Bags of flour at a local grocery store have a mean weight of 83 ounces with a standard deviation of 2 ounces. Which weight represents the 65th percentile?
A.82.2 ounces
B.82.5 ounces
C.83.5 ounces
D.83.8 ounces

Answers

Answer 1

Answer:

D.83.8 ounces

Step-by-step explanation:

The z score for 65th percentile = 0.385

Mean weight of 83 ounces with a standard deviation of 2 ounces

The formula for calculating a z-score is z = (x-μ)/σ

where x is the raw score

μ is the population mean

σ is the population standard deviation

x = ??

Hence:

0.385 = (x - 83)/2

Cross Multiply

0.385 × 2 = x - 83

0.77 = x - 83

x = 83 + 0.77

x = 83.77 ounces

Approximately = 83.8 ounces

Answer 2

Answer:

D.83.8 ounces

Step-by-step explanation:

The z score for 65th percentile = 0.385

Mean weight of 83 ounces with a standard deviation of 2 ounces

The formula for calculating a z-score is z = (x-μ)/σ

where x is the raw score

μ is the population mean

σ is the population standard deviation

x = ??

Hence:

0.385 = (x - 83)/2

Cross Multiply

0.385 × 2 = x - 83

0.77 = x - 83

x = 83 + 0.77

x = 83.77 ounces

Approximately = 83.8 ounces

Step-by-step explanation:

students at Freeman Middle School have a choice of water milk or juice for breakfast from a survey it was determined that 50 students prefer water 100 prefer juice and 150 prefer milk. you want to know the probability that exactly 3 of 4 randomly selected students do not prefer water how could you model the scenario? This scenario can be simulated by Rolling a six-sided die (A 3 B 4 C 5 D 6 E 7 times). The (A numbers 0 to 3 B numbers 0 to 6 C number 1 D numbers 7 to 9 ) would represent students who prefer water if a number (A 0 to 3 B 0 to 6 C 1 D 7 to 9) appears only once in a set of outcomes then it will mean that three of four randomly picked students do not prefer water in that set .​

Answers

Answer:

The probability that exactly three of four randomly selected students that do not prefer water is; P=125/1296= 0.096

Step-by-step explanation:

Hope this helps

The required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.

Given that,
Students at Freeman Middle School have a choice of water milk or juice for breakfast.
From a survey, it was determined that 50 students prefer water 100 prefer juice, and 150 prefer milk.


What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

the probability that selected students to prefer water.
Total sample space = 300
Total desired events = 50
Pw = 50 / 300 = 1/6

the probability that selected students do not prefer water
Total sample space  = 300
Total desired events = 100+150 = 250

Pmj = (250)/300
     = 5/6


The probability for exactly 3 of 4 randomly selected students do not prefer water can be given as,

Preq =  Pmj.Pmj.Pmj.Pw

Preq = (5/6)^3 × 1/6

Preq= 125/1296
  = 0.096

Thus, the required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.

in a mixture a there is 2l of syrup in 3l of water. in a mixture b there is 1.8l of syrup in 2.5 water. in which mixture, concentration syrup is higher?

Answers

Answer:

Step-by-step explanation:

In the first mixture the concentration syrup is higher

Concentration syrup is higher in mixture B.

What is Proportion?

Two or more ratios made to be equal to each other is termed as proportion.

We have to use the proportional concept here by finding the concentration of syrup in 1 l of water.

Mixture A:

Concentration of syrup in 3 l of water = 2 l

Concentration of syrup in 1 l of water = 2/3 l = 0.67 l

Mixture B :

Concentration of syrup in 2.5 l of water = 1.8 l

Concentration of syrup in 1 l of water = 1.8 / 2.5 = 0.72 l

Concentration of syrup in mixture A in 1 liter of water is less than the concentration of syrup in mixture B in 1 liter of water.

Hence the concentration of syrup in mixture B is higher because concentration of syrup in mixture B in 1 liter of water is higher than the concentration of syrup in mixture A in 1 liter of water.

Consider the following table that describes the mass of a kitten as weeks go by. If you know the kitten grows by 10% each week for the first 5 weeks, fill in the table for the values each week. Week Mass (grams) (start) 80

Answers

Answer:

Week                   Mass  (gram)

(start)                    80

   1                         88  

   2                        96.8

   3                         106.48

   4                          117.128

Step-by-step explanation:

From the question we are told that

   The  mass of the kitten at the start week  is  m  =  80 g

   The rate at which the kitten grows is  r  =  0.10

Generally the mass of the kitten at the first  week is mathematically represented as  

    [tex]m_1 = ( r *  m)  + m[/tex]

=>[tex]m_1 = ( 0.10 *  80 )  + 80 [/tex]      

=>[tex]m_1 = 88 \ g  [/tex]      

Generally the mass of the kitten at the second week is mathematically represented as  

     [tex]m_2 = ( r *  m_1)  + m_1[/tex]

=>[tex]m_2 = ( 0.10 *  88 )  + 88 [/tex]      

=>[tex]m_2 = 96.8 \ g  [/tex]      

Generally the mass of the kitten at the third  week is mathematically represented as  

     [tex]m_3 = ( r *  m_2)  + m_2[/tex]

=>[tex]m_3 = ( 0.10 *  96.8)  + 96.8 [/tex]      

=>[tex]m_3 = 106.48  \ g  [/tex]      

Generally the mass of the kitten at the fourth  week is mathematically represented as  

     [tex]m_4 = ( r *  m_3)  + m_2[/tex]

=>[tex]m_4 = ( 0.10 *  106.48)  + 106.48 [/tex]      

=>[tex]m_4 = 117.128  \ g  [/tex]              

Week                   Mass  (gram)

(start)                    80

   1                        88  

    2                      96.8

Selecting a State Choose one of the 50 states at
random.
a. What is the probability that it begins with M?
b. What is the probability that it doesn't begin with a
vowel?

Answers

Answer:

PART ONE- 8/50 PART 2-38/50

Step-by-step explanation:

First of all, we know that there are 50 states. Lets see how many states begins with M first.

Maine‎ (27 C, 5 P)

Maryland‎ (28 C, 5 P)

Massachusetts‎ (29 C, 4 P)

Michigan‎ (28 C, 4 P)

Minnesota‎ (28 C, 2 P)

Mississippi‎ (27 C, 6 P)

Missouri‎ (25 C, 3 P)

Montana‎ (27 C, 6 P)

There are 8 states which means that the probabilty is 8/50 which simplifies to 4/25

We know that 12 states begins with a vowel. 50-12 is 38/50

The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.

Given that, Selecting a State, Choose one of the 50 states at random.

We know that, P(A) = n(A)/n(S)

where, P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.

a) There are 8 states which begins with M, that means the probability = 8/50 = 4/25 = 0.16

b) We know that 12 states begins with a vowel,

Therefore, the probability that it doesn't begin with a vowel = 1 - 12/50 = 38/50 = 0.76

Hence, The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76
