Answer: option 1 is the correct answer

Step-by-step explanation:

Number of times for which the die was rolled is 360. It means that our sample size, n is 360.

The probability of rolling a 5 or a 6 is 1/3. It means that probability of success,p = 1/3. The probability of failure,q is

1 - probability of success. It becomes

1 - 1/3 = 2/3

The formula for standard deviation is expressed as

√npq. Therefore

Standard deviation = √360 × 1/3 × 2/3

= √80 = 8.9443

Standard deviation is approximately 8.9

URGENT PLEASE convert y = -5/6x -9 to standard slope form
SpyIntel [72]

Answer:

6y + 5x = -54  

Step-by-step explanation:

y = m x + b -> slope-intercept form

ax + by = c -> standard form

y = - \frac{5}{6} x - 9

6y = -5x - 54

6y + 5x = -54

How many cubic centimeters of water can this paper cone cup hold?
RUDIKE [14]
By definition, the volume of a cone is given by:
 V = (1/3) * (pi) * (r ^ 2) * (h)
 Where,
 r: cone radius
 h: height of the cone
 Substituting values:
 V = (1/3) * (3.14) * ((8/2) ^ 2) * (9)
 V = 150.72 cm ^ 3

 Answer:
 this paper cone cup can hold:
 
V = 150.72 cm ^ 3
