Answer:
p(s) = 0,33
Step-by-step explanation:
n = 450
p₀ = 150/450 p₀ = 0,33 then q₀ = 0,67
n*p₀ = 0,33*450 = 150
n*q₀ = 0,67*450 = 301
n*p₀ and n*q₀ more than 10, we can approximate the binomial to a Normal Distribution Distribution
a) p - p₀ = z(c) * √ (p₀q₀)/n
z(c) = ??
CI 95 % then α = 5 % α = 0,05 α/2 = 0,025
z(c) = 1,96
p = p₀ ± z(c) * √ (p₀q₀)/n
p = 0,33 ± 1,96 * 0,022
p = ( 0,33 - 0,04 ; 0,33 + 0,04
p = ( 0,29 ; 0,37 )
The value of the center of the confidence Interval is 0,33
p(s) = 0,33

Faliha runs around a square field of side 70m, while Rameen runs around a rectangular field with length 90m and breadth 60m. Who covers more distance by how much?
[tex]\huge\sf\green{Answer :- }[/tex]
Given :- Side of the square field = 70mLength of the rectangular field = 90mBreadth of the rectangular field = 60mTo Find :-Perimeter of the square fieldPerimeter of the rectangular fieldSolution :-Perimeter of the square = 4 × side
By substituting values,
⇒ 4 × 70m
➥ 280m
Hence, Faliha runs 280m around a Square fieldPerimeter of the rectangle = 2( length + Breadth)
By substituting values,
⇒ 2( 90m + 60m )
⇒ 2( 150m)
➥ 300m
Hence, Rameen runs 300m around a rectangular fieldBy comparing perimeters, Rameen runs more than Faliha
Distance runs more by rameen = Distance covered by rameen - distance covered by faliha
By substituting values,
⇒ 300m - 280m
➠ 20m
Hence, Rameen runs more around a rectangular field by 20m[tex]\huge\sf\fcolorbox{red}{pink}{ItzDevilGirl}[/tex]

Select Yes or No to indicate whether each value of x is a solution to the given equation.
31=x+1
Answer:
Yes for:
x = 30
Step-by-step explanation:
Since 31 = x+1
Simplifying, 1 is deducted from 31 to get 30
This gives the two sides of the equation as 30 = x
Therefore, x = 30
This is a simple equation. It can easily calculate the value of x given the value on the other side of the equation. Therefore, x is a dependent variable in this system of equation. And just like every system of equation, the simple equation problem requires that the two sides of the equation are always kept in balance or equilibrium.
A baker has 12 pounds of almonds. She puts them in a bag so that each bag has the same weight. Clare and Tyler drew diagrams and wrote equations to show how they were thinking about 12 ÷ 6. How do you think Clare and Tyler thought about 12 divided 6? Explain what each diagram and each part of each equation (especially the missing number) of might mean in the context of the bags of almonds.
Answer:
12 is how many pound of almonds there are. 6 is how many bags. 2 is how many almons there are in one bag for Tyler. For Clare is 12 almonds when there are 2 bags and there are 6 almonds in each bag.
Step-by-step explanation:
For Clare there is 12 almonds, there are 2 bags and there are 6 almonds in each bag.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
We are given that baker has 12 pounds of almonds.
Since Clare and Tyler drew diagrams and wrote equations to show how they were thinking about 12 ÷ 6.
12 is the pound of almonds there and 6 is the bags.
We conclude that 2 is how many almonds there are in one bag for Tyler.
For Clare is 12 almonds, when there are 2 bags and there are 6 almonds in each bag.

how to do 15 1/2 - 2 1/10 how to do it
First, you need to make the fractions have the same denominator:
15 1/2 ---> 15 + (1/2 x 5) = 15 5/10
2 1/10 ---> 2 1/10
Then you need to subtract them from each other:
15 5/10
- 2 1/10 (or) 15 5/10 - 2 1/10 = 13 4/10
13 4/10
This gets the answer: 13 4/10
Suppose that a recent poll of American households about pet ownership found that for households with pets, 45% owned a dog, 34% owned a cat, and 10% owned a bird. Suppose that three households are selected randomly and with replacement and the ownership is mutually exclusive. What is the probability that all three randomly selected households own a dog
Answer: 0.091125
Step-by-step explanation:
Given : P(dog) = 0.45
If 3 households are selected randomly and with replacement and the ownership is mutually exclusive.
Then , probability that all three randomly selected households own a dog = [tex](0.45)^3=0.091125[/tex]

