WHAT PROPERTY IS 12.2+18.6+-4.3+(18.6)
Answer:
it has to be 45.1.
Step-by-step explanation:
The reason why its 45.1 is because I added the equation all together including the negative number. I out that one in parentheses right next to the plus sign of 18.6. then added the last 2 numbers. and get 45.1. I'm not really good with stop by step explanations to be honest.

Find the difference. Enter your answer in the box below as a fraction, using
the slash mark ( 1 ) for the fraction bar.
Answer:
2/17
Step-by-step explanation:
Given, [tex] \frac{16}{17} - \frac{14}{17} [/tex], to find the difference, first look for the common denominator of both fractions.
Common denominator of both fractions is 17.
Divide the common denominator by the denominator of each fraction, then multiply the result by its numerator and solve as follows:
[tex] \frac{1(16) - 1(14)}{17} [/tex]
[tex] \frac{16 - 14}{17} [/tex]
[tex] \frac{2}{17} [/tex]
The answer is 2/17
[tex] \frac{16}{17} - \frac{14}{17} [/tex] = 2/17
State whether the data described below are discrete or continuous, and explain why. The weights of dogs (in pounds) at a dog show
A. The data are discrete because the data can take on any value in an interval.
B. The data are discrete because the data can only take on specific values.
C. The data are continuous because the data can only take on specific values.
D. The data are continuous because the data can take on any value in an interval.
Answer: D. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation: When distinguishing between quantitative variables, they could be classed as either discreet or continuous. This difference between a discreet and continuous variable lies in whether the variable has a finite number of values or not. When a variable can only take up a certain number of values usually while numbers within a certain interval, then such varibak eis said to be finite. On the other hand variables which can take up any value within an interval are said to be continuous as they can take up an uncountable number of values within an interval. When weight is being recorded, it could take up an infinite number of values including decimal within an interval making it difficult to ascertain the number of possible values within the interval.

A circular arc has measure 8 cm and is intercepted by a central angle of 2.3 radians. Find the radius of the circle. Do not round any intermediate computations, and round your answer to the nearest tenth.
Answer:
3.5 cm
Step-by-step explanation:
Given the question:
A circular arc has measure 8 cm and is intercepted by a central angle of 2.3 radians. Find the radius of the circle. Do not round any intermediate computations, and round your answer to the nearest tenth.
Central angle in radian (θ) = 2.3 radian
Length of arc (s) = 8cm
Recall:
Length of arc (s) = radius (r) × central angle (θ)
8cm = radius × 2.3 rad
radius = 8 / 2.3
Radius = 3.478 cm
Radius = 3.5 cm

How do I solve for (2√5−√3)^2?
Answer:
[tex]23-4\sqrt{15}[/tex]
Step-by-step explanation:
So we want to simplify:
[tex](2\sqrt5-\sqrt3)^2[/tex]
Note that this is in the format:
[tex](a-b)^2[/tex]
And we know that this is the same as:
[tex](a-b)^2=a^2-2ab+b^2[/tex]
Let 2√5 be a and let √3 be b. Thus:
[tex](2\sqrt5-\sqrt3)^2\\=(2\sqrt5)^2-2(2\sqrt5)(\sqrt3)+(\sqrt3)^2[/tex]
Simplify:
[tex]=(4(5))-4(\sqrt5)(\sqrt3)+(3)\\=20-4\sqrt{15}+3\\=23-4\sqrt{15}[/tex]
And this cannot be simplified any further.

Why is the product of 1/4 times 1/5 less than each factor
The value of the number falls as the denominator rises, and the product of 1/4 and 1/5 is smaller than each factor.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
The complete question is:
Why is the product of 1/4×1/5 less than each factor
It is given that:
Two fractions are given:
1/4 = 0.25
1/5 = 0.20
1/5 < 1/4
The product of the two fractions: 1/4 and 1/5
= (1/4)(1/5)
= 1/20
Because the value of the number falls as the denominator rises, the product of 1/4 and 1/5 is smaller than each factor.
Thus, the value of the number falls as the denominator rises, and the product of 1/4 and 1/5 is smaller than each factor.

p = 8.8d + 16
A triangle has sides with lengths of 5x - 7, 3x - 4, and 2x - 6. What is the perimeter of triangle?
Answer:
10x -17
Step-by-step explanation:
The perimeter is the sum of the side lengths:
P = (5x -7) +(3x -4) +(2x -6)
Grouping like terms can make simplification easier:
P = 5x +3x +2x -7 -4 -6
P = 10x -17
What is the probability that a randomly selected day of a leap year (with 366 possible days) is in February?
Answer:
0.0792
Step-by-step explanation:
Probability is the likelihood that an event is going to occur. The formula for probability is:
Probability = number of favorable outcomes / total number of outcomes.
Normally in a year there are 365 days and in the month of February there are 28 days but during a leap year there are 366 days in the year and 29 days in the month of February.
Probability that a selected day of a leap year is in February = 29 / 366 = 0.0792
The probability that a selected day of a leap year falls in February is 0.0792

