Which type of triangle can be constructed with a 50° angle between two 8-inch sides? A. Equilateral B. Isosceles C. Scalene D. Obtuse.
The correct option is (C) Isosceles. An Isosceles triangle can be constructed with a 50° angle between two 8-inch sides.
This is because isosceles triangle having two sides that are equal in length, and have 50° angle, which is acute angle, that is less than 90°. This state that the remaining angle in the triangle must also be acute triangle, as the sum of all angles in a triangle must equal 180°.
This means that the remaining angle must be 80° (i.e. 180 - 50 = 80). An isosceles triangle is triangle consisting of two sides of equal length and two angles of equal measure. The two equal sides that make up the isosceles triangle are referred to as the base and the remaining side is height or altitude.

answer two questions about systems aaa and bbb: system aaa \text{\quad}start text, end text system bbb \begin{cases}x-4y
Two questions about systems aaa and bbb, the given system is:
System aaa: x = -1/3 and y = -7/3
System bbb: x = -1/3 and y = -7/3
To answer two questions about systems aaa and bbb, let's first clarify the given system:
System aaa:
x - 4y = 9
System bbb:
2x + y = -3
Question 1: Solve system aaa.
To solve system aaa, we'll use the method of substitution:
Step 1: Solve one equation for one variable.
From the first equation in system aaa, we can isolate x:
x = 4y + 9
Step 2: Substitute the expression from Step 1 into the other equation.
Substitute the expression for x in the second equation of system aaa:
2(4y + 9) + y = -3
Step 3: Simplify and solve for y.
8y + 18 + y = -3
9y + 18 = -3
9y = -3 - 18
9y = -21
y = -21/9
y = -7/3
Step 4: Substitute the value of y into the expression for x.
Using the first equation in system aaa:
x - 4(-7/3) = 9
x + 28/3 = 9
x = 9 - 28/3
x = (27 - 28)/3
x = -1/3
Therefore, the solution to system aaa is x = -1/3 and y = -7/3.
Question 2: Solve system bbb.
To solve system bbb, we'll use the method of substitution:
Step 1: Solve one equation for one variable.
From the second equation in system bbb, we can isolate y:
y = -2x - 3
Step 2: Substitute the expression from Step 1 into the other equation.
Substitute the expression for y in the first equation of system bbb:
x - 4(-2x - 3) = 9
Step 3: Simplify and solve for x.
x + 8x + 12 = 9
9x + 12 = 9
9x = 9 - 12
9x = -3
x = -3/9
x = -1/3
Step 4: Substitute the value of x into the expression for y.
Using the second equation in system bbb:
y = -2(-1/3) - 3
y = 2/3 - 3
y = 2/3 - 9/3
y = -7/3
Therefore, the solution to system bbb is x = -1/3 and y = -7/3.

A tank can hold 85 litres water . It's 30% filled. What percentage of the tank empty? Write answer in decimal and fraction
Answer:
59.50 liters (fraction from)
\(\dfrac{119}{2} \ in \ fraction \ form.\)
Step-by-step explanation:
30% of tank is filled. So, (100 - 30)% of tank is empty.
70% of tank is empty.
Capacity of the tank that is empty = 70% of 85 liters
In decimal form:

Sunil is thrice as old as his son. By taking Sunil's age as x years and his son's age as y years, write a linear equation in two variables to represent the statement. Express the equation in the form of ax+by+c=0 and indicate the values of a,b, and c
Answer:
Step-by-step explanation:
Let x be Sunil's age and y be his son's age.
Since Sunil is thrice as old as his son, we can write the equation x = 3y.
we could just rearrange the equation x = 3y
as x- 3y = 0
(or)
To express the equation in the form of ax + by + c = 0, need to find the values of a, b, and c.
a = 1
b = -3
c = 0
Therefore, the equation representing the statement "Sunil is thrice as old as his son" is x - 3y = 0.

if the population of 100 bacteria doubles every 15 min., how long will it take for population to reach 12,800 ?
Assuming that the bacteria population doubles every 15 minutes, it will take around 70.6 minutes for the population to increase from 100 to 12,800.
If the population of bacteria doubles every 15 minutes, it means that the growth rate is exponential. The initial population is 100, and we want to find the time it takes for the population to reach 12,800.
To solve this problem, we can use the exponential growth formula:
N(t) = N0 * 2⁽ᵗ/ᵀ⁾
where:
N0 = initial population (100 bacteria)
N(t) = population at time t
t = time elapsed
T = time it takes for the population to double (15 minutes)
We want to find the time it takes for the population to reach 12,800 bacteria, so we can set N(t) to 12,800:
12,800 = 100 * 2⁽ᵗ/¹⁵⁾
Dividing both sides by 100:
128 = 2⁽ᵗ/¹⁵⁾
Taking the logarithm (base 2) of both sides:
log2(128) = t/15
t = 15 * log2(128)
Using a calculator, we can solve for t:
t ≈ 70.6 minutes
Therefore, it will take approximately 70.6 minutes for the population of bacteria to reach 12,800, if the population doubles every 15 minutes.

