Find the slope of the line on the graph. Write your answer as a fraction or a whole number, not mixed number or decimal.
Vesna [10]

Answer:

<em>The slope is:</em>

m=-\frac{3}{2}

Step-by-step explanation:

The slope m of a line is calculated using the following formula

m=\frac{y_2-y_1}{x_2-x_1}

Where the points (x_1, y_1) and (x_2, y_2)  are two points belonging to the straight line

Notice in the graph that the line passes through the points

(0, 2) and (2, -1)

Then the slope is:

m=\frac{-1-2}{2-0}

m=\frac{-3}{2}

Or the past 100 years, the average high temperature on october 1 is 78° with a standard deviation of 5°. what is the probability
valina [46]

Answer:

The probability is 0.683

Step-by-step explanation:

To calculate this, we shall be needing to calculate the z-scores of both temperatures

mathematically;

z-score = (x-mean)/SD

From the question mean = 78 and SD = 5

For 73

z-score = (73-78)/5 = -5/5 = -1

For 83

z-score = (83-78)/5 = 5/5 = 1

So the probability we want to calculate is within the following range of z-scores;

P(-1 <z <1 )

Mathematically, this is same as ;

P(z<1) - P(z<-1)

Using the normal distribution table;

P(-1<z<1) = 0.68269 which is approximately 0.683
