which of the following cannot be the probality of an event a)1/2 b) 10% c) 0.7. d) 3/2. which is the correct option with the solution
Answer:
D
Step-by-step explanation:
In probability,
a probability of 0 means that it is IMPOSSIBLE, sure that this event WILL NOT occur, ever. So, probability of anything less than 0 is not possible.
On the other hand, probability of 1 means that it is CERTAIN to happen. So, probabilty of anything greater than 1 can't happen.
So we can say:
0 <= Probability of an Event happening <= 1
Option A is 1/2, which is in the middle, so this is OKAY.
Option B is 10%, which is certainly close to 0 and between 0 and 1, so this is OKAY.
Option C is 0.7, which is close to 1 and greater than 0, so in between 0 and 1, certainly. So this is OKAY.
Option D is 3/2 which is 1.5, so this is GREATER THAN 1, so it can't ever be possible.
Option D is the correct choice.

Jennifer feeds 5 times as many fish as Tony. Tony feeds 56 fish. how many fish,f,does Jennifer feed?
Answer:
Jennifer feeds total fishes is 280
Step-by-step explanation:
Tony feeds total fishes is 56
Jennifer feeds 5 times as many fish as Tony feeds
Jennifer [tex]=[/tex] 5 × Tony
[tex]=[/tex] 5 × 56
[tex]=[/tex] 280
Jennifer feeds total fishes is 280
Final answer:
Jennifer feeds 280 fish.
Explanation:
To find out how many fish Jennifer feeds, we need to perform a simple multiplication. Since Jennifer feeds 5 times as many fish as Tony, and Tony feeds 56 fish, we can write the following equation to represent the situation:
f = 5 × 56
We then multiply 56 by 5:
f = 280
So, Jennifer feeds 280 fish.

Answer:
X=15 divided by 2
Step-by-step explanation:
Where X equals 5.
Answer:
[tex]5x + 2\frac{1}{2} = 15[/tex] and [tex]\frac{15 - 2\frac{1}{2} }{5}[/tex]
Step-by-step explanation:
Assume the length of each piece of wood is x feet.
We can say that the length of uncut board = (number of pieces × length of each piece) + length of leftover board, or [tex]15 = 5x + 2\frac{1}{2}[/tex].
Apply the Symmetric Property of Equality:
[tex]5x + 2\frac{1}{2} = 15[/tex]
Subtract [tex]2\frac{1}{2}[/tex] from both sides of the equation:
[tex]5x = 15 - 2\frac{1}{2}[/tex]
Divide both sides by 5: (See image)
Cancel out the common terms from the numerator and denominator:
[tex]x = \frac{5}{2}[/tex]
[tex]= 2\frac{1}{2}[/tex]
In a certain Algebra 2 class of 30 students, 19 of them play basketball and 12 of them play baseball. There are 8 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
Probability that a student chosen randomly from the class plays basketball or baseball is [tex]\frac{23}{30}[/tex] or 0.76
Step-by-step explanation:
Given:
Total number of students in the class = 30
Number of students who plays basket ball = 19
Number of students who plays base ball = 12
Number of students who plays base both the games = 8
To find:
Probability that a student chosen randomly from the class plays basketball or baseball=?
Solution:
[tex]P(A \cup B)=P(A)+P(B)-P(A \cap B)[/tex]---------------(1)
where
P(A) = Probability of choosing a student playing basket ball
P(B) = Probability of choosing a student playing base ball
P(A \cap B) = Probability of choosing a student playing both the games
Finding P(A)
P(A) = [tex]\frac{\text { Number of students playing basket ball }}{\text{Total number of students}}[/tex]
P(A) = [tex]\frac{19}{30}[/tex]--------------------------(2)
Finding P(B)
P(B) = [tex]\frac{\text { Number of students playing baseball }}{\text{Total number of students}}[/tex]
P(B) = [tex]\frac{12}{30}[/tex]---------------------------(3)
Finding [tex]P(A \cap B)[/tex]
P(A) = [tex]\frac{\text { Number of students playing both games }}{\text{Total number of students}}[/tex]
P(A) = [tex]\frac{8}{30}[/tex]-----------------------------(4)
Now substituting (2), (3) , (4) in (1), we get
[tex]P(A \cup B)= \frac{19}{30} + \frac{12}{30} -\frac{8}{30} [/tex]
[tex]P(A \cup B)= \frac{31}{30} -\frac{8}{30} [/tex]
[tex]P(A \cup B)= \frac{23}{30}[/tex]

