Answer:

Step-by-step explanation:

Let's say there are "x" students in class 6.

Since Anton got 0.2 of the votes, he got 0.2 * x votes.

Eva got 10% of the votes, which is equal to 0.1 * x votes.

Petra got 0.3 of the votes, which is equal to 0.3 * x votes.

Kofi got 9 votes.

So, the total number of votes in class 6 is x.

By adding up the number of votes each candidate received, we can write an equation:

0.2x + 0.1x + 0.3x + 9 = x

Simplifying the equation:

0.6x + 9 = x

Subtracting 0.6x from both sides:

9 = 0.4x

Dividing both sides by 0.4:

x = 22.5

Since the number of students must be a whole number, we round up to the nearest whole number:

x = 23

So there are 23 students in Class 6.

The total length of the bolt should be 21/8 inches.

The study and application of numbers in all other fields of mathematics are covered in the area of mathematics known as arithmetic operations. Addition, subtraction, multiplication, and division are included in the basic operations.

Given the thickness of plate 1 = 7/8 inches

the thickness of plate 2 = [tex]1\frac{1}{4}[/tex] inches = 5/8 inches

total thickness of both plates = 7/8 + 5/4

5/4 is equaivalent to (5*2)/(4*2) = 10/8

the total thickness of both plates = 7/8 + 10/8

the total thickness of both plates = 17/8 inches

and the bolt must be at least 1/2 inch longer

total length of bolt = 17/8 + 1/2

convert 1/2 to the same denominator as 17/8

1/2 = (1*4)/(2*4) = 4/8

total length of bolt = 17/8 + 4/8

the total length of the bolt =  21/8 inches

Hence the bolt should be 21/8 inches longer.

Answer:

- 8.5

Step-by-step explanation:

The value of the 25th percentile for this data set is 26.25. This means that 25% of the data is below 26.25 and 75% of the data is above 26.25

The 25th percentile, also known as the lower quartile, is a value that separates the lowest 25% of the data from the rest of the data. To find the 25th percentile of an ordered data set, we first need to determine the position of the 25th percentile, which can be calculated using the formula:

position = (n+1) * p

where n is the number of observations in the data set and p is the percentile (in decimal form). In this case, n = 8 and p = 0.25. Put values:

position = (8+1) * 0.25 = 2.25

Since the position is not a whole number, we know that the 25th percentile falls between the second and third observations in the data set. In this case, the second observation is 24 and the third observation is 27. To find the exact value of the 25th percentile, we use the formula:

value = L + (position - i) * h

where L is the value of the lower observation, i is the integer part of the position, and h is the difference between the two observations. In this case, L = 24, i = 2, and h = 27 - 24 = 3. Put values:

value = 24 + (2.25 - 2) * 3 = 24 + 0.75 * 3 = 24 + 2.25 = 26.25

Answer:

150 units (Option C)

Step-by-step explanation:

Perimeter of rectangle = Perimeter of triangle

= {2 × (Length + Width)} = Sum of all three sides

= {2 × [(2x) + (x + 12)]} = [(4x) + (2x) + (x + 3)]

The parenthesis are expanded using the Distributive Law:
= {2 × [2x + x + 12]}  = [4x + 2x + x + 3]

= {2 × [3x + 12]} = [7x + 3]
= 6x + 24 = 7x + 3

Bring all the like terms together and isolate x:

= 24 - 3 = 7x - 6x

= 21 = x

∴x = 21

Substitute this calculated value of x to determine the perimeter of rectangle:

6x + 24

Answer:

A(L) = - L²  + 215L

Domain
0 < L < 215

or

(0, 215) in interval notation

Step-by-step explanation:

Let  L represent the length and W the width

Perimeter of a rectangle = 2(L+W) and is given as 430 meters

Therefore 2(L + W) = 430

L + W = 430/2
L + W = 215

W = 215-L

The area A is given by L x W

Substituting for W in terms of L this becomes

A = L x(215 - L)

A = 215L - L²

which can be expressed as a function of in the form
A(L) = 215L - L² or in standard form(highest degree first)

A(L) = - L²  + 215L

The domain of this function are the values of L which result in a defined , real value for A

Without restrictions, the domain for L is -∞ < L < ∞. However real world facts coming into play

1. Area cannot be zero
So A(L) > 0 (upper bound on area)

-L² + 215L > 0

-L² > - 215L Move 215L to right side

L² < 215L   (dividing by -1 changes signs of variables and also inequality)

L < 215      (divide by L both sides)

2. Length cannot be negative
So lower bound on L is L > 0

Together the domain is
0 < L < 215

or

(0, 215) in interval notation

There are only real numbers in the domain, or collection of x-values. This is so because x holds true for all numbers. The set of all non-negative real numbers is known as the range or set of y-values. This is due to the fact that every value we obtain for y is a positive real number. The graph's x-intercept and y-intercept, also known as the intersection point, are located at (0, 0). Instead of the other way around, the graph increases on the interval x>0 and decreases on the interval x<0. Instead of a maximum, the graph shows a minimum at (0, 0). The graph is symmetric with respect to the y-axis because it may be folded in half along that axis.

As per the question, the function described below is an example of a polynomial function since it is a function of a single independent variable that has been raised to an integer power.

First off, the dice has twelve sides and only of the sides, 9, will allow a customer to win.

this means that there is a 1/12 chance that the customer will win a prize.

We can rewrite this into a decimal: 0.0833

and then to a percentage rounded to the nearest tenth: 8.3%

The probability that a customer wins a prize is 8.3% to the nearest tenth.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

A clothing store has each customer roll a 12-sided die with faces numbered 1−12 to win a free T-shirt.

Customers who roll a 9 win.

Total possible outcomes = 12

Number of outcomes which results in a win = 1

Probability that a customer wins = 1/12

                                                       = 0.08333

                                                       = 8.3%
