Answer:

a model is an estimate or approximation of a data set. In the real world, there are too many variables to know exactly what will happen. However, if a model is a good fit, then it can be used to make predictions about what will happen. With a useful model, a predicted value should be a good estimate of an observed value.

Step-by-step explanation:

George Box's statement "All models are wrong, but some are useful" suggests that while models are imperfect, they still offer valuable insights and utility in understanding complex systems.

George Box's statement "All models are wrong, but some are useful" acknowledges the inherent imperfections of models, emphasizing that they are simplified representations of reality.

Models, by nature, cannot perfectly capture every detail of a complex system.

However, despite their inaccuracies, models still hold utility in providing insights and aiding decision-making processes.

This perspective suggests that while models may not be entirely accurate, they can still offer valuable understanding and predictive power.

Box's statement encourages a balanced approach, where users recognize the limitations of models while leveraging their practical usefulness.

In essence, it underscores the importance of not dismissing models due to their imperfections but rather using them judiciously in specific contexts where they can provide meaningful insights.

Answer:

[tex]\large\boxed{4\vec{u}+3\vec{v}=<-26,\ 26>}[/tex]

Step-by-step explanation:

[tex]\vec{u}=<-5,\ 2>;\ \vec{v}=<-2,\ 6>\\\\4\vec{u}=<(4)(-5),\ (4)(2)>=<-20,\ 8>\\\\3\vec{v}=<(3)(-2),\ (3)(6)>=<-6,\ 18>\\\\4\vec{u}+3\vec{v}=<-20,\ 8>+<-6,\ 18>=<-20+(-6),\ 8+18>=<-26,\ 26>[/tex]

The result of the vector addition and scalar multiplication operation 4u + 3v, with u=<-5,2> and v=<-2,6>, is <-26,26>.

Given the vectors u=<-5,2> and v=<-2,6>, we can compute the expression 4u + 3v by performing vector addition and scalar multiplication.

First, we multiply the vectors by their respective scalars, which results in 4u = 4*(-5,2) = <-20,8> and 3v = 3*(-2,6) = <-6,18>.

Then we add the resulting vectors together. The x-components add together to produce the new x-component and the y-components add together to produce the new y-component. So 4u + 3v = <-20,8> + <-6,18> = <-26,26>.

This demonstrates the distributive property and the principles of vector addition and scalar multiplication.

Step-by-step explanation:

Let s represent the length of the shorter part (in feet). Then the longer part has length (s+1), and the total length of the two parts is ...

  s + (s+1) = 25

  2s = 24 . . . . . . . subtract 1, simplify

  s = 12 . . . . . . . . . divide by 2; the length of the shorter part

  s+1 = 13 . . . . . . . the length of the longer part

The shorter part is 12 feet long; the longer part is 13 feet long.

_____

Comment on this problem type

You will note that the smaller number is half the difference of the total length (25) and the difference in lengths (1). This is the generic solution to a "sum and difference" problem. The smaller number is half the difference of the given numbers, and the larger number is half their sum: (25+1)/2 = 13.

Answer:

8 and 17

Step-by-step explanation:

Let's say the smaller number is x. The question says "The longer part is one foot more than twice the shorter part" so we reverse that using x which becomes x+2x+1=25 and x=8 so 8+8*2+1=25 => 8+17=25 so the answer is 8 and 17, please like and 5 star rate

Answer:

The measure of arc HD is 20°

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

In the triangle of the figure , the measure of the third  interior angle is equal to

180°-92°-38°= 50°

50°=(1/2)[(102+18)°-arc HD]

100°=[120°-arc HD]

arc HD=120°-100°=20°

Answer:

 arc HD = 20°

Step-by-step explanation:

Let point N be the point where secant RL intersect the circle, point M be the point of intersection for chords NL and KH, and point S be the vertex of the triangle formed by secants KH and RD.

It is given that m∠SRM = 38∘ and m∠RMS = 92∘. Use the Triangle Sum Theorem to determine m∠MSR.

m∠MSR = 180° − 92∘ − 38∘  = 50∘

It is also given that mPN = 18∘ and mNK = 102∘. So, mPK = 18∘ + 102∘ = 120∘.

If a tangent and a secant, two tangents, or two secants intersect in the exterior of a circle, then the measure of the angle formed is half the difference of the measures of its intercepted arcs. So,  

m∠MSR= 1 /2 (mPK − mHD)

Substitute the known values and solve for mHD.

50∘ = 1/2 (120∘ − mHD)

Multiply by 2.

100 = 120∘ − mHD

Simplify.

mHD = 20

Therefore, the measure of arc HD is 20∘.

If a triangle is not isosceles, then it's not equilateral.

I would personally go w/ b or c

There is exactly one solution for this triangle, and the correct answer is:  b. 1 solution

To determine the number of solutions for the given triangle with angles A, C, and side c, we can use the Law of Sines, which states that in any triangle:

[tex]\[\frac{\sin(A)}{a} = \frac{\sin(B)}{b} = \frac{\sin(C)}{c}\][/tex]

 Given:

- Angle A = 90 degrees (since it is a right angle, we assume A is the right angle for the purpose of this solution)

- Angle C = 4 degrees

- Side c = 12 units (opposite to angle C)

Since angle A is 90 degrees, we know that this triangle is a right-angled triangle. In a right-angled triangle, the other two angles must add up to 90 degrees. We are given one of those angles, C, which is 4 degrees. Therefore, the third angle, B, which is opposite side b, can be calculated as:

[tex]\[B = 90^\circ - C = 90^\circ - 4^\circ = 86^\circ\][/tex]

 Now, we have all three angles: A = 90°, B = 86°, and C = 4°. The sum of angles in any triangle is 180 degrees, and in this case:

[tex]\[A + B + C = 90^\circ + 86^\circ + 4^\circ = 180^\circ\][/tex]

 This confirms that the angles are consistent with the angles of a triangle.

Next, we can find the length of side b using the Law of Sines:

[tex]\[\frac{\sin(B)}{b} = \frac{\sin(C)}{c}\][/tex]

[tex]\[\frac{\sin(86^\circ)}{b} = \frac{\sin(4^\circ)}{12}\][/tex]

Since 86° and 4° are acute angles and sine of an acute angle is unique, there will be a unique positive value for b. This means there is only one possible length for side b that will satisfy the conditions of the triangle.

 Therefore, there is exactly one solution for this triangle, and the correct answer is:

b. 1 solution

Step-by-step explanation:

You might see this a bit easier if you change the 5/4 * pi into degrees.

pi/180 = 5/4*pi / x                   This is the proportion. Change 5/4 into a decimal

pi/180 = 1.25 *pi / x                 Cross multiply

x * pi = 1.25 pi * 180                Divide by pi

x = 1.25 * 180

x = 225 degrees.

We will see that the probability of not winning the prize is equal to 0.38, so the correct option is b.

In this experiment, we have two possible outcomes.

One outcome is winning the prize, with a probability P and the other outcome is losing, with a probability Q.

Because there are only two outcomes we will have that:

P + Q  = 1

We know that P = 0.62, replacing that we get:

0.62 + Q = 1

Q = 1 - 0.62 = 0.38

So we conclude that the probability of not winning the prize is 0.38, then the correct option is b.
