A triangle has two sides of 8 and 15. What is the largest possible whole number length for the third side?
Answers
Answer:
Largest possible value for the 3rd side can be 22.
Step-by-step explanation:
Property of sides of a triangle:
If two sides of a triangle are \(a\) and \(b\) long, then the length of third side \(c\) must be:
\((a+b) > c\)
i.e. the sum of two sides \(a\) and \(b\) must be greater than the third side \(c\).
So, to find the largest possible value:
\(a = 8\\b= 15\)
\(a+b=23\)
Largest possible value of \(c\) can be lesser than 23.
i.e. 22 can be the largest possible value of the third side.

How to calculate the total perimeter?We are told that Isabelle had a five sided chicken coop in her yard and that the length was equal in all the sides.
Now, we need to find the total perimeter of the chicken coop.
The length of one side of the coop from online sources is 3√5 yards.
Since the coop is 5 sided, it means that it is a pentagon and we know that;
Perimeter of a pentagon = 5a
Where a is length of one side of the pentagon. Thus;

if you have $4 in quarter and dimes and 34 coins how many quarter and dimes are there
Answers
Since we know the total number of coins is 34, we can set up the equation:
x + y = 34
We also know that the total value of the coins is $4. We can convert the number of quarters to dollars by multiplying by 0.25, and convert the number of dimes to dollars by multiplying by 0.10. Then we can set up another equation:
0.25x + 0.10y = 4
Now we have two equations with two variables. We can solve for x and y by using substitution or elimination.
Using substitution:
x + y = 34 --> y = 34 - x
0.25x + 0.10y = 4
0.25x + 0.10(34 - x) = 4
0.25x + 3.4 - 0.10x = 4
0.15x = 0.6
x = 4
y = 34 - x = 30
Therefore, there are 4 quarters and 30 dimes in the collection of coins.
Valor absoluto de 0.001
Answers
The absolute value of 0.001 is 0.001. This means that regardless of the context in which 0.001 is used, its absolute value will always be 0.001, as it is already a positive number.
The absolute value of a number is the non-negative magnitude of that number, irrespective of its sign. In the case of 0.001, since it is a positive number, its absolute value will remain the same.
To understand why the absolute value of 0.001 is 0.001, let's delve into the concept further.
The absolute value function essentially removes the negative sign from negative numbers and leaves positive numbers unchanged. In other words, it measures the distance of a number from zero on the number line, regardless of its direction.
In the case of 0.001, it is a positive number that lies to the right of zero on the number line. It signifies a distance of 0.001 units from zero. As the absolute value function only considers the magnitude, without regard to the sign, the absolute value of 0.001 is 0.001 itself.
Therefore, the absolute value of 0.001 is 0.001. This means that regardless of the context in which 0.001 is used, its absolute value will always be 0.001, as it is already a positive number.

Answers
Independent events are not affected by previous events, that is, the probability of a new event doesn't change from the previous event. However, disjoint sets mean they don't have any data in common, which means the intersection of such sets is impossible. In other words, the events are exclusive, if one occurs, then the other can't occur.
Having said that, we can deduct that scenario 1 represents an independent exclusive event because the occurrence of one event excludes the other. The main reason is that there's just one orange marble.

the criteria used when deciding upon the inclusion of a variable are A - Theory, B - t-statistic, C - Bias, and D - Adjusted R^2.
When deciding upon the inclusion of a variable, the following criteria are commonly used:
A - Theory: Theoretical justification is often considered to include a variable in a model. It involves assessing whether the variable is relevant and aligns with the underlying theory or conceptual framework.
B - t-statistic: The t-statistic is used to determine the statistical significance of a variable. A variable with a significant t-statistic suggests that it has a meaningful relationship with the dependent variable and may be included in the model.
C - Bias: Bias refers to the presence of systematic errors in the estimation of model parameters. It is important to consider the potential bias introduced by including or excluding a variable and assess whether it aligns with the research objectives.
D - Adjusted R^2: Adjusted R^2 is a measure of the goodness of fit of a regression model. It considers the trade-off between the number of variables included and the overall fit of the model. Adjusted R^2 helps in assessing whether the inclusion of a variable improves the model's explanatory power.

Answers
Using the concepts of statistics, we got that at least 79 is the minimum size of the sample needed in order to have a margin of error of two minutes or less, when we need to construct a 95% confidence interval for the mean length of time.
We have mean as 357.9minutes and standard deviation as 20.18 minutes.
To have the margin error 2 minutes or less than it we need to take
Z-score of the given sample distribution which is given by:
Z=(X-μ)/σ
The z-score measures how many standard deviations the measure is above or below the mean.Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .Here ,μ=357.9,σ=20.18,X=?,Z=95/100
=>95/100=(X-357.9)/20.18
=> -0.95×20.18=X-357.9
=>X=-357.9+0.95×20.18
=>X=-357.9+19.171
>X=-338.729
When X=-338.729,the p score is around 79.
Hence, when I want to construct a 95% confidence interval for the mean length of time of the flight in 2018 based on a sample of flights in 2018., the minimum size of the sample needed in order to have a margin of error of two minutes or less is 79.

