in a game involving a pair of fair dice a player rolls the dice until he gets a sum of 7 let z equal the number of rolls it take

Anarel [89]

Answer:

z = 36 rolls , probability for getting 7 = 1/6

Step-by-step explanation:

A die has 6 possible outcomes, which sums to 36 for two dice for every value on both dice.

The outcomes for rolling both dice for 36 times gives 6 possible outcomes summing to 7, that is, (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1).

There the probability of getting a sum dice of 7 is:

= 6 / 36 = 1/6

A new car is purchased for 22400 dollars. The value of the car depreciates at 11% per year. To the nearest tenth of a year , how

m_a_m_a [10]

Answer:

t= 12.9 years

Step-by-step explanation:

Value after t years = initial value ( 1 - r )^t

Where,

Value after t years= $5000

Initial value = $22,400

r= depreciation rate = 11%

t= length of time (years)

Value after t years = initial value ( 1 - r )^t

5000 = 22,400 ( 1 - 0.11)^t

5000 = 22,400(0.89)^t

Divide both sides by 22,400

(0.89)^t = 5000 / 22,400

(0.89)^t = 0.2232

Take the log of both sides

t log 0.89 = log 0.2232

t= log 0.2232 / log 0.89

= -0.6513 / -0.0506

= 12.87

t= 12.9 years

Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and st

kirill115 [55]

The area of the shaded region is 0.1271 (12.71%).

<h3>What is the z score?</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)/standard deviation

Given:

Mean 0 and standard deviation 1. Hence, for z=-1.14:

P(z < -1.14) = 0.1271

The area of the shaded region is 0.1271 (12.71%).

Plz answer this question

Fed [463]

Answer:

x = 12, y=7

x=30, y=25

x=15, y=10

Step-by-step explanation:

We have : y = x - 5

x = 12 then y = 7, y = 12 - 5 = 7

x = 30 25 = x - 5, x = 25 + 5 = 30

x = 15, y = 15 - 5 = 10, y = 10
