Using the line of best-fit, it is found that the residual for the player is of 12.6.

A residual is given by the difference between the observed point and the predicted point.

In this problem, the expected score over x hours is given by:

f(x) = 280.3 + 85.7x.

Hence, for 3 hours, the predicted score is given by:

f(3) = 280.3 + 85.7 x 3 = 537.4.

The observed score was of 550, hence the residual is given by:
R = 550 - 537.4 = 12.6.

Answer:

m=-2 and b=3

Step-by-step explanation:

One way to find slope is to use rise over run (most useful when there is a graph). First find any two points along the line where it intersects with a point on the grid. (1,1); (2,-1) and (3,-3) are some examples. Then count how many spaces vertically and then horizontally it takes to get to the next point. In this case it is two spaces down (rise) and 1 space right (run). So rise/run = 2/1 =2. That is your slope. Because it is pointing downwards or decreasing we know it is a negative slope.

The y-intercept is just where the line intercepts with the y-axis. In other words, when x=0 what does y equal? Here it is 3.

Answer:

58 degrees

Step-by-step explanation:

90-32

Answer:

angle b measures 58°

Explanation:

As we know that, the sum of complementary angles is always equal to 90°.

Therefore,

angle a + angle b = 90°

32° + angle b = 90°

angle b = 90° - 32°

angle b = 58°

Answer:

Step-by-step explanation:

The vertex form of quadratic function f(x) = ax² + bx + c:

f(x) = a(x - h)² + k

(h, k) - coordinates of a vertex

h = -b/2a

k = f(h)

We have f(x) = -x² + 8x - 4 ⇒ a = -1, b = 8, c = -4.

h = -8/(2 · (-1)) = -8/(-2) = 4

k = f(4) = -4² + 8 · 4 - 4 = -16 + 32 - 4 = 12

Vertex (4, 12)

Answer:

A pythagorean identity means that for any angle [tex]\theta[/tex], [tex]sin^2\theta+cos^2\theta=1[/tex].

This also means [tex]1+tan^2\theta=sec^2\theta \mbox{ and } 1+cot^2\theta=csc^2\theta.[/tex] The symbol, theta ([tex]\theta[/tex]) represents one of the acute angles in the right triangle. The hypotenuse (familiarly c in the regular pythagorean theorem) is 1. The triangle base is [tex]cos\theta[/tex], and the height (side perpendicular to the base, making a right angle) is [tex]sin\theta[/tex]. The angle theta is opposite the [tex]sin\theta[/tex] side.

Step-by-step explanation:

The pythagorean theorem applies to right triangles, which always have a 90 degree angle. Pythagorean identities are used to simplify trigonometric expressions/evaluate trig functions and to find the trig ratios in a right triangle.

Answer:

The Pythagorean identities are

[tex]sin^{2} x + cos^{2} x = 1\\1+ tan^{2} x = sec^{2} x\\1 + cot^{2} x = csc^{2} x\\where\\csc x = \frac{1}{sinx} \\cot x = \frac{cosx}{sinx} or \frac{1}{tanx} \\tan x = \frac{1}{cotx} or \frac{sinx}{cosx} \\sec x = \frac{1}{cotx}[/tex]

No matter what the value of x (the angle degree amount) is, sin²x+cos²x is equal to 1

When given a side length of a right triangle you will be able to use one of these identities to find the angle amount

Step-by-step explanation:

If we let the length of the base be b, then the height is 2b-9.

This means that (1/2)(b)(2b-9)=9

b(2b-9) = 18

2b^2 - 9b = 18

2b^2 - 9b - 18 = 0

(2b+3)(b-6)=0

b = -3/2 or b= 6 (disregard b = -3/2 as distance is positive)

This means b =6, and thus the height is 2(6)-9=3.

The number of eight-digit codes could she make using the digits in her birthday is 1120 digits

Since the order of the arrangement of the digits matter, we use permutations

Permuations are the number of ways of arranging n objects in r ways. It is given as ⁿPₓ = n(n - 1)(n -2)...(n - x + 1). If we have r identical objects out of n objects, the number of arrangements are n!/r!

Now, since in the date Lucy was born 11/09/1993 has eight digits, we need to find the number of permutations the eight digits of her birthday to form an eight digit code.

Since there are 8 digits, three one's, three nine's, one 1 and one 3.

The number of permutations of these digits in an eight digit code, since we have repeated objects are n = 8!/3!3!1!1!

= 40320/6 × 6 × 1 × 1

= 40320/36

= 1120 digits

So, the number of eight-digit codes could she make using the digits in her birthday is 1120 digits

180=41+2a+a-14

180=3a+27

153=3a

Answer:

a=51

Explaination-

ABC + ACB + BAC = 180°

(a-14)° + 2a + 41° = 180°

a=51

Part A: The x-intercept represents the maximum amount of profit the company makes depending on the price of erasers. The intervals would be the prices of the erasers, and they represent the correlation between sale and profit. For example, when each eraser costs $4, the company makes the max profit of $270.

Part B: The average rate of change would be $91.875 and the rate represents that, on average, for each dollar that the price of the eraser jumps, the profit jumps an average of $91.875.

Part C: The constraints of the domain would be things like how the price of the erasers cannot go less than $0 or above $8; 0 [tex]\leq[/tex] x [tex]\leq[/tex] 8.

Answer: 1.5 (Decimal Form) or 3/2 (Exact Form)

Step-by-step explanation:

So what you do is put the whole number which in this case is 4, into a fraction so your problem will look like this:

3 / 8 * 4 / 1 =

Then, you will have to multiply all the numbers across:

3 * 4 = 12

8 * 1 = 8

Your answer will then look like this:

12 / 8

You will have to simplify with the greatest common factor which would be 4:

12 / 4 = 3

8 / 4 = 2

So, you get your answer:

3 / 2 or 1.5
