Answer:
a) 0.5 = 50% of flanges exceed 1 millimeter.
b) A thickness of 0.96 millimeters is exceeded by 90% of the flanges
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.
This means that [tex]a = 0.95, b = 1.05[/tex]
(a) Determine the proportion of flanges that exceeds 1.00 millimeters.
[tex]P(X > 1) = \frac{1.05 - 1}{1.05 - 0.95} = \frac{0.05}{0.1} = 0.5[/tex]
0.5 = 50% of flanges exceed 1 millimeter.
(b) What thickness is exceeded by 90% of the flanges?
This is x for which:
[tex]P(X > x) = 0.9[/tex]
So
[tex]\frac{1.05 - x}{1.05 - 0.95} = 0.9[/tex]
[tex]1.05 - x = 0.9*0.1[/tex]
[tex]x = 1.05 - 0.9*0.1[/tex]
[tex]x = 0.96[/tex]
A thickness of 0.96 millimeters is exceeded by 90% of the flanges
find the greatest 5 digit number which exactly divide by 16, 56 and 120
five-digitsinceStep-by-step explanation:
Ummm.....I have never done this before but I THINK what your supposed to do is find the lcm of all the pairs you can get from those 3 numbers.
so lcm(16,56)=112
lcm(56,120)=840
lcm(16,120)=240
Now take any number from this and take the lcm of that
lcm(112,840)=1680
that is the number if you take the lcm of any of them so it is the lcm of them all but it is not a number. so 16,56, and 120 are divisible by 2 I just multiplied 1680 by 2 until I got the highest possible 5 digit number which was 53760
Hope that helps :)

Answer:
99120
Step-by-step explanation:
The LCM of 16, 56, 120 can be found from their factors:
16 = 2^4
56 = 2^3 · 7
120 = 2^3 · 3 · 5
So, the least common multiple is 2^4×3×5×7 = 1680.
10^5/1680 = 59 r 880
The largest 5-digit number divisible by 16, 56, and 120 is 59×1680 = 99120.

A car travels 6 mile in 2 hours what is the unit rate
A 3 miles/ hour
B 1 mile/3 hour
C 3 /1 mile
D6 miles/ 1 hour
Answer:
A
Step-by-step explanation:
This is a fraction equal to
6 miles ÷ 2 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
6 miles ÷ 2 2 hours ÷ 2= 3 miles1 hour= 3 miles hour = 3 miles per hour
Put the equation y =x^2-8x + 12 into the form y(x-h)^2+k
Answer: y =
Answer:
y = (x - 4)² - 4
Step-by-step explanation:
y = x² - 8x + 12
y = ( x² - 2(4)x + 4² ) - 4² + 12
y = (x - 4)² - 4

Determine whether the variation between the indicated quantities is direct or inverse.
The time required to defrost a frozen hamburger in a room and the temperature of the room.
Choose the correct answer below.
Inverse
Direct
Answer:
Inverse variation
Step-by-step explanation:
Required
What type of variation is described in the question
From the question, we understand that: the relationship is between time and temperature
The higher the time, the lower the temperature of the hamburger (to get freeze).
Hence, the relationship is an inverse variation.
Over 4 days, Krista deposited $45 into
her bank account, transferred $30 to a
friend, deposited $59, and withdrew
$18. What was the mean change per day
to Krista's account during that week?
Answer:
50
Step-by-step explanation:
45 - 30 = 15
15 + 59 = 74
74 - 18 = 56
The mean change per day to Krista's account during the week is $ 14
What is Average?
The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Given data ,
The total sum of money in Krista's account = $45 - $30 + $59 - $18
= $56
Total number of days = 4 days
Now ,
Mean change per day = Sum of money in Krista's account / Total number of days
Mean change per day = 56 / 4
= $ 14
Hence , The mean change per day to Krista's account during the week is $ 14

Answer:
C. 73 and 73
Step-by-step explanation:
An isosceles triangle has two angles that are the same, that narrows it down to C and D. The question states that there is only one 34° angle so it has to be C.
Answer:
C. 73° and 73°
Step-by-step explanation:
We know that the sum of interior angles in a triangle is equal to 180° and
Isosceles triangles has two angles with same measurement
it stated in the question that exactly one angle has measure of 34°
So the other two angles must be equal for the triangle to be isosceles
180 - 34 = 146 and this divided by 2
73° and 73° is the answer.

C.

Answer: Vertical angle proof
Step-by-step explanation: First off, this is really easy if you know how to do it. I think you should be able to figure it out. If you really are in collage. So Vertical angle proof, QPR is essentially (2x-30) but we need to find x. We know a triangle is 180 degrees and if it's a right angle then two angles add to 90.
So x+(2x+30)=90, 3x+30=90, 90-30=60, 3x=60, x=20. So there you have it. Now put x into the equation, 2(20)+30=70
