Answer:
The cost of Jordan’s visits to the hair salon depends on the number of visits. The cost for 2 visits would be $60.00 (membership fee) + 2 * $26.00 (cost per visit) = $112.00. The cost for 4 visits would be $60.00 + 4 * $26.00 = $164.00. The cost for 5 visits would be $60.00 + 5 * $26.00 = $190.00. The cost for 8 visits would be $60.00 + 8 * $26.00 = $268.00.

Answer: 2 = 112 4 = 164 5 = 190 8 =268

Step-by-step explanation:

In order to solve this, the equation would be:

26x + 60

where x is the number of appointments, 26 is the amount each appointment costs, and 60 is the original price of the membership.

So...

2 visits would be $112

4 visits would be $164

5 visits would be $190

8 visits would be $268

Answer:

I can solve it, but you'll have to find out, because it's your homework, if it is an independent or dependent event:

9/(9 + 15 + 20)  -->  because we want to know chances of a red pen (qty 9)

9/(24 + 20)

9/44

0.2045454..., approx. 0.2045, or 20.45%

Answer: Hello!

Step-by-step explanation:

If no one can do it, I'll try.

This scenario is an example of dependent probabilities because the outcome of the second draw depends on what happened during the first draw. Specifically, if Joseph drew a red pen during the first draw, then there are fewer red pens remaining in the bag than before the first draw. As a result, the probability of drawing a red pen during the second draw decreases relative to the initial probability, assuming all pens were equally likely to be drawn initially. If the first pull didn't remove any pens from the bag, then the second pull is an independent event, and the probability remains unchanged.

In summary, whether the second event is independent or dependent depends on how many red pens remain in the bag after the first draw.

Where a number has three digits 6 8 and 1 to the nearest hundred the number rounds to 800 the number is 768.

In this case, the hundreds digit is 6, which means the number is between 600 and 699. The tens digit is 8, which is greater than 5, so we round up to the next hundred, which is 700. Therefore, the number is between 700 and 799.

We also know that when the number is rounded to the nearest hundred, it rounds to 800. This means the number is closer to 800 than to 700, and is at least 750. The ones digit is 1, which means the number is odd, and the sum of its digits is 6 + 8 + 1 = 15. This eliminates numbers that are multiples of 10 or have a sum of digits less than 15.

The only three-digit number that satisfies these conditions and rounds to 800 is 768. Therefore, the number is 768.

The possible numbers of hours the chemistry club could rent the meeting room is any value less than 8.

In inequality form:

t < 8

Let's begin by referring to the number of hours the chemical club rents the meeting space as "t".

The reservation charge plus the additional fee for the specified number of hours will equal the total cost to rent the meeting space:

Cost in total = $19 + $4.

The chemical club has stated that they want to pay less than $51 to rent the space:

Total cost < $51

Substituting the expression for total cost:

$19 + $4t < $51

Simplifying:

$4t < $32

Dividing both sides by 4:

t < 8

Therefore, the possible numbers of hours the chemistry club could rent the meeting room is any value less than 8.

To find the inverse of a function, we switch the x and y values. So the values representing the inverse of the function in the table above are: x: 4, 2, 1, 3, 4, and y: -2, -3, 6, 7, 5.

To determine if the inverse is a function, we need to check if each input value has only one output value.

Since the original function is a function, we know that each input value has only one output value.

When we switch the x and y values to find the inverse, we need to make sure that each y value only has one corresponding x value.

Looking at the values in the table, we can see that there are two different y values (4 and -2) that both have an x value of 5.

Therefore, the inverse is not a function.

The probability that a positive integer divisor of 12! is a perfect square can be expressed as 18/415. The sum of the numerator and denominator is 433.

We can start by finding the prime factorization of 12! which is

12! = 2¹⁰ × 3⁵ × 5² × 7 × 11

To find the number of divisors of 12!, we add 1 to each exponent and multiply them together:

Number of divisors = (10+1) × (5+1) × (2+1) × (1+1) × (1+1) = 3320

Now, we want to find the probability that a randomly chosen divisor of 12! is a perfect square.

A positive integer is a perfect square if and only if each of its prime factors has an even exponent.

Therefore, we need to count the number of divisors of 12! that have each prime factor with an even exponent.

For 2, there are 6 choices: 0, 2, 4, 6, 8, 10

For 3, there are 3 choices: 0, 2, 4

For 5, there are 2 choices: 0, 2

For 7, there are 2 choices: 0, 1

For 11, there are 2 choices: 0, 1

The total number of divisors of 12! that are perfect squares is the product of these choices

6 × 3 × 2 × 2 × 2 = 144

Therefore, the probability that a randomly chosen divisor of 12! is a perfect square is

P = 144/3320 = 18/415

The numerator and denominator have no common factors, so m=18 and n=415. Thus, m+n=433.

Answer: 50 degrees

Step-by-step explanation:

The margin of error is 2.695 for a sample size of 256 and a population variance of 484 at a 95% confidence level.



To find the margin of error, we need to use the formula:
Margin of error = z* (sigma / sqrt(n))
Where z* is the z-score corresponding to the desired confidence level, sigma is the population standard deviation, and n is the sample size.
In this case, we know that the population variance (sigma^2) is 484, which means the standard deviation (sigma) is sqrt(484) = 22.
The sample size (n) is 256.
The confidence level is 95%, which means the z-score is 1.96.
So, plugging these values into the formula, we get:
Margin of error = 1.96 * (22 / sqrt(256))
Simplifying, we get:
Margin of error = 1.96 * (22 / 16)
Margin of error = 2.695


Hence, we use the formula Margin of error = z* (sigma / sqrt(n)), where z* is the z-score corresponding to the desired confidence level, sigma is the population standard deviation, and n is the sample size. The margin of error is 2.695 for a sample size of 256 and a population variance of 484 at a 95% confidence level.

There will be 27 smaller cubes of length 5 cm each.

V = s^3, where s is the length of a side of the cube.

In this case, the length of the side of the original cube is 15 cm, so its volume is:

V = 15^3 = 3,375 cubic cm

When the cube is melted down and reformed into smaller cubes of 5 cm, the number of smaller cubes is equal to the total volume of the original cube divided by the volume of each smaller cube. The volume of each smaller cube is:

V = s^3 = 5^3 = 125 cubic cm

So, the number of smaller cubes is:

Number of smaller cubes = Total volume of original cube / Volume of each smaller cube

Number of smaller cubes = 3,375 / 125

Number of smaller cubes = 27

1 No, the table does not represent an exponential function.

2 The equation y = a² represents a parabolic function with a vertex at the origin (0,0).

1. An exponential function is a function of the form f(x) = a^x, where a is a constant greater than 0, and x is the input variable. In an exponential function, the output values (y) are the result of the input values (x) being raised to a constant power (a). In this case, the table does not represent an exponential function since there's no constant value.

However, in the given table, the values of y are not obtained by raising any constant to the power of x. Instead, the values of y are obtained by multiplying the previous value of y by a constant factor in each row. It's not a exponential Function.
