Answer 1
Let (x1,y1) be (2,10) and let (x2,y2) be (4,20). The formula for the slope of a line is

m=y2-y1/x2-x1

So letting y2=20, y1=10, x2=4 and x1=2, we get

m=20-10/4-2

m=10/2

m=5

So the slope of this line should be 5. Hope this helps! Mark as brainliest!

What is scatter plot Correlation ?

Scatter charts are similar to line charts in that they use horizontal and vertical axes to represent points of data. However, they have a very specific purpose. The scatterplot shows how much one variable is influenced by another. The relationship between two variables is called their correlation. There are three types of correlation: positive, negative, and none (no correlation).

Positive correlation: when one variable increases, the other also increases. ...

Negative correlation: an increase in one variable causes a decrease in the other variable. ...

No Correlation: nothing displayed

We have the following observations,

X Y

10 20

10 630

30 390

40 160

90 210

100 370

Now , we construct a scatter plot for the provide data. The constructed scatter plot is shown above. As we see in plot that there is no increase or decrease with increasing values of one variable .So, there is no correlation between two variables. Now, equation of the line that best fits the data, A best line of fit never connect all the points on the scatter plot. but it connects only a few points. There will have data points above and below the line. The equation of a line of best fit can be represented as y = mx+b y = m x + b , where m is the slope and b is the y-intercept.

here, y = - 0.3319 x + 312.16

Answers

At a time t hours after taking a tablet, the rate at which a drug is being eliminated is r(t) = 50(e^-0.1 t - e^-0.20 t) mg/hr. Assuming that all the drug is eventually eliminated, calculate the original dose. Enter the exact answer. The original dose was 0 mg.

A limit is a value that a function or sequence approaches as the input or index approaches a certain value. Limits are a fundamental concept in calculus, and they are used to define important ideas such as derivatives and integrals. They are also used in other areas of mathematics, such as real analysis and mathematical analysis.

The rate at which the drug is being eliminated is the derivative of the amount of drug present at time t. We can write this as:

r(t) = dA(t)/dt = 50(e^-0.1 t - e^-0.20 t) mg/hr

If we integrate both sides of this equation with respect to t, we get:

A(t) = ∫r(t) dt = ∫50(e^-0.1 t - e^-0.20 t) dt

This integral can be evaluated using integration by parts. Let u = e^-0.1 t and dv = e^-0.20 t. Then du = -0.1 e^-0.1 t and v = -1/(0.2) * e^-0.20 t = -5e^-0.20 t. We can then write:

A(t) = -5 ∫e^-0.1 t * e^-0.20 t dt + (1/0.2) ∫e^-0.1 t dt

The first integral on the right-hand side can be evaluated using the substitution y = -0.3t, which gives:

A(t) = -5 ∫e^y dy + (1/0.2) ∫e^-0.1 t dt

The first integral is simply -5e^y, and the second integral is -5e^-0.1 t. Substituting these results back into the expression for A(t) gives:

A(t) = -5(-5e^-0.3 t) + (1/0.2)(-5e^-0.1 t)

Combining constants and simplifying gives:

A(t) = 25e^-0.1 t - 25e^-0.3 t

We are told that all the drug is eventually eliminated, so A(t) approaches 0 as t approaches infinity. This means that the original dose A(0) must be equal to the limit of A(t) as t approaches 0.

Taking the limit as t approaches 0 gives:

A(0) = lim t → 0 [25e^-0.1 t - 25e^-0.3 t]

This limit is equal to 25 - 25 = 0, so the original dose was 0 mg.

Illegal trafficking of some items in a country was banned by its government in 2007. Is this supported by a majority, or a minority, of the population of the country? In a global poll conducted by an international agency for a reputed newspaper in January 2010 involving 900 residents of the country that asked whether the ban should stand or be repealed, 55% supported the banning.
(a) Find the standard error
(b) Find the test statistic
(c) Find the P-value, and interpret in context

Answers

a) The standard error is of: 0.0167.

b) The test statistic is of: 2.99.

c) The p-value is of 0.0013, representing the probability of finding a sample proportion of at least 55%.

What are the hypothesis tested?

At the null hypothesis, it is tested if there is not enough evidence that a majority of the population supports the measure, hence:

[tex]H_0: p \leq 0.5[/tex]

At the alternative hypothesis, it is tested if there is enough evidence that a majority of the population supports the measure, hence:

[tex]H_1: p > 0.5[/tex]

What is the test statistic?

The equation that defines the test statistic is given as follows:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.

The values of these parameters in this problem are given as follows:

[tex]p = 0.5, n = 900, \overline{p} = 0.55[/tex]

Then the standard error is calculated as follows:

Standard error = square root (0.5 x 0.5/900) = 0.0167.

Then the test statistic is calculated as follows:

z = (0.55 - 0.5)/0.0167 = 2.99.

What is the p-value?

We have a right-tailed test, as we are testing if the mean is different of a value, hence the p-value represents the probability of finding a sample proportion of at least 0.55.

Using a z-distribution calculator, with z = 2.99, the p-value is of:

0.0013.

In the case of the LL congruence theorem,

the two triangles have two pairs of equal sides (the legs) and one pair of equal angles (the right angles).

