ANSWER: Midline: is the horizontal line that passes exactly in the middle between the graphs maximum and minimum points.

Amplitude: is the vertical distance between the midline and one of the extremum points.

Period: is the distance between two consecutive maximum points or two consecutive minimum points (these distances must be equal). HOPE THIS HELPS!

roll the die twice. what is the probability of rolling a 6 on the 1st roll? an odd number on the 2nd roll?

Crank

The probability of rolling a 6 on the 1st roll is $\frac{1}{6}$ , since there is only 1 out of 6 sides of the dice that has six pips.

The probability of rolling an odd number is $\frac{1}{2}$ , since there are 3 out of 6 sides of the dice that has an odd number of pips. $\frac{3}{6} = \frac{1}{2}$

Then the probablity of both events happening one after another is $\frac{1}{12}$ . You have to multiply both probabilities of the events: $\frac{1}{6} * \frac{1}{2} = \frac{1}{12}$

Draw and write to explain how these two problems are different: 35-15=20 and 43-26=23

Verdich [7]

35-15=20 is correct. However, 43-26 does not equal 23, it equals 17.

Pls help me in this i really need help :( :)

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

First off, let's write the line in point-slope form:

$\rm \hookrightarrow (y-y_0)=m(x-x_0)$

(x₀, y₀) any random point on the line
'm' is the value of the slope

Let's calculate the slope:

$\rm \hookrightarrow Slope = \frac{y_2-y_1}{x_2-x_1}$

(x₁, y₁): any random point on the line ⇒ (-2, -6)
(x₂,y₂): any random point on the line that is not (x₁, y₁) ⇒ (2, -3)

$\rm \hookrightarrow slope = \frac{-3--6}{2--2} =\frac{3}{4}$

Now that we found the slope, let's put it into the point-slope form

⇒ we need (x₀, y₀) ⇒ let's use (2,-3)

$(y-(-3))=\frac{3}{4} (x-2)\\y+3=\frac{3}{4} (x-2)$

The equation, however, could also be put into 'slope-intercept form'

⇒ gotten by isolating the 'y' variable to the left

$y = \frac{3}{4}x-\frac{9}{2}$

Answer: $y = \frac{3}{4}x-\frac{9}{2}$ or $y+3=\frac{3}{4} (x-2)$

*Either equations work, put the one that you are the most familiar with

Hope that helps!

Determine whether each sample method is unbiased or biased. If the method is unbiased, use it to make a prediction. If the metho

The representative took a sample to estimate the proportion of customers that do not subscribe to movie channels.

He took a sample from the customer base and the sample proportion he gets is 22% (p = 0.22). This sample proportion is an unbiased estimator of the populations proportion, so we can use it to calculate how many customers do not subscribe to movie channels:

$n=N\cdot p=5240\cdot0.22\approx1153$

Answer: we can estimate that there are 1153 customers that do not subscribe to movie channels.
