Henry walks to and from school each day. after 100 days of school, he has walked 125 miles. How many miles does Henry walk to and from school?

Answers

Answer:

1 1/4

Step-by-step explanation:

Divide 125 by 100, which gets you 1.25 (also known as 1 1/4)

Henry walked 1.25 miles each day to and from school.

What is Division?

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that,

Henry walks to and from school each day.

Distance travelled by Henry in 100 days = 125 miles

In order to find the distance travelled by Henry in 1 day to and from school, divide the total distance by 100.

Distance travelled in 1 day = 125 / 100 = 1.25 miles

Hence the distance Henry walk to and from school is 1.25 miles.

The equation of line is y = ( 3/4 )x + 2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( 8 , 8 )

Let the second point be Q = Q ( 4 , 5 )

Now , the slope of the line between the two points is

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 5 - 8 ) / ( 4 - 8 )

Slope m = -3/-4

Slope m = 3/4

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 8 = 3/4 ( x - 8 )

On simplifying the equation , we get

y - 8 = ( 3/4 )x - 6

Adding 8 on both sides of the equation , we get

y = ( 3/4 )x + 2

Therefore , the value of A is y = ( 3/4 )x + 2

Hence , the equation of line is y = ( 3/4 )x + 2

What is a regression model?

When modeling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method (also known as dependent and independent variables). Simple linear regression is used when there is only one explanatory variable, and multiple linear regression is used when there are numerous variables. As opposed to multivariate linear regression, which predicts numerous correlated dependent variables as opposed to a single scalar variable, this phrase is more specific.

When modeling relationships with linear predictor functions, the model's unknown parameters are inferred from the data.

The logistic regression method can be used in situations when the dependent variable is discrete. In other words, the likelihood of situations like pass/fail, true/false, 0/1, and so on that are mutually incompatible are calculated using this method. A sigmoid curve depicting the relationship between the independent variable and the target variable, which can only take on one of two values, and probability, which has a value between 0 and 1, are both present.

What is the angle–side triangle inequality?

The angleside triangle inequality indicates that in a triangles, the larger the angle of a triangle, the larger is the side opposite the angle.

Similarly, the larger the side length of a side of a triangle, the larger is the angle opposite the specified side.

Based on the angle-side triangle inequality, we get;

∠QRW is the angle opposite to the side of length 45 units, and ∠RWQ is the angle opposite the side of length 47 units.

Therefore; m∠QRW < m∠RWQ

7. In triangle ΔRTW, ∠RTW is the angle opposite to the side of length 34 units, and ∠TWR is the angle opposite the side of length 35 units.

Therefore; m∠RTW < m∠TWR

In triangle ΔRST, ∠RST is the angle opposite to the side of length 35 units, and ∠TRS is the angle opposite the side of length 22 units.

Therefore; m∠RST > m∠TRS

9. In triangle ΔQRW, ∠RWQ is the angle opposite to the 47 unit long side and ∠QRW⇔ is the angle opposite the side of length 45 units.

Answers

The event  the number is even and less than 12 covers the entire sample space of this experiment.

What is sample space?

In probability theory, the set of all feasible outcomes or outcomes of an experiment or random trial is referred to as the sample space. The sample points, or potential ordered outcomes, are listed as elements in the set used to represent the sample space.

Given:

A number is selected at random from the set {2, 4, 6, 8, 10}.

Let's examine each instance:

A. There are more than two.

When we get number 2, this does not apply to the situation. 2 is equal to 2 and not greater, therefore.

B. The number is not divisible by 5, whereas 10 and 5 are. As a result, the sample space is not completely covered.

C. It's an even number or less than 12.

Let's note that every number from "2, 4, 6, 8, 10" is less than 12, indicating that the event's even portion has no bearing. This encompasses the whole sample area.

D. Neither the number is prime nor is it a composite.

There cannot be a number that is neither prime nor composite because they are mutually exclusive terms in mathematics. No number of the set is covered by this event.

E. The number's square root is less than 3.

This excludes the number 10, whose square root is approximately 3,16, which is greater than 3.

Hence, the event  the number is even and less than 12 covers the entire sample space of this experiment.

Find the component form of the resultant vector.
9) u = (-5, -2)
b =(3, 1)
Find: -u + b


Pls hurryyyyy

Answers

Answer:

the component form of the resultant vector is (-2, -1).

Step-by-step explanation:

To find the component form of the resultant vector, we need to add the corresponding components of the two input vectors. In this case, the x-component of the resultant vector is equal to the x-component of vector b minus the x-component of vector u, and the y-component of the resultant vector is equal to the y-component of vector b minus the y-component of vector u.

We can therefore write the component form of the resultant vector as follows:

-u + b = (-u_x + b_x, -u_y + b_y) = (-5 + 3, -2 + 1) = (-2, -1)

therefore, the component form of the resultant vector is (-2, -1).

Control lines are the horizontal lines drawn on the control chart. A control chart has several components. It has two control limits. They are represented by dashed lines. The lower one is called the lower control limit (LCL) and the upper one is called the upper control limit (UCL).

The control limits help us mark the highest (by UCL) and lowest (by LCL) error that is bearable. All those errors that occur between UCL and LCL are common errors/variations while the errors that occur above UCL or below LCL are the products with assignable causes variations.

The correlation values that represent the perfect linear relationship between x and y are = b) 1 and d) -1

Now first we need to understand what is meant by correlation,

The mutual relation or degree to which two or more quantities are mutually linear or related to each other, hence their degree or relation of correlation is qualified by correlation coefficient.

According to the question we need to find the correlation value that represents a perfect linear relationship between x and y

Since we know according to the definition of correlation, the perfect linear relationship between x and y could be represented if their magnitude is 1.

Both positive and negative values of magnitude 1 (i.e 1 and -1)  are defined as the linear relationship between x and y.

So, count up from a point on the line and count across to another point on the graph.

I started from -1, counted up 4 and counted 1 across to point (-1,3)

So your slope is 4/-1, which is the same as -4

The slope of a line from the given graph is -4. Therefore, option D is the correct answer.

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The predicted y-hat value for a diameter of 201 is 864. Interpret this predicted value.

If we choose to use a diameter of 201 for the experiment, the strength will be 786.6596.

Given, the experiment in which weld diameter and shear strength (in pounds) were measured for five distinct spot welds on steel produced the data that is included.

The gathered information and the regression equation are shown below.

Strength = -941.6992 + 8.5988×Diameter

we have to calculate the predicted y-hat value for the diameter value of 201.

Now, we are given the regression equation with the strength and diameter as the variables.

now, when we put the diameter equal to 201, the strength will be

Strength = -941.6992 + 8.5988×Diameter

Diameter = 201

Strength = -941.6992 + 8.5988×201

Strength = -941.6992 + 1,728.3588

Strength = 786.6596

So, the value of the strength be 786.6596
