Answer:

1547.085966 (rounded to the nearest whole number) - 1547

Step-by-step explanation:

Use the exponential decay formula

y = a (1 - b)^x

y =2700(1 - 0.06)^9

y = 1547.085966 ~ 1547

Answer:

1. 7x+5y=19    

(+)-7x-2y=-16       step one

____________

[tex]\frac{3y}{3\\}[/tex]=[tex]\frac{3}{3}[/tex]                   step two

y=1

____________

since you have the value of y u can plug it in in either of the equations.

7x+5(1)=19        step three

____________

7x+5-5=19-5     step four

____________

[tex]\frac{7x}{7}[/tex]=[tex]\frac{14}{7}[/tex]

x=2                     step five

____________

You can check whether the answers are correct by plugging them back in.

7(2)+5(1)=19

14+5=19

19 equals 19 so it checks.

You can do the same thing for the rest.

Answer:

C. 5 times the MAD

Step-by-step explanation:

The difference between the mean cost to treat dogs at No Ruff Stuff Animal Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is about 5 times the MAD. This is a large difference.

The correct option is C.

In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the number of observations).

Given:

The mean cost to treat dogs at No Ruff Stuff Animal Hospital is $224.65.

And MAD = $20.52

The mean cost to treat cats at No Ruff Stuff Animal Hospital is $124.84.

And MAD = 19.75.

The difference between the mean cost to treat dogs at No Ruff Stuff Animal

Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is,

= 224.65 - 124.84.

= 99.81

= 5 x 19.75

Therefore, the difference is 5 times MAD.

Answer:

-4

Step-by-step explanation:

Answer:

According to the numbers provided, the sequence is:

5, 6, 1, 4, 7, 3, 2

Solution of the two lines intersecting in the graph is answer B

The inequality that represents the graph is that of answer A

Step-by-step explanation:

First problem:

This is the sequence to solve for "x" once the substitution was made;

[tex]3x +2\,(x+3)=11\\3x+2x+6=11\\5x+6=11\\5x=11-6\\5x=5\\x=1\\[/tex]

Now that we know x, we use its value (1) in the substitution equation in order to find "y" and complete the ordered pair:

[tex]y=x+3\\y=1+3\\y=4[/tex]

Then the solution pair (x, y) is: (1, 4)

Therefore, according to the numbers provided in the list of possible steps, the order is:

5, 6, 1, 4, 7, 3, 2

Second problem:

The solution to the system is where the two lines two lines intersect: "the point -1.5 on the x axis. Notice that -1.5 can be written in fraction form as -3/2, this is the x-coordinate of the intersection point. The y-coordinate is y-0 since the point is on the x-axis. Therefore the point is (-3/2, 0) which is given by answer B).

Third problem: The boundary line seems to go through the points: (-4, -10) and (0, -2), so we can calculate the slope via the equation:

[tex]slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{-2-(-10)}{0-(-4)}\\slope=\frac{8}{4}\\slope=2[/tex]

since the line's y-intercept is (0, -2), then the equation of the boundary line in slope-intercept is:

[tex]y=2x-2[/tex]

Since the shaded region includes the boundary line and the zone above it (with y-values larger than or equal to those point in the line), we can say that the inequality that represents this graph is:

[tex]y\geq 2x-2[/tex]

which corresponds to answer A

Answer: A

and hopefully I did it right!

I tried my best!!

The volume of the trapezoidal prism comes to be 312 cubic units.

The volume of a prism is the product of the base area and its height.

So, the volume of the given prism = area of trapezoidal base * height

Area of the trapezoidal base = 0.5 * (sum of parallel sides) * distance between parallel sides.

Area of the trapezoidal base =0.5 * (8+5) * 4

Area of the trapezoidal base =26 square unit

So, the volume of the given prism = 26*12 = 312 cubic units.

Hence, the volume of the trapezoidal prism comes to be 312 cubic units.

59% of women will be a part of the work force in 1996

According to the bars, the percentage was in the range of 57.5 - 60.2. This verify the previous result.

Step-by-step explanation:

In the figure attached, the bar graph is shown.

f(x) = 3.5√x + 38

where f(x) models the percentage of U.S. women in the labor force x years after 1960. In 1996, x = 1996 - 1960 =  36. Replacing it into the equation:

f(36) = 3.5√36 + 38 = 59%

Answer:

C. 3.4

Step-by-step explanation:

We need to find expected value, which is essentially the value that we expect to get based on the amount of each "thing" at hand.

Here, we have 4 multiple-choice questions worth 3 points each and 2 true/false questions worth 1 point each. Each multiple-choice question has 5 possible answers, so the probability that you get that multiple-choice question correct is 1/5. Similarly, each true/false question has 2 possible answers, so the probability that you get that question right is 1/2.

Expected value, denoted by E(x), has the formula:

E(x) = ∑ xp(x), where x is the number of points you get per problem here and p(x) is the probability of getting the problem correct

E(x) = 4 * 3 * (1/5) + 2 * 1 * (1/2) = 12/5 + 1 = 17/5 = 3.4.

The answer is thus C.

Step-by-step explanation:

(-3,8) ( 4,1)

8-1= 7

-3-4 = -7

7/-7 = -1  so the slope is -1   so we will use the formula y=mx+b to find the y-intercept

8= -1(-3) + b

8= 3 + b

-3   -3

b= 5  so the y intercept is 5 now we will write the equation like this y= -1x + 5

Answer:

D

Step-by-step explanation:

plato

The equation of this graph would be (x − 5)^2 = -8(y + 4). So option D is correct.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.

If we know that the function crosses x axis at some point then for some polynomial functions, we have those as roots of the polynomial.

Hence,  the equation of this graph would be (x − 5)^2 = -8(y + 4).

So option D is correct.
