2 less than five times a number is equal to -17

information about the age of the respondents is missing, so i have attached it.

Answer:

Option A: We are 95% confident that the interval 29.7215 to 30.5029 includes the population mean age of all respondents.

Step-by-step explanation:

From the attached information given, we see that under the 95% Confidence interval column, that the corresponding mean age of all respondents is the interval 29.7215 to 30.5029.

Now, the mean is population mean because it's the mean of all the respondents in the population.

Thus, the correct answer is;

We are 95% confident that the interval 29.7215 to 30.5029 includes the population mean age of all respondents.

Answer:

29,205

Step-by-step explanation:

100% - 17.5% = 82.5%

82.5% * 35,400 = answer

make percent a decimal

.825 * 35,400 = 29,205

29,205 is answer

The required current value of the ambulance is given as $29,205.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,

The value of an ambulance depreciated by 17.5% from the purchase price of $35,400 a year ago.

Current price = 35400[1 - 0.175]
Current price =  $29,205

Thus, the required current value of the ambulance is given as $29,205.

I believe it is 50 degrees

Explanation:

180-115 = 65 degrees

Since the base angles of of an isosceles triangle are equal,

Angle C =angle A= 65 degrees

65 times 2 = 130

180-130=50

50 degrees=measure of angle B

Answer:

3

Step-by-step explanation:

The cardinality of a set a measure of the number of elements in a set.

A set is a group of objects that have a well defined relationship between them.

In the given set,  A={1,4,9}​

 The set of A has 3 elements which are 1, 4 and 9

So, the cardinality of this set is 3.

Answer:

A regular polygon is a polygon that is equilateral and equiangular.

The only regular quadrilateral is the square.

We know that all the interior angles of a square are 90° each, so we are fine with that.

Now, for the exterior angles.

If we fix our position in the vertex, we can do from one side, to the same side, a full rotation of 360°.

Now, if we only do an external rotation, this means, from one side to other side, we will do a rotation of 360° minus the interior angle:

this is:

360° - 90° = 270°

Below is an image as a guide of this.

Answer:

Step-by-step explanation:

= [tex](-\frac{\sqrt{3}}{2} - \frac{1}{2}i)^1^2[/tex]

= [tex](-\frac{\sqrt{3}}{2} - \frac{i}{2})^1^2[/tex]    

= [tex](\frac{\sqrt{3} -i}{2})^1^2[/tex]

apply the exponential rule:

    ([tex]-\sqrt{3}-i[/tex])¹²

=  --------------

         2¹²

note: ([tex]-\sqrt{3}-i[/tex])¹² = 4096

= 4096

Answer:I have this same problem but if you’re asking for the independent and other questions here’s the answer. Independent variable is the radio since that’s the only change happening to the 10 other pots. Dependent variable is the height of the plant since that’s what Ramona wants to see change as the output. Control group is the 5 pots without the radio i’m pretty sure. The constants are the amount of seeds, pots, soil, and water.

I hope my answer helps even though I am in middle school :)

The required percent decrease in the price of the skateboard is 40%.

The original price for its Extreme Skate Board was $84.50. The sale price for the skateboard is $50.70. What is the percent decrease in the price of the skateboard is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Original price = $84.50
sale price = $50.70
Percent decrese = 84.50-50.70/84.50 × 100 = 40%

Thus, the required percent decrease in the price of the skateboard is 40%.

Hi! I'd be happy to help you. However, there is not enough information here for us to help, as there is no way to tell which graph is correct without the equations of f(x) and g(x). They'd look something like:

"f(x) = x-2," or "g(x) = 7x+3."

Are you able to provide the equations of of f(x) and g(x)? I would be more than happy to help.

----------------------------------------------------------------------------------------------------------------

UPDATE: I did not realize that you could solve this problem without the original equations. Please refer to the other user's response for an amazing and detailed explanation of this problem! :)

Answer:

The first graph.

Step-by-step explanation:

We want to find the graph that shows:

[tex]h(x)=f(x)g(x)[/tex]

Notice that g(x) is a line and f(x) is a quadratic.

So, their product must be a cubic.

Also, g(x) and f(x) is the same across all four graphs. The only difference is h(x).

Notice that our quadratic f(x) is curving upwards. Therefore, the leading coefficient of f(x) is positive.

Notice that the line g(x) is sloping downwards. Therefore, the leading coefficient of g(x) is negative.

So, this means that the leading coefficient of our cubic h(x) must be negative since a positive times a negative yields a negative.

Remember that the parent cubic function has a positive leading coefficient and it rises from left to right.

So, if our leading coefficient is negative, the cubic will fall from left to right.

Therefore, we can eliminate the 2nd and 3rd graphs since in those two, h(x) has a positive leading coefficient.

Now, we can just pick a test point and determine whether our graph is the first or the fourth.

Let's let x = -2. So, we have the equation:

[tex]h(x)=f(x)g(x)[/tex]

Substitute all Xs for -2s:

[tex]h(-2)=f(-2)g(-2)[/tex]

Looking at the graphs, we can see that f(-2) is 8. g(-2) is 0.5. Substituting this back, we get:

[tex]h(-2)=8(.5)=4[/tex]

So, h(-2) should be 4.

For the first graph, h(-2) is indeed 4.

For the second graph, h(-2) is 6.

So, the correct graph that represents f(x)g(x) is the first graph.

And we're done!

Answer:

Step-by-step explanation:

Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:

17x+3 = 57

because they are corresponding sides of both triangles. To further solve the equation:

17x = 54 --> x = 54/17 --> 3 3/17

Same thing for Y. lines PX and FD are congruent, so, you can say:

4y-3 = 54

4y=57

y= 14.25

Solve the equation to find the cost of each mask.

Answer:

y = (-3x/5) +1

Step-by-step explanation:

We know that the line passes through the point (-5 , 4)

AND

the slope is given to be -3/5

let's look at the slope a bit more

we know that the formula for slope of a line is Rise / Run

Which means that the rise of this line is -3 after spanning 5 units to the right

Hence, the line goes down 3 units after moving 5 units to the right

We know that to find the equation of a line through the point-slope equation, we need the slope as well as the y-intercept of the line

since we are already given the slope, we need to find the point where the line intersects the y-axis

Now, back to the given point the line passes through

this point has a x - coordinate of -5 and we know that after moving 5 units to the right, the line moves 3 units downwards

So, if the line moves 5 units to the right from the given point, it will reach the y- axis and we know that it's y-coordinate will decrease by 3

Hence, the y-intercept will be 3 units below the given y -coordinate

y - intercept = (4 - 3) =  1 = y-intercept

Now, using the slope-intercept formula to get the equation:

y =  (slope)*x + (y-intercept )

y = (-3/5)x + (1)

y = (-3x/5) + 1

5x + 10y = 25    x=1  y=2

Answer:

  -9.5

Step-by-step explanation:

The slope (m) is the ratio of the change in y to the change in x:

  m = (y2 -y1)/(x2 -x1)

  m = (10-(-9))/(-3-(-1)) = 19/-2

  m = -9.5

The slope of that line is -9.5.
