The confidence interval of p±E is 0.555±0.444
Definition of confidence interval-A Confidence Interval is a region constructed using sampled data, of fixed size, from a population (sample space) following a certain probability distribution. The interval is constructed to contain a chosen population statistic with prescribed probability.
A confidence interval, in statistics, refers to the probability that a population parameter will fall between a set of values for a certain proportion of times. Analysts often use confidence intervals than contain either 95% or 99% of expected observations. Thus, if a point estimate is generated from a statistical model of 10.00 with a 95% confidence interval of 9.50 - 10.50, it can be inferred that there is a 95% probability that the true value falls within that range.
Given:-0.111<p<0.999=Confidence interval. we have to express it in the form p±E.
Explanation:-The midpoint of the interval is p.
p=[tex]\frac{0.111+0.999}{2}[/tex]=0.555
Next the error term E is the distance from p to the end of the interval.
E=0.999-0.555=0.444
So, finally we get the answer as p±E=0.555±0.444
The final answer is p±E=0.555±0.444

Una persona ahorra todos los meses el mismo monto de dinero durante 1 año. Si luego de este tiempo reunió $243.000 ¿Cuánto dinero guardo cada mes?
Answer:
Ahorro por mes= $20.250
Step-by-step explanation:
Dada la siguiente información:
Ahorro total= $243.000
Número de meses= 12
Voy a suponer que empeza a ahorrar desde los cero $.
Debemos usar la siguiente formula:
Ahorro por mes= ahorro total / número de meses
Ahorro por mes= 243.000 / 12
Ahorro por mes= $20.250
Out of the 125 children at summer camp, 45 signed up for swimming and 38 signed up for arts and crafts. Twelve students who signed up for swimming also signed up for arts and crafts. If a child is randomly selected, what is the probability that they are signed up for swimming, if it is known that they did not sign up for arts and crafts? Please help!
Answer:33/125
Step-by-step explanation:
First, you subtract 12 from 45, because there were 45 who signed up for swimming and 12 of them also signed up for arts and crafts. So, there are 33 children, out of the 125, who only signed up for swimming. Which means there is a 33/125 chance that a child who only signed up for swimming is randomly selected.

Answer:
(a) ∠KHG = 120°
(b) (i) KG = 15.625 km
(b) (ii) bearing of G from K = 240°
Step-by-step explanation:
(a) 360° - 290° = 70°
∠KHG = 70° + 50° = 120°
(b) (i) ∠KGH = 26°
∠GKH = 34°
KG = 7.875 + 7.75 = 15.625 km
(b)(ii) Bearing from G from K = 110° + 130° = 240°

A company buys a digital scanner for $12,000.
The value of the scanner is $12,000 (1 - n/5 ) after years.
The
company has budgeted to replace the scanner when the trade-in value is $,400.
After how many years should the
company plan to replace the machine in order to receive this trade-in value?
Answer:
it will be n=4
Step-by-step explanation:
12,000 1-n/5 =2,400n
12000-12000=2,400
2,400-12000=-9600
-2400 n=4
You have to write a equation
Answer:
y = 3 sin 4x
Step-by-step explanation:
For y = a sin bx,
a is the amplitude which is the crest of the graph. In this case a = 3 from the given graph.
Now, b is associated with the period where; b = 2π/period
From the graph the period which is the time between where the graph crosses the x-axis = π/2
Thus; b = 2π/(π/2)
b = 4
Thus,equation is; y = 3 sin 4x

Answer:
(D) or 703.4^2 is the answer here.
Step-by-step explanation:
Well I would imagine this.
Imagine a cylinder right and its liek a soda can. If you cut the middle straight down (which is the height) and you pull out the whole sheet and flatten it, you get a rectangle. You have the height but no width. The width can be found be finding the Circumfrnce of the circle or the perimeter of the circle on top.
Circumfrence formula is C=dπ or in this case the radius is 7, double the radius which would be 14 and the diameter, multiply that by π, you’d Get 43.98229 smth.
Now you have the surface for that rectangle or the surface recall for the whole cylinder except for the top and bottom, you just gotta find the top and double it!.
The area of a circle is a=πr^2
Raidus in. This case is 7, 7^2=49. 49π double it (top and bottom) is 307 smth Yu add those two up and you’d get 703.4 smth so the answer is (D).
I need this answer as soon as possible will give brain thing
Answer: X=5 so whats 3 + 5? easy, 8. so now you know the bottom is eight and since it's a rectangle the top is also 8. And the left side is 15 so we know the right side is also 15. To find the perimeter you add all the sides of which in this case it would be 8 + 8 + 15 + 15. or (8 times 2) + (15 times 2). = 46 the answer is 46

Ms reynolds has 5 pounds of clay for her art club. If she divides the clay into 1 third pound pieces, how many pieces will she have?
Answer:
15
Step-by-step explanation:
Total quantity of clay = 5 pound
Now, Reynolds divides the clay into 1 third pound pieces.
this means each piece of clay weighs = 1/3 pounds
Therefore, number of pieces of clay = Total weight of clay/ weight of each piece
= 5/(1/3) = 15
In triangle ABC, where triangle B is the right angle, side AB has a length of 6 cm and side BC has a length of 10 cm. What is the length of side AC? A. 4 cm B. 6 cm c. 11.66 cm D. 8 cm
Answer:
11.66cm (c)
Step-by-step explanation:
Apply the phuthagorean theorem
Side opposite to the right angle in triangle is AC
AC²=ab²+bc²=10²+6²=100+36=136
We need AC so take the square root of 136 which is 11.66 as the answer

The designer wants to plant new flowers around the pond. How many feet of flowers would she need to plant in this new design? Round to the nearest hundredth. Show your work.
Answer: 1,257.14 ft
Step-by-step explanation:
The question is missing the vital detail of the diameter or radius of this circular pond which I found to be 400 feet.
The plants are to be planted around the pond which means that they are to be planted around the circumference of the pond.
The number of feet of flowers to be planted is therefore the circumference.
Circumference = π * diameter
= 22/7 * 400
= 1,257.14 ft

Because 30+135+45 add up to 210 then if you add 30, or 45 degrees it will be more than 180 degrees. If you subtract -15 from 210 you will get 195 which is still not right. So the best answer is none of the above
