Select two choices: one for the centers and one for the spreads. O A. Centers: The sea turtles have a lower median age than the sharks. B. Spreads: The ages of the sea turtles are more spread out. O C. Centers: The sea turtles have a greater median age than the sharks. O D. Spreads: The ages of the sharks are more spread out
Answers
Options C and D.
The median age of the Sea turtles is 55 while the median age of the sharks is 30, thus validating OPTION C
We can get the ranges of the two distributions to be:
Sea Turtles: 65 - 45 = 20
Sharks: 55 - 10 = 45
Sharks have a larger range, validating OPTION D

40. Circle A has a radius 4 inches. Is each statement about circle A true?
Answers
The first statement is about the diameter of the circle.
The diameter of a circle is always the double of its radius.
So if circle A ras a radius of 4 inches, its diameter is:
[tex]\text{diameter}=2\cdot\text{radius}=2\cdot4=8\text{ inches}[/tex]So the first statement is true (YES)
The second statement is about the area of the circle. The area of a circle is given by the following equation:
[tex]Area=\pi\cdot r^2[/tex]If the radius of the circle is 4 inches, we have:
[tex]\text{Area}=\pi\cdot4^2=16\pi[/tex]So the second statement is also true (YES)
The third statement is about the volume of a cylinder with a height of 6 inches and the circle A as the base. The volume of a cylinder is given by the equation:
[tex]\text{Volume}=\pi\cdot r^2\cdot h[/tex]Using the radius = 4 inches and the height = 6 inches, we have:
[tex]\begin{gathered} \text{Volume}=\pi\cdot4^2\cdot6 \\ \text{Volume}=\pi\cdot16\cdot6=96\pi \end{gathered}[/tex]The volume is not 64pi, so this statement is false (NO).

We are given a question about factory plants making TV panels. The following information holds.
Plant A produces twice as many panels as plant B. This can be expressed mathematically as:
[tex]A=2B[/tex]Also, 2% and 3% of the TV panels from Plant A and Plant B are defective, and both plants produced a total of 490 defective panels. This can be expressed mathematically as:
[tex]\frac{2A}{100}+\frac{3B}{100}=490[/tex]We can clearly see that we have derived two equations. We will substitute the first equation in the second equation to get the number of panels Plant B produced.
[tex]\begin{gathered} \frac{2(2B)}{100}+\frac{3B}{100}=490 \\ \frac{4B}{100}+\frac{3B}{100}=490 \\ \frac{7B}{100}=490 \\ \text{Cross multiply} \\ 7b=490\times100 \\ B=\frac{490\times100}{7} \\ B=70\times100 \\ B=7000 \end{gathered}[/tex]Therefore, the number of panels that plant B produced is:

Answers
the Part a. Compute f(0). We have to evaluate the function for x = 0.
[tex]f(0)\text{ = 2(0) - 7 = 0 - 7 = -7}[/tex]Therefore, f(0) = -7.
Part b. Solve f(x) = 0.
[tex]f(x)=\text{ 2x - 7 }=\text{ 0}[/tex]To solve the equation 2x - 7 = 0, we have to add 7 to both sides of the equation, and then dividing the equation by 2:
[tex]2x\text{ - 7 + 7 = 7 }[/tex][tex]2x\text{ = 7 }\Rightarrow x\text{ = }\frac{7}{2}[/tex]So, x = 7/2.
Part c.
Part a tells us that the graph of the function is evaluated in zero, the value for the function is -7. When x = 0, the value for y = -7. This is the intercept of the linear function.
Part b tells us that when y = 0, the value for x = 7/2.
The line passes through points (0, -7) and (7/2, 0). These are the points on y-axis and x-axis, respectively.

Take the 1st angles.
∠5 and ∠6 are linear pairs.
A linear pair of angles is formed when two lines intersect at a single point. If the angles follow the spot where the two lines come together in a straight line, they are said to be linear. In a pair of linear equations, the sum of the angles is always 180°.
Take the 2nd angles.
∠3 and ∠2 are vertically opposite angles.
When two straight lines collide at a particular vertex, they create angles that are perpendicular to one another vertically. Angles that are perpendicular to one another vertically are equal. These are occasionally referred to as vertical angles.
Take the 3rd angles.

1 seagull eats 2.5 pounds of garbage.
Explanation:
First, we need to draw the point (4, 10) on the graph because 4 seagulls eat 10 pounds of garbage. Then, we need to draw a line that passes through this point, and through (0, 0). Finally, we need to identify the number of pounds of garbage when the number of seagulls is 1 or identify the point (1, k). So, we get:
Therefore, the value of k = 2.5 is the constant of proportionality and tell us the number of pounds of garbage that each seagull eat.
So, the graph of the line shows that the value of k is the y-coordinate of the point where the x-coordinate is equal to 1. Also, k represents the slope of the line.

Write the following equation x2 +9y2 + 10x – 18y + 25 = 0 in vertex form.Identify the type of conic section and its direction.
Answers
The equation of the conic section is:
[tex]x^2+9y^2+10x-18y+25=0[/tex]Square terms are positive and have different coefficients. Then, we can say it is an ellipse.
To find the vertex form, we need to group x and y:
[tex](x^2+10x)+(9y^2-18y)+25=0[/tex]The grouped terms of y can be factored:
[tex](x^2+10x)+9(y^2-2y)+25=0[/tex]It will be convenient to group the 25 with the group of x, since we can have a perfect square trinomial (since the square root of 25 is 5, which is half ten):
[tex](x^2+10x+25)+9(y^2-2y)=0[/tex]We can factor the first goup:
[tex](x+5)^2+9(y^2-2y)=0^{}[/tex]Now, we can try to make another perfect square trinomila from the second term. We need a number whose square root multiplied by 2 gives us 2 (the coefficient of y) This number will be one. Then, we can sum 1 inside the parenthesis, but we need to substract 9 outside it in order not to alter the equation. (it is 9 because we added 1 inside a parenthesis that is multiplied by 9).
[tex](x+5)^2+9(y^2-2y+1)-9=0^{}[/tex]Now, we can factor the second group of terms and reorganize:
[tex](x+5)^2+9(y-1)^2=9^{}[/tex]Now, to get the equation in the vertex form, we need a 1 in the right side of the equation. Then, we can divide everything (both sides) by 9:
[tex]\frac{(x+5)^2}{9}+(y-1)^2=1[/tex]The equation of the ellipse is now on its vertex form. Since the number dividing the x term (9) is higher than the number dividing the y term (1) we can say that the direction of the ellipse is horizontal. It´s longer axis is parallel to the x axis of the plane.
A SHADED REGION IS DESCRIBED BY THE FOLLOWING INEQUALITIES:X> OR EQUAL 0 , Y> OR EQUAL 0 , X+2Y< OR EQUAL TO 4 , X-Y< OR EQUAL 1 WHAT ARE ITS CORNER POINTS?
Answers
Its corner points (0, 0), (2, 1), (0, 2), (1, 0)
From the question, we have
All the points should be positive, as we can see after carefully examining the equation.
There are two approaches to approach this problem. The first is to solve the equations, create a graph, and make a decision.
The alternative is to just plug the points into the equations and check to see if the conditions are met; this method is quicker for tests with MCQs.
As a result, option B is correct.
Inequalities:
In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than. The different inequality symbols, properties, and methods for resolving linear inequalities in one variable and two variables will all be covered in this article along with examples.
