You have two numbers. If you double the first number and add it to the second number, the sum is 10. An equation to represent this situation could be: 2x + y = 10 1) Plot at least five points on this coordinate plane that make the statement and your equation true. What do you notice about the points you have plotted? 2) Using a different color, plot 3 point in the same coordinate plane that do not make the equation true.
Answer:
(a) See attachment 1
All points lie on the same line
(b) See attachment 2
Step-by-step explanation:
Given
[tex]2x + y = 10[/tex]
Solving (a): Plot 5 points that make the equation, true
First, we calculate the points
Make y the subject
[tex]y = 10 - 2x[/tex]
[tex]x = 0 \to y = 10 - 2* 0 = 10[/tex]
[tex]x = 1 \to y = 10 - 2* 1 = 8[/tex]
[tex]x = 2 \to y = 10 - 2* 2 = 6[/tex]
[tex]x = 3 \to y = 10 - 2* 3 = 4[/tex]
[tex]x = 4 \to y = 10 - 2* 4 = 2[/tex]
So, we will plot the following points
[tex](0,10)\ (1,8)\ (2,6)\ (3,4)\ (4,2)[/tex]
See attachment 1
Notice that all points lie on the same line
Solving (b):
Point (5,7) does not make the equation true, and that is why it lies outside the line
See attachment 2

Which of the following r-values represents the strongest correlation?
A. 0.55
B. 0.65
C. 0.35
D. 0.45
Answer:
0.65
Step-by-step explanation:
The r-value option (B) 0.65 represents the strongest correlation.
What is the correlation coefficient?The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.
For the given situation,
We need to determine the r-value that represents the strongest correlation.
The relationship between two variables is generally considered strong when their r value is larger than 0.7.
Among the options, 0.65 is near to 0.7, so it has strongest correlation.
Hence we can conclude that the r-value option (B) 0.65 represents the strongest correlation.

Answer:
=98m^2
Step-by-step explanation:
11×4=44
9×6=54
44+54=98
=98m^2
Factor: 0.25x^2 - 0.16y^4
0.25x^2 - 0.16y^4
Both terms are perfect squares so use the difference of squares formula
A^2 - b^2 = (a+b)(a-b) where a = 5x and b = 4y^2
Answer is 0.01(5x + 4y^2)(5x-4y^2)
Answer:
Solution given:
0.25x^2 - 0.16y^4
[0.5x]²-[0.4y²]²
[Note: Using formula: x²-y²=(x+y)(x-y)]
(0.5x+0.4y²)(0.5x-0.4y²) is a required answer.

Answer:
3.2
Step-by-step explanation:
Answer: 3.3
Step-by-step explanation: To find x(adjacent)we need to know the length of the opposite ,and to do so we use the dimensions of the larger triangle,let's say A.
So using SOHCAHTOA
Sin=opposite÷hypotenus . Meaning
Opposite =hypotenus×sin
=9×sin31°
=4.635... which is rounded to 4.64.
Finding x
From tan=opposite÷adjacent
adjacent=opposite÷tan
=4.64÷tan55°
=3.2489.... which is rounded to 3.3

Choose all the conversion factors that relate cups to fluid ounces. 8fl oz1c 8c1fl oz 1fl oz8c 1c8fl oz 4fl oz2c
Answer:
[tex]1\ c = 8\ fl\ oz[/tex]
[tex]\frac{1}{8}\ c = 1\ fl\ oz[/tex]
[tex]\frac{1}{4}\ c = 2\ fl\ oz[/tex]
Step-by-step explanation:
The options are not properly formatted;
So, I will solve the question using general notations
Required
Conversion factors of cups and fluid ounces
Let
[tex]c = cup[/tex]
[tex]fl\ oz = fluid\ ounces[/tex]
In standard conversion
[tex]1\ c = 8\ fl\ oz[/tex]
Divide both sides by 8
[tex]\frac{1\ c}{8} = \frac{8\ fl\ oz}{8}[/tex]
[tex]\frac{1}{8}\ c = 1\ fl\ oz[/tex]
Multiply both sides by 2
[tex]2 * \frac{1}{8}\ c = 1\ fl\ oz * 2[/tex]
[tex]\frac{1}{4}\ c = 2\ fl\ oz[/tex]
A grain silo is built from two right circular cones and a right circular cylinder with internal measurements represented by the figure above. Of the following, which is closest to the volume of the grain silo, in cubic feet?
A) 261.8
B) 785.4
C) 916.3
D) 1047.2
Answer:
Step-by-step explanation: The volume of the grain silo can be found by adding the volumes of all the solids of which it is composed (a cylinder and two cones). The silo is made up of a cylinder (with height 10 feet and base radius 5 feet) and two cones (each with height 5 ft and base radius 5 ft). The formulas given at the beginning of the SAT Math section:
Volume of a Cone:
[tex]V=\frac{1}{3} \pi r^2h[/tex]
Volume of a Cylinder:
[tex]V=\pi r^2h[/tex]
can be used to determine the total volume of the silo. Since the two cones have identical dimensions, the total volume, in cubic feet, of the silo is given by
[tex]V_{silo} =\pi (5^2)(10)+(2)(\frac{1}{3})\pi (5^2)(5)=(\frac{4}{3})(250)\pi[/tex]
which is approximately equal to 1,047.2 cubic feet.
The final answer is D.
Solve the real-world situation by using the substitution method.

What is the sum of the measures of the exterior angles of the polygon shown below if necessary round to the nearest 10th
Answer:
24
Step-by-step explanation:
Number of sides = 15 (counted and it was a pain the a*s)
The total measure of the exterior angle = 360
= 360/15
= 24 degree
Each angle is measured 24 degree
The sum of the exterior angles of the polygon shown in the image is: 360°.
What is the Sum of Exterior Angles of a Polygon?Regardless of the number of sides or angles a polygon has, the sum of exterior angles of any polygon is always 360 degrees.
Thus, the polygon given has 15 sides, however, the sum of all its exterior angles will still give 360 degrees.
Therefore, the sum of the exterior angles of the polygon shown in the image is: 360°.
