The answer is:

5/4

Work/explanation:

Let's work out the slope of the line.

The equation is in y = mx + b form where m = slope; b = y intercept.

Similarly, in y=5/4x - 7/4, the slope is 5/4.

Answer:

x=4

Step-by-step explanation:

(x-4)/(x+5)(x-1)

For this to be equal to zero, the numerator must be zero and the denominator not equal to zero

x-4 = 0

The standard error of the mean for each sampling situation (assuming a normal population) is:

a) SEM = 13

b) SEM = 6.5

c) SEM = 3.25

In statistics, the standard error (SE) is the measure of the precision of an estimate of the population mean. It tells us how much the sample means differ from the actual population mean. The formula for the standard error of the mean (SEM) is:

SEM = σ / sqrt(n)

Where σ is the standard deviation of the population, n is the sample size, and sqrt(n) is the square root of the sample size.

Let's calculate the standard error of the mean for each given sampling situation:

a) Given o = 52 and n = 16:

The standard deviation of the population is given by σ = 52.

The sample size is n = 16.

The standard error of the mean is:

SEM = σ / sqrt(n) = 52 / sqrt(16) = 13

b) Given o = 52 and n = 64:

The standard deviation of the population is given by σ = 52.

The sample size is n = 64.

The standard error of the mean is:

SEM = σ / sqrt(n) = 52 / sqrt(64) = 6.5

c) Given o = 52 and n = 256:

The standard deviation of the population is given by σ = 52.

The sample size is n = 256.

The standard error of the mean is:

SEM = σ / sqrt(n) = 52 / sqrt(256) = 3.25

The chi-square test of independence is typically used to analyze the relationship between two variables when both variables are nominal, the two variables have been measured on different individuals and the observations on each variable are within-subjects in nature. The answer is  D. all of the above

The chi-square test of independence is a statistical test that is used to determine if there is a significant association between two categorical variables. It is commonly used when both variables are nominal, meaning they consist of categories or groups rather than numerical values.

When conducting the chi-square test of independence, the data is typically collected by measuring the two variables on different individuals or units.

For example, researchers may collect data on the gender (nominal variable) and political affiliation (nominal variable) of different individuals and analyze whether there is a relationship between the two variables.

The test examines the observed frequencies of the different categories in a contingency table and compares them to the expected frequencies under the assumption of independence. If the observed and expected frequencies significantly differ, it suggests that there is an association between the two variables.

Therefore, the chi-square test of independence is applicable when both variables are nominal and the data is collected on different individuals. This allows researchers to investigate the relationship between the variables and determine if they are associated or independent.

Answer: 64%

Step-by-step explanation:

The score you have entered means that the individual who took the test is at the sixty-fourth percentile – their percentile rank is 64%. This means that the student had a test score greater than or equal to 64% of the reference population. Conversely, 36% of students scored equal to or higher than the individual tested.

Answer:

95

Step-by-step explanation:

To find the average you take the sum of the scores and then divide it by the number of exams. Let x equal the score Lucy must obtain on the next math test.

\(\frac{85+64+76+x}{4} =80\)

Add the scores and multiply both sides by 4

225 + x = 320

Subtract 225 from both sides

x = 95

Answer: 9/16 as a decimal is 0.5625

9-16-as-a-decimal-is-0.5625

Let's look into the two methods to write 9/16 as a decimal.

Explanation:

Method 1: Writing 9/16 as a decimal using the division method

To convert any fraction to decimal form, we just need to divide its numerator by denominator.

Here, the fraction is 9/16 which means we need to perform 9 ÷ 16

This gives the answer as 0.5625. So, 9/16 as a decimal is 0.5625

Method 2: Writing 9/16 as a decimal by converting the denominator to powers of 10

Step 1: Find a number such that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on.

Step 2: Multiply both numerator and denominator by that number to convert it into it's an equivalent fraction.

Step 3: Then write down just the numerator, putting the decimal point in the correct place, that is, one space from the right-hand side for every zero in the denominator.

9/16 = (9 × 625) / (16 × 625) = 5625/10000 = 0.5625

Irrespective of the methods used, the answer to 9/16 as a decimal will always remain the same.

You can also verify your answer using Cuemath's Fraction to Decimal Calculator.

Thus, 9/16 as a decimal is 0.5625

The cost of the apples is 2.9 dollars.

The cost of the bananas is 5.7 dollars.

The total cost is 6 dollars, each apple cost $1.50 each banana cost $.30 and there’s two more bananas then apples.

Therefore,

let

x = number of apples

y = 2x

where

Therefore, using equations,

1.5(x) + y(0.30) = 6

Hence,

where

y = 2x

1.5(x) + 2x(0.30) = 6

1.5x + 0.6x = 6

2.1x = 6

divide both sides by 2.1

x = 6 / 2.1

x = 2.9 dollars

y = 2(2.9) = 5.7 dollars

Therefore, when DE is 500 yards and BC is 100 yards in the triangle ADE, the distance is 400 yards.

what is triangle ?

Given that it has three sections and three vertices, a triangle qualifies as a polygon. It belongs to the fundamental geometric shapes. Triangle ABC is the term used to refer to a triangle with the sides A, B, and C. So when three factors are not collinear, a unique planar and triangle in Geometric shapes are discovered. Triangles are polygons because they have three parts and three corners. The points where the four sides of the triangle converge are referred to as the triangle's corners. Three triangle angles are multiplied to yield 180 degrees.

given

triangle ABC = sinθ = 100 / AC = AC = 100

triangle ADE = sinθ = 500 / AE = AE = 500

distance across DE - BC = 500 - 100

= 400 yards

Therefore, when DE is 500 yards and BC is 100 yards in the triangle ADE, the distance is 400 yards.

The x-intercept and the y intercept of the graph of 6x - 3y = 36 are x = 6 and y = -12

How to determine the x-intercept and the y intercept of the graph?

From the question, we have the following parameters that can be used in our computation:

6x - 3y = 36

Set y to 0 to determine the x-intercept

So, we have the following representation

6x = 36

Divide by 6

x = 6

Set x to 0 to determine the y-intercept

-3y = 36

Divide by -3

y = -12

hence, the intercepts are x = 6 and y = -12
