Answer:
B.any collection of random variables in a sequence is taken and shifted ahead by htime periods, the joint probability distribution remains unchanged
Step-by-step explanation:
In most of the time series techniques , there is usually a common assumption that data are stationary. A stationary process can be regarded as one that has properties such as variance mean, variance as well as autocorrelation structure not changed over time. The properties is independent as regards the time the series is observed.
✓ Time series that has trends or seasonality cannot be regarded as stationary, because the value of the time series which exist in different times will be affected by the trend and seasonality.
✓A white noise series can be regarded as stationary because the time you observe it does not matter, it will always look much the same at all point in time.
✓ It should be noted that process is stationary if any collection of random variables in a sequence is taken and shifted ahead by htime periods, the joint probability distribution remains unchanged

Sodas cost $1.50 and a cup of coffee costs $1.25 at a football game. Sally
bought 8 drinks total for all of her friends and her total cost was $11.50. How
many of each drink did she buy?
Answer:
the answer 4
Step-by-step explanation:
4 of each because (1.25x4) + (1.50x4) = 11.50
Answer:
Sally bought 6 sodas and 2 cups of coffee.
Step-by-step explanation:
Variable x = number of sodas
Variable y = number of coffees
$1.50x + $1.25y = $11.50
x + y = 8 drinks
$1.50(6) + $1.25(2) = $11.50
$9.00 + $2.50 = $11.50
I simply plugged in numbers that totalled to 8 drinks until I reached $11.50 as the total.
For example:
$1.50(5) + $1.25(3) = $11.50
$7.50 + $3.75 = $11.50
$11.25 = $11.50
This is not correct as they do not equal so this cannot be the answer.

A teacher wants to choose a student at random. The teacher decides to choose the first person to walk through the classroom door at the start of the lesson.
a. Explain why this is not a good method.
2. Suggest a better method.
Answer:
The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.
The odds of the person who lives 20km away from the school being first are way lower than anyone else.
A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $ 100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below. Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance. Natasha uses the $25 off the repair cost coupon first. She then uses the %20% off the repair cost coupon on the remaining balance.

The diameter of a circle is 11 cm. Find its area to the nearest tenth.
Answer:
95.0
Step-by-step explanation:
Area of a circle
A = πr2
Radius is half the diameter = 11/2 = 5.5
A = π x 5.5 x 2
= 95.033177...
= 95.0
5+2x = -27/8
How explain
Answer:
x = -4 3/16.
Step-by-step explanation:
First, convert -27/8 to a mixed number. -3 3/8.
So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)
The equation turns into this: 2x = -8 3/8.
Now we can divide by 2 on both sides.
The equation becomes x = -4 3/16.
Hope this helps!
I need help on this math problem
Answer:
B, C, D
Step-by-step explanation:
7x + 1 + 105 = 180
7x = 74
x = 74/7
4y + 14 + 7y + 1 = 180
11y = 165
y = 15
m<A = 4y + 14 = 4(15) + 14 = 74°
m<B = 7x + 1 = 7(74/7) + 1 = 75°
m<C = 7y + 1 = 7(15) + 1 = 106°

Answer:
tan ∅ = 16/12
Step-by-step explanation:
Once again here are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Tangent
We are asked to find tan ∅
Looking at the trigonometric ratios we see that tan = opposite over adjacent
So we find the side length opposite of the indicated angle (∅) which would be 16 then we find the angle adjacent angle ( the side that is not the hypotenuse nor the opposite ) so the adjacent of angle ∅ is 12
so tan ∅ = opposite (16) over adjacent (12)
tan ∅ = 16/12

[tex]A=\pi 10^{2}[/tex]
[tex]A= 314.16m^{2}[/tex]
∠A and ∠B form linear pair. If m∠A =(6x-19)° and m∠B=(11x-22)°, find m∠B.
Answer: 121°
Step-by-step explanation:
The measure of angle B will be [tex]121^0[/tex] .
What is angle?Angle is formed by two rays lie in the plane that contains the rays.
We have,
[tex]m \angle A =(6x-19)^0[/tex]
Now,
Linear pair angles are those angles whose sum is [tex]180^0[/tex] .
i.e.
[tex]m \angle A + m \angle B=180^0[/tex]
So,
[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]
Now,
[tex]17x-41=180[/tex]
[tex]17x=221[/tex]
[tex]x=13[/tex]
So,
[tex]m\angle B=(11x-22)^0[/tex]
Putting value of x;
[tex]m\angle B=(11*13-22)^0[/tex]
[tex]m\angle B=(121)^0[/tex]
So, measure of angle B is [tex]121^0[/tex].
Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .

a.) 345 > 354
b.) 400 < 40
c.) 4,008 < 4,080
d.) 23,090 = 23,009
Answer:
I think C
so it's kind of a process of elimination you have to see the order of the numbers and what order each number is in so for A you can see that it's 345 is greater than 354 which is inspect cuz 354 is greater than 345 for B that's an obvious answer is is 400 is less than 40 which is obviously wrong because 400 is greater has two zeros and 40 only has one 0 for C it has 4008 is less than 4080which is actually correct if you look at the way that the numbers are written you could see that 80 is greater than 8 D it's obviously not correct because it says 20090 is equal to 23009 which is incorrect because 90 is greater than 9
