The weights of 9-ounce bags of a particular brand of potato chips can be modeled by a normal distribution with mean μ = 9.12
ounces and standard deviation = 0.05 ounce.
What bag weight is at the 84th percentile of the distribution?
Use the empirical rule and do not round.
ounces
Answers
It should be noted that the bag weight that is at the 84th percentile of the distribution is 9.17 ounce.
How to illustrate the information?It's important to vompute the z-score for 84th percentile then find the 84th percentile of the distribution for bag weight.
From the standard normal table, the indicated z score for the area of 0.8400 and indicative area 0.8400 is 0.99.
The z-score is 0.99.
The 84th percentile (P) of the distribution for bag weight will be:
= 9.12 + (0.09 × 0.05)
= 9.12 + 0.05
= 9.17.
Therefore, the 84th percentile of the distribution for bag weight will be 9.17.

nikki and kelly can create math problems for a particular course in 20 hours. alone, nikki can do write all of the problems 4 hours faster than kelly could if she were to work alone. how long would it take each person to write the problems if they worked alone?
Answers
Nikki alone can do work to write the problem in 43 hours, and Kelly can work in 39 hours.
What are work and time?
Work is the energy expended to complete a task or produce a deliverable. It takes a specific amount of time (T) to finish a particular task (W). The rate of work is the number of units of work completed per unit of time (R). Therefore, Work (W) = Rate (R) Time (T), and Work = Force Distance can be used to determine Work.The joule (J), sometimes known as the Newton meter (N m), is the SI unit for work. When an object is moved across a distance of 1 m with 1 N of force, one joule is equal to the amount of work that is accomplished.
Work and time are proportionate to one another. Because of this, more work can be done with more time, and vice versa.
Nikki can do the part of this problem in 1 hour = 1/x
And, Kelly can do the part of this work in 1 hour = 1/(x - 4)
So, Nikki and Kelly both can do this work in 1 hour = (1/x) + [1/(x - 4)] = 120
= 40x - 80
= x² - 4x
= x = 43, 2
Hence,
Nikki alone can do work to write the problem in 43 hours, and Kelly can work in 39 hours.

Where will the hour hand of clock stops if it starts from 7 and goes through 3right angles
Answers
The hour hand that goes through 3 right angles and starts from 7 will stop at 4.
We can assume that the numbers in a clock are positioned in a circle. The angle in a circle is 360⁰, while the numbers in a clock is 12.
Hence, from each clock number to its consecutive number, the hour hand must travel 30⁰ as shown in the attached picture.
A right angle is equal to 90⁰. This is equal to 3 ⨉ 30⁰. In other words, to travel 90⁰ means to travel 3 hours.
3 right angles = 3 ⨉ 90⁰
= 3 ⨉ 3 hours
= 9 hours.
Thus, the hour hand will go to:
7 + 9 = 16
16 is equal to number 4 in a clock number.
Conclusion: If the hour hand start from 7, it will stop at clock number 4.

a fire truck is called to a scene. three minutes later, a second truck is called. the first truck averages only 30 miles per hour, but the second averages 60 miles per hour. the truckcs travel a total of 12 miles and arrive at the same time.
Answers
The trucks arrive 10 minutes after the first call. The first and the second truck travel for 5 miles and 8 miles respectively.
In a time difference of 3 minutes, two fire trucks are called.
The average speed of the first truck is 30 miles per hour.
The average speed of the second truck is 60 miles per hour.
The trucks totally travel for 12 miles and arrive at the same time.
Let d be the number of miles the first truck drove.
Let t be the number of minutes it took the first truck to travel.
Now, Convert 30 miles per hour to a half mile per minute and 60 miles per hour to a mile per minute as we are measuring time in minutes.
For the first truck:
d = 0.5t
The second truck traveled 12 - d miles if the first truck traveled d miles. In the event where the first truck traveled for t minutes and was called 3 minutes later, the second vehicle would have gone for t - 3 minutes.
For the second truck:
12 - d = t - 3
Therefore,
12 - 0.5t = t - 3
15 = 1.5t
t = 15 / 1.5
t = 10 minutes
The trucks arrive after 10 minutes after the first call.
Then,
d = 0.5t = 0.5(10) = 5 miles
And 12 - d = 12 - 5 = 8 miles.
Hence, the first truck traveled for 5 miles and the second truck traveled for 8 miles.

What is Quadratic Formula?In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation.
Given a general quadratic equation of the form
ax^2 + bx + c = 0
with x representing an unknown, with a, b and c representing constants, and with a ≠ 0, the quadratic formula is:
[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]
and,
Now the given quadratic equation is,
x^2 - 2x = - 9
or, x^2 - 2x + 9 = 0
here, a = 1
b = -2
c = 9
Thus quadratic formula is given as,
[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]
[tex]{\displaystyle x={\frac {-(-2)\pm {\sqrt {(-2)^{2}-4*1*9}}}{2*1}}[/tex]

What is the solution set to the equation 2/7-m=4/m - 5-m/7-m
Answers
The equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m
How to determine the solution set to the equation?The equation is given as
2/(7 - m) = 4/(m - 5) - m/(7 -m)
Take the like terms of the above equation
So, we have
m/(7 -m) + 2/(7 - m) = 4/(m - 5)
Evaluate the like terms in the above equation
So, we have
(m + 2)/(7 -m) = 4/(m - 5)
Cross multiply the above equation
So, we have
m^2 + 2m - 5m - 10 = 28 - 4m
Evaluate the like terms
m^2 + m + 18 = 0
Using a graphing tool, we have no solution for m
Hence, the equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m
