Liula [17]

Answer:

D

Step-by-step explanation:

complementary angle of 30°=60°

5n+20=60

Determine if the following probability experiment represents a binomial experiment. If​ not, explain why. If the probability exp
blondinia [14]

Answer:

C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.

Step-by-step explanation:

Given that an experimental drug is administered to 90 randomly selected​ individuals, with the number of individuals responding favorably recorded.

We find here the no of trials are 90 but we cannot say the probability is the same for all trials.

In other words, each individual may have a different probability to respond.

Since p , the success for each trial may differ for each trial binomial cannot be accepted

C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.

Please help me with this I need it bad
lana66690 [7]

Answer:

1

Step-by-step explanation:

The average rate of change is the gradient _

Gradient = Rise / Run = (y2 - y1) / (x2 - x1)

From the table ;

x2 = 4 ; x1 = - 1 ; y2 = 5 ; y1 = 0

Gradient = (y2 - y1) / (x2 - x1) = (5-0) / (4 - - 1) = 5/5 = 1

Find an equation for the line that passes through the point P(-5,-3) and is parallel to the line
Aneli [31]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{y = -1.75x - 11.75}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{Goes through (-5, -3) and parallel to 7x + 4y = 10}

Find:  \textsf{The equation in slope-intercept form}

Solution: We need to first solve for y in the equation that was provided so we can determine the slope.  Then we plug in the values into the point-slope form, distribute, simplify, and solve for y to get our final equation.

<u>Subtract 7x from both sides</u>

  • \textsf{7x - 7x + 4y = 10 - 7x}
  • \textsf{4y = 10 - 7x}

<u>Divide both sides by 4</u>

  • \textsf{4y/4 = (10 - 7x)/4}
  • \textsf{y = (10 - 7x)/4}
  • \textsf{y = 10/4 - 7x/4}
  • \textsf{y = 2.5 - 1.75x}

<u>Plug in the values</u>

  • \textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}
  • \textsf{y - (-3) = -1.75(x - (-5))}

<u>Simplify and distribute</u>

  • \textsf{y + 3 = -1.75(x + 5)}
  • \textsf{y + 3 = (-1.75 * x) + (-1.75 * 5)}
  • \textsf{y + 3 = -1.75x - 8.75}

<u>Subtract 3 from both sides</u>

  • \textsf{y + 3 - 3 = -1.75x - 8.75 - 3}
  • \textsf{y = -1.75x - 8.75 - 3}
  • \textsf{y = -1.75x - 11.75}

Therefore, the final equation in slope-intercept form that follows the information that was provided is y = -1.75x - 11.75
