What are ratio and proportion?

A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls) One-quarter are boys, and three-quarters are girls.

If for every $14 he earns $5.

Then on Saturday, he earned $70 so the total amount of money he would have

                         = 5 * 70/14

                         = 5 * 5

                         = $25

Hence, if Rob earned $70 then he would have $25.

The correct answer is at the univariate level, descriptive statistics are used for 'data reduction'

By creating the summaries of data samples, descriptive statistics can be used to describe the characteristics of a data set.

It is frequently presented as a summary of data that explains the contents of data. For instance, a census of the population may contain descriptive data on the proportion of men and women in a particular city.

Informational and intended to describe the precise features of a data set, descriptive statistics provide details. The greatest individual batting average for a player, the average number of runs per division, and the number of runs allowed per team are some descriptive statistics that may be used to analyse data from the previous Major League Baseball season.

The total time would be 38,3 seconds moves of arc length of 24.0 cm

The measurement of a circle's boundaries is also known as the circumference or the perimeter of the circle. whereas the circumference of a circle shows the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units such as cm or m are used to measure it.

First we convert cm to meters.

6.00cm= 0.006m

The length of the rectangular garden is 9 feet.

Let x = length of the rectangular garden in feet

y = width of the rectangular garden in feet

If a client asked Leah to design a rectangular garden with a length that is two feet less than three times the width, then

x = 3y - 2     (equation 1)

If the rectangular garden is to have an area of 33 square feet, then the product of the length and width should be equal to 33 square feet.

A = l x w

33 = xy

Substitute the expression for x and solve for y.

33 = xy

33 = (3y - 2)y

33 = 3y² - 2y

3y² - 2y - 33 = 0

(3y - 11)(y + 3) = 0

3y - 11 = 0     ;     y + 3 = 0

3y = 11     ;     y = -3

y = 11/3

If there are 13 packing boxes, how many cartons of ice cream are there in total?

192 packs of frozen peas were packed into 8 boxes.

How many were packed into each box?"

Answer:

The volumes are equal.

Step-by-step explanation:

Volume of cylinder = (area of base) × height

Volume of prism = (cross-sectional area) × height

Since the cross-sectional area are equal, and the heights are equal, the volumes are equal.

As we know that;

A person's net income, which differs from their gross income since it takes payroll deductions into account, is how much money they really take home from each paycheck. A person's net salary is the amount they earn after all necessary deductions, such taxes, have been made from their gross remuneration. After all deductions have been made, this is the total amount that is put into the employee's bank account. The amount an employee receives before any payroll deductions, including those for taxes, benefits, and other costs, is known as their gross pay.

Given:

b = growth rate

t = days

we are asked to find out after how many hours will the bacteria population reach 15000 = ?

P(t) = P0·bt

At t = 1 day, P(t=1) = 15,000:

15,000 = 10,000·b1

15,000/10,000 = b

1.5 = b

P(t) = 10,000·1.5t

Population doubles when P(t) = 20,000:

20,000 = 10,000·1.5t

2 = 1.5t

log(2) = log(1.5t)

log(2) = t·log(1.5)    [Log property: log(ab) = b·log(a)]

The binary search tree is better than the sorted link with respect to efficiency and intricacy.

Comparing a sorted linked list to a binary search tree for up to 1000 integer members, the intricacy of the algorithm in the sorted linked list grows over time. It differs depending on where the seeking element is located in sorted links. It requires little time if the searching element is present at the beginning of the linked list. However, in a linked list, the worst-case scenario occurs if the seeking element is present at 1000. Searching for the element in that position takes a long time.

The 1000 elements in a binary search split into two main wings. This type of search varies in difficulty depending on tree height. In the worst situation, if there are about equal numbers of elements on the left and right sides of the wing, searching for an element takes about half as long as searching for it in sorted links. Binary is more effective than Sorted as it uses a binary search algorithm instead of the linear search technique used by linked lists.

What is simple interest ?

The principal of a loan or the initial deposit into a savings account serves as the foundation for simple interest. Simple interest does not compound, therefore the creditor only has to pay interest on the capital sum and the borrower never has to pay interest on the interest that has already accrued.

Simple Interest formula

The given values are

I = 50000

P = 50000
