You measure 47 backpacks' weights, and find they have a mean weight of 79 ounces. Assume the population standard deviation is 13.1 ounces. Based on this, what is the maximal margin of error associated with a 90% confidence interval for the true population mean backpack weight.
Give your answer as a decimal, to two places
Answers
Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :
3.1433174885
= 3.14

column chart ( (Days Frequency)(1-3 1)(4-6 22)(7-9 14)(10-12 2)(13-15 17) )
Answers
The mean number of unused vacation days is 8.64.
What is the mean number?Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number.
To find the mean of the unused vacation days, find the midpoint of the upper and lower boundary and then multiply by its respective frequency and divide the sum by the sum of frequency.
Days Frequency Mid point (mid point x frequency)
1 - 3 1 (1 + 3) / 2 = 2 (2 x 1) = 2
4 - 6 22 (4 + 6) / 2 = 5 (5 x 22) = 110
7 - 9 14 (7 + 9) / 2 = 8 (8 x 14) = 112
10 - 12 2 (10 + 12) / 2 = 11 (11 x 2) = 22
13 - 15 17 (13 + 15) / 2 = 14 (14 x 17) = 238

Given the annual deposit amount and annual interest rate, future value of the annuity in the given period of time is $283,208.03.
What is the total amount accrued in the given period of time?Annuity is simply a mechanism to create substantial amount in future by making relatively very small periodic payments up until maturity.
It is expressed mathematically as;
F = P × (( (1+r)^(nt) - 1 )/r)
Given the data in the question;
Annual deposit amount P = $2,500Annual interest rate r = 8% = 8/100 = 0.08Compounded annually = Ones in a year = 1Time t = 30 yearsFuture value = ?Plug the given values into the equation above and solve for A.
F = P × (( (1+r)^(nt) - 1 )/r )
F = 2500 × ( ((1 + 0.08 )^(1×30) - 1 ) / 0.08 )
F = 2500 × (( (1.08 )³⁰ - 1 ) / 0.08 )
F = 2500 × ( 10.06265688 - 1)/0.08 )
F = 2500 × ( 9.06265688/0.08 )
F = 2500 × 113.28321111
F = $283,208.03

find the domain and function of y=6+9x/6-|x-1|
Thank you so soooo much for the help!!
Answers
======================================================
Explanation:
Rule: We cannot divide by zero.
Because of that rule, we'll set the denominator equal to zero and solve for x. This way we can determine the x value(s) that are to be excluded from the domain.
6 - |x-1| = 0
|x-1| = 6
x-1 = 6 or x-1 = -6
x = 6+1 or x = -6+1
x = 7 or x = -5
Those x values are to be excluded from the domain, since they make the denominator zero.
Imagine a number line in which we poked open holes at -5 and 7
The portion to the left of -5 is x < -5The portion between -5 and 7 is -5 < x < 7The portion to the right of 7 is x > 7Combining everything gets us x < -5; -5 < x < 7; x > 7

The length of the side a in the given right-angled triangle is 8 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.
The given right-angled triangle has a base of 15 units and a hypotenuse of 17 units.
Therefore,
17² = 15² + a².
a² = 17² - 15².
a = [tex]\sqrt{289 - 225}[/tex].
a = [tex]\sqrt{64}[/tex].

Answers
The cost of hot dogs are 1.25 and the cost of hamburgers are 1.50.
How to calculate the cost?Let x=hot dogs a/
Let y = hamburgers
x + 7y = 11.75
x + y = 2.75
Subtract the second equation from the first.
x + 7y = 11.75
-(x + y = 2.75)
------------------------
6y = 9.50
divide by 6
y = 1.50
Substitute the y value in the simplest equation to solve for x
x + y = 2.75
x + 1.50= 2.75
-1.50 -1.50
x = 1.25

