Mathematics
1 answer:
natita [175]3 years ago

Answer:

A

Step-by-step explanation:

Because B and D were both according to the Mean, and that is the same in the table so we can cross those out. And C is wrong because there are not less of a variation but more variation. So A would be your answer!

Hope this helps!

Find the slope of the line that passes through (95, 2) and (-2, 95).
adoni [48]

Answer:

Slope is -93/97

Step-by-step explanation:

To find slope subtract the y's and put that answer in top of a fraction. Then subtract the x's and put that on the bottom of the fraction. If its a smaller number on top and bigger number on the bottom, that is a proper fraction. If the bigger number is on top then it is an improper fraction. If it divides evenly, then the answer will just be a whole number (what the questions calls an integer) All these answers can be positive or negative.

***BUT, you have to start the subtractions with the same point!!!

Let's start with (-2, 95) in front, for both subtractions. (But it could be either point, the answer comes out the same)

Subtract y's: 95-2 is 93.

Subtract x's: -2 - 95 is -97

The slope is 93/-97 it is a proper fraction.

We can put the negative sign in front instead of at the bottom, it looks better.(and is the same)

Slope is -93/97

Suppose the current cost of gasoline is
Elodia [21]

Answer:

The current price index number is $604.2.

Step-by-step explanation:

The index value is the ratio between the current value and the reference value, multiplied by 100.

In this problem, we have that:

Current value = $3.48

Reference value: $0.576

Index price = (3.48/0.576)*100 = $604.2.

The current price index number is $604.2.

What is the value of k such that 5x-2y=9 and 6x+ky=4 are perpendicular?
max2010maxim [7]

15

5x-2y=9......(1)

6x+ky=4......(2)

slope of eqn i= -5/-2

=5/2

slope of eqn ii = -6/k

since the line are perpendicular

5/2 * -6/k = -1

-30= -2k

k=15
