Which of the following values is the 25th percentile?lower quartile, median, upper quartile

The required perimeter of the square is 48 units as of the given condition.

Given that,
The perimeter of a square with a side length of 5x -8 and a bottom length of 3x of a square is to be determined.

Perimeter is the measure of the figure on its circumference.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The length of all sides of the square is always remains equal,
5x - 8 = 3x
2x = 8
x = 4
Side length,
3x = 3(4) = 12
Now,
The perimeter of the square is 4-time sides,
Perimeter = 4 (12)

Perimeter = 48 units.

Thus, the required perimeter of the square is 48 units as of the given condition.

To evaluate the function f(x) = 4x - 1 for x=-1, you first substitute -1 into the equation, then perform multiplication before subtraction as per the order of operations resulting in f(-1) = -5.

To evaluate the function f(x) = 4x - 1 when x is -1, we simply replace the variable x in the equation with -1. The equation becomes f(-1) = 4(-1) - 1.

Now to perform the operations indicated in the equation, we should start with multiplication before subtraction according to the order of operations.

The multiplication of 4 and -1 gives -4 so the equation becomes f(-1) = -4 - 1.

Finally subtracting 1 from -4 gives -5. Therefore, f(-1) = -5.

Answer:

Carmen's prediction is low because 200 times  is 50.

Step-by-step explanation:

First of all we are going to define the sample space for this exercise.

The sample space is Ω = {1,2,3,4,5,6,7,8}

Given the event A : ''Roll an 8-sided die an get a multiple of 4''

The probability for the event A is

Because they are two numbers (4 and 8) over a total of eight numbers (1,2,3,4,5,6,7,8) that are multiple of 4.

Now, given the random variable X : ''Total of numbers multiples of 4 If she rolls

an 8-sided die 200 times''

X can be modeled as a Binomial random variable.

X ~ Bi (n,p)

X ~ Bi (200,)

In which n is the total times she rolls the 8-sided die and p is the success probability. We define a success as obtain a number multiple of 4.

The mean for this variable is

We answer that Carmen's prediction is low because 200 times  is 50.

Iliana was part of a group that was working on changing 0.4 repeated to a fraction. The answer is 2.25.

Percentage counts the number compared to 100.

So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get:

For each 1, there are a/100 parts.

Iliana was part of a group that was working on changing 0.4 repeated to a fraction.

Each member of the group had a different answer.

Let x be 0.444444[tex]\bar 4[/tex]

So,

4 / 10 = 0.4

4 / 9 = 0.4444444...

9/ 4 = 2.25

Answer:

1

Step-by-step explanation:

There are a total of 16+25 = 41 students that own hamsters.

There are a total of 16+24 = 40 students that own dogs.

This is a difference of 41-40 = 1.

Answer: 1

Step-by-step explanation:

Total number of students that own hamsters 16+25 = 41.

Total of students that own dogs 16+24 = 40.

To get how many more students own hamsters than dogs, we find the difference;

That is 41-40 = 1.

Good luck

To calculate the percentage of dogs with a weight between 47.7 lbs and 54.9 lbs, we need to use the properties of the normal distribution. We can expect that around 82.7% of Mark's dogs would have a weight within this range.

To calculate the percentage of dogs with a weight between 47.7 lbs and 54.9 lbs, we need to use the properties of the normal distribution. We know that the mean weight is 52.5 lbs and the standard deviation is 2.4 lbs.

First, we need to standardize the lower and upper bounds of the weight range using the formula: z = (x - mean) / standard deviation. For the lower bound, z = (47.7 - 52.5) / 2.4 = -1.96. For the upper bound, z = (54.9 - 52.5) / 2.4 = 1.

Next, we can use a standard normal distribution table or calculator to find the percentage of values between -1.96 and 1. The percentage is approximately 82.7%. Therefore, we can expect that around 82.7% of Mark's dogs would have a weight between 47.7 lbs and 54.9 lbs.

Using the normal distribution, calculations of z-scores, and a z-table to determine probabilities, we can expect approximately 81.85% of Mark's Siberian Husky sled dogs to weigh between 47.7 lbs and 54.9 lbs.

To determine the percentage of Mark's Siberian Husky sled dogs that weigh between 47.7 lbs and 54.9 lbs, we need to use the properties of the normal distribution. The mean weight of the dogs is 52.5 lbs and the standard deviation is 2.4 lbs. We can calculate the z-scores for 47.7 lbs and 54.9 lbs:

Z = (X - μ) / σ

For 47.7 lbs:

Z1 = (47.7 - 52.5) / 2.4 ≈ -2.0

For 54.9 lbs:

Z2 = (54.9 - 52.5) / 2.4 ≈ 1.0

Using a z-table or a statistical software, we can find the probabilities corresponding to these z-scores. The probability between Z1 and Z2 is the area under the curve in this range.

The probabilities associated with the z-scores are approximately 2.28% for Z1 (< -2.0) and 84.13% for Z2 (< 1.0). To find the percentage between Z1 and Z2, we subtract the smaller percentage from the larger one:

Percentage between 47.7 lbs and 54.9 lbs = 84.13% - 2.28% = 81.85%

Thus, we would expect that 81.85% of Mark's dogs have a weight between 47.7 lbs and 54.9 lbs.

A is correct

Step-by-step explanation:

Given: Table of x and y

 x  :  2    4     6     8

 y  :  3    4     5     6

Using two point find the slope:

(2,3) and (4,4)

[tex]Slope=\dfrac{4-3}{4-2}[/tex]

[tex]\text{Slope }=\dfrac{1}{2}[/tex]

Now we find slope using last two point

[tex]\text{Slope }=\dfrac{1}{2}[/tex]

Slope is equal. Thus, The given relation is linear.

Answer: Writting the equation and solving it, the answer is option D) .08c = .05c + 7.50; c = 250

Solution:

If the number of photocopies is c

Plan 1: Customers can pay $0.08 per page

The cost with plan 1 is: C1=0.08c

Plan 2: Customers can pay $7.50 for a discount card that lowers the cost to $0.05 per page.

The cost with plan 2 is: C2=7.50+0.05c

We want to find the number of photocopies for which the cost of each plan is the same, then we equal the cost of each plan:

C1=C2

Replacing C1 by 0.08c and C2 by 7.50+0.05c

0.08c=7.50+0.05c

Solving this equation for c: Subtracting 0.05c both sides of the equation:

0.08c-0.05c=7.50+0.05c-0.05c

Subtracting:

0.03c=7.50

Dividing both sides of the equation by 0.03

0.03c/0.03=7.50/0.03

c=250

Answer:

.08c = .05c + 7.50; c = 250

Answer:

The value of x is 10.

Step-by-step explanation:

Given information: STVU is an isosceles trapezoid, SV = 3x + 1 and TU = x + 21.

According to the properties of isosceles trapezoid, then diagonals of an isosceles trapezoid are equal.

SV and TU are diagonals of the isosceles trapezoid, so

[tex]SV=TU[/tex]

[tex]3x+1=x+21[/tex]

Separate like terms.

[tex]3x-x=21-1[/tex]

[tex]2x=20[/tex]

Divide both sides by 2.

[tex]x=10[/tex]

Therefore the value of x is 10.
