Answer:

36.5

Step-by-step explanation:

y= -x²+73x-520

which can be represented as ax²+bx+c

a= -1, b= 73, c = -520

for maximum value of y,

the formula is

c - (b² / 4a)

= -520 - (73² / 4×(-1))

= -520 - (5329 / -4)

= -520 + 1332.25

= 812.25

Solving for x,

812.25 = -x²+73x-520

or, x²-73x+ 1332.25 = 0

Solving,

x= 36.5

Answer: 3 science fiction novels and 3 mystery novels

Explanation:

10x + 2x = 36

12x = 36

x = 3

10(3) + 2(3) = 36

meaning 3 of each book

Answer:

For some sets of data, some of the largest value, smallest value

, first quartile, median, and third quartile may be the same. For instance, you might have a data set in which the median and the third quartile are the same. In this case, the diagram would not have a dotted line inside the box displaying the median. The right side of the box would display both the third quartile and the median. For example, if the smallest value and the first quartile were both one, the median and the third quartile were both five, and the largest value was seven, the box plot would look like:

In this case, at least

25

25

% of the values are equal to one. Twenty-five percent of the values are between one and five, inclusive. At least

25

25

% of the values are equal to five. The top

25

25

% of the values fall between five and seven, inclusive.

Answer:

First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.

Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.

Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.

Voila, my friend. You have a box plot.

Answer:

3:2

Step-by-step explanation:

Answer:

3:2

Step-by-step explanation:

6 and 4 can be both divided by 2

Answer: 10

Step-by-step explanation:

a 30° - 60° - 90° triangle has a side ratio of 1:√3: 2, meaning the side length across from the 30° is 1, the side length across from 60° is √3, and the side length across from 90° is 2

if you multiple the 1 * 5 = 5 (the 5 side length in the diagram), then also multiple (5 * √3 = 5√3) and (2 * 5 = 10)

since you're looking for the hypotenuse (the length across the 90°), the answer would be 10 (2 * 5 = 10)

*this method can work for any 30° - 60° - 90° triangle

you can also use trig:

sin (30°) = [tex]\frac{5}{x}[/tex] (now just solve for x)

x * sin (30°) = 5

x = [tex]\frac{5}{sin(30)}[/tex]

x = [tex]\frac{5}{1/2}[/tex] ( because sin (30°) = 1/2 )

x = 5 * [tex]\frac{2}{1}[/tex] = 10

*either method works!

Answer:

1/10

Step-by-step explanation:

For multiplying fractions, just multiply the numerators by eachother and the denominators by eachother.  (The number on top being the numerator and the number on bottom being the denominator.)  

3 × 4 = 12 and 8 × 15 = 120, so your answer so far is 12/120.  

Divide 12 and 120 by something that goes into both of them, I'll do 6, and you get 2/20.  2/20 is equal to 1/10, which is the lowest you can go, therefore being the final answer.  (If you are allowed to simplify, just put 12/120 as your answer.)

I hope this helps!  Don't worry, your not bad, I hard a hard time with fractions too.  :)

Answer: The probability of the pointer lands on red(R) both spin =

Step-by-step: The number of parts = 6

The pointer is spun twice.

To find the probability of the pointer lands on red(R) both spin.

Formula

Probability of an event = number of required outcomes ÷ the total number of outcomes.

P(A and B) = P(A)×P(B)

Now,

For one spin,

A = RED comes.

For second spin,

B = RED comes

So,

P(A) = and P(B) =

Then,

P(A and B) = × =

Hence, the probability of the pointer lands on red(R) both spin =

Answer:

2

Step-by-step explanation:

rate of change of Function 2 is 2

rate of change of Function 1 is 0

2 - 0 = 2

Step-by-step explanation:

9 + y^2 = 49

y^2 = 40

y = √40 = 2√10

4.5/3 = 2√10/5x

22.5x = (3) 2√10

22.5x = 6√10

x = 6√10/22.5 = 3√10/11.5

Answer:

slope= rise over run means divide rise by run

Answer:

when there is a linear equation and line. first, find where you see a point that has whole numbers. graph them or circle them. Next, go to point to pint using the lines. do not use the slanted line. go up (rise) and count how many boxes you passed (be careful it could go by 2's) and then go across to the other point (run). count how many boxes you passed. now you put the up number or rise number over the run number. Rise/run. you'll get a fraction, simplified it if needed.

or do slope form which is just find 2 points that have whole numbers. Label the first one (x1,y1) and the second one (x2,y2) the you do (Y2 - Y1) over (X2 - X1). you'll get a fraction and you'll simplified it if needed

Answer:

y = -3x - 10

Step-by-step explanation:

Answer:

y= -3x-10

Step-by-step explanation:

To answer this question we can use this formula

y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point,

y-(-4) = -3(x-(-2)

y+4= -3(x+2)

y = -3x-6-4

y= -3x-10

The tangent line and radius or diameter of the circle intersect at a right angle and the tangent intersects the circle at a single point only. Then the correct option is A, B, and D.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The tangent line and radius or diameter of the circle intersect at a right angle.

And the tangent line intersects the circle at a single point only.

The number of the tangent line depends on the point from which the tangent is drawn.
