Drag each number to the correct location on the table. Not all numbers will be used.
Airida [17]

Answer:

Complete Table:

Result of Roll ------ Frequency ------- Experimental Probability

1 --------------------------- 22 ------------------- 0.176

2 --------------------------- 13 ------------------- 0.104

3 --------------------------- 18 ------------------- 0.144

4 --------------------------- 29 ------------------- 0.232

5 --------------------------- 37 ------------------- 0.296

6 --------------------------- 6 ------------------- 0.048

Step-by-step explanation:

Required: Complete the table

The table is divided into 3:

1. Result of Roll

2. Frequency (F)

3. Experimental Probability (P)

The relationship between (2) and (3) is:

P = \frac{F}{N}

Where

N = Number of Rolls

N = 125

For Roll of Result = 2

Frequency = 13

The probability is calculated as thus:

P = \frac{13}{125}

P = 0.104

For Roll of Result = 3

Probability = 0.144

The Frequency is calculated as thus:

0.144 = \frac{F}{125}

F = 0.144 * 125

F = 18

For Roll of Result = 4

Frequency = 29

The probability is calculated as thus:

P = \frac{29}{125}

P = 0.232

For Roll of Result = 5

Probability = 0.296

The Frequency is calculated as thus:

0.296 = \frac{F}{125}

F = 0.296* 125

F = 37

For Roll of Result = 6

Frequency = 6

The probability is calculated as thus:

P = \frac{6}{125}

P = 0.048

For Roll of Result = 1.

To get the frequency; we subtract the sum of frequencies of roll of results 2 to 6 from the total number of rolls.

In other words:

Frequency of 1 = Total Rolls - (Frequency of 2 + Frequency of 3 + Frequency of 4 + Frequency of 5 + Frequency of 6)

Frequency of 1 = 125 - (13 + 18 + 29 + 37 +6)

Frequency of 1 = 125 - 103

Frequency of 1 = 22

The probability is calculated as thus:

P = \frac{F}{N}

P = \frac{22}{125}

P = 0.176

Find the measure of
lana [24]

Answer:

3y+4+2y+16=180 sum of two opposite angle of the cyclic quadrilateral is 180

5y=180-20

y=160/5=32

again

2x+58=180sum of two opposite angle of the cyclic quadrilateral is 180

2x=180-58

x=122/2=61

Alekssandra [29.7K]

Answer:

9.5

Step-by-step explanation:

Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.

Sena determines the remainder of 4x32−14x16+2x3−8x−1, using the remainder theorem. How does she proceed to the correct answer? D
Flauer [41]
Answer: x = 1 and -16

Explanation:

(4x^32 - 14x^16 + 2x^3 - 8)/x - 1

x - 1 = 0
x = 1

f(x) = 4x^32 - 14x^16 + 2x^3 - 8
f(1) = 4(1)^32 - 14(1)^16 + 2(1)^3 - 8
f(1) = 4 - 14 + 2 - 8
f(1) = -10 - 6
f(1) = -16

Therefore, the remainder is -16

The equation of a parabola in vertex form is y = 2(x - 3)2 + 5. What is the standard form
Alexxx [7]

hello :

y = 2(x + 3)² - 5

y = 2(x²+6x+9) -5

y = 2x² +12x +13...(answer : A) y=2x^2+12x+13 )

Option (a) is correct.

The standard form the equation  is

Step-by-step explanation:

Given : the vertex form of the  equation of a parabola is

We have to write the given equation in standard form and choose the correct from the given options.

Consider the given equation of parabola

The standard form of equation of parabola is

We can obtain the standard form by expanding the square term in the given equation.

Using algebraic identity , we have,

Solving brackets, we get,

Simplify, we get,

Thus, The standard form the equation  is
