If y=x-6 where changed to y=x+8 how would the graph of the new function compare with the first one ?

madreJ [45]

Answer:

The function $y=x+8$ is the function $y=x-6$ shifted 14 units up.

The graph of the first equation will be a line with slope 1 that intersects the y-axis at point (0,-6)

The graph of the second equation will be a line with slope 1 that intersects the y-axis at point (0,8)

Step-by-step explanation:

The equation of the line in slope intercept form is:

$y=mx+b$

Where m is the slope and b is the y-intercept.

The first equation is:

$y=x-6$

The second equation is:

$y=x+8$

The parent function with the form $y=mx$ can be shifted up or shifted down k units.

When $y=mx+k$ the function is shifted k units up.

When $y=mx-k$ the function is shifted k units down.

Then, the function $y=x+8$ is obtained by adding k=14 to the function $y=x-6$ .

Both equation has the same slope, but the y-intercepts are different.

The graph of the first equation will be a line with slope 1 that intersects the y-axis at point (0,-6)

The graph of the second equation will be a line with slope 1 that intersects the y-axis at point (0,8)

Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who

Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

Explanation:-

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-

when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be small, large but finite or infinite.

Example :- 1

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are finite number of observations.

Example :- 2

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

Population:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the population

The number of observations in the population is defined to be the size of the population.

Example :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

Sample:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population

A pioneer study randomly assigned pregnant women to either a daily multivitamin supplement (including folic acid) or a placebo.

Fittoniya [83]

Answer:

0.42

Step-by-step explanation:

The computation of the relative risk reduction is shown below:

= ((Number of congenital cases malformation recorded in 2052 - women taking placebo in 2052) - (number of congenital cases malformation recorded in 2104 - women taking placebo in 2104)) ÷ (Number of congenital cases malformation recorded in 2052 - women taking placebo in 2052)

= ((47 ÷ 2052) - (28 ÷ 2104)) ÷ (47 ÷ 2052)

= 0.42
