Researchers wanted to determine if there was an association between the level of trauma of an individual and their risk
of diabetes. The researchers studied 1544 people over the course of 12 years. During this 12-year period, they
interviewed the individuals and asked questions about their daily lives and the hassles they face. In addition,
hypothetical scenarios were presented to determine how each individual would handle the situation. These interviews
were videotaped and studied to assess the emotions of the individuals. The researchers also determined which
individuals in the study experienced any type of diabetes over the 12-year period. After their analysis, the researchers
concluded that the trauma-free individuals were less likely to experience diabetes. Complete parts (a) through (c).

The ordered pairs that solve the system of inequalities is given by:

(3, -2), (1, -1).

To verify if an ordered pair solves a system of inequalities, we have to verify if it respects all conditions.

For this problem, the conditions are given as follows:

For the ordered pair (0,3), we have that:

x - 3y  = -9 < 1, hence it does not respect.

For the ordered pair (-1,1), we have that:

-1 -3 = -4 < 1, hence it does not respect.

For the ordered pair (3,-2), we have that:

For the ordered pair (4,0), we have that:

For the ordered pair (2,3), we have that:

2 - 3(3) = -7 < 1, hence it does not respect.

For the ordered pair (1,-1), we have that:

He gained $330 of interest in the three months.

Here we will use the Simple interest formula

Simple Interest (SI) = Simple Interest (SI)

initial principal balance = P = 24000

annual interest rate = r = 5.5

time (in years) = t = 3 months out of 1 year

                            = 3/12 = 1/4

Lets substitute the values in the formula

Simple Interest (SI) = (P × R × T)/100

                                = (24000 × 5.5 × 1/4)/100

                                = 330

Simple interest is a quick and straightforward approach to figure out how much interest has accrued on a sum of money. Interest is always applied to the main sum, and there is a constant rate of interest applied during the course of the calculation.

Any bank where we deposit money pays us interest on the amount when we do so. There are other forms of interest charged by banks, but simple interest is one of them. To begin with, let's define a loan before delving further into the idea of simple interest.

By using the given graph, we can see that f(-5) = 3.

Here we have an image with the graph of the function y = f(x).

Remember that each point on that grid has the coordinates (x, y), where the values of x are on the horizontal axis, and the values of y are in the vertical axis.

So, if we want to find f(-5), then we want to see what value of y takes f(x) when x = -5.

So, first we need to go to the horizontal axis and find x = -5.

Once we find that value, now we need to move up or down along a vertical line (depending on where is the graph of the function). In this case we would move upwards. Now, count how many units we move up until we hit the graph of the function, that number of units will be the value of y.

In this case, we need to move 3 units upwards to hit the graph, then we have y = 3.

This means that the value of the function when x = -5 is y = 3, so we can write:

f(-5) = 3

Answer:

y = 3

Step-by-step explanation:

Points: (1, y), (-5, -1)

slope = (y_2 - y_1)/(x_2 - x_1)

slope = (-1 - y)/(-5 - 1) = (-1 - y)/(-6)

slope = 2/3

(-1 - y)/(-6) = 2/3

Multiply both sides by -6.

-1 - y = -6 × 2/3

-1 - y = -12/3

-1 - y = -4

-y = -3

By adding the number of cups needed for each cake, we conclude that you will need 25 cups of ingredients to make the 4 cakes.

We know that the recipe calls for:

That is for a single cake, so in a single cake you need a total of cups given by the sum of the above quantities, this gives:

(1 + 3/4) + (4 + 1/5) + 3/10 = (1 + 4) + (3/4 + 1/5 + 3/10)

= 5 + (3/4 + 2/10 + 3/10) = 5 + (3/4 + 5/10) = 5 + (3/4 + 1/2) = 5 + 5/4

= 5 + 4/4 + 1/4 = 6 + 1/4

Each cake needs (6 + 1/4) cups of ingredients, so 4 cakes will need:

4* (6 + 1/4) = 24 + 4/4 = 25

You will need 25 cups of ingredients to make the 4 cakes.

It tells you when you read the sentence carefully.

A) The reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

B) The reason why Susan had a higher retirement savings than bill is because Susan started investing 10 years earlier than bill and so her investment had a longer period to compound.

A) From the given exponential graph, we see that Chris curve was simialr to that of susan between ages 25 to 35 and suddenly Chris curve began to rise at a faster rate than that of Susan after that until when retired at 65 years of age.

Since we are told that chris continued that amount till retirement at 65, we are told that susan contributed the same amount for only that period between ages 25 and 35. Thus, it means that the reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

The inequality for a child up to and including 26 lb is the third option showing correct number line of inequality.

Given that the inequality is 0<x<=26.

We are required to choose the option which shows the correct number line of inequality.

Inequality is like an equation which shows the relationship between two or more variables but in greater than,less than,greater than or equal to ,less than or equal to signs.

Because we have to include 26 in the inequality so we need to fill the circle on 26. So, the correct option showing the correct inequality is third.

Answer:

  [tex]\textsf{C}\quad f^{-1}(x)=24-6x[/tex]

Step-by-step explanation:

You want the inverse function of f(x) = 24 -x/6.

The function relates x to y by y = f(x). The inverse function gives the reverse relation: x = f(y). Solving this for y gives the inverse function in the form you want.

  x = f(y)

  x = 4 -y/6 . . . . . use definition of f(x)

  6x = 24 -y . . . . multiply by 6

  y = 24 -6x . . . . add y-6x

  f⁻¹(x) = 24 -6x . . . . write using function notation

Answer:

1. A U C = {a, b, c, d, e}

2. B intersect A = {a, b, d}

3. B' = {c, f, g, h}

4. A - (B intersect C') = {a,c}

Step-by-step explanation:

U is a big set with all the letters a through f in it. Set A, B, and C are subsets of U. They have some of the letters in them. You could pick out the contents of set A, for example, from set U. Same with B and C. There's a little bit of overlap between A and B and C.

So for #1, the U shaped symbol means "Union" and you can remember that because of the U shape symbol. "Union" means throw everything in all together. A U C means all of A and all of C all together. But you don't have to write repeats, just list the letters once.

A is {a,b, c, d} and C is {a, e} so A U C is all of both of them:

{a, b, c, d, e}

The upsidedown Usymbol is "intersect" and that is only what the two sets have in common (whats the same) between the two sets.

BintersectA is what is the same in B{b,e,a,d} and A{a,b,c,d}. They both have a, b and d so that is the answer to BintersectA = {a,b,d}

The "apostrophe" looking mark means "Not this set". So B' means NotB. You list everything that is NOT in B. B is {b,e,a,d} so B' is NotB = {c,f,g,h}

The last one has what looks like a minus sign. Thats like normal "takeaway" along with parenthesis, use that normally like grouping/"do this first" and also intersect and Not. So basically all the work, all in one problem.

C = {a,e} so C' is NotC is {b,c,d,f,g,h}

The BintersectC' is what are the same beween B and NotC:

BintersectC' = {b,d}

A take away {b,d}

would be

{a,b,c,d} - {b,d}

= {a,c}
