What is the slope of (-7,5) and (5,-1)

Mathematics
1 answer:
svlad2 [7]3 years ago
4 0

Answer:

-1/2

Step-by-step explanation:

Method 1)

Use the graph

You must go from point (-7, 5) to point (5, -1) by using only vertical and horizontal paths.

Start at point (-7, 5).

Go down 6 units. That means a rise of -6.

Now go right 12 units to point (5, 1)

That is a run of 12 units.

slope = rise/run = -6/12 = -1/2

Method 2)

Use the slope formula

slope = (y2 - y1)/(x2 - x1) = [5 - (1)]/(-7 - 5) = (5 + 1)/(-12) = 6/(-12) = -1/2

vichka [17]

Answer:

Part 1) The explanatory variable is the type of oven

It is a categorical variable

Part 2) The response variable is the baking time

It is a quantitative variable

part 3) two-sample z-test for proportions should be used for the test

Step-by-step explanation:

An explanatory variable is an independent variable that is not affected by all other variables. In this experiment, the type of oven is the input variable and it  is not affected by any other variable

A categorical variable is one that has two or more categories without any intrinsic ordering of the categories. The type of oven is either gas or electric, so it is categorical.

A response variable is a dependent variable whose variation depends on other variables. The baking time in this experiment depends on the type of oven used

A quantitative variable is one that take on numerical values.

A two proportion z-test allows you to compare two proportions to see if they are the same. The null hypothesis (H0) for the test is that the proportions are the same. The alternate hypothesis (H1) is that the proportions are not the same.

Alex invests his money in an account paying 2% interest compounded semiannually. What is the effective annual yield on this acco
Travka [436]

Answer: 2.01%.

Step-by-step explanation:

Suppose Alex invests $1 into the account for one year. The formula is A=P0⋅(1+rk)N⋅k with P0=$1. We know that r=0.02 and k=2 compounding periods per year. Now, N=1 year. Substituting the values we have A=$1⋅(1+0.022)2=$1.0201. Now, to calculate the effective annual yield, we will use the formula rEFF=A−P0P0. rEFF=1.0201−11=0.0201 or 2.01%. When rounded to two decimals, rEFF=2.01%. However, do not include the % in your answer.
