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 .
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.
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.

Find the slope given the following two points: (16,3) and (14, -19)
Answer:
the slope m=11
Step-by-step explanation:
(To find the slope use the equation m=[tex]\frac{y2-y1}{x2-x1}[/tex])
(16,3), where 16=x1 and 3=y1
(14,-19), where 14=x2 and -19=y2

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
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)

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?
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

Evaluate the expression 12-3y\2 + y(2y-4\y) for y =3
Answer:
43/2
Step-by-step explanation:
Evaluate 12 - (3 y)/2 + y (2 y - 4/y) where y = 3:
12 - 3 y/2 + y (2 y - 4/y) = 12 - 3×3/2 + 3 (2×3 - 4/3)
Hint: | Express -3×3/2 as a single fraction.
-3×3/2 = (-3×3)/2:
12 + (-3×3)/2 + 3 (2×3 - 4/3)
Hint: | Multiply 2 and 3 together.
2×3 = 6:
12 - (3×3)/2 + 3 (6 - 4/3)
Hint: | Multiply -3 and 3 together.

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?
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.

A body is floating in seawater with 2/3 of its volume above the surface. The weight of the displaced water is?
Answer:
The weight of the displaced water is the weight of the body
Step-by-step explanation:
In situations like this, the volume of the displaced water is not important.
However, it should be noted that when a body is immersed (fully or partially) in a liquid, the weight of the displaced liquid is equal to the weight of the body immersed in the liquid.
Since the weight of the body is not given, I'll conclude that the displaced water has the same weight as the body floating on the water.
