the graph shows the total number of comic books in brandon's collection at the end of every month for the year 2014
Answers
Answer:
B
Step-by-step explanation:
The slope of the line of best fit is {m} = 3.
What is mean, median and mode in statistics?Mean : The "average" number; found by adding all data points and dividing by the number of data points.Median : The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).Mode : The most frequent number—that is, the number that occurs the highest number of times.Given is the the graph shows the total number of comic books in Brandon's collection at the end of every month for the year 2014. The line of best fit for the data is given by the equation → y = 3x + 22, where {y} is the total number of comic books in Brandon's collection {x} months after the beginning of the year 2014.
The given equation is -
y = 3x + 22
The general equation of the line is -
y = mx + c
where -
{m} is slope
{c} is y - intercept.
The slope of the line of the best fit would be -
{m} = 3
Therefore, the slope of the line of best fit is {m} = 3.

Answer:
Pretty sure its -3,-2. not 100% sure but I am good at coordinates.
Step-by-step explanation:
Because you just go by the X axis first so that's -3 and then you go by the Y axis which is up and down and that would be -2. So its -3,-2.

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density
Answers
Answer:
The density of the prism is 0.453 kilograms per cubic meter.
Step-by-step explanation:
Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.
Besides, the volume of the right angle triangle prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)
Where:
[tex]b[/tex] - Breadth of the base, in meters.
[tex]h[/tex] - Height of the base, in meters.
[tex]l[/tex] - Length of the base, in meters.
If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:
[tex]V = 7.5\,m^{3}[/tex]
[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]
The density of the prism is 0.453 kilograms per cubic meter.

Answers
Answer:
Part A & B
Step-by-step explanatPart A:
f(x) = 4x ^ 2 - 7x - 15
0 = 4x ^ 2 - 7x - 15
a = 4, b = -7, c = -15
a x c = -60
-12 x 5 = -60
-12 + 5 = -7
(4x + 5)(4x - 12)
4x ^ 2 - 12x I + 5x - 15
4x(x - 3) + 5(x - 3)
(x - 3)(4x + 5)
x = 3 x = -1.25 or -5/4
Part B:
Minimum point
(x1 + x2)/2
(3 -1.25)/2 = 0.875
f(x) = 4x ^ 2 - 7x - 15
f(0.875) = 4(0.875) ^ 2 - 7(0.875) - 15
f(0.875) = 3.06 - 6.125 - 15
f(0.875) = -18.065ion:

Helene invested a total of $1,000 in two simple-interest bank accounts. One account paid 8% annual interest; the other paid 9% annual interest. The total amount of interest she earned after one year was $86. Enter and solve a system of equations to find the amount invested in each account. Enter the interest rates in order as given in the problem. (Hint: Change the interest rates into decimals first.)
at 9%.
Answers
Answer: -600 and 1600 were invested into the two accounts.
Step-by-step explanation:
x = amount invested in the first account.
y = amount invested in the second account.
You start off with this equation
[tex]x + y = 1000[/tex]
[tex]0.08x + 0.09y=86[/tex]
Subtract both sides by y.
[tex]x=1000-y[/tex]
Subsitude 1000 - x for x for the second equation.
[tex]0.08(1000-y)+0.09y=$86[/tex]
Use the distributive property to solve for y.
[tex]80-0.08y+0.09y=86[/tex]
[tex]80-0.01y=86[/tex]
[tex]6=-0.01y[/tex]
[tex]=-600[/tex]
Subsitude -600 for y in the first equation and solve for x.
[tex]x-600=1000[/tex]
[tex]x=1600[/tex]
-600 and 1600 were invested into the two accounts.

Triangle E F G is shown. Angle G F E is a right angle. The length of G F is 3 and the length of E F is 4.6. Which equation could be used to find m∠E in △EFG? m∠E = cos–1(StartFraction 3 Over 4.6 EndFraction) m∠E = cos–1(StartFraction 4.6 Over 3 EndFraction) m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction) m∠E = tan–1(StartFraction 4.6 Over 3 EndFraction)
Answers
Answer:
m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)
Step-by-step explanation:
Given the following
m<GFE = 90 degrees
GF = 3
EF = 4.6
The side opposite to m<E is GF
Adjacent side is EF
Using the SOH CAH TOA identity
tan theta = opp/adj
tan m<E =GF/EF
Substitute the given values
tan m<E = 3/4.6
m<E = tan^-1 (3/4.6)
Hence the required result is m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)

8x2 – 4x = 363
Answers
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4

The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.
