In a recent study at a local college using a simple random sample, 9 students admitted that they had tried alcohol at least once

while under the legal drinking age, while 6 students said they had not. Is there enough data to conduct a hypothesis test to see if the percentage of students at the college who admit to drinking underage is the same as the national percentage of 65%

A bag contains six red marbles three blue marbles and five green marble the three marbles are drawn out of the bag what is the p
tia_tia [17]

Answer:

Step-by-step explanation:

Red = 6

Blue = 3

Green = 5

Total = 14

First marble = 6/14  = 3/7  You now have 5 reds and 13 total

Second Marble = 5 * 13  which brings you down to 4 red and 12 total.

Third Marble = 4/12 = 1/3

Result

P(3 Red) = 3/7 * 5/13 * 1/3     cancel the 3s

P(3 Red) = 1/7 * 5/13

P(3 Red) = 5/91

P(3 Red) = 0.0549 . Rounding to the nearest 1/100 depends on what you have been told about rounding. I would say the answer is 0.05 but your teacher may say something different.

A mixture weighing 600kg has two ingredients: sand, cement and stones. There is twice as much cement as sand and three times as
Brilliant_brown [7]

Answer:

Step-by-step explanation:

All the masses here are based on the main mass of the sand.  So we will call sand "x".  If there is two times as much cement as sand, then cement is 2x; if there is three times as much stone as sand, then stone is 3x.  All of these added together equal a mass of 600 kg:

x + 2x + 3x = 600 so

6x = 600 and

x = 100 kg

There are 100 kg of sand.  That means that there is 200 kg of cement and 300 kg of stone

RoBoCo Costume Inc plans to launch a major campaign to sell Robby the Robot costumes for Halloween. The price-demand equation fo
Neko [114]

Answer:

x = 20,000

p = $40

If the price increase by $1, the demand will decrease by 1000

Step-by-step explanation:

Given:

x = 160 - p

x = number of Robby costumes demanded in thousands

p = price in dollars.

a. How many costumes can be sold at a price of $140?

x = 160 - p

x = 160 - 140

= 20

x = 20,000

20 thousand costumes can be sold at a price of $140

b. What price should be charged if the demand is 120,000 Robby costumes?

x is in thousand

p is in dollars

x = 160 - p

x + p = 160

120 + p = 160

p = 160-120

= 40

p = $40

c. If the price increases by $1.00, by how much does the demand decrease?

x = 160 - p

= 160 - 141

= 19

x= 19,000

If the price increase by $1, the demand will decrease by 1000
