Which of the equations below could be the equation of this parabola?
A. y = 4x2
B. x = 4y2
C. X=-4x2
D. Y=-4x2

Probability distributions can be represented using tables and graphs

The probability table is given as:

x              0       1        2       3      4

P(x) -> 0.191 0.319 0.287 0.128 0.074

The above table means that:

P(0) = 0.191

P(1) = 0.319

P(2) = 0.287

P(3) = 0.128

P(4) = 0.074

Next, we check if the table represents a probability distribution using:

[tex]\sum P(x) = 1[/tex]

So, we have:

[tex]\sum P(x) = 0.191 + 0.319 + 0.287 + 0.128 + 0.074[/tex]

[tex]\sum P(x) = 1[/tex]

The graph is not given. So, I will plot the graph

See attachment for the figure that represents the probability distribution

Answer:

speed of the plane = 190 mph

Step-by-step explanation:

Let x = speed of the plane, then speed of the car = x - 150

time = 200/(x - 150) = 950/x

Divide by 50 on both sides, get

4/(x - 150) = 19/x

Cross multiply:

4x = 19(x - 150)

4x = 19x - 19*150

15x = 19*150

x = 19*150/15 = 190

Answer: The answer is B !

Step-by-step explanation:

The x axis is left so negative units will go left!

The y axis is up and down so positive units go up!

Answer:

192 would be your answer.

Answer:

85 km

Step-by-step explanation:

to find this answer you must use the pythagorean theorem

this formula is basically a^2 + b^2 = c^2

so square the two sides that you have and thats the answer of the hypotenuse squared

68^2 + 51^2 = c^2

4624 + 2601 = 7225

then you must take 7225 to the square root

that is 85

Answer:

B. Since the y - values decrease as the x - values increase the scatter plots show a negative association.

Step-by-step explanation:

A positive association would be the y - values and the x - values both increases.

Step-by-step explanation:

area formula

Using diagonals:  A =  (d1 × d2) : 2

we use the inverse formula

A * 2 : d1

225 * 2 : 15 =

30cm

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

check

15 * 30 : 2 = 225

the answer is good

Answer:

Angle BPQ = 64°

Step-by-step explanation:

4x + 12 +2x = 90

6x + 12 = 90

     - 12    -12

6x = 78

x = 13°

BPQ = ((4(13) + 12)°

           (52 + 12)°

Answer:

Step-by-step explanation:

Since the triangles are similar, the ratio of corresponding sides are same.

ZX is the largest side and corresponding side is BC = 60, the shortest sides are BC = 40 and YZ = 20:

If y = x² - 1, then y + 1 = x² and y' = 2x. Then in the DE, we would have

2x = - (x² - 1) x² / x   ⇒   2 = - x² + 1

but this only true for some values of x. So the first choice is not correct.

If y = 2/(x - 2), then y + 1 = x/(x - 2) and y' = -2/(x - 2)². In the DE,

-2/(x - 2)² = - (2/(x - 2)) (x/(x - 2)) / x   ⇒   -2/(x - 2)² = -2/(x - 2)²

so the second choice is the correct answer.

Answer:

A)

Step-by-step explanation:

ratio of out of state fans to total number of fans:

640 : 1580 = 640/1580 = 32/79

So 32 out of every 79 fans were out of state fans

Answer:

A) 32 out of every 79 fans attending were out-of-state fans

Step-by-step explanation:

640 were out-of-state fans :  1,580 fans in the game

32 were out-of-state fans : 79 fans in the game

✔A) 32 out of every 79 fans attending were out-of-state fans

B) 47 out of every 79 fans attending were out-of-state fans

C) more than 47 out of every 79 fans attending were out-of-state fans

D) at least 32 out of every 79 fans attending were out-of-state fans

Answer:

D

Step-by-step explanation:

When doing this problem remember that absolute value is a number's distance from zero, and distance is always positive. So, absolute value makes any number positive. This means that |±x| = x. To find the correct number graph, first solve the inequality.

Subtract 1 from both sides

Divide both sides by 3

Then, we need to use absolute value. Any number with a distance from 0 greater than 2 fulfills this inequality. So, the number graph should represent -2 > x and x > 2. Additionally, because the inequality is looking for greater than but not equal to, the circles should be open.
