You would subtract y on both sides so z-y then you get x=x. I think I hope this helps.

Answer:

a) The slope of the function is 3.

c) The equation is represented by n(t) = 3\cdot t + 35.

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

n(t) = m\cdot t + n_{o} (1)

Where:

m - Slope, measured in number of pieces per minute.

t - Time, measured in minutes.

n_{o} - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

n - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that n(15\,min) = 80\,p and n(45\,min) = 170\,p, then the following system of linear equations is formed:

15\cdot m + n_{o} = 80 (2)

45\cdot m + n_{o} = 170 (3)

The solution of the system of equations is:

m = 3 and n_{o} = 35

The slope of the function is 3.

c) By (1) and using results from a) we conclude that the equation function is:

n(t) = 3\cdot t + 35 (4)

d) The y-intercept of the function is 35.

The equation is 76*120/3.

76*120/3
9,120/3
3,040

The car will travel 3,040 yards in 120 seconds at that speed.

Is 0.000061 greater than 610,000<br>​
NeTakaya

Answer:

no.

Step-by-step explanation:

0.000061 is a decimal, and the number to the left of the decimal would be a whole number, which is 0. this means the number is less than one.. while 610,000 is a number jn the thousands, making it greater.

Jason and Yolanda both drew a simple random sample from a non-normally distributed population of 25,000. Jason’s sample consiste
UkoKoshka [18]

Answer:  Last Option is correct.

Step-by-step explanation:

Since we have given that

Total number of population = 25000

Percent of sample of Jason = 0.24%

Percent of sample of Yolanda's = 0.32%

So, Number of population according to Jason's sample is given by

\frac{0.24}{100}\times 25000\\\\=0.0024\times 25000\\\\=60

Number of population according to Yolanda's sample is given by

\frac{0.32}{100}\times 25000\\\\=0.0032\times 25000\\\\=80

Both the sample can be used to make inferences about the population

Hence, Last Option is correct.