Which equation shows a slope of -5 and a y-intercept of (0,1) ?
Answer:
y = -5x + 1
Step-by-step explanation:
Y= mx +b
m = slope
b = y-intercept
y = -5x + 1
Answer:
y = -5x + 1
Step-by-step explanation:
Seeing the words "slope" and "y-intercept," I jump immediately to the slope-intercept form of the equation of a straight line: y = mx + b.
Here we have m = -5 and b = 1:
y = -5x + 1

Answer:i
i) 7/15
ii) 7/15
Step-by-step explanation:
total: 10
good: 7
bad: 3
i) both are good
p(both good) = 7/10 * 6/9 = 42/90 = 7/15
ii) one good & one bad
p(first good & second bad) = 7/10 * 3/9 = 21/90 = 7/30
p(first bad & second good) = 3/10 * 7/9 = 21/90 = 7/30
p(one good & one bad) = 7/30 + 7/30 = 14/30 = 7/15

The sum of two numbers is 48. Their difference is 38. Find the numbers.
Answer:
43 and 5
Step-by-step explanation:
Let's let the two unknown numbers be a and b.
Their sum is 48, therefore:
[tex]a+b=48[/tex]
And their difference is 38. In other words:
[tex]a-b=38[/tex]
We now have a system of equations. To solve, we can use substitution. First, add b to both sides in the second equation:
[tex]a=38+b[/tex]
Substitute this into the first equation:
[tex](38+b)+b=48[/tex]
Combine like terms:
[tex]2b+38=48[/tex]
Subtract 38 from both sides:
[tex]2b=10[/tex]
Divide both sides by 2:
[tex]b=5[/tex]
So, one of the numbers is 5.
The sum of them is 48. Therefore, the other number is 48-5 or 43.
So, our two numbers are 43 and 5.
And we're done!
Answer:
5 and 43

There are n machines in a factory, each of them has defective rate of 0.01. Some maintainers are hired to help machines working. Using Poisson approximations to answer the following questions and explain why we can use Poisson approximation.
(a) If one maintainer is responsible for 20 machines, what’s the probability that machines go defective and cannot be repaired on time?
(b) If three maintainers are responsible for 80 machines, what’s the probability that machines go defective and cannot be repaired on time?
(c) Assume n=300, then at least how many maintainers are required such that the probability machines cannot be fixed on time is less than 0.01?
Answer:
a) 1 - ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k!
b) 1 - ∑^(80x/d)_k=0 ((e^-λ) × λ^k) / k!
c) ∑²⁰ˣ_k=0 (3^k)/k! = 0.99e³
Step-by-step explanation:
Given that;
if n ⇒ ∞
p ⇒ 0
⇒ np = Constant = λ, we can apply poisson approximation
⇒ Here 'p' is small ( p=0.01)
⇒ if (n=large) we can approximate it as prior distribution
⇒ let the number of defective items be d
so p(d) = ((e^-λ) × λ) / d!
NOW
a)
Let there be x number of repairs, So they will repair 20x machines on time. So if the number of defective machine is greater than 20x they can not repair it on time.
λ[n0.01]
p[ d > 20x ] = 1 - [ d ≤ 20x ]
= 1 - ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k!
b)
Similarly in this case if number of machines d > 80x/3;
Then it can not be repaired in time
p[ d > 80x/3 ]
1 - ∑^(80x/d)_k=0 ((e^-λ) × λ^k) / k!
c)
n = 300, lets do it for first case i.e;
p [ d > 20x } ≤ 0.01
1 - ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k! = 0.01
⇒ ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k! = 0.99
⇒ ∑²⁰ˣ_k=0 (λ^k)/k! = 0.99e^λ
∑²⁰ˣ_k=0 (3^k)/k! = 0.99e³

If m∠NLO = 41° and m∠NLM = 88°, what is m∠OLM?
Answer:
47°
Step-by-step explanation:
Given that m<NLO = 41°, and m<NLM = 88°, according to angle addition postulate, m<OLM + m<NLO = m<NLM
Therefore, subtracting m<NLO from both sides will give us:
m<OLM = m<NLM - m<NLO
m<OLM = 88° - 41°
m<OLM = 47°