To determine the average price of hotel rooms in Atlanta, a sample of 49 hotels was selected and the sample mean price of hotel rooms, top enclose y is $120. The population standard deviation was found to be $16. What is the standard error of top enclose y
Answer:
Standard error of top enclose y = 2.29
Step-by-step explanation:
The formula for Standard error = σ/√n
σ is the population standard deviation = $16
n is random number of samples = 49 hotels
Hence,
Standard error = 16/√49
= 16/7
= 2.2857142857
Approximately = 2.29

Outside a home, there is a 10-key keypad with the letters A, B, C, D, E, F, G, H, I, and J that can be used to open the garage if the correct ten-letter code is entered. Each key may only be used once. How many codes are possible? The number of possible codes is:_____
Answer:
3,628,800 (aka "10!")
Step-by-step explanation:
The first letter in the code can be 10 possible letters.
Since every letter can only be used once, the second letter can only be 9 possible letters.
E.G.: If the first letter is A, the second letter is B-J.
The third letter would be 8 possible letters, than the fourth would be 7, etc.
In math form, figuring out the possible combinations would be written out as so:
10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
An easier way to write this out would be using "10!", which stands for "10 Factorial"
The result of the above equals 3,628,800.

Write an expression to represent Donovan's total score of one of his words contains six letters
Question:
Donovan is playing a word game with letter tiles. Players earn 10 points for every word they make with the tiles., plus 5 extra points if a word has 6 or more letters. At the end of the game, 3 points are taken away for each tile not used. Write an expression to represent Donovan's total score if one of his words contains 6 letters.
Answer:
[tex]Total = 10w + 5 - 3t[/tex]
Step-by-step explanation:
Given
[tex]Points = 10[/tex]
[tex]Extra\ Point = 5[/tex]
[tex]Taken\ Away = 3[/tex]
Required
Represent as an expression
Represent the words with w
So, the total points for w words is:
[tex]w\ Points = 10*w[/tex]
[tex]w\ Points = 10w[/tex]
Also, he will earn the extra point because his 1 word contain 6 letters.
So, the new point is:
[tex]New\ Point = w\ Point + 1 * Extra\ Point[/tex]
[tex]New\ Point = 10w + 1 * 5[/tex]
[tex]New\ Point = 10w + 5[/tex]
Lastly, represent the number of tiles remaining with t.
3 points are taken away for 1 tiles left
3*t points will be taken away for t tiles left
So, Donovan total points is:
[tex]Total = 10w + 5 - 3 * t[/tex]
We subtracted because the points are taken away
[tex]Total = 10w + 5 - 3t[/tex]
solve the question below
Answer:
The answer is below
Step-by-step explanation:
1) A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.
Given that triangle ABC is right angled and AC = 25 cm = hypotenuse and BC = 15 cm. Using Pythagoras:
AC² = BC² + AB²
25² = AB² + 15²
AB² = 25² - 15²
AB² = 400
AB = √400
AB = 20 cm
Using sine rule:
[tex]\frac{sin(B)}{AC}=\frac{sin(A)}{BC}=\frac{sin(C)}{AB}\\\\But\ \angle B= 90^o(right\ angle)\ hence:\\\\ \frac{sin(B)}{AC}=\frac{sin(A)}{BC}\\\\\frac{sin(90)}{25}=\frac{sin(A)}{15}\\\\sin(A)=\frac{sin(90)}{25}*15\\\\sin(A)=0.6\\\\A=sin^{-1}(0.6)\\\\A=36.87^o[/tex]
2)
Using Pythagoras:
hypotenuse² = 8² + 6²
hypotenuse² = 100
hypotenuse = √100
hypotenuse = 10
Using sine rule:
[tex]\frac{sin(x)}{8}=\frac{sin(90)}{10}\\\\sin(x)=\frac{sin(90)}{10}*8\\\\sin(x)=0.8\\\\x=sin^{-1}(0.8)\\\\x=53.13 ^o[/tex]
