year
First, we have to know the total number of years between 1993 and 1996. If we subtract, we find the there are 3 years in between.
Now, we divide the total number of injured horses by the total numbers of years.
[tex]r=\frac{6545}{3}=2,181.7[/tex]However, we can't round to 2,182 because horses are not incomplete.
Therefore, the total number of injured horses per year is 2,181.19.) A.) use the idea of walking and turning around a shape to determine the sum of the exterior angles of the quadrilateral and figured 10.93. In other words, determine e + f + g + h. Measure with a protractor m to check that your formula is correct for this quadrilateral. B.) Will there be a similar formula for the sum of the exterior angles of Pentagon ‘s, hexagons, heptagon ‘s, octagons, and so on? Explain.C.) using your for your formula for the sum of the exterior angles of a quadrilateral, reduce the sum of the interior angles of the quadrilateral.in other words, find a+b+c+d, as pictured in figure 10.93. Explain your reasoning. Measure with a protractor to verify that your formula is correct for this quadrilateral.D.) based on your work, what formula would you expect to be true for the sum of the interior angles of a pentagon? what about for a hexagon? What about for a polygon with 10 sides? Explain briefly
A) To find the external angles of the quadrilateral we will walk around the shape measuring every turn we take. We will start on the A point, rotate clock-wise and move in the direction of point "B", when we get there we will rotate clock-wise again and walk to the direction of point "C". When we do get to the point C we will notice that we rotated 180 degrees in relation to the initial position we had in point A. Moving forwars we will now rotate clockwise and go to the poind D, rotate clock-wise again when we get there, performing all the rotations needed. We will notice that we have the same orientation from the beginning, this means that we rotated 360 degrees. In other words the sum of the external angles of the quadrilateral is 360 degrees.
B) Yes, any regular polygon will have the sum of its external angles equal to 360 degrees.
C) The internal and external angles are suplementary. This means that the sum of these angles must be equal to 180 degrees, therefore:
[tex]\begin{gathered} external\text{ = 180-internal} \\ e+f+g+h=360 \\ (180-a)+(180-b)+(180-c)+(180-d)=360 \\ a+b+c+d=180+180+180+180-360 \\ a+b+c+d=4\cdot180-2\cdot180 \\ a+b+c+d=(4-2)\cdot180 \\ a+b+c+d=2\cdot180=360 \end{gathered}[/tex]Since each external angle is the same as "180 degrees" minus the internal angle that is close to it we can represent the sum of the external angles as 360 degrees and use the mentioned relation to convert them into internal angles. If we isolate them as a sum we will find the value of the sum of the internal angles.
D) If we look at the fith line from the solution above we will notice that the sum of internal angles is represented by "(4-2)*180", the polygon had "4" sides. This means that for one that is 5 sides we should expect that it would be "(5-2)*180" and so on. So the formula is:
[tex]\text{internal = (n-2)}\cdot180[/tex]Where "n" is the number of sides of the polygon.

To find equivalent ratios to 3/5, we just have to multiply each part by 4, 2, and 3.
[tex]\begin{gathered} \frac{3\cdot4}{5\cdot4}=\frac{12}{20} \\ \frac{3\cdot2}{5\cdot2}=\frac{6}{10} \\ \frac{3\cdot3}{5\cdot3}=\frac{9}{15} \end{gathered}[/tex]Hence, the right answers are A, B, and F.What E is. if E=2 when W=15, find E when W=10
Since the elongation E varies directly with the weight W, they are related as follows
[tex]E=kW[/tex]where k is the constant of proportionality. In order to find k, we can substitute the given values, that is, when E=2, W=15, then we have
[tex]2=k\cdot15[/tex]Then, k is given as
[tex]k=\frac{2}{15}[/tex]Therefore, our formula for any E and W is
[tex]E=\frac{2}{15}W[/tex]Now, in order to find E in the second case, by replacing W=10, we get
[tex]E=\frac{2}{15}(10)[/tex]which yields
[tex]E=\frac{20}{15}=\frac{4}{3}[/tex]Therefore, the answer is
[tex]E=\frac{4}{3}[/tex]1) The expression 5p represents the total price of buying 5 movie tickets. • What do the parts of the expression 5p represent? ) The variable p represents the ticket price The number 5 represents the number of tickets Today there is a discount of $10 off a purchase of 5 or more movie tickets. Which expression can you use to find the total price of 5 movie tickets after the discount? 10p + 5 5p - 10 10p - 5 5p + 10
Solution
The expression 5p represents the total price of buying 5 movie tickets. • What do the parts of the expression 5p represent?
The variable p represents the ticket price The number 5 represents the number of tickets
For this case the correct answer would be:
5p -10

Determine the smallest integer value of x in the solution of the following inequality.3x + 4> -18
We have the following inequality:
3x + 4 > -18
Subtracting 4 from both sides we got:
3x > -22
Dividing both sides by 3 we got:
x > -22/3
Since -22/3 is between -7 and -8 and x must be equal or greater than -22/3, the smallest integer value in the solution of the inequality is -7 (note that -8 isn't part of the solution)
Find the better buy:14 oz of doritos for $2.50 or 22 oz of doritos for $3.99.Make sure you round everything up to the nearest cent
Answer:
Both
Explanation:
To determine the better buy, find the unit price for each of the purchase:
[tex]\begin{gathered} \text{14 oz of doritos }\cos ts\text{ \$}2.5 \\ \text{Unit Price=}\frac{\text{2.5}}{14} \\ =\$0.179\text{ per oz} \\ \approx\$0.18\text{ per oz} \end{gathered}[/tex]Similarly:
[tex]\begin{gathered} \text{22 oz of doritos }\cos ts\text{ \$}3.99 \\ \text{Unit Price=}\frac{\text{3}.99}{22} \\ =\$0.181\text{ per oz} \\ \approx\$0.18\text{ per oz} \end{gathered}[/tex]Therefore, to the nearest cent, both are equal buys since they have the same value.
How do you figure out what the order pairs are in this equation? 2x-2=y
Equations express relationships between variables and constants. The solutions to two-variable equations consist of two values, known as ordered pairs, and written as (a, b) where "a" and "b" are real-number constants. An equation can have an infinite number of ordered pairs that make the original equation true.
Here, the given equation is,
[tex]2x-2=y[/tex]Rewriting this equation in terms of x, we have,
[tex]\begin{gathered} 2x-2=y \\ 2x=y+2 \\ x=\frac{y+2}{2} \end{gathered}[/tex]So, now creating a table, with the values, we get the ordered pair. For example, let us take x as 1, then ,
[tex]\begin{gathered} 1=\frac{y+2}{2} \\ 2=y+2 \\ y=0 \end{gathered}[/tex]So, (1,0) is an ordered pair in this equation.
If x =0,
[tex]y=0-2=-2[/tex]So the pair is, (0,-2).

What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The points are,
(0, - 1) and (5, 3)
Now,
Since, The slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is;
m = (y₂ - y₁) / (x₂ - x₁)
So, The slope of the line passing through the points (0, - 1) and (5, 3) is;
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - (-1)) / (5 - 0)
m = (3 + 1) / 5
m = 4/5
And, The y - intercept is at x = 0
Thus, The slope will be 4/5.
And, The y - intercept will be (0, - 1)
