Claire tossed a die onto a black-and-red checkerboard. What is the probability that it will land with a value less than 4 on a red square?

show work pls and Thanks!!

Answer:

64 feet

Explanation:

Multiply 16 by 4 to get the depth after 4 minutes.

The perimeter of the rectangle is 60 cm.

We have,

The square perimeter = 20 cm

This means,

Each side of the square = 20/4 = 5 cm

Now,

From the rectangle figure,

Length = 5 + 5 + 5 + 5 = 20 cm

Width = 5 + 5 = 10 cm

So,

The perimeter of the rectangle.

= 2 (length + width)

= 2 x (20 + 10)

= 2 x 30

= 60 cm

Thus,

The perimeter of the rectangle is 60 cm.

Thus, the test for homogeneity follows the same procedures as the test for independence because the assumptions for performing the chi-square test for independence and chi-square test for homogeneity are the same.

The procedures for the chi-square test of homogeneity are the same as for the chi-square test of independence. The data is different for both tests. Tests of independence are used to determine whether there is a significant relationship between two categorical variables from the same population. One population is segmented based on the value of two variables. So there will be a column variable and a row variable.

The chi-square test of homogeneity of proportions can be used to compare population proportions from two or more independent samples, determining whether the frequency counts are distributed identically among different populations.

The null hypothesis and alternative hypothesis in the notation for the individual t-test for testing the slope coefficient associated with a simple linear regression are given below:

Null hypothesis: H₀: β₁ = 0

Alternative hypothesis: Hₐ : β₁ ≠ 0

The hypothesis test is used to determine whether or not there is sufficient evidence to support the alternative hypothesis that the slope of the regression line is not equal to zero. The null hypothesis is that the slope of the regression line is equal to zero.

Therefore, we will use the individual t-test for the slope coefficient to test the hypothesis regarding the slope of the regression line. The formula for the t-test for the slope coefficient is given below:

t = (b₁– β₁) / SEb₁

Where b₁ is the sample slope coefficient β₁ is the hypothesized value of the slope coefficient (i.e., 0) SEb₁ is the standard error of the slope coefficient.

Step-by-step explanation:

Ima be real I cant really explain but i think that's right

The factor that does NOT control the stability of a slope is the angle of repose for intact bedrock. The angle of repose refers to the steepest angle at which a pile of loose material remains stable without sliding. It is mainly applicable to loose materials like soil and granular substances, not intact bedrock.

Bedrock stability depends on factors such as its strength, fracturing, and geological properties, rather than the angle of repose. Factors that control the stability of a slope include whether the slope is rock or soil. Rock slopes tend to be more stable than soil slopes due to the cohesive nature of intact rock.

The amount of water in the soil also affects slope stability, as excessive water can increase pore pressure and reduce the shear strength of the soil, leading to slope failure. Additionally, the orientation of fractures, cleavage, and bedding in the rock can influence slope stability by creating planes of weakness or strength.

To summarize, while the angle of repose is a significant factor in slope stability, it is not applicable to intact bedrock. The stability of a slope is influenced by the type of material (rock or soil), the presence of water, and the orientation of fractures and bedding.

Here you go mate

Step 1

30x-16=14  Equation/Question

Step 2

30x-16=14 Simplify

30x-16=14

Step 3

30x-16=14  Add 16 to sides

30x=30

Step 4

30x=30  Divide sides by 30

answer

x=1

Hope this helps

Step-by-step explanation: To solve for X, we'll need to move all terms that don't contain X to the right and solve.

1. Add 16 to both sides

30x - 16 + 16 = 14 + 16

30x = 30

2. Divide both sides by 30

\(\frac{30x}{30} =\frac{30}{30}\)

Therefore, your answer is 1.

Answer:

  C.  142°

Step-by-step explanation:

You want the angle between vectors u=3i+√3j and v=-2i-5j.

There are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:

  u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest

You can find the angles of the vectors individually, and subtract those:

  u = |u|∠α

  v = |v|∠β

  θ = α - β

When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:

  \(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)

This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.

A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.

__

Additional comment

The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.

The dot-product relation will work with 3D vectors as well as 2D vectors.

Answer: ∠WZY=150°

Step-by-step explanation:

Analysis :

ΔWXY is an isosceles triangle

perpendicular to WX intersecting:

XY at A

∠XWA = 21°

∠WXA = 90°-21° = 69°

Now, ΔXYZ is equilateral,

∠XYZ = ∠YXZ = 60°

Then,

∠WXZ = ∠WXA - ∠YXZ

= 69°-60°

= 9°

Since the angles of a triangle = 180°

∠WZY = ∠WZX = 180° - ∠XWA - ∠WXZ

= 180° - 21° - 9°

= 150°

The mean in math means the sum of all the numbers divided by how many numbers there are. There is no information about how many numbers there are nor any information of which numbers exist and which numbers don't.

The data set only tells us the first number, last number, and median-- things a box-and-whisker plot would tell us; perhaps a different way of representing data would work better to help us find the median like a dot plot or a bar graph.

The analysis of variance to simultaneously study the effects of several independent factors on one dependent variable is the right response that most accurately describes a factorial ANOVA. Correct option is A.

Factorial ANOVA is a statistical technique used to analyze the effects of two or more independent variables (factors) on a single dependent variable. In a factorial ANOVA, each independent variable is referred to as a factor, and the levels of each factor are combined to create different groups or conditions.

By simultaneously manipulating multiple independent variables, a factorial ANOVA allows for the examination of main effects (the effect of each independent variable on the dependent variable) and interaction effects (the combined effect of multiple independent variables on the dependent variable).

This analysis helps to determine whether there are significant differences among the groups or conditions and to understand the individual and combined effects of the independent variables on the dependent variable.

Therefore, option a accurately describes the purpose and methodology of a factorial ANOVA.

Addition is determining the total value or summing two or more numbers. Addition is one of the four basic operations in mathematics. The other basic operations are subtraction, multiplication and division.

Total debt = first amount Beth borrowed + second amount Beth borrowed
