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.
-3×3 = -9:
12 + (-9)/2 + 3 (6 - 4/3)
Hint: | Put the fractions in 6 - 4/3 over a common denominator.
Put 6 - 4/3 over the common denominator 3. 6 - 4/3 = (3×6)/3 - 4/3:
12 - 9/2 + 3 (3×6)/3 - 4/3
Hint: | Multiply 3 and 6 together.
3×6 = 18:
12 - 9/2 + 3 (18/3 - 4/3)
Hint: | Subtract the fractions over a common denominator to a single fraction.
18/3 - 4/3 = (18 - 4)/3:
12 - 9/2 + 3 (18 - 4)/3
Hint: | Subtract 4 from 18.

- | | 4
| 1 | 4:
12 - 9/2 + 3×14/3
Hint: | Express 3×14/3 as a single fraction.
3×14/3 = (3×14)/3:
12 - 9/2 + (3×14)/3
Hint: | Cancel common terms in the numerator and denominator of (3×14)/3.
(3×14)/3 = 3/3×14 = 14:
12 - 9/2 + 14
Hint: | Put the fractions in 12 - 9/2 + 14 over a common denominator.
Put 12 - 9/2 + 14 over the common denominator 2. 12 - 9/2 + 14 = (2×12)/2 - 9/2 + (2×14)/2:
(2×12)/2 - 9/2 + (2×14)/2
Hint: | Multiply 2 and 12 together.
2×12 = 24:
24/2 - 9/2 + (2×14)/2
Hint: | Multiply 2 and 14 together.
2×14 = 28:
24/2 - 9/2 + 28/2
Hint: | Add the fractions over a common denominator to a single fraction.
24/2 - 9/2 + 28/2 = (24 - 9 + 28)/2:
(24 - 9 + 28)/2
Hint: | Evaluate 24 + 28 using long addition.

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.

The only zero of the equation 0=18c³−50c is c = 0, as it makes the equation true when substituted.
value is a zero of the equation 0 = 18c³ - 50c,
putting in the value for c
If c = 0:
0 = 18(0)³ - 50(0)
0 = 0 - 0
0 = 0 (True)
If c = 2:
0 = 18(2)³ - 50(2)
0 = 18(8) - 100
0 = 144 - 100
0 = 44 (False)
If c = -1:
0 = 18(-1)³ - 50(-1)
0 = 18(-1) + 50
0 = -18 + 50
0 = 32 (False)
only c = 0 is a zero of the equation 0 = 18c³ - 50c.
The equation 0 = 18c³ - 50c has only one zero, which is c = 0, as it satisfies the equation when substituted.

Given f(x) = -x + 7, find x when f(x)= -4
Answer:
x = 11
Step-by-step explanation:
f(x) = -x + 7
f(x) = -4
Using substitution, -x + 7 = -4
Then you can solve from there
-x + 7 = -4
-x = -11
x = 11

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.

Convert the decimal 0.92¯¯¯ to a fraction.
Question 4 options:
83100
8390
839
9299
Answer:
83/90
Step-by-step explanation:
you need to multiply the variable by 10. x =
0.9222… 10x = 9.222… 10x – x = 9.222… – 0.9222… 9x = 8.3 x =83/90
The decimal 0.92¯¯¯ is equal to the fraction 92/99.
So, the correct answer is 92/99.
Given that, a decimal 0.92¯¯¯, we need to convert it into fraction,
To convert the decimal 0.92¯¯¯ to a fraction, we can follow these steps:
Let's represent 0.92¯¯¯ as x.
Step 1: Multiply x by 100 to remove the repeating decimal:
100x = 92.92¯¯¯
Step 2: Subtract x from 100x to eliminate the repeating decimal:
100x - x = 92.92¯¯¯ - 0.92¯¯¯
99x = 92
Step 3: Divide both sides of the equation by 99 to solve for x:
x = 92/99
Therefore, the decimal 0.92¯¯¯ is equal to the fraction 92/99.
So, the correct answer is 92/99.
