The equations below could be used as a line of best fit to approximate the data in the scatterplot is y = 0.92x + 14.07

To find the equation of the line of best fit, we first need to plot the data points on a scatterplot. Here is a scatterplot of the given data:

To find the equation of the line of best fit, we need to find the slope (m) and y-intercept (b) of the line. One way to do this is to use the method of least squares, which involves finding the line that minimizes the sum of the squared distances between the line and each data point.

Using this method, we can find that the equation of the line of best fit for this data is:

y = 0.92x + 14.07

This means that for every increase of 1 unit in x, we can expect an increase of 0.92 units in y. The y-intercept of 14.07 means that when x is 0, we would expect y to be approximately 14.

As per the set theory, the number of student who take math course is 800

Set:

In math, set means an organized collection of objects and can be represented in set-builder form or roster form.

Given,

Here we know that suppose that all of the 1000 first-year students at a certain college are enrolled in a math or an English course. suppose 400 are taking both math and English and 600 are taking English.

Now, we need to find the number of students who take math course.

While looking into the given question we have identified that,

Total Number of students = 1000

Number of students in both course = 400

Number of students taking English = 600

Then the number of students who take math course is calculated as

=> 1000 - 600 + 400

=> 800

Therefore, the resulting number of students is 800.

Answer:

2.25c + 1.75p ≤ 28

1.25c + 2.125p ≤ 30

Step-by-step explanation:

Write a system of two inequalities to model loaves of bread and

cake that can be baked.

let

number of cornbread loaves = c

number of poppy-seed blueberry Cake loaves = p

corn bread

cups of flour = 2 1/4 = 2.25

teaspoon of baking soda = 1 1/4 = 1.25

One loaf of poppy-seed blueberry cake

cups of flour = 1 3/4 = 1.75

teaspoons of baking soda = 2 1/8 = 2.125

The bakery has 28 cups of flour and 30 teaspoons of baking soda in stock.

Quantity of flour to use

c(2.25) + p(1.75)

Quantity of baking soda to use

c(1.25) + p(2.125)

The inequality is

c(2.25) + p(1.75) ≤ 28

c(1.25) + p(2.125) ≤ 30

Alternatively,

2.25c + 1.75p ≤ 28

1.25c + 2.125p ≤ 30

Answer:

-3.8=n

Step-by-step explanation:

My goal is to get n all by itself, but its multiplied by 6. If I do the inverse operation (which is division) on both sides I will get -22.8/6=n. Now I can just simply combine the like terms and finalize my answer. 6 * 3=18 but -22.8 is a decimal number so my answer will range from around 3.5-3.9. if I divide -22.8/6 I get -3.8.

Step-by-step explanation:

The formula for the temperature in degrees Fahrenheit F in terms of the temperature in degrees Kelvin K is F = 9/5 (K-273)

What is temperature ?

Coldness and hotness is measured by temperature which is one of the fundamental units of measurements.

It is given that The temperature in degrees Kelvin is 273 degrees less than the temperature in degrees Celsius and generally the formula used for temperature conversion is given by :

\(\begin{aligned}\frac{C}{100}=\frac{F-32}{180}=\frac{K-273}{100}\end{aligned}\)

Now, converting Fahrenheit scale to celsius scale by comparing  Fahrenheit F and Kelvin K from above formula :

\(\begin{aligned}\frac{F-32}{180}&=\frac{K-273}{100}\\F&=\frac{9}{5}(K-273)\end{aligned}\)  

Therefore, the formula for the temperature in degrees Fahrenheit F in terms of the temperature in degrees Kelvin K is F = 9/5 (K-273)

Answer:

23.8 is the diameter.

Step-by-step explanation:

Answer:

\(\huge\boxed{Diameter=11cm}\)

Step-by-step explanation:

Important information:

Circumference of a circle= \(\pi*diameter\)

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

\(diameter=\frac{circumference}{\pi}\)

2) Divide 34.54 by 3.14(\(\pi\)).

\(34.54/3.14=11cm\)

There is a a circle whose circumference is 34.54 cm. Find the diameter of the circle. Remember use 3.14 for π.

- To know the diameter divide 34.54 cm by pi (π) to get the answer.

\( \large \tt d = \frac{34.54}{\pi} \\ \large \tt d = 11cm\)

Therefore, the diameter of the circle is 11cm

An equation is an expression that shows the relationship between two or more numbers and variables.

Lou's car had 4.6 gallons of gas in the 14-gallon tank. To fill the tank:

Amount of gas needed = 14 gallon - 4.6 gallon = 9.4 gallons

Lou filled the tank costing 3.50 per gallon, hence:

Total cost = $3.50 * 9.4 gallons = $32.90

d = 1/8t

where,

t = time

d = distance

which parameter 1/8 is indicating ?

The equation d = 1/8t describes a function that relates time (t) and distance (d) traveled.

The parameter 1/8 in the expression d = 1/8t is the rate of change of distance with respect to time.

It represents the amount of distance traveled in one unit of time.

In this case, 1/8 is the speed or velocity of the object being considered. It tells us that for every unit of time that passes, the distance traveled by the object increases by 1/8 units.

Answer:

363 feet = 11 seconds

Step-by-step explanation:

330 feet = 10 seconds

=> 330/10 feet = 10/10 seconds

=> 33 feet = 1 second

=> 33 × 11 feet = 11 × 1 second

=> 363 feet = 11 seconds.

Therefore, the Burj Khalifa can travel 363 feet in 11 seconds.

Answer:

\(363ft\)

Step-by-step explanation:

First we know that the elevator can travel 330 feet  in just 10 seconds. That's can be interpret as:

\(\frac{330ft}{10s} = \frac{33ft}{1s}\)

How you can see each second the elevator travel 33 feet so if you want to know how many travel in 11 second you only have to multiply by 11 the 33ft.

\(33ft \cdot 11s = 363ft\)

The diametric size of cell H is 3.86 times larger the diametric size of cell K.

How is a ratio determined?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. A ratio is a comparison or condensed version of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.

Given, the diametric size of cell H, say y = 3.52×10⁻³ cm
The diametric size of cell K, say x =  9.1×10⁻⁴ cm = 0.91×10⁻³ cm
The ratio of the diametric size of H to K, y/x = 3.52×10⁻³/0.91×10⁻³ = 3.86
Thus, y = 3.86x, the diametric size of cell H is 3.86 times the diametric size of cell K.
