question 12 I mark as brainliest ​

Answer:

y= -5x/2+17/2.... (x is between -5/2)

slope intercept= mx+b

y= -5x/2+17/2

Step-by-step explanation:

The equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .

The equation of line in the form of [tex]y = mx + b[/tex], is called slope intercept form of a line.

The equation of line from two points is given by

[tex]y -y_{1} = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } (x-x_{1} )[/tex]

According to the given question

We have two points (3,1) and (5, -4)

Therefore, the equation of line which passes through the points (3,1) and (5, -4) is given by

[tex](y -1)=\frac{-4-1}{5-3} (x-3)[/tex]

⇒[tex](y-1)=\frac{-5}{2}(x-3)[/tex]

⇒[tex]y -1=\frac{-5}{2}x+\frac{15}{2}[/tex]

⇒[tex]y =-\frac{5}{2} x+\frac{15}{2} +1[/tex]

⇒[tex]y = -\frac{5}{2}x+\frac{17}{2}[/tex]

Hence, the equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .

The supplementary angle pairs are: angles 4 and 5

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. Which means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

We know that Two Angles are Supplementary when they add up to 180 degrees.

In the given diagram , the pair of angles must be supplementary that are:

angles 1 and 8

angles 2 and 7

angles 4 and 5

angles 3 and 4

angles 1 and 2

angles 7 and 8

angles 3 and 6

 The  probability mass function is

         [tex]F(x) =  [ \left \ 8 } \atop {x}} \right. ] * p^x  *  q^{n - x }[/tex]

Step-by-step explanation:

From the question we are told that

   The maximum transmission time is  [tex]n  =  8[/tex]

Generally the number of times a packet is transmitted follows a binomial distribution given that the  the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p

Generally the probability mass function is mathematically represented as

          [tex]F(x) =  [ \left \ 8 } \atop {x}} \right. ] * p^x  *  q^{n - x }[/tex]

Here  x can take values x =  0 ,  1 , 2 , 3 , ... , 7

Answer:

Let's see what to do buddy...

Step-by-step explanation:

[tex]2x + 3y = 11[/tex]

Subtract the sides of the equation minus 2x :

[tex]3y = 11 - 2x[/tex]

Divided the sides of the equation by 3 :

[tex] \frac{3}{3}y = \frac{ - 2x + 11}{3} \\ \\ y = - \frac{2}{3}x + \frac{11}{3} [/tex]

Answer:

Step-by-step explanation:

They are being multiplied by 2 each time.

The value of the function is given by y = 2x

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

Let the x values be represented as x = { 1 , 2 , 4 , 8 , 16 }

Let the y values be represented as y = { 2 , 4 , 8 , 16 , 32 }

Now , the values of y are changing over the interval as

when multiplied by 2 , we get

2 = 2 x 1

4 = 2 x 2

8 = 2 x 4

16 = 2 x 8

32 = 2 x 16

Therefore , the values are multiplied by 2

Hence , the function is y = 2x

Step-by-step explanation:

If the swim team worked out for 8 hours last week, 6 of those hours were spent in the pool.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, In order to prepare for swim meets, the Red Ravens Swim Team practices for several hours each week. They practice in the water for three times as long as they practice in the gym.

Since the waiting time is three times as in pool times

Let "t" be the time in the pool during practice

thus, Waiting time =  3t

Also given,  the swim team practiced 8 hours total last week

So,

t + 3t = 8

t = 2

Thus, time spent in the pool = 3t = 3*2 = 6

therefore, If the swim team practiced 8 hours total last week, 6 hours they spend in the pool.

Answer:

[tex]\huge\boxed{\$1757.50}[/tex]

Step-by-step explanation:

In order to find a 5% discount off $1850, we have to realize 100% of something is the whole thing.

This means that a 5% discount makes the new cost [tex]100-5=95[/tex]% of the original.

To find 95% of a number, we can convert 95% into a decimal and multiply it by 1850.

When converting a percent to a decimal, we always divide the percent by 100.

[tex]95 \div 100 = 0.95[/tex]

We can now multiply 1850 by 0.95.

[tex]1850 \cdot 0.95 = 1757.50[/tex]

So the buyer only pats $1757.50.

Step-by-step explanation:

Answer:

For a given confidence level, t* is never smaller than z*.

Step-by-step explanation:

t* and z* are the critical value of a confidence interval.  For example, at 95% confidence, z* = 1.96.  This is because 95% of a normal curve is within ±1.96 standard deviations.

A student's t distribution has the same bell-curve shape as a normal distribution, but is shorter and wider, which is why t* is always larger than z*.  As the sample size increases to infinity, the distribution approaches normal.