The optimal values of these parameters are:
a. β₁ = 0

The linear regression y = β1 + β2x + e, assuming that the sum of squared errors (SSE) takes the following form:
SSE = 382 + 681 + 382 + 18β1β2
Derive the partial derivatives of SSE with respect to β1 and β2 and solve the optimal values of these parameters.
Given that SSE = 382 + 681 + 382 + 18β1β2 ∂SSE/∂β1 = 0 ∂SSE/∂β2 = 0
Now, we need to find the partial derivative of SSE with respect to β1.
∂SSE/∂β1 = 0 + 0 + 0 + 18β2 ⇒ 18β2 = 0 ⇒ β2 = 0
Therefore, we obtain the optimal value of β2 as 0.
Now, we need to find the partial derivative of SSE with respect to β2. ∂SSE/∂β2 = 0 + 0 + 0 + 18β1 ⇒ 18β1 = 0 ⇒ β1 = 0
Therefore, we obtain the optimal value of β1 as 0. Hence, the partial derivative of SSE with respect to β1 is 18β2 and the partial derivative of SSE with respect to β2 is 18β1.
Thus, the optimal values of β1 and β2 are 0 and 0, respectively.
Therefore, the answers are: a. β₁ = 0 b. β₂ = 0

The Lewiston Company issues 23-year bonds, but it pays nocoupon. Calculate the price per $1,000 face value of thiszero-coupon bond using an interest rate of 6.7%. Answer to thenearest cent.
Answers
The price per $1,000 face value of the zero-coupon bond issued by the Lewiston Company is approximately $288.12.
To calculate the price of the zero-coupon bond, we can use the present value formula:
Price = Face Value / (1 + Interest Rate)^(Number of Years)
In this case, the face value is $1,000, the interest rate is 6.7%, and the number of years is 23.
Price = 1000 / (1 + 0.067)^23 = 1000 / 2.871 = $348.35
However, this value represents the future value of the bond. To determine the present value, we need to discount it to today's value. To do that, we can divide the future value by (1 + Interest Rate).
Present Value = Price / (1 + Interest Rate) = 348.35 / (1 + 0.067) = $288.12 (rounded to the nearest cent)
The price per $1,000 face value of the zero-coupon bond issued by the Lewiston Company, using an interest rate of 6.7%, is approximately $288.12. Zero-coupon bonds are sold at a discount to their face value because they do not pay any periodic interest payments. The price reflects the present value of the bond, taking into account the time value of money and the specified interest rate.

The triangles are similar by the AA similarity criterion since they have two pairs of congruent angles (41° and 109°, and 30°). Therefore, the answer is B. AA.
What is triangle?A triangle is a polygon that has three sides, three vertices, and three angles. It is the simplest polygon in Euclidean geometry and one of the most studied shapes in mathematics. The sum of the three angles in a triangle is always 180 degrees, and the length of one side of a triangle is always less than the sum of the other two sides. There are many different types of triangles, including equilateral triangles (where all sides are equal), isosceles triangles (where two sides are equal), and scalene triangles (where no sides are equal). Triangles are used in many areas of mathematics and science, including trigonometry, geometry, and physics.
Here,
To determine whether the two triangles are similar using AA similarity, we need to compare the angles of both triangles.
Triangle 1 has angles 41°, 30°, and 109°.
Triangle 2 has angles 30°, 41°, and 109°.
We see that the two triangles have two pairs of congruent angles, namely 41° and 41°, and 109° and 109°. Therefore, the two triangles are similar by the AA similarity criterion.
Note that the order of the angles does not matter when comparing triangles for similarity.

Answers
Answer:
y=1/6x-6
Step-by-step explanation:
The first step is to set up the equation. Since the lines are parallel the slopes will be the same.
Note: y=mx+b; m is the slope and b is the y-intercept
Since we know that the slopes are the same all we have to do is plug in (12,0) in the equation to find b (y-intercept),
0=1/6(12)+b
0=6+b
-6=b
Now that we know b all we have to do is put it in the formula y=mx+b
y=1/6x-6.
Answer:
y = (1/6)x - 2
Step-by-step explanation:
"Parallel" means "has the same slope as..." so the slope of the line you want is 1/6.
y = (1/6)x + b where b is the y-intercept (now, find it using the point (12, 0) ).
0 = (1/6)(12) + b