Step-by-step explanation:
Martha Alison and Scott buy 3.8 pounds of clay Martha used 1 /4 of the clay for a sculpture Scott used 2/5 of the remaining amount of clay to make a mug and Alison used 1.2 pounds of clay to make a bowl how many pounds of clay are they left with ?
They are left with 0.51 pounds of clay.
Step-by-step explanation:
Given,
Amount of clay bought = 3.8 pounds
Amount used by Martha = [tex]\frac{1}{4}\ of\ clay[/tex]
Amount used by Martha = [tex]\frac{1}{4}*3.8=0.95\ pounds[/tex]
Amount left after Martha's use= Total amount - amount used by Martha
Amount left = 3.8 - 0.95 = 2.85 pounds
Amount used by Scott = [tex]\frac{2}{5}\ of\ amount\ left[/tex]
Amount used by Scott = [tex]\frac{2}{5}*2.85=\frac{5.70}{5}[/tex]
Amount used by Scott = 1.14 pounds
Amount left after Scott's use = Amount left after Martha's - Amount used by Scott
Amount left after Scott's use = 2.85 - 1.14 = 1.71 pounds
Amount used by Alison = 1.2 pounds
Amount left = Amount left after Scott's use - Amount used by Alison
Amount left = 1.71 - 1.2 = 0.51 pounds
They are left with 0.51 pounds of clay.

M(4,2)
N(-1,-2)
The figure shows two quadratic graphs M and N. N is a translation of M such that
the point (-1,-2) on M is translated to the point (4,2) on N. The equation
of N is y=-(x - 2)2 +6.
(a) Find the equation of M.
(2 marks)
Answer:
The equation of M is [tex]y=-(x+3)^2+6[/tex]
Step-by-step explanation:
we have that
The translation of M to N is
(-1,2) ----> (4,2)
The rule of the translation M to N is
(-1,2) ----> (x+a,y+b)
(-1,2) ----> (-1+a,2+b)
so
[tex]-1+a=4[/tex] ----> [tex]a=4+1=5[/tex]
[tex]2+b=2[/tex] ----> [tex]b=0[/tex]
The rule of the translation M to N is
(x,y) ----> (x+5,y)
The translation is 5 units right
I can say that the rule of the translation N to M is
(x,y) ----> (x-5,y)
we have the equation of N
[tex]y=-(x-2)^2+6[/tex]
Is a quadratic equation open downward
The vertex is (2,6)
Find the vertex of M
Applying the rule of the translation N to M to the vertex
(2,6) ----> (2-5,6)
(2,6) ----> (-3,6)
therefore
The equation of M is
[tex]y=-(x+3)^2+6[/tex]

$10.50
$23.50
Part A
Write a number in each blank to complete an inequality Lydia can use to find how
many pounds of Pumpkin Spice coffee, p, she can buy along with 2 pounds of
Dark Roast coffee.
Answer:
[tex]10.50p+15\leq 65[/tex]
[tex]p\leq \frac{100}{21}[/tex]
Step-by-step explanation:
Let p represent pounds of Pumpkin Spice coffee.
We have been given that Lydia is at a coffee shop and knows she can spend no more than $65 before tax. She sees this price list in the coffee shop.
Item Price per pound
Dark Roast Coffee $7.50
Pumpkin Spice Coffee $10.50
Breakfast Tea $23.50
Lydia wants to buy 2 pounds of Dark Roast coffee, so the cost of 2 pounds of Dark Roast coffee would be [tex]\$7.50\times 2=\$15[/tex].
We are told that cost of each pound of Pumpkin Spice coffee is $10.50, so cost of 'p' pounds of Pumpkin Spice coffee would be [tex]10.50p[/tex].
Since Lydia can spend no more than $65 before tax, so the cost of 2 pounds of Dark Roast coffee and 'p' pounds of Pumpkin Spice coffee must be less than or equal to 65.
We can represent this information in an inequality as:
[tex]10.50p+15\leq 65[/tex]
Therefore, our required inequality would be [tex]10.50p+15\leq 65[/tex].
[tex]10.50p+15-15\leq 65-15[/tex]
[tex]10.50p\leq 50[/tex]
Divide both sides by 10.50:
[tex]\frac{10.50p}{10.50}\leq \frac{50}{10.50}[/tex]
[tex]p\leq \frac{50*2}{10.50*2}[/tex]
[tex]p\leq \frac{100}{21}[/tex]
[tex]p\leq 4.76190[/tex]
Therefore, Lydia can buy less than or equal to [tex]\frac{100}{21}[/tex] pounds of Pumpkin Spice coffee.