Therefore by the Side-Angle-Side (SAS) congruence criterion, the 2 triangles are congruent.

Answers

The probability of the cumulative distribution function  to meet the specification of the components is given by P( X = 0 ) = 0.0304 ,

P( X = 1 ) = 0.2892 , P( X = 2) = 0.6804.

As given in the question,

Let probability of the first component to meet the specification be P (M)

= 0.81

And probability of the second component to meet the specification be P (N)

= 0.84

Probability of the first component do not meet the specification be P ( M' )

= 1 - 0.81

= 0.19

Probability of second component do not meet the specification be P(N' )

= 1 - 0.84

= 0.16

X defined the number of components to the meet the specifications

Here X = 0, 1, 2

P( X = 0 ) represents components do not meet any specifications

= P( M' ∩ N' )

= P(M') P(N')   ( Independent )

= 0.19 × 0.16

= 0.0304

P( X= 1) represents components meet only one specification

= P( M∩N') ∪ P( M'∩N)

= P( M∩N') + P( M'∩N)

=  P(M) P(N')  +  P(M') P(N)  

= 0.81(0.16) + (0.19)(0.84)

= 0.1296 + 0.1596

P( X=2) represents components meet both the specification

= P( M ∩ N )

= P(M) P(N)

= 0.81(0.84)

= 0.6804

Therefore, the probability of the cumulative distribution function is given by P( X = 0 ) = 0.0304 , P( X = 1 ) = 0.2892 , P( X = 2) = 0.6804.

How to find the line of best fit?

A graph of the scatter plot and line of best fit is as shown in the attached file.

The temperature in this problem is the independent variable, or x.  This is due to the fact that we are assuming that the particular number of ice cream cones sold will depend on the temperature. Therefore, we can say that the number of ice cream cones will be the dependent variable, or y.

Therefore in our graphing calculator, we will enter temperature in the first list and then the number of cones in the second.

Sequel to drawing the scatter plot, we run the linear regression; we get the values for a and b in our equation, y = ax + b:

a = 5.08

b = 46.59

Therefore, the equation is;

y = 5.08x + 46.59.

Entering our temperature of 106 degrees, for x gives;

y = 5.08(106) + 46.59

Since 9 is directly after it, in the thousandths place, and it’s part of the numbers 5-9 which signify to round up, you have to round the 8 up to 9. So in the end, the rounded number would be 13.69

a clothing business finds there is a linear relationship between the number of shirts, n ,it can sell and the price, p , it can charge per shirt. in particular, historical data shows that 6000 shirts can be sold at a price of $55, while 8000 shirts can be sold at a price of $47. give a linear equation in the form p

Answers

The linear relationship between the number of shirts, n ,it can sell and the price, p is p = (-1/250)x + 79

The linear equation is

y = mx + b

Where m is the slope of the line

b is the y intercept

Here p is the total price

n is the number of shirts

The equation will be

p = mn + b

The price of 6000 shirts = $55

The price of 8000 shirts = $47

The slope of the line is the change in y coordinates with respect to the change in x coordinates of the line

The slope of the line = (47-55) / (8000-6000)

= -8/2000

= - 1/250

Substitute the point (6000, 55) in the equation

55 = (-1/250)(6000) +  b

55 = -24 + b

b = 55 + 24

b = 79

Substitute the values in the equation

p = (-1/250)x + 79

Therefore, the linear relation in the form of p is p = (-1/250)x + 79

Which equation has no solution?
0 14x-21=-6
012-x1=9
O 13x + 61 = 6
O 1-2x+81 = 0

Answers

Step-by-step explanation:

1 , 14x=-6+21

14x=15 , divide both sides by q4 to get the value of x

x=15/14

2 , x1=x

-x=9-12

-x=-3 , divide both side by -1

x=3

3, 13x=6_61

13x= 55 , divide both sides by 13

x=55/13

4, 1-2x+81=1+81_2x

82_2x=0

-2x=-82 , divide both sides by -2

x=41

So, all of them have a solution

The sequence  is f(n)=3[tex]n^{2}[/tex]−n.

What is sequence?

Sequences are ordered collections of numbers, often known as "terms," such as 2,5,8. There are some sequences that adhere to a particular pattern that allows for endless extension. For instance, 2,5,8 adheres to the "add 3" pattern, thus we may now continue the process. There are formulae for sequences that show us where to locate any given term.

We have 2 10 24 44 70 (which we refer to as the first column)

If we have 10 - 2 = 8, 24- 10 = 14, 44- 24 = 20, and 70- 44 = 26,

(this is second column)

The third column is now 14 - 8 = 6, 20 - 14 = 6, and 26 - 20 = 6.

First, create the second column sum formula.

Sum(x)

S(x)=8+6(x1)=6x+2 is the second digit of the phrase.

Next make the first column formula f(n)

f(n)= 2+[tex]sum_{n-1}[/tex]

=2+(n−1)[3(n−1)+5]

=2+(n−1)(3n−3+5)

=2+(n−1)(3n+2)

=2+3[tex]n^{2}[/tex]+2n−3n−2

=3[tex]n^{2}[/tex]−n

The sequence  is f(n)=3[tex]n^{2}[/tex]−n.
