The diameters of bolts produced in a machine shop are normally distributed with a mean of 6.4 millimeters and a standard deviation of 0.06 millimeters. Find the two diameters that separate the top 5% and the bottom 5%. These diameters could serve as limits used to identify which bolts should be rejected. Round your answer to the nearest hundredth, if necessary.
Answer:
The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.
Step-by-step explanation:
We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.
Let us find the sample score that corresponds to z-score of bottom 4%.
From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.
Upon substituting these values in z-score formula we will get our sample scores (x) as:
Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.
Now let us find sample score corresponding to z-score of 1.75 as upper limit.
Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected
Answer:

whats the area of the triangle
Please its already overdue
Answer:
[tex]Area = 15in^2[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Determine the area
The attached shape is a triangle and the solution is:
[tex]Area = 0.5 * Base * Height[/tex]
So, we have:
[tex]Area = 0.5 * 10in * 3in[/tex]
[tex]Area = 15in^2[/tex]
Mitch throws a ball over A 20 foot fence to a baseball field. The height, H, of the ball at the time T seconds after it was the round can be modeled by the equation H(t)=16^2 + 30t+6
which statement is true?
Answer:
(a) At 1.5 seconds, the ball is 15ft high
Step-by-step explanation:
Given
[tex]Fence:= 20ft[/tex]
[tex]h(t) := -16t^2 + 30t + 6[/tex]
Required
Select the true statement
See attachment for options
Option (a): At 1.5 seconds, the ball is 15ft high
This implies that:
[tex]t = 1.5[/tex]
Substitute [tex]t = 1.5[/tex] in [tex]h(t) := -16t^2 + 30t + 6[/tex]
[tex]h(1.5) = -16 * 1.5^2 + 30 * 1.5 + 6[/tex]
[tex]h(1.5) = -16 * 2.25 + 45 + 6[/tex]
[tex]h(1.5) = -36 + 45 + 6[/tex]
[tex]h(1.5) = 15[/tex]
This statement is true.
Because: [tex]h(1.5) = 15[/tex] means that:
At 1.5 seconds, the ball is 15ft high
Other options will not be checked because only one option can be correct

A shopkeeper paid $90 for 90 apples. He sold half of them for $3 each and the rest at $1 each.
Answer:
either $180 or $90?
Step-by-step explanation:
first i think you divide 90 by 2, which gives you 45. multiply 45 by 3, which is 135, then multiply 45 by 1, which is just 45. add those together and you get 180. i'm not too sure what you're looking for in the question, but if you're looking for the difference between what he bought them for, it'd be $90. if youre looking for how much he got from those apples, it's $180. hope that helps :)

the number of days, d, that it will take to run a marketing campaign is given by d = 192/n where n is the number of people needed each day. alex’s company will take 32 days to run the campaign. shay’s company will take 24 days to run the campaign. shays company will have to use more people each day than alex’s company. how many more?
Answer:
2 more people each day.
Step-by-step explanation:
We are given the following relation:
[tex]d = \frac{192}{n}[/tex]
In which d is the number of days that will take to run a marketing campaign with n people.
Alex’s company will take 32 days to run the campaign.
So the number of people in his campaign is given by:
[tex]32 = \frac{192}{n}[/tex]
[tex]32n = 192[/tex]
[tex]n = \frac{192}{32}[/tex]
[tex]n = 6[/tex]
Shay’s company will take 24 days to run the campaign.
So the number of people in her campaign is given by:
[tex]24 = \frac{192}{n}[/tex]
[tex]24n = 192[/tex]
[tex]n = \frac{192}{24}[/tex]
[tex]n = 8[/tex]
Shays company will have to use more people each day than alex’s company. how many more?

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that John and his dad decide to order a pizza to eat while they are watching a World Cup Soccer game. John eats 2/5 of the pizza, and his dad eats 3/7 of the pizza.
The amount of pizza left will be calculated as below:-
Pizza left = 1 - ( 2/5) - (3/7)
Pizza left = ( 35 - 14 - 15 ) / 35
Pizza left = 6 / 35
Therefore, the amount of pizza left will be 6 / 35.

Maria decides to increase her homework time of 8 hours per week by 15% Calculate her new homework time. Give your answer in hours and minutes
Answer:
Maria's homework time is now 9 hours 12 minutes.
Step-by-step explanation:
Since Maria decides to increase her homework time by 15%.
Then,
15% of 8 hours = [tex]\frac{15}{100}[/tex] x 8 hours
= 0.15 x 8 hours
= 1.2 hours
(Note that: 1.2 hours = 1 hour 12 minutes)
15% of 8 hours = 1 hour 12 minutes
her new homework time = 8 hours + 1 hour 12 minutes
= 9 hours 12 minutes
Maria's homework time is now 9 hours 12 minutes.
Sophie earns $12.80 per hour babysitting. She has to repay a loan to her parents in the
amount of $100. After repaying the loan, she wants to have at least enough money to buy
herself a pair of sneakers costing $130.40. Write an inequality modeling the number of hours,
X, Sophie needs to work to have enough money to buy the sneakers.
Answer:
Sophie has to work 18 hours to buy the sneakers.
Step-by-step explanation:
Since Sophie earns $ 12.80 per hour babysitting, and she has to repay a loan to her parents in the amount of $ 100, and after repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $ 130.40, for write an inequality modeling the number of hours, X, Sophie needs to work to have enough money to buy the sneakers, the following mathematical reasoning must be carried out:
12.80X = 100 + 130.40
12.80X = 230.4
X = 230.4 / 12.8
X = 18
So Sophie has to work 18 hours to buy the sneakers.
0.2) Sharad bought one quintal of onions for Rs 2000. Later he
sold them all at the rate of Rs 18 per kg. Did he make a profit
or incur a loss? How much was it?
Answer: Loss, 200 Rs
Step-by-step explanation:
Given
Sharad bought a quintal of onion i.e. [tex]1000\ kg[/tex] for [tex]Rs.\ 2000[/tex]
So, the cost price of onion is
[tex]\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}[/tex]
He sells it at [tex]18\ \text{Rs. per kg}[/tex]
Here, the Selling price is less than the cost price
So, he incurs a loss of [tex]2\ \text{Rs per kg}[/tex]
For a quintal it is
[tex]\Rightarrow 2\times 100=200\ \text{Rs}[/tex]
[tex]\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%[/tex]

Answer:
(x,y) = (4,3), (20,35)

Answer:
Distance between cities Y and Z = 26 miles
Step-by-step explanation:
From the picture attached,
Length of XY = 10 mi
Length of XZ = 24 mi
By applying Pythagoras theorem in the given right triangle XYZ,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
YZ² = XY² + XZ²
= 10² + 24²
= 100 + 576

Answer: 49
Step-by-step explanation:
The missing constant term in the perfect square is 49.
x^2 + 14x + 49
We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.