[tex](8^{\frac{2}{3} } )^{4} = 256[/tex]
Step-by-step explanation:
Given
[tex](8^{\frac{2}{3} } )^{4}[/tex]
Required
Simplify
To simplify this, we apply law of indices but first we start by solving the expression in bracket.
8 =2 * 2 * 2
8 = 2³
So, we substitute 2³ for 8
[tex](8^{\frac{2}{3} } )^{4}[/tex] becomes
[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex]
From law of indices
[tex]a^{n} = (a^{m})^{\frac{n}{m} }[/tex] ==> [tex](a^{m})^{\frac{n}{m} } = a^{n}[/tex]
So, [tex](2^{3})^{\frac{2}{3} } = 2^{2}[/tex]
At this point we have
[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex] = [tex](2^{2})^{4}[/tex]
Also, from law of indices
[tex](a^{m})^{n} = a^{m.n}[/tex]
So,
[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex] = [tex](2^{2})^{4}[/tex]
[tex](2^{2})^{4} = 2^{2*4}[/tex]
[tex](2^{2})^{4} = 2^{8}[/tex]
[tex](2^{2})^{4} = 256[/tex]
Hence,
[tex](8^{\frac{2}{3} } )^{4} = 256[/tex]

find the range of the function below if the domain is {-1,0,2}
f(x)=x^2 -2x +3
Answer:
{3, 6}
Step-by-step explanation:
f(x) is the same thing as y. f(x) or y are the values that are shown in the range.
The domain represents all possible values of x. Data must be in an (x, y) form, where any value of "y" would need a partner, "x".
Substitute all of the possible x-values into the formula to find all possible y-values (the range).
f(x) = x² - 2x + 3
f(-1) = (-1)² - 2(-1) + 3
f(-1) = 1 + 2 + 3
f(-1) = 6
f(x) = x² - 2x + 3
f(0) = (0)² - 2(0) + 3
f(0) = 0 - 0 + 3
f(0) = 3
f(x) = x² - 2x + 3
f(2) = (2)² - 2(2) + 3
f(2) = 4 - 4 + 3
f(2) = 3 Do not write repeated numbers
The possible y-values are 3 and 6.
Writ the range in set notation in the brackets {}. Order the numbers from least to greatest.
Range is {3, 6}.
The range of a function with a specified domain is equal to {3, 6}.
Range of the function:
The function is f(x) = x² - 2x + 3. Given the domain {-1, 0, 2}, we can find the corresponding range by evaluating the function at each point in the domain:
For x = -1: f(-1) = (-1)² - 2(-1) + 3 = 6.
For x = 0: f(0) = 0² - 2(0) + 3 = 3.
For x = 2: f(2) = 2² - 2(2) + 3 = 3.
The range of this function for the given domain is {3, 6}.

Step-by-step explanation:
(4x+8)(x+3)=4x^2+8x+12x+24=4x^2+20x+24
The value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
We have two functions -
f(x) = 4x + 8
g(x) = x + 3
We have to determine f(x)*g(x).
What is function in mathematics ?A function in mathematics is an expression with a independent variable (x) in it. The variable is called independent because it is not dependent on any value to get its value. Function also has a dependent variable (y) whose value depend on x. Ex -
y = f(x) = ax + d
According to the question, we have -
f(x) = 4x + 8
g(x) = x + 3
Therefore -
f(x) * g(x) = (4x + 8)(x + 3) = 4x(x + 3) + 8(x + 3) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
Hence, the value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
