Answer:

The equation of the line is y=1.4x+6.8

Step-by-step explanation:

Given 2 points on the graph, you can find the slope using the equation: m=\frac{y2-x2}{y1-x1} . The 2 points are (-7, -3) and (-2, 4). X1 is -7, X2 is -2, Y1 is -3, Y2 is 4. The slope would be 1.4 once you plug in the numbers to the equation to finding the slope. Once you find the slope, use one of the points to find the y-intercept along with the slope you found and the y-intercept will be 6.8.

Math. Help much appreciated
ella [17]

First of all, expand the left hand side:

4x+4 - 7 < 3x + 5

Sum like terms:

4x -3 < 3x + 5

Add 3 to both sides:

4x < 3x + 8

Subtract 3x from both sides:

x < 8

So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.

Assume that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p. use the
mamaluj [8]

A binomial distribution is an experiment where there are two outcomes; Success and failure. For instance, you are given n = 128 and p = 0.27. The formula for the variance of a binomial distribution is n*p(1 – p) or n*p*q*. They are equivalent because q = 1- p. We will use the first equation.

 

Variance = n*p*(1 – p)

Variance = 128*0.27*(1 – 0.27)

Variance = 25.23

 

To get the standard deviation, find the square root of the variance.

Standard deviation = sqrt (Variance)

Standard deviation = sqrt (25.23)

<span>Standard deviation = 5.02</span>
