I will mark brainlest!!
Answer:
y = -9/8x +7
Step-by-step explanation:
We know two points on the line so we can find the slope
m = ( y2-y1)/(x2-x1)
m = ( -2 -7)/(8 -0)
= -9/8
We also know the y intercept which is 7
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -9/8x +7
Answer:
[tex]y=-\frac{9}{8}x+7[/tex]
Step-by-step explanation:
Slope-intercept form is y=mx+b
Use the formula for slope: m=(y2-y1)/(x2-x1)
m=(-2-7)/(8-0)
m=-9/8
The graph shows that b, the y-intercept, is at (0,7)
Therefore, the final equation is [tex]y=-\frac{9}{8}x+7[/tex]

trying to find rise and the run
Answer: rise is 4 and run is 5
Step-by-step explanation:
Answer:
down below
Step-by-step explanation:
To find the rise over run, you need to pick a point that intersects one of the axises. Then, you need to find a point that intersects the other axis. Third, you find the first point and begin moving up or down until you reach the height of the other point. From there, you count along that height line until you reach the second point. The number from counting on the y axis is the rise and the number from counting on the x axis is the run. So, you take the rise and put it over the run.
Hope this helps! :)

The difference between 1/3 of a certain number and 1/4 of the same number is 3.
What is the number?
24. 36. 48. 60. or 72?
Answer:
36
Step-by-step explanation:
Let the required number be x.
[tex] \frac{1}{3} \: of \: x = \frac{1}{3}x = \frac{x}{3} \\ \\ \frac{1}{4} \: of \: x = \frac{1}{4}x = \frac{x}{4} \\ \\ according \: to \: the \: given \: condition \\ \\ \frac{x}{3} - \frac{x}{4} = 3 \\ \\ \frac{4x - 3x}{3 \times 4} = 3 \\ \\ \frac{x}{12} = 3 \\ \\ x = 12 \times 3 \\ \\ \huge \red{ \boxed{ x = 36}}[/tex]
The number is 36.
Given that,
The difference between one-third of a certain number and one-fourth of the same number is 3.Here we assume the number be x.
Based on the above information, the calculation is as follows:
[tex]\frac{x}{3} - \frac{x}4} = 3 \\\\\frac{4x - 3x}{12} = 3\\\\x = 36[/tex]

Which expression is equivalent to -3\4 divided by (-8/12)
when 1/2 divided by (-8 / 12), it is equivalent to ( -3 /4)
Let an expression be 'x'
Given that, an expression must exist that is equivalent to -3/4 when divided by (-8/12).
This leads us to the conclusion that = x / (-8 / 12) = -3 / 4
It is equivalent to = x * (- 12 / 8) = -3 / 4
We get = x * (- 12 / 8) * (- 8 / 12) = -3 / 4 * (-8 / 12) by multiplying (- 8 / 12) on both sides.
We get = x = - 3/ 4 * (-8 / 12) by canceling like numbers.
x = 24 / 48
x = 1 / 2
Therefore, 1/2 divided by (-8 / 12) equals (-3 / 4).

Answer: -13w - 7
Step-by-step explanation:
-6w + (-8) + 1 + (-7w)
Combine the like terms
-8 + 1 = -7
-6w + (-7) + (-7w)
-6w + (-7w) = -13w
-13w + (-7)
However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7

What are collinear points?An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points are transparently collinear. If the points are in a line, then the points are collinear points.
Let A, B, and C be the collinear points. Then the condition of the collinear will be
AB + BC = AC
PQ = 2x + 8, QR = x + 11, and PR = 5x - 3. From the figure, the points P, Q, and R are the collinear points. Then we have
PQ + QR = PR
2x + 8 + x + 11 = 5x - 3
3x + 19 = 5x - 3
22 = 2x
x = 11
Then the line segment PR, PQ, and QR will be
PQ = 2 × 11 + 8
PQ = 22 + 8
PQ = 30
QR = 11 + 11
QR = 22
PR = 5 × 11 - 3
PR = 55 - 3
PR = 52
The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.

What is the standard deviation? Round your answer to two decimal places. s_x\approxs x ≈s, start subscript, x, end subscript, approximately equals \text{kg}kgstart text, k, g, end text
Answer:
The standard deviation of the weight, σ, is approximately 4.73 kg
Step-by-step explanation:
The weights of the six puppies are;
[tex]x_i[/tex] = 1, 2, 7, 7, 10, and 15
The number of puppies, n = 6
Therefore, we have;
The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7
The standard deviation, σ, is given as follows;
[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{n}}[/tex]
By substituting, we have;
[tex]\sigma =\sqrt{\dfrac{ \left (1-7 \right )^{2} + \left (2-7 \right )^{2} + \left (7-7 \right )^{2} + \left (7-7 \right )^{2} + \left (10-7 \right )^{2} + \left (15-7 \right )^{2} }{6}}[/tex]
Simplifying gives;
[tex]\sigma =\sqrt{\dfrac{ \left (-6 \right )^{2} + \left (-5 \right )^{2} + \left (0 \right )^{2} + \left (0 \right )^{2} + \left (3 \right )^{2} + \left (8 \right )^{2} }{6}} =\sqrt{\dfrac{ 36 + 25 + 0 +0+ 9 + 64 }{6}}[/tex]
[tex]\sigma =\sqrt{\dfrac{ 134 }{6}} = \sqrt{\dfrac{67}{3} } \approx 4.72582[/tex]
The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.

Answer:
2x +6
Step-by-step explanation:
if f(x)=mx+b what are the values of m and b
The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.
example 1
y = mx + b
m = slope b = y-intercept
y = 3x - 1
m = 3 and b = -1
example 2
y = b + mx
b = y-intercept m = slope
y = 5 - 1/2x
m =- 1/2 and b = 5

The quantity is 25/8.
Given in words to evaluate the expression, 2 squared times 2 to the power of negative 5 and over 5 to the power of negative two.
Square of a number denotes a number to the power of 2.
The expression is : [tex]\frac{2^2\times2^{-5}}{5^{-2}}[/tex]
We have to use the law of exponents here:
[tex]a^m \times a^n = a^{m+n}[/tex]
and
[tex]\frac{a^m}{a^n} = a^{m-n}[/tex]
In the above cases, the bases should be same for the two numbers.
So [tex]2^2 \times 2^{-5} = 2^{-3}[/tex]
Also, negative exponents like [tex]a^{-m} = \frac{1}{a^m}[/tex].
Therefore, [tex]\frac{2^{-3}}{5^{-2}} = \frac{5^2}{2^3} =\bold{ \frac{25}{8} }[/tex]

calcaulate the reliability of the system if all components function properly with probability 0.95. [hint: a,b and c,d are not in sequel. start with parallel components!]
The reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and 0.80 is 0.99. The answer is option b.
What is reliability?The probability that a specific object will carry out its intended function for a specific amount of time under a specific set of circumstances without experiencing any failures is known as reliability.
The reliability definition is based on four criteria: function, fulfillment likelihood, duration, and environment. Maintainability and reliability are related because when a machine or product malfunctions, there may be a way to get it back into working order.
When we use the phrase "talking reliability-smart," we mean that any of the aspects that shape the device in parallel can be considered. This does not necessarily imply that they are physically parallel (in all circumstances), as parallel capacitors have a certain behavior in the circuit and may malfunction if one of them fails.
Parallel forms reliability is a measure of reliability obtained by giving the same set of people different versions of an assessment tool (each version must contain items that probe the same construct, talent, knowledge base, etc.
The complete question is given below:-
What is the reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and 0.80?
