The expression [tex]\(4^5/3\)[/tex] is indeed equivalent to[tex]\(\sqrt[3]{4^5}\)[/tex].
The correct option is (a).
To demonstrate that the expression[tex]\(4^5/3\) is equivalent to \(\sqrt[3]{4^5}\)[/tex], we can apply the following properties:
1. Radical to Exponent Property:
- The expression [tex]\(\sqrt[3]{4^5}\) can be rewritten as \(4^{5/3}\)[/tex].
- This property allows us to convert a radical expression to an exponent expression by raising the base to the reciprocal of the index of the radical.
2. Exponent to Radical Change Property:
- The fraction exponent [tex]\(5/3\)[/tex] can be expressed as a radical: [tex]\(\sqrt[3]{4^5}\)[/tex].
down step-by-step:
1. Start with the given expression: [tex]\(4^5/3\)[/tex].
2. Apply the **Radical to Exponent Property: [tex]\[4^5/3 = 4^{5/3}\][/tex]
3. Now, express the fraction exponent as a radical:
[tex]\[4^{5/3} = \sqrt[3]{4^5}\][/tex]
Therefore, the expression [tex]\(4^5/3\)[/tex] is indeed equivalent to[tex]\(\sqrt[3]{4^5}\)[/tex].

The equation of a circle is given. What is the diameter of the circle? Round to the nearest tenth.
(x-2)2 + (y+3)2 = 52
Answers
Answer:
14.2 is the diameter.
Step-by-step explanation:
The radius squared = 52.
What you have given is the general equation of the circle with a center at (2,-3) and a radius of sqrt(52)
You can break the 52 down.
sqrt(52) = sqrt(4 * 13) = 2 sqrt(13). Notice that 4 is a perfect square.
d = 2*radius.
d = 2(2 sqrt(13) )
d = 4 sqrt(13)
That is the diameter. You want it to the nearest 1/10
d = 14.222 but it is to the nearest 1/10
d = 14.2

Get help: Video
Answers
Answer:
1. y=0.35x+35
2. If 979 minutes are used, the total cost will be $377.65 dollars.
Step-by-step explanation:
1. Let $x be the flat monthly fee and $y be the amount of money paid per minute used on the phone.
If a customer uses 210 minutes, the monthly cost will be $108.5, thus
[tex]x+210y=108.5[/tex]
If the customer uses 620 minutes, the monthly cost will be $252, then
[tex]x+620y=252[/tex]
Subtract from the second equation the first one:
[tex]x+620y-(x+210y)=252-108.5\\ \\x+620y-x-210y=143.5\\ \\410y=143.5\\ \\y=0.35[/tex]
Substitute it into the first equation
[tex]x+210\cdot 0.35=108.5\\ \\x=108.5-73.5\\ \\x=35[/tex]
We get the flat fee is $35 and the amount of money per minure used is $0.35. So, the equation of the function is
[tex]y=35+0.35x,[/tex]
where x is the number of monthly minutes used and y is the total monthly of the NextFell plan.
2. When x=979, then
[tex]y=35+0.35\cdot 979=377.65[/tex]

Probability of getting HH
Answers
Answer:
The experimental probability is 3% greater than the theoretical probability.
Step-by-step explanation:
We are given the results of flipping two coins with their outcomes and number of times they were tossed.
We are to compare the experimental and theoretical probability of getting HH.
The theoretical Outcomes are: HH HT TH TT
So theoretical probability of getting HH = [tex]\frac{1}{4} \times 100[/tex] = 25%
Total number of outcomes = [tex]28+22+34+16[/tex] = 100
So experimental probability of getting HH = [tex]\frac{28}{100} \times 100[/tex] = 28%
Therefore, the experimental probability is 3% greater than the theoretical probability.

Zoo tickets for 5 people cost a total of $41. Write an equation that can be used to determine the cost, c in dollars of each ticket
Answers
Answer:
Step-by-step explanation:
5t=41
The equation to determine the cost, c, of each zoo ticket when five zoo tickets cost a total of $41 is 'c = $41 / 5'.
Explanation:To find the cost of each zoo ticket, we need to divide the total cost of all the tickets by the number of people. Given that 5 people's zoo tickets cost a total of $41, we can set up the equation for this situation like this:
c = $41 / 5
Here, 'c' represents the cost of each zoo ticket in dollars. The equation suggests that when you divide the total cost ($41) by the total number of tickets (5), you get the cost of each individual ticket (c).

The longest river in the UK is the river Severn which has a length of 24 cm on a map. If the map is drawn at a scale of 1:1,500,000, then how many kilometers is the river actually?
Answers
Answer:
360 km
Step-by-step explanation:
we know that
The scale of the map is
1:1,500,000
That means
1 cm on a map ------> represent 1.500.000 cm in the actual
or
1 cm on a map ------> represent 15,000 m in the actual
or
1 cm on a map ------> represent 15 km in the actual
therefore
In this problem
24 cm on a map-------> represent 24*15=360 km actually
The actual length of the river Severn is 360 kilometers.
To determine the actual length of the river Severn, we need to apply the map scale to the map length. The scale given is 1:1,500,000, which means that 1 unit of measurement on the map corresponds to 1,500,000 of the same units in reality.
The map length of the river Severn is given as 24 cm. To find the actual length, we multiply the map length by the scale factor:
[tex]\[ \text{Actual length} = \text{Map length} \times \text{Scale factor} \] \[ \text{Actual length} = 24 \, \text{cm} \times 1,500,000 \][/tex]
Since the scale is in centimeters to kilometers, we need to convert the map length from centimeters to kilometers before multiplying by the scale factor. There are 100,000 centimeters in a kilometer, so:
[tex]\[ 24 \, \text{cm} = \frac{24}{100,000} \, \text{km} \] \[ 24 \, \text{cm} = 0.00024 \, \text{km} \][/tex]
Now, we multiply this by the scale factor:
[tex]\[ \text{Actual length} = 0.00024 \, \text{km} \times 1,500,000 \] \[ \text{Actual length} = 360 \, \text{km} \][/tex]
Therefore, the actual length of the river Severn is 360 kilometers.