A single number that estimates the value of an unknown parameter is called a _______ estimate.
Answer:
A single number that estimates the value of an unknown parameter is called a point estimate.
Step-by-step explanation:
Don't see the point (haha) of elaborating
Explain the error in the work and how you might prevent it.
The error is \(12x^2 - 14x = - 26x^2\) because 12x² and 14x are unlike terms, so we can not add them
To prevent it the dividend must be written as \(6x^3 + 0x^2 - 14x + 1\)
Now, According to the question:
In the division, you must arrange the dividend according to the greatest power of the variable, and put 0 as a coefficient of the missing term to avoid adding, unlike terms.
Example:
If the dividend is \(3x^3 - 2x + 5\), then you must write it as \(3x^3 + 0x^2 - 2x + 5\)
Let us solve our question
∵ The dividend is \(6x^3\) + 1 - 14x
→ You must arrange it from the greatest power of x
∴ The dividend is \(6x^3\) - 14x + 1
∵ The term of x² is missing
→ Write it in the dividend with a coefficient of 0
∴ The dividend is \(6x^3 + 0x^2 - 14x + 1\)
The error is the adding of unlike terms
∵ \(6x^3\)- 14x + 1 ÷ 3x + 6 = 2x² and [ \(6x^3\) - 14x + 1 - \(6x^3\) - ( \(6x^3\) + \(12x^2\))]
∵\([6x^3 - 14x + 1 - 6x^3 - (6x^3 + 12x^2)] = 6x^3 - 14x + 1 - 6x^3 - 12x^2\)
∵ \(6x^3 - 14x + 1 - 6x^3 - 12x^2 = 0 - 12x^2 - 14x + 1\)
∵\(0 - 12x^2 - 14x + 1 = -26x^2 + 1\) ⇒ error
∴ The error is -12x² - 14x = - 26x² because 12x² and 14x are unlike terms,
so we can not add them
→ To prevent it, write 0 as a coefficient of the missing term
∵ The missing term is the term of x²
∴ Add to the dividend the term 0x²
∴ The dividend must be written as \(6x^3 + 0x^2 - 14x + 1\)

The standard normal distribution becomes smaller.
What is standard deviation?
Your dataset's average level of variability is represented by the standard deviation. It reveals the average deviation of each statistic from the mean. A low standard deviation denotes that values are grouped close to the mean, whereas a large standard deviation shows that values are often far from the mean.Think about the following data: 2, 1, 3, 2, 4. The average and the sum of squares representing the observations' variances from the mean will be 2.4 and 5.2, respectively.

a certain star is 5.4 x 10^2 light years away from earth. one light year is about 5.9 x 10^12 miles. how many miles away from earth is the star?
Answer:
2.537 x 10¹⁵ miles
Step-by-step explanation:
We are given the following:
1 light year = 5.9 x 10¹² miles
Distance of the star = 4.3 x 10² light years
To get this we just convert the distance of the star in light years into miles.
We cancel out the light years and then we are left with:
In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.
Coefficients:
4.3 x 5.9 = 25.37
Exponents of 10:
10² x 10¹² = 10⁽²⁺¹²⁾=10¹⁴
Then we combine them again to form a scientific notation:
25.37 x 10¹⁴
But since the standard in writing a scientific notation, the coefficient needs to be a number from 1-9, we need to move the decimal. When we move the decimal to the right or left, we change the exponent of the power of 10. Since we will move it once to the left, we add 1.
The answer will then be:
2.537 x 10¹⁵ miles

A server whose utilization factor is 1 3 experiences Poisson arrivals at the average rate of 2 per hour. If the service time for each arriving unit follows an exponential distribution, what is the average service time for each arriving unit in minutes? (a) 3 (b) 6 (c) 9 (d) 10
Poisson arrivals occur on a server with a utilization factor of 13 at a typical rate of 2 per hour. The mean service time in minutes for each arrival unit is 10 if the service time for each unit has an exponential distribution. Here option D is the correct answer.
We can use Little's law to relate the average number of customers in the system to the average time they spend in the system:
L = λW
where L is the average number of customers in the system, λ is the arrival rate, and W is the average time spent in the system.
Since the server utilization factor is 1/3, we know that the service rate is 3 times the arrival rate:
μ = 3λ = 6
We can then use the formula for the expected value of the exponential distribution with rate parameter μ to find the average service time:
E[X] = 1/μ
E[X] = 1/6 hour = 10 minutes
Little's law is used to relate the average number of customers in the system to the average time they spend in the system, and the service rate is calculated from the given utilization factor. The formula for the expected value of the exponential distribution is then used to find the average service time, which is 10 minutes.

Then we find the average range across all samples:R = (155 - 100 + 142 - 2 + 140 - 110 + 132 - 114 + 142 - 3) / 5 = 109.2 seconds (rounded to three decimal places).
c) The Upper Control Limit (UCL) and Lower Control Limit (LCL) using 3-sigma can be calculated by adding and subtracting three times the standard deviation from the average:UCL = x + (3 * R / d2) = 114.118 + (3 * 109.2 / 1.693) = 348.351 seconds (rounded to three decimal places).LCL = x - (3 * R / d2) = 114.118 - (3 * 109.2 / 1.693) = -120.115 seconds (rounded to three decimal places).
d) The Upper Control Limit Range (UCLR) and Lower Control Limit Range (LCLR) using 3-sigma can be calculated by multiplying the average range by the appropriate factor:UCLR = R * D4 = 109.2 * 2.115 = 231.108 seconds (rounded to three decimal places).LCLR = R * D3 = 109.2 * 0 = 0 seconds.