a ship sails 677km (to 3s.f) on a high tide on the sea 8hrs to the nearest hour. calculate its speed in km/hr correct to 3s.f
Answers
The speed of the ship is the distance travelled divided the time taken to reach the shore here the answer will be 677/8 = 84.625km/hr.
The given sum is basically a sum of time distance and speed . here we are provided with the distance and the time taken for the ship and we are asked to calculate the speed of the ship. We know the formula that Distance = speed*time so from this formula we can calculate the speed of the ship that is : speed = distance/time taken ,
we are provided with the distance = 677km and the time taken to cover that distance is 8hrs .As we have the necessary information we can now calculate the speed of the ship with which it covered the distance of 677km in a time span of 8 hours.
according to the question :
distance = 677 km
time taken = 8hour
∴ speed=distance/time
= 677/8 = 84.625km/hr

4) The fishing fleet left Manilow Bay when the water level reached

and ½ feet per hour for the next 6 hours. The depth of the water was
measured every hour on the hour. At what time may the fleet leave?
Answers
The time the fleet may leave the Manilow Bay given the rate at which the depth rises is 9am.
What time may the fleet leave?The fishing fleet would leave when the water level reaches 32. At 5 am, the water level is 27 feet. The water level needs to rise 6 more feet (32 - 27) before the fleet can leave.
In order to determine the time, divide 6 feet by the rate at which the tide rises. Division is the mathematical operation that is used to determine the quotient of two or more numbers.
Hours when the tide would rise 6 feet = 6 ÷ 1 1/2

THE DIFFERENCE OF
TWO NUMBERS IS 10,WHILE THEIR PRODUCT IS 39.FIND THESE NUMBERS
Answers
The numbers are 13 and 3.
Let the numbers be x and y. Equation representing difference of these numbers-
x - y = 10 : equation 1
Equation representing product of these numbers- x × y = 39 : equation 2
Rewriting the equation 2 in terms of y
y = 39/x : equation 3
Keeping the value of y from equation 3 in equation 1
x - 39/x = 10
Multiplying the equation by x
x² - 39 = 10x
Rearranging the equation
x² - 10x - 39 = 0
Factorising the equation
x² - 13x + 3x - 39 = 0
x(x - 13) +3 (x - 13) = 0
(x + 3) (x - 13) = 0
Value of x = 13 and -3
Taking positive value of x
Keeping value of x in equation 3
x = 13
y = 39/13
y = 3

John Beale of Stanford, California, recorded the speeds of cars driving past his house, where the speed limit read 20 mph. The mean of 100 readings was 23.84 mph, with a standard deviation of 3.56 mph. (He actually recorded every car for a two-month period. These are 100 representative readings.) a. How many standard deviations from the mean would a car going under the speed limit be? b. Which would be more unusual, a car traveling 34 mph or one going 10 mph?
Answers
How many standard deviations from the mean would a car going under the speed limit be -1.0787
Which would be more unusual: a car traveling 10 mph
Given data:
At speed limit of 20 mph mean of 100 readings was 23.84 mph
and a standard deviation of 3.56 mph
The speed limit read 20 mph
How to find the standard deviations from the mean that the car going under the speed limitAssuming the car going under the speed limit of 20 mph be y
such that
20 = 23.84 + y * 356
356y = 20 - 23.84
y = ( 20 - 23.84 ) / 356
y = -1.0787
How to find which is more unusualA car traveling 34 mph: using y same as number of deviations from the mean
34 = 23.84 + 3.56y
y = ( 34 - 23.84 ) / 3.56
y = 2.8539
Meaning the car travelling at 34 mph is 2.8539 standard deviations above the mean
A car traveling 10 mph: using y same as number of deviations from the mean
10 = 23.84 + 3.56y
y = ( 10 - 23.84 ) / 3.56
y = -3.8876
Meaning the car travelling at 10 mph is 3.8876 standard deviations below the mean
From the the rule that 99.7% of the observations lie with in ±3 standard. The speed of 10 mph is outside these limits but 34 mph is within the limits. Hence we say that the car travelling 10 mph is more unusual
