What is an equation of the line that passes through the point (8,0)(8,0) and is parallel to the line x+y=5x+y=5?.

4s2 4p1 - electronic configuration corresponds to gallium

Periodic table has 4 different blocks, which are s block, d block, p block, and f block. Each block has corresponding elements which gives its electron configuration

What is group and period?

Prediction of Period ⟶ In electronic configuration of an atom, principal quantum number (n) of valence electrons represents the period of an element.

Prediction of Block ⟶ The orbital out of s,p,d and f which receives last electron represents block of an element

Prediction of Group ⟶ The group prediction occurs with help of block as:-

(1) For s block: Group Number = Number of valence e-

(2) For d block: Group Number = Number of e- in (n−1)d subshell + number of e- in ns subshell

(3) For p block: Group Number = Number of valence

e- + 10

(4) For f-block: Group Number = 3

Lets take an ex of chlorine ( Z= 17 )

Electronic configuration = 1s2 2s2 2p6 3s2 3p5

Since the last e- enters in p - subshell:

(i) Therefore Block will be "p "

(ii) For group we have element in p-block

∴ Group number = 10 + Valence e- in s subshell + Valence e- in p subshell

Group Number = 10+2+5=17

(iii) For period

Quantum number of valence e- =3

∴ Period number = 3

The equation of the line is y = 7x + 6 when  the line crooses the y-axis at the point (0,6) and has a slope of 7

The line crosses the y-axis at the point (0,6)

The slope of the line is 7

The equation of a line in slope point form is

y - y' = m(x - x')

Where m stands for the slope of the line and x' y' are the coordinates of the point through which the line passes.

So, the point x',y' is 0, 6 and the slope m is 7

y - y' = m(x - x')

y - 6 = 7 (x - 0)

y - 6 = 7x

y = 7x + 6

Therefore, the equation of the line which  crosses the y-axis at the point (0,6) and has a slope of 7 is y = 7x + 6

The inequality that represents the number of quarters in the jar is [tex]y \geq 24[/tex].

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Tyler filled a little container with quarters and dimes and gave it to his school's foundation club. The club party getting the container inquired, "Do you end up realizing how much is in the container?" Tyler said, "I know it's something like $8.50, yet I don't have a clue about the specific sum."

Let x be the number of dimes and y be the number of quarters. Then the inequality is given as,

0.10x + 0.25y ≤ 8.50

The inequality that represents the relationship will be 0.10x + 0.25y ≤ 8.50.

The inequality that represents the number of quarters in the jar, can be get by solving the above inequality for y, 0.10x + 0.25y ≤ 8.50.  can be written as [tex]y \geq \frac{8.5 - 2.5}{0.25}[/tex]  or  [tex]y \geq \frac{8.5}{0.25}[/tex]  or [tex]y \geq 24[/tex] .

The ladder is 26ft far up to the wall if the bottom of a 10-foot ladder is 2 ft closer to the wall.

A unit of length is any arbitrarily defined and agreed reference standard for measuring length.

The measurement or extent of something from end to end is defined as its length. In other words, it is the larger of two or the highest of three geometrical shapes or objects' dimensions. A rectangle, for example, has length and width dimensions.

Possibility is referred to as probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment.

The total amount owed after 3 years with the given rate of interest compounded quarterly will be $2851.52.

Compound interest is applicable when there will be a change in principal amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

Given that,

Principle amount P = $2000

Rate of interest R = 12%

Compounded quarterly n = 4

Time period T = 3 years

Total amount = P{1 + R/n]^(nT)

Total amount = 2000[1 + 0.12/4]^(4×3)

Total amount = $2851.52

Hence "The total amount owed after 3 years with the given rate of interest compounded quarterly will be $2851.52".

It will take Chad 12 hours to drive 672 miles and he will need 24 gallons of gasoline

Given that: Chad is planning a 672–mile road trip

Chad’s car can travel 308 miles with 11 gallons of gas. We can use this information to calculate the miles 1 gallon can cover. Thus:

Number of miles per gallon =   308/11 = 28 miles per gallon

Also, Chad plans to drive 168 miles every 3 hours. We can use this information to calculate Chad's speed. Thus:

Speed = 168/3 =  56 miles per hour

To determine how many hours it will take Chad to drive 672 miles:

Speed = distance/time

=> time = distance/speed    

Speed = 56 miles per hour and distance =  672 miles

time = 672/56 = 12 hours

Number of gallons = distance / Number of miles per gallon

Number of gallons = 672/28 = 24 gallons

residuals vs. the fitted values

We find a circular pattern where the errors are concentrated based on the residuals vs. the fitted values. indicating a breach of the assumption of equal variance (homoscedasticity). There is another nonlinear pattern that should be investigated.

Residuals vs. Order of collection

: Because the residuals are randomly distributed, the assumption of equal variance of the residuals is not violated.

Residuals vs. gestational length

A The gear concentration of the residuals in the shape of an oval indicate additional signals from the data that have not been modelled. As a result, the assumption of equal variance of the residuals is violated, and it may also indicate a nonlinear relationship between the dependent and independent variables. This problem can be solved by taking the log of the independent variable and normalising the data.

Parity vs. residuals

Because this is a binary variable, the plot provides no clear indication.

Residuals vs. mother's height

There is a clear oval pattern visible, indicating that the variable is violated.

Residuals vs. mother's weight

There is a clear oval pattern visible, indicating that the variable is violated.

Smoking vs. Residuals

Because this is a binary variable, the plot provides no clear indication.

Overall, this is the next step. We must examine the variables for multicollinearity. Because the residuals histogram is normally distributed, but the residuals vs fitted values has a violation.
