Answer:

y=3x-1

Step-by-step explanation:

you first find the gradient

(-7,-5). (-7,-2)

x¹ y¹ x² y²

gradient=y²-y¹

x²-x¹

-2+5

-7+7

3/1=3. gradient is 3

equation formula= y=mx+c

(among the two sets of value you were given use one eg I will use -7 and -2)

y-(-7)/x-(-2)=3

y+7/x+2=3

y+7=3(x+2)

y+7=3x+6

y=3x+6-7

y=3x-1

Note: See the attached files for the tables and answers to questions 2, 3, 4 and 5.

Answer:

Step-by-step explanation:

Let x be the random variable representing the SAT scores for the students at a local high school. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 1527

σ = 291

the probability to be determined is expressed as P(x > 1207)

P(x > 1207) = 1 - P(x ≤ 1207)

For x < 1208

z = (1207 - 1527)/291 = - 1.1

Looking at the normal distribution table, the probability corresponding to the z score is 0.16

P(x > 1207) = 1 - 0.16 = 0.84

Therefore, the percentage of students from this school earn scores that satisfy the admission requirement is

0.84 × 100 = 84%

The simplified expression is 1/4x²  

Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x²-5x+11

Given here, the expression is (20x⁻³ / 10x⁻¹)⁻² =2⁻²× x⁻²

                                                                             = 1/4x²

Hello!

I didn't find the exact box plot for this exercise but I've found one that'll help you identify the required values

When constructing a box plot the box lower and upper limits are defined by the first and third quartiles and the line separating it in two represents the median.

In this case, the box is lying on the side, the first quartile is represented by the left side of the box. If you see the graphic this one corresponds to 25.

The median, as said, is represented by the line drawn inside the box, it is not necessarily in its middle but it will always be inside it.

Watching the example, the median is 33

Answer:

The quarterly growth rate in revenues is significantly different from 1.2%.

b. 2,666,858

Step-by-step explanation:

Given that:

The regression equation can be represented as :

[tex]log_{10} \hat Y= 6.102+0.012 X - 0.129 Q_1 - 0.054 Q_2 + 0.098 Q_3[/tex]

In testing the significance of the coefficient of X in the regression equation (0.012) which has a p-value of 0.02.

The null and alternative hypothesis can be stated as;

[tex]H_0:[/tex]    The quarterly growth rate in revenues is not significantly different from 1.2%.

[tex]H_a:[/tex]   The quarterly growth rate in revenues is significantly different from 1.2%.

The decision rule is to reject the null hypothesis if the p-value is less than 0.05.

From above ; the p-value = 0.02 which is less than 0.05.

Conclusion:

Thus; we reject the null hypothesis and accept the alternative hypothesis. i.e

The quarterly growth rate in revenues is significantly different from 1.2%.

b.

Are there any choices?..

The correct statement the describes the equation is The lines intersect at (1, 0) and the lines are parallel.

x - y = 1.............equation 1

y - x = 1.............equation 2

Add equations (1) and (2):

(x - y) + (y - x) = 1 + 1

Simplifying

0 = 2

Since 0 = 2, the system is inconsistent, meaning there is no solution. The lines represented by the equations are parallel and will never intersect.

Answer:

a. All measures exist

b. The Mean and the mode

c. Positively skewed

d. The mean and the median

Step-by-step explanation:

a. The frequencies of the data are;

1       2

2      4

3       1

5       2

6       3

9        1

11        1

14        1

15       1

18       1

The formula for mode is given as follows;

The mean = 108/17 = 6.35

The median of 1 1 2 2 2 2 3 5 5 6 6 6 9 11 14 15 18 = (n + 1)/2th term = 9th term  

∴ The median = 5

The mode = 3×Median - 2 × Mean = 15 - 2 × 6.35 = 2.29

Hence all exist

The answer is none theses measures

b. Whereby 18 is replaced by 39 the mean will be then be

(108 + 39 - 18)/17 = 7.59

The median, which is the 9th term remain the same;

Hence only the mean and mode will be affected

c. Since more values are concentrated on the left side of the data distribution, the distribution is positively skewed

d. The largest measurement = 18 the 17th term

Removal will give

Mean = (108 - 18)/16 = 5.625 Mean changes

Median = (16 + 1)/2 th term = 8.5th term = 5 The median remains the same

The mode = 3(Mean - Median) changes

Therefore, the mean and the median will be changed.

The objective here is to create a journal entry for the Star corporation treasure stock transaction, then find the total amount of Paid-in Capital from Treasury Stock at December 31, 2017.

Journal Entries:

Date                  Description                          $                      $

Mar 1                Treasury Stock                   40,000  

Cash                                                                                   40,000

June 1               Cash(1,000*12)                     12,000  

                       Treasury Stock(1,000*8)                               8,000

                        Paid in Capital(12-8)*1,000                           4,000

Sept 1                Cash(1,000*10)                       10,000  

                      Treasury Stock (1,000*8)                               8,000

                      Paid in Capital (12-10)*1,000                          2,000

Dec 1               Cash (1,000*7)                             7,000  

                     Paid in Capital (8-7)*1,000             1,000  

                     Treasury Stock (1,000*8)                                 8,000

The Beginning Balance:

Treasury Stock Price = 250,000 / 5,000

= $50

Paid in Capital = [2,000×(53-50) + 2,000×(48-50) + 1,000×(43-50)]

= [(2,000×3) + (2,000×-2) + (1,000×-7)]

= 6,000 - 4,000 - 7,000

= -5,000

During the year transactions = 4,000+2,000-1,000

= $5,000

The total amount paid in Capital = Beginning Balance + During the year transactions  

= -5,000 + 5,000

= 0

Some other circumstances under which company can go for the purchase of treasury stock includes:

A situation where by they resells  the stock in the bid to increase funds for future investment.

The company can go for the purchase of treasury stock in order to empower the financial ratios and have full control interest in the company

It can also aid as a means of increasing the price of the share when it is underpriced in the market.

lowest score is 5.35531

highest score is x=5.45961

Step by step Explanation:

· A Z-score reffered to as a numerical measurement that identifies a value's relationship to the mean of a group of values. Z-score is usually measured in terms of standard deviations from the mean.

We were to Consider a value to be significantly low if its z score less than or equal to minus2 or consider a value to be significantly high if its z score is greater than or equal to 2

the z-score is given by:

z-score=(x-μ)/σ

where:

x=score

μ=mean=5.45961

σ=std deviation=0.05215

To calculate the lowest cost when the the z-score is -2, we have

[tex]-2=(x-5.45961)/0.05215[/tex]

To get the value of x then we collect like terms

-0.1043 = =(x-5.45961)

x=-0.1043 + 5.45961

[tex]X=5.35531[/tex]

therefore, the lowest score is 5.35531

Let us calculate the highest score when the z-score is 2 ,

then highest score will be:

[tex]2=(x-5.45961)/0.05215[/tex]

To get the value of x then we collect like terms

0.1043 = =(x-5.45961)

x=0.1043 + 5.45961

[tex]X=5.45961[/tex]

therefore the highest score is x=5.45961