Pocket contains 15 white eight pink three yellow and 10 blue golf balls. A ball is chosen at random, not replaced then another is chosen at random. What is the probability of blue, then pink
Answers
Answer:
4/63
Step-by-step explanation:
The probability of first choosing a blue golf ball and then a pink golf ball, without replacement, from the pocket is 4/63.
The question asks for the probability of selecting a blue golf ball and then a pink golf ball from a pocket that contains 15 white, 8 pink, 3 yellow, and 10 blue golf balls, without replacement. To solve this, we need to find the probabilities of each event happening sequentially and then multiply them.
Firstly, the probability of choosing a blue ball initially is 10 out of the total number of balls (15 white + 8 pink + 3 yellow + 10 blue), which gives us 36.
Therefore, the probability is 10/36 or 5/18. Once a blue ball has been chosen, it is not replaced, so the total count of balls is reduced by one, making it 35, and the count of blue balls is now 9.
Secondly, with the blue ball removed, we now calculate the probability of choosing a pink ball. There would still be 8 pink balls, so the probability of now choosing a pink ball is 8 out of the remaining 35 balls. This gives us the probability of 8/35.
To find the overall probability of both events happening in sequence (first a blue ball, then a pink ball), we multiply the individual probabilities: (5/18) × (8/35) = 40/630, which can be simplified to 4/63.

What is 50 percent of 62?
Answers
Answer:
31
Step-by-step explanation:
An entire amount is 100% of the amount.
50% is half of 100%, so 50% means the same as half.
Half of 62 is the same as 62/2 = 31
Answer: 31
Generally you would need to do a [tex]\frac{part}{whole}[/tex] proportion but there is a shorter way to do just the specific question. If you would like to know how to do the proportion version let me know
Since it asks for 50% of 62 it means that it's looking for half of 62, so all you have to do is divide 62 by 2 which is...
62/2 = 31
31 is 50% of 62

What is the solution to -41-2x + 61 = -24?

Step-by-step explanation:
Anyone of the values of x satisfies the equation. We can see it even calculating with basic math. If x is 0, then -41 -2(0) + 61 = -24
-41 +61 =-24
20 = -24 is incorrect
If x is -6, then -41 -2(-6) =-24
-41+12=-24
-29 = -24 incorrect.
If x is 6, then -41-2(6) + 61 = -24
-41-12+61 = -24
-53 + 61 = -24
8 = -24 is incorrect.
So it has no solution.

solve the equation 2y²=13y
Answers
Step-by-step explanation:
2y² = 13y
2y² − 13y = 0
y (2y − 13) = 0
y = 0, y = 13/2
It can be tempting to divide by y at the beginning, but if you do, you lose one of the solutions. Instead, move everything to one side and factor.
The solutions to the equation 2y²=13y are y = 0 and y = 6.5. This is achieved by setting up the equation to zero, factoring it out and applying the zero product property.
Explanation:To solve the provided equation, 2y²=13y, you'll need to set the equation to zero by moving all the terms to one side: 2y² - 13y = 0. This becomes a quadratic equation in the form ax² + bx + c = 0.
Factor the equation by taking out a common factor of 'y', yielding y(2y - 13) = 0. According to the zero product property, if a product is zero then at least one of the factors must be zero. This means that y = 0 or 2y - 13 = 0. Solving the second equation gives y = 6.5.
So, the solutions of the equation are y = 0 and y = 6.5.

Use the table from a random survey about the preferred service for streaming movies. Out of 750 people, how many would you expect to prefer Company B?
Answers
Answer:
The correct answer option is 192.
Step-by-step explanation:
We are given the results of a random survey about the preferred service for streaming movies.
We are to find the number of people we would expect to prefer Company B.
Number of people using service B = 32
Total number of people = 125
Number of people expected to prefer Company B = [tex] \frac{32}{125} \times 7 5 0 [/tex] = 192
Answer: Option A
192 people[
Step-by-step explanation:
From the participation survey
[tex]n =75+32+18=125[/tex] people
Among these 125 people, only 32 preferred the company B
Now assuming that this sample is representative of the total population, then the probability that a randomly selected person prefers company B is:
[tex]P =\frac{X_B}{n}[/tex]
Where
[tex]X_B=32[/tex]
[tex]n=125[/tex]
[tex]P =\frac{32}{125}[/tex]
[tex]P =0.256[/tex]
Finally, the expected number of people who prefer company B is:
[tex]E = P * m[/tex]
Where m is the number of people in the total population. [tex]m = 750[/tex]
[tex]E=0.256*750[/tex]
[tex]E=192\ people[/tex]
