20%(20 percent) of the people  are 25 or older according to the line plot that shows the ages of people taking a driving test at a certain station one day.

Percentage signifies a fraction of a total amount and means "per 100." For instance, 45% denotes 45 out of 100. Finding the percentage of a whole in terms of 100 is what percentage calculations are all about. It can be computed manually or with the use of internet calculators.

A % is a relative figure that represents one tenth of a quantity. One percent is a hundredth part; consequently, 100 percent denotes the complete amount and 200 percent specifies twice the supplied number. percentage

The word "percent" comes from the Latin per centum, which means "hundred" or "by the hundredth.

The total number of people we have are 25

From the line plot given, we see that fived people are 25, or older

Then,

5 / 25

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

A closed circuit is required to carry current. If there is a break anywhere in the path, the circuit will open and no current will flow, and the metal atoms in the wire will quickly become peaceful and electrically neutral.

Current flows in a closed circuit, but electrons are left behind in an open circuit.

Imagine a gallon of water flowing through an open pipe. Water flows for a short time, but stops when all the water comes out of the pipe. If you pump water into a closed system of pipes, it will continue to flow as long as you force it to move.

Closed circuit design:

breaks are often created by design. For example, a simple light switch opens or closes the circuit that connects the light to the power source. When building a circuit, it is recommended that the battery or other power source be disconnected when the circuit is not in use. Technically, this creates an open circuit. The

extinguished flashlight is an open circuit. In the flashlight shown here, the flat black button on the bottom left controls the internal switch. A switch is nothing more than two flexible metal strips in close proximity to each other. Push the black button all the way to the right to open the switch and turn off the flashlight. The switch in the open position disconnects the bulb from the battery, creating an open circuit.So, for the light bulb in a circuit turn on when the switch is closed.

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.

The correct notation for the 8th term of the expansion (3x – 5)12 would be (3x)^(-5)8.

The term "expansion" describes the process of expanding or expanding. It can be used to describe actual expansion, such as when an organism gets bigger or a gas expands to fill a container. It can also relate to abstract notions such as the development of thoughts or knowledge. Extension in economics refers to growth in the size of the economy or in a specific sector of the economy, such as a rise in goods and services output. The process of conquering or occupying additional areas, such as when a nation extends its borders by conquest or settlement, is another definition of expansion. The act of growing larger or more extensive is generally referred to as expansion.

How to solve?

The model assumption are satisfied in histogram, residuals vs order of collection and residuals vs fitted values.

HIstogram

We can see from the histogram that the residuals are normally distributed, so the assumption that the errors are normally distributed is met.

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.

We must determine whether the independent variables are correlated with one another. If they are correlated, we must discard the one that is least correlated with the target variable.

The minimum score required for recruitment is 669

The normal distribution is expressed as

z = (x - µ)/σ

Where

x = SAT Mathematics scores.

µ = mean score

σ = standard deviation

From the question, we have

µ = 518

σ = 113

The probability value for the top 9% would be (1 - 9/100) = (1 - 0.09) = 0.91

the z score corresponding to the probability value is 1.34

1.34 = (x - 518)/113

1.34 × 113 = x - 518

151.42 = x - 518

x = 151.42 + 518

x = 669 to the nearest whole number.

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
