Answer:

slope = -2

Step-by-step explanation:

suppose,

(x₁,y₁)=(-1,-7)

(x₂,y₂)=(-2 ,-5)

slope (m)=?

now,

m=rise/run

   =Δy/Δx

    =(y₂-y₁)/(x₂-x₁)

    ={-5-(-7}/{-2-(-1)}  

     ={-5+7} / {-2+1}                 [negative plus negative =positive]

     =2/-1

     =-2

Answer:

Average rate of change = $11250 per year.

Step-by-step explanation:

Let's take two points from given information (2006, 90000) and (2010, 135000).

Now, use slope formula to find slope.

Slope =\frac{y2-y1}{x2-x1}

Use the two points to find average rate of change (slope)

Average rate of change =\frac{135000-90000}{2010-2006}

                                        =\frac{45000}{4}

                                       =11250

Average rate of change = $11250 per year.

gladu [14]
Use the std eqn of a circle with center at (h,k) and radius r:

(x-0)^2 + (y+2)^2 = 9^2, or just x^2 + (y+2)^2 = 9^2.

The meaning of significance. Asked to explain the meaning of "statistically significant at the α=0.05 level," a student says: "T
Irina18 [472]

Answer:

This explanation is not correct

Explanation:

Significance level is the probability that the null hypothesis rejected is in fact true. If we say there is a significance level of 0.10 or 10%(α=0.10 level) then there is a 10% chance of incorrectly rejecting the null hypothesis when there is actually no difference.

If we wish to reach a conclusion on rejection or acceptance of the null hypothesis, we could use the p value(the probability that observed results or more extremee results are true given null hypothesis)which we compare with the significance level to conclude. If the significance level is 0.10 and p value is 0.07(since p value is less than significance level) , we reject the null hypothesis and vice versa.
