Which of the following are not polynomials? A.2/3x^-2+x+1 B.x^3+0x^2x+
Option A is not a polynomial because it contains a term with a negative exponent, while option B is a polynomial because all the terms have non-negative integer exponents.
A polynomial is a mathematical expression consisting of variables and coefficients, where the variables are raised to non-negative integer powers and are multiplied together. Polynomials are used to represent many different kinds of relationships in mathematics and are essential in areas such as algebra, calculus, and number theory.
In option A, the expression \(2/3x^{-2}+x+1\)is not a polynomial because it contains a term with a negative exponent. Any term in which a variable appears with a negative exponent is not a polynomial.
Negative exponents represent the inverse of a term raised to a positive exponent, and as such, they involve division, which is not allowed in polynomials. Therefore, the term \(2/3x^{-2\) makes the expression A not a polynomial.
In option B, the expression\(x^3+0x^2^x\) is a polynomial because all the terms have non-negative integer exponents. The expression can be simplified to\(x^3 + 0x^3\), which is equivalent to \(x^3.\)
The constant term \(0x^2\), which has a zero coefficient, does not affect the polynomial nature of the expression. The degree of the polynomial is 3, which is the highest power of the variable in the expression.

In order to fill his fish tank to capacity Jamal needs to put 25 gallons of water into the tank. If Jamal has 12.5% of the tank filled with water, how much more water does he need to put into the tank?
Answer:
\(21\frac{7}{8} \)
Step-by-step explanation:
\(12.5\% = \frac{1}{8} \)
\(25 \times \frac{1}{8} = \frac{25}{8} = 3 \frac{1}{8} \)
\(25 - 3 \frac{1}{8} = 24 \frac{8}{8} - 3 \frac{1}{8} =21\frac{7}{8} \)

Recall that the cigarette industry requires that models in cigarette ads must appear to be at least 25 years old. Also recall that a sample of 50 people is randomly selected at a shopping mall. Each person in the sample is shown a "typical cigarette ad" and is asked to estimate the age of the model in the ad. The p -value for testing H0 versus Ha can be calculated to be 0.0038.
Determine whether H0 would be rejected at each of ? = .10, ? = .05, ? = .01, and ? = .001. (Round your answer to 4 decimal places.)
p-value Reject H0 at ? =
The p-value for testing H0 (null hypothesis) versus Ha (alternative hypothesis) is 0.0038. We need to determine whether H0 would be rejected at different significance levels: α = 0.10, α = 0.05, α = 0.01, and α = 0.001.
To make the decision, we compare the p-value with the chosen significance level. If the p-value is less than or equal to the significance level, we reject H0. Otherwise, we fail to reject H0.
At α = 0.10: Since the p-value (0.0038) is less than 0.10, we reject H0.
At α = 0.05: Since the p-value (0.0038) is less than 0.05, we reject H0.
At α = 0.01: Since the p-value (0.0038) is greater than 0.01, we fail to reject H0.
At α = 0.001: Since the p-value (0.0038) is greater than 0.001, we fail to reject H0.
In summary:
H0 would be rejected at α = 0.10 and α = 0.05.
H0 would not be rejected at α = 0.01 and α = 0.001.
Please note that the decision to reject or fail to reject the null hypothesis depends on the chosen significance level, and different levels of significance can lead to different conclusions.

[2 marks] b) If she makes her various choices at random, what is the probability that she will take Morningside Drive, park in lot A, use the south entrance, and take elevator 1? [3 marks] c) As she starts her car one morning, she recalls parking lots A and B are closed for repair. What is the probability that she will take Industrial Avenue, park in lot D, use the north entrance, and take elevator 2?
Answer:
a) 72
b) 1/72
c) 1/36
Step-by-step explanation:
a) number of ways she can choose route= 3C1 = 3
number of ways she can choose parking lots= 4C1 = 4
number of ways she can choose entrances= 3C1 = 3
number of ways she can choose elevators= 2C1 = 2
number of ways she can go to office= number of ways she can choose route×number of ways she can choose parking lots×number of ways she can choose entrances×number of ways she can choose elevators
number of ways she can go to office= 3×4×3×2
= 72
b) Probability of morning side= number of morning side/ total number of routes= 1/3
probabiltiy of Parking lot A= number of parking lot A/ total number of parking lot= 1/4
probability of south entrance= number of south entrance/ total number of entrances= 1/3
probablity of elevator 1= number of elevator 1/ total number of elevator= 1/2
combine probability= 1/3× 1/4×1/3×1/2 = 1/72
c) Probability of Industrial Avenue= number of industrial avenue/ total number of avenue= 1/3
Probability of parking lot D= number of parking lot D/ total number of parking lot after deducting number of parking lots A and B = 1/2
Probability of north entrance= number of north entrance/ total number of entrance= 1/3
probablity of elevator 2= number of elevator 2/ total number of elevator
= 1/2
combine probability= 1/3 × 1/2 × 1/3 ×1/2
= 1/36

Sofia said, "I'm thinking of a fraction that is equivalent to 5 6 . The numerator is 4 less than the denominator." What fraction is Sophia thinking of?
Answer: 20/24
Step-by-step explanation:
Let the denominator be x
The numerator is 4 less than the denominator. Therefore, numerator = x-4.
We can then use the information given in the question as:
5/6 = x-4/x.
Cross multiply.
5 × x = 6(x-4)
5x = 6x - 24
6x - 5x = 24
x = 24
Since the denominator is 24, the numerator will be: = x - 4 = 24 - 4 = 20
Then, the fraction will be 20/24
The volume of a rectangular solid is 540 cubic feet.
The width is 3 feet more than the height, and the
length is 4 more feet than the height. Find the
dimensions of the solid.
Answer:
l = 32.57, w = 24.43, h = 8.14
Step-by-step explanation:
volume = l*w*h
l = 4x
w = 3x
h = x
540 = 4x * 3x * x
540 = 12x^3
\(\sqrt[3]{540}\) = 8.14
l = 4x = 4(8.14) = 32.57
w = 3x = 3(8.14) = 24.43
h = x = 8.14

a cycle shop gave away 5000 miniature cycles and bumper stickers. the cycles cost 0.62 each and the bumper stickers cost 0.52 each. the cycle shop spent $2798 on the gifts. how many of each gift did they buy>
The cycle shop gave away 1980 miniature cycles and 5000 - 1980 = 3020 bumper stickers.
Let's call the number of miniature cycles given away "x". The number of bumper stickers given away would then be 5000 - x.
The cost of the cycles is 0.62x, and the cost of the bumper stickers is 0.52 (5000 - x).
So we can write an equation to represent the total cost:
0.62x + 0.52 (5000 - x) = 2798
Expanding the second term:
0.62x + 2600 - 0.52x = 2798
Combining like terms:
0.10x = 198
Finally, solving for x:
x = 1980
So the cycle shop gave away 1980 miniature cycles and 5000 - 1980 = 3020 bumper stickers.
