Step-by-step explanation:

Answer:

No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate

=> 52 + 3w >= 90

Step-by-step explanation:

Given that Antonina needs to have worked at least 90 volunteer hours to graduate means that she needs to volunteer either for 90 hours or more than that . Mathematically this can be written as

Total volunteer hours required to graduate greater than or equal to 90

Total volunteer hours required to graduate>= 90

No. of hours already volunteered = 52

no. of hours left for volunteering = Total volunteer hours required to graduate - No. of hours already volunteered = 90 - 52 = 38

No. of hours in one week she can dedicate for volunteering= 3

if w is the number of weeks that Antonina needs to tutor in order to complete her volunteer hours

then total volunteer hours dedicated in w weeks will be = w*No. of hours in one week she can dedicate for volunteering = w*3 = 3w

Thus,

No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate

=> 52 + 3w >= 90

Answer:

y = - 3x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute (- 1, - 1) into the partial equation

- 1 = 3 + c ⇒ c = - 1 - 3 = - 4

y = - 3x - 4 ← equation of perpendicular line

Answer:

The equation of the line of best fit is: y = -2.33x + 591.78

The correlation coefficient is: -0.99

There is a strong negative correlation

Step-by-step explanation:

The negative correlation is seen in the sign of the correlation coefficient, which is negative.

The correlation is strong because the absolute value of the correlation coefficient (0.99) is near to one

Step-by-step explanation:

The mean of this number is 16 because when you do the formula it adds up to 16, so the formula to find the mean of the numbers is: Firstly you order the numbers from smallest to largest, Next you add all the numbers together and divide the answer you get with the amount of the numbers you were talking about in the question.

Answer:

The sum of the two leg measures equals the hypotenuse.

Step-by-step explanation:

The answer choice "The measure of the hypotenuse squared is equal to the sum of the side measures squared" is true because it is the Pythagorean Theorem.

The other two answer choices basically describe what a hypotenuse is.

Answer:

The sum of the two leg measures equals the hypotenuse.

Answer:

Both are correct because after substituting the same value into both expressions, the result is the same.

Step-by-step explanation:

Given the expression:

(1/6)*(6*x + 12) - (1/2)*(4*x + 2)

Applying distributive property:

(1/6)*6*x + (1/6)*12 - (1/2)*4*x - (1/2)*2 =

= x + 2 - 2x - 1 =

= -x + 1

Then, for any number substituted into both equations, the result is the same

Answer:

c: Both are correct because after substituting the same value into both expressions, the result is the same.

Step-by-step explanation:

Remember that triangle's area is 1/2 x b x h. But we have 2 congruent triangles so we have 2 x 1/2 x b x h. so the area of 2 triangles is b x h.

You should know the areas of other sides.

Answer:

The angle of the shaded region is 124.9°

Step-by-step explanation:

Since there's an region inside the circle that is shaded and has an area of 34 pi square units, we can apply the circle's sector area's formula in order to find the angle of this region. The formula is given by:

[tex]\text{sector area} = \frac{\text{angle}*\pi*r^2}{360}\\[/tex]

Applying the data from the problem gives us:

[tex]34*\pi = \frac{angle*\pi*(7*\sqrt{2})^2}{360}\\34 = \frac{angle*(49*2)}{360}\\98*angle = 34*360\\angle = \frac{12240}{98} = 124.9\°[/tex]

The angle of the shaded region is 124.9°

Answer: x-intercept

The x-intercept is the point where a line crosses the x-axis.

All x-intercepts have a y-coordinate of 0.

As an ordered pair, we can write this as (-19.164, 0).

Answer:

Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.

We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.

Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other

Answer:

x = 9

Step-by-step explanation:

We know sum of interior angles of a polygon = [tex](n-2)\times 180[/tex]

For a triangle (having n = 3),

Sum of interior angles = (3 - 2)×180°

                                     = 180°

In ΔVWX,

m∠V = (12x + 19)°

m∠W = (2x + 19)°

m∠X = (x + 7)°

And m∠V + m∠W + m∠X = 180°

(12x + 19)° + (2x + 19)° + (x + 7)° = 180°

(12x + 2x + x) + (19 + 19 + 7) = 180°

15x + 45° = 180°

15x = 180° - 45°

x = [tex]\frac{135}{15}[/tex]

x = 9

Therefore, value of x = 9.
