Answer:

x= 1

y= 3

Step-by-step explanation:

21(-2+y) +7y = 42

-42 +28y+42

28y = 42+42

28y= 84

divide both sides y= 3

x= -2+3 x=1

The  theoretical fractional probability that the first number is greater than the second number is 5/12.

To find the theoretical fractional probability that the first number rolled is greater than the second number when rolling a six-sided die two times,

Consider all possible outcomes of the two rolls.

(1,1) (1,2), (1, 3), (1,4), (1, 5), (1, 6)

(2,1) (2,2), (2, 3), (2,4), (2, 5), (2,6)

(3,1) (3,2), (3, 3), (3,4), (3, 5), (3, 6)

(4,1) (4,2), (4, 3), (4,4), (4, 5), (4, 6)

(5,1) (5,2), (5, 3), (5,4), (5, 5), (5, 6)

(6,1) (6,2), (6, 3), (6,4), (6, 5), (6, 6)

The total number of outcomes are 36.

The outcomes in which  first number is greater than the second number is 15.

Probability = Number of Favorable Outcomes / Total Number of Outcomes

Probability = 15 / 36

=5/12

Hence, 5/12 is the  theoretical fractional probability that the first number is greater than the second number.

Answer:

8b

Step-by-step explanation:

You can factor the b-term out since b-term exists for all terms in the expression. By factoring out, you are basically dividing the factored term off and put it outside of the bracket, thus:

\(\displaystyle{16b-8b=\left(16-8\right)b}\)

Then evaluate and simplify:

\(\displaystyle{\left(16-8\right)b=8\cdot b}\\\\\displaystyle{=8b}\)

Answer:

Gershon walked 620 mile

Step-by-step explanation:

From the question,

Gershon lives 310 mile from the soccer fields,

This means the distance from where Gershon lives to the soccer fields is 310 mile.

Likewise, the distance from the soccer fields to where Gershon lives his as well 310 mile.

So, if Gershon walks from his home to the soccer fields, he will cover a distance of 310 mile.

Then, if Gershon walks back home from the soccer fields, he will cover another distance of 310 mile.

Now, To determine how many miles he walked,

Total number of miles Gershon walked = The distance from where Gershon lives to the soccer fields + The distance from the soccer fields to where Gershon lives

Hence, Total number of miles Gershon walked = 310 mile + 310 mile

Total number of miles Gershon walked = 620 mile

Hence, Gershon walked 620 mile

The invested money will be doubled in a time of 9 years at an 8% Annual Percentage Yield (APY).

We arrive at the answer to this question by two methods, using the concept of Compound Interest.

Compound Interest, contrary to Simple Interest is calculated on the amount obtained every year, or the specified frequency of time. This means we end up with a larger amount than when the interest is yielded only on the original principal.

To calculate the total value of the investment (A) obtained for a given Principal (P) for a time of 'a' years, at a yield of 'r' rate of interest per xth frequency year, we use the following equation:

A = P(1 + r/x)ᵃˣ

In the given case, Invested Principal = $10,000

                              Rate of interest = 8% per annum = 0.08

                              Amount  = $20,000   (double the principal)

Thus, the time taken for the above growth will be:

20,000 = 10,000(1 + 8/100)ᵃ

20000/10000 = (1.08)ᵃ

2 = (1.08)ᵃ

a = log(2) to the base 1.08

a = ln(2)/ln(1.08)

a = 9.006 ≅ 9 years.

Thus, after about 9 years, the principal amount will be doubled.

Method 2:

We can use another trick to find the time taken, which is known as the Rule of 72.

According to this rule, the time taken for a principal to get doubled at an interest rate 'r' in APY is:

T = 72/r

Here, we get:

T = 72/8 = 9 years.

Note: Though this is a handy trick, it might not provide an accurate answer for higher values of T. It's better to check with the compound interest formula always.

We conclude that z-score = 0.0005 which is less than 5%.

To calculate the z-statistic,

We must first calculate the standard error.

Standard error is standard deviation divided by the square root of the population.

\(standard error=\frac{standard deviation }{\sqrt{population} }\)

In this case, it is equal to 1.81.

The z-score is defined the distance from the sample to the population mean in units of standard error.

z = (26 – 20)/1.81 = 3.31

Therefore we conclude that  z-score = 0.0005 which is less than 5%.

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. An example of a quadrilateral with equal and parallel opposite sides is a rectangle. It is a four-sided polygon with four 90-degree angles. The form of a rectangle is two dimensional.

Both of the rectangle's diagonals are the same length.

To make a decision for the hypothesis test, we need to analyze the ANOVA summary table for the test of significance of the overall regression model.

From the table, we can see that the regression sum of squares (SS) is given as 20, and the residual sum of squares (SS) is given as 400. We also know that the total sum of squares (SS) is the sum of the regression SS and the residual SS.

Since the degrees of freedom (df) for the regression model is equal to the number of predictor variables (k) minus 1 (k - 1), and the df for the residual is the total sample size (n) minus the number of predictor variables (k), we can calculate the df for the regression and the residual.

Given that the sample size (n) is 45 and the number of predictor variables (k) is 4, we can calculate:

df for regression = k - 1 = 4 - 1 = 3

df for residual = n - k = 45 - 4 = 41

Next, we need to calculate the mean square (MS) for the regression and the residual by dividing the SS by their respective degrees of freedom.

MS for regression = SS for regression / df for regression = 20 / 3

MS for residual = SS for residual / df for residual = 400 / 41

Finally, we can calculate the F-statistic by dividing the MS for regression by the MS for residual.

F = (MS for regression) / (MS for residual)

Now, we can compare the calculated F-statistic to the critical F-value at the given significance level (α = 0.05). If the calculated F-statistic is greater than the critical F-value, we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

Without the information of the critical F-value or the calculated F-statistic, we cannot make a definitive decision or final conclusion for the hypothesis test. Please provide the necessary values, and I will be able to help you with the decision and conclusion.

all the new articles are simply added to that to get the total number of published articles.

every months produces 12 more articles.

Step-by-step explanation:

To evaluate the integral Jx e^5x2 dx by making the substitution u = 5x^2, we need to first find the value of dx in terms of du. Taking the derivative of u with respect to x, we get du/dx = 10x, which can be rearranged to dx = du/10x.
Substituting this into the integral, we get:
Jx e^5x2 dx = J(u/10)e^u (du/10x)
Simplifying this expression, we get:
Jx e^5x2 dx = (1/10)Jue^u du
To evaluate this new integral, we can use integration by parts, with u = u and dv/dx = e^u. This gives us:
Jx e^5x2 dx = (1/10)(ue^u - J e^u du) + C
Resubstituting for u, we get:
Jx e^5x2 dx = (1/10)(5x^2e^5x^2 - Jx e^5x^2 dx) + C
Simplifying and rearranging, we get:
Jx e^5x2 dx = (1/20)x e^5x^2 + C
