If p = 2 3 , point b has a weight of 2, and point c has a weight of 4, find the weight of point a.
A fixed point Weight is the ideal weight for our bodies in order to function optimally and feel their best.
What are weighted points?"The set point is established over time," Harrison explains. "It's a complicated thing, but it appears to be your body's attempt to regulate itself, which results in a certain weight."
Even if set point theory is correct, it is possible to lose weight and keep it off. Avoiding fad diets and gradually losing weight may change your set point. It may allow your body to adjust to your new eating habits. You may be more successful if you seek the assistance of a therapist or a dietitian.
A fixed point Weight is the ideal weight for our bodies in order to function optimally and feel their best. It is the weight that our bodies can easily maintain—no micromanaging, counting calories, weighing food, and so on.

11. Pi (π) is the quotient of the circumference (C) and the diameter of a circle.
Type equation here.
The circle is a plane figure whose circumference is given by the formulae [tex]2\pi r[/tex]. Where r is the radius of the circle.
The area of the circle is given by the formulae [tex]\pi r^{2}[/tex] where again r is the radius of the circle and pie is the common factor in both the formulae
We also need to know that the radius of the circle is the half of the diameter of the circle and the diameter is twice the radius
From which we can derive the relation; d=2r where d is the diameter of the circle.
So, the formulae now in terms of diameter becomes [tex]\pi d[/tex] for circumference and [tex]\frac{\pi d^{2} }{4}[/tex] for area of the circle.

The number of rabbits on a farm at the end of month n is Pn The number of rabbits at the end of the next month is given by Pn+1 = 1.2P - 50 At the end of March there are 200 rabbits on the farm. (a) Work out how many rabbits there will be on the farm at the end of June. (b) Considering your results in part (a), suggest what will happen to the number of rabbits on the farm after a long time.
We need to know how to solve the equations by substituting values for this problem. (a)The number of rabbits on the farm at the end of June is 164 and (b) after a long time the number of rabbits on the farm will become zero.
In the given question we know that the number of rabbits on a farm at the end of month n is [tex]P_{n}[/tex] and that the number of rabbits at the end of the next month is [tex]P_{n+1} =1.2P_{n} -50[/tex]. We know that the number of rabbits at the end of March is 200, so we can have [tex]P_{1}[/tex]=200, we need to find the number of rabbits at the end of June, which will be [tex]P_{4}[/tex], we can form an equation from here
[tex]P_{4} =1.2P_{3} -50[/tex]
Since we don't know what [tex]P_{3}[/tex] is we can replace it by [tex]P_{2}[/tex] and then replace that by [tex]P_{1}[/tex].
[tex]P_{4} =1.2P_{3} -50\\P_{4} =1.2(1.2P_{2} -50)-50\\P_{4} =1.2(1.2(1.2P_{1} -50)-50)-50 = 1.2(1.44P_{1} -60-50)-50=1.728P_{1} -72-60-50=1.728P_{1} -182[/tex]
We know that [tex]P_{1} =200[/tex]
So, [tex]P_{4}[/tex]=1.728x200-182=345.6-182≈164
Therefore the number of rabbits at the end of June is 164 and after a long time the number of rabbits on the farm might become zero since the number of rabbits is decreasing with every month.

Answer:
∠ A = 42° , ∠ G = 85°
Step-by-step explanation:
the measure of an inscribed angle is half the measure of its intercepted arc.
(3)
∠ A is an inscribed angle , so
∠ A = [tex]\frac{1}{2}[/tex] BC = [tex]\frac{1}{2}[/tex] × 84° = 42°
(4)
∠ G is an inscribed angle but we require arc DF
the sum of the arcs in a circle = 360°
FG + GD + FD = 360°
70° + 120° + FD = 360°
190° + FD = 360° ( subtract 190° from both sides )
FD = 170°
Then
∠ G = [tex]\frac{1}{2}[/tex] DF = [tex]\frac{1}{2}[/tex] × 170° = 85°

Given last periods forecast of 65, and last periods demand of 62, what is the simple exponential smoothing forecast with an alpha of. 4 for the next period?.
The exponential smoothing forecast for next period is 63.2.
What is exponential smoothing?A time series forecasting technique called exponential smoothing can be expanded to support data with a systematic trend or seasonal component.
Now,
Given:
Last period forecast = 65Last period demand = 62α = 0.4To find: Simple exponential smoothing forecast with α = 0.4 for next period.
Finding:
Now, by the concept of exponential smoothing, forecast for next period will be given by:
Ft + 1 = α Dt + (1 - α)F,
where,
Ft+1 = the next forecast,
α = weighing factor,
Dt = actual value for this period,
F = forecast value for the current period,
Substituting the values in the above expression:
=> Ft + 1 = 0.4 (65) + (1 - 0.4) 62
=> Ft + 1 = 26 + 37.2

You have compared the obtained value with the critical value. what do you do next?
The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.
Critical value is a cut-off value that is used to mark the start of a region where the test statistic, obtained in hypothesis testing, is unlikely to fall in. In hypothesis testing, the critical value is compared with the obtained test statistic to determine whether the null hypothesis has to be rejected or not.
So, when we compared the obtained value with the critical value then after that Reject the null hypothesis if the obtained value is more extreme than the critical value.
and, If the value of the test statistic is less extreme than the critical value, then the null hypothesis cannot be rejected.

Find the solution to the system: -5/7-11/7x=-y and 7+5x=2y
The solution to the system of equation is x = 1 / 5 and y = 4
How to solve system of equation?The system of equation can be solved as follows:
- 5 / 7 - 11 / 7 x = - y
7 + 5x = 2y
let's rearrange the equations
Therefore,
- 11 / 7 x + y = 5 / 7
5x - 2y = -7
Let's multiply equation(i) by 7 to eliminate the fractions
Hence,
-11x + 7y = 5
5x - 2y = -7
Therefore, using substitution method
5x = -7 + 2y
x = -7 / 5 + 2 / 5 y
Hence,
-11(-7 / 5 + 2 / 5 y) + 7y = 5
77 / 5 - 22 / 5 y + 7y = 5
- 22 / 5 y + 7y = 5 - 77 / 5
-22y + 35y / 5 = 25 - 77 / 5
13y / 5 = -52 / 5
cross multiply
65y = -260
y = -260 / 65
y = 4
Hence,
5x - 2(4) = -7
5x - 8 = -7
5x = -7 + 8
x = 1 / 5
Therefore, the solution to the system of equation is x = 1 / 5 and y = 4
