Complete the two-way frequency table below, which shows the relationship between students who enroll in advanced algebra and physics in a particular high school. From a sample of 40 students, it is found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both. How many students are enrolled in either algebra or physics?

Awnsers:
33

38

5

Answers

Answer 1

1. The frequency table will be:

Physics - Not in algebra = 9

Not in physics (Algebra) = 24

Not in physics (Not in algebra) = 2

Total (Not in physics) = 26

Total = 11

2. The students are enrolled in either algebra or physics is B. 38.

How to calculate the value?

It was found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both.

Not in physics for algebra = 24

Not in physics = 2

The Total for the value will be:

= 24 + 2= 26

The students enrolled in either will be:

= Algebra + Physics - Both

= 29 + 14 - 5

= 43 - 5

= 38

This illustrates the concept of addition and subtraction of numbers.

The larger of two numbers is 1 more than 3 times the smaller. Their sum is 65. Find the numbers.

Answers

The larger number is 49 and the smaller number is 16.

What are the numbers?

The first step is to form a linear expression that represents the larger number.

Let the smaller number be represented with y

The larger number is represented with this linear expression : 1 + 3y

The sum of the two numbers : 1 + 3y + y = 65

Take the following steps to determine the value of the smaller number:

Combine similar terms: 65 - 1 = 3y + y

Add similar terms together: 64 = 4y

Divide both sides by 4: y = 64 / 4

y = 16

Larger number = 1 + 3(16)

1 + 48 = 49

A water treatment plant needs to maintain the ph of the water in the reservoir at a certain level. To monitor this, they take 2 oz. Of water at 37 locations every hour, measure the ph at each of those locations, and find their average. If the ph level of the reservoir is ok, the results at each location will have varying results, with an average ph of 8. 5 and a standard deviation of 0. 22. If the ph level of the reservoir is ok, what is the probability that the sample average is less than 8. 42?.

Answers

P(X < 8.4)

= P(Z < (8.4 - 8.5) / (0.22 / sqrt(37)))

Answers

If x=lyl with inputs x = 1, x = 2, and x = 3 then y = ±1, y = ±2, and y = ±3.

To solve this problem we have to learn about the modulus operator and absolute value.

What is absolute value?

Absolute value is the distance of a number from zero.

Example: for -12, the distance from 0 is 12. Therefore 12 is the absolute value of -12.

What is the mod operator?

A Mod operator is a mathematical device that converts all types of integers into a positive integer or it finds the absolute value.

Now, we have to find values.

x=lyl Or, 1 = |y| or, we can say the absolute value of y is 1. y may be ±1x=lyl Or, 2 = |y| or, we can say the absolute value of y is 2. y may be ±2x=lyl Or, 3 = |y| or, we can say the absolute value of y is 3. y may be ±3

About Right triangle's

The formula for a right triangle's area, perimeter, and hypotenuse length are all included in the formula for a right triangle.

In geometry, there are several figure kinds that are distinguished from one another by their unique characteristics. A triangle is one of the shapes they frequently use. A triangle is a closed, three-sided polygonal shape. It has three vertices and three sides that contain the triangle's three interior angles. A triangle's three inner angles always add up to 180 degrees.

Equilateral, isosceles, scalene and right-angled triangles are the most typical triangle types we examine. The right triangle formula, commonly known as the right-angled triangle formulae, will be discussed in this section.

Any interior angle that is 90 degrees in length is said to be in a right triangle. It should be remembered that only one of the three angles may be a right angle because the total interior angle of a triangle is 180 degrees.

Continue reading: Right Angle Triangle

The triangle is referred to as an isosceles right-angled triangle if the other two angles are equal, or 45 degrees each. A scalene right-angled triangle, on the other hand, results from the other two angles being uneven.

Trigonometry is where right-angled triangles are used the most frequently. In reality, trigonometry's foundation is the relationship between its angles and sides.

What is average rate of change?

The average rate of change is a typical indicator of change over a period of time given in a function. It is equal to the difference between the function's input and output as a whole. It is a measurement of the average amount of change in the function per unit throughout that time. On the graph of the function, it is calculated from the slope of the straight line joining the interval's ends.

a high school has 48 players on the football team. the summary of the players' weights is given in the box plot. approximately, what is the percentage of players weighing greater than or equal to 232 pounds?

Answers

The proportion of players weighing more than or equatable to 220 pounds is 50%.

What is termed as the quartile?The dataset is divided into four groups by dividing the data into three points: lower quartile, midpoint, and upper quartile.The quartiles, along with the data set's minimum and maximum values, divide a collection of observations in to the four sections, each chosen to represent 25% of the observations.

Based on the information provided

There are 48 players in total.

Based on the box plot;

158 pounds is the minimum weight.

Q1 = 185, which represents 25% of the information below 185 pounds.

The second quartile Q2 = 220 pounds, which represents 50% of the information below 220 pounds.

The third quartile (Q3) = 232, representing 75% of the information below 232 pounds.

248 pounds is the maximum weight.

In this case, 220 is the middle number and represents the median.

50% of the information are located on both the left and right sides of the median.

As a result, the proportion of players weighing more than or equatable to 220 pounds is 50%.
