The unit rate of change of Y with respect to X is the amount Y changes for a change of one unit in XThe table below represents a proportional relationship with a constant unit rate of change of Y with respect to X

Which describes a greater unit rate of change of Y with respect X, the equation y=0.25x or the table?

Choose 1 answer:
A. The table
B. The equation
C. The unit rates are the same
The unit rate of change of Y with respect to - 1

Answers

Answer 1
Answer:

By calculating the slope, we can say that the table best describes the change in Y with respect to X.

What is slope?

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Equation of line is y = mx + c where m is the slope.

Similarly, in y = 0.25x, 0.25 is the slope.

For the table, we need to calculate slope.

m = (y2 - y1)/(x2 - x1)

m = (0.8-0.4)/(2-1)

m = 0.4

As we compare, it is clear that the slope calculated from the table is greater.

give you 300 dollars if u get this right. you have my word The lifetimes of 20,000 light bulbs are normally distributed. The mean lifetime is 230 days. The standard deviation is 40 days. Find the values defined by the standard deviation in a normal distribution for 3 standard deviations.

Answers


Wow !  I didn't know the numbers when I read the question,
but with that much riding on it, I had to go look them up and
learn something.  You probably could have done the same thing
and saved yourself some money, but it's too late for that.  It's all
mine now, as soon as I finish writing this answer.  

In the normal distribution, 68.27% of the values lie within one
standard deviation of the mean, 95.45% lie within two standard
deviations, and 99.73% lie with three standard deviations.

Within one sigma:  68.27% of 20,000 = 13,654
13,654 light bulbs will last between 190 days and 270 days.

Within two sigma:  95.34% of 20,000 = 19,068 
19,068 light bulbs will last between 150 days and 310 days.


Here's the one you asked for:

Within three sigma:  99.73% of 20,000 = 19,946
19,946 light bulbs will last between 110 days and 350 days.

Only 54 light bulbs will burn out in less than 110 days
OR keep going more than 350 days. 

OK.  Now you owe me.

Answer:

9) x = 32

11) x = 33.3

Step-by-step explanation:

9) 1/4x = 8

4 x 1/4x = 8 x 4

X = 32

11) 3/5x = 20

5 x 3/5x = 20 x 5

3x = 100

3x ÷ 3 = 100 ÷ 3

X = 33.33333

X = 33.3
