What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
A printing error in a math book removed the brackets and parentheses from a numerical expression.
The numerical expression is given below.
⇒ 32 + 7 x 4 + 5
Simplify the numerical expression, then we have
⇒ 32 + (7 x 4) + 5
⇒ 32 + 28 + 5
⇒ 65
The printing error in a math book will be given as,
⇒ 69 - 65

Tell whether the ratios form a proportion. 2 : 4/5, 3/4 : 3/10
Yes, they are in proportion as both the ratios equal to 5 : 2.
what is ratio and proportion?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given here first ratio as = 2 : 4/5
= 10 : 4
= 5 : 2
and the second ratio as = 3/4 : 3/10
= 1/4 : 1/10
=10 : 4
= 5 : 2
Hence both the ratio are equal and therefore in proportion.

Samples of size n= 240 are randomly selected from the population of numbers (O through 20)
produced by a random-number generator, and the variance is found for each sample. What is
the distribution of the sample variances?
normal (approximately)
skewed to the right
skewed to the left
not enough information provided
Based on the information provided, it is not possible to identify the distribution of the sample variances, and the correct answer is "not enough information provided.".
What is Sample Variance?The distribution of data points in a particular data collection around the mean is measured by sample variance. The population is the sum of all observations of a group. When the number of observations rises, calculating the population variance gets complicated.
It is not possible to determine the distribution of the sample variances based on the information provided. The distribution of the sample variances depends on the distribution of the population from which the samples are drawn. Without knowing the distribution of the population, it is not possible to determine the distribution of the sample variances.

So a triangle adds to 180 degrees, 96+48= 144
180-144=36
36 is the answer for the angle to the right of x
to find x you must find its coterminal angle (I think is the word, They have to add to 180)

The table below shows data from a survey about the amount of times students spend doing homework each week. The students were either in college or in high school:
Which of the choices below best describes how to measure the spread of this data?
A- Both spreads are best described with the IQR.
B- Both spreads are best described with the standard deviation.
C- The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
D- The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answer:
in table data from a survey about the amount of time students spend doing homework each week. The students were either in college or in high school: High Low Q1 Q3 IQR Median Mean σ
College 50 5 7.5 15 7.5 11 13.8 6.4
High School16 0 9.5 14.5 5 13 10.7 5.3 Both spreads are best described with the standard deviation.
Step-by-step explanation:
The true statement is that: (b) Both spreads are best described with the standard deviation.
OutliersTo determine the spread to use for the dataset, we start by checking for outliers using:
[tex]L = Q_1 - 1.5 \times IQR[/tex]
[tex]U = Q_3 + 1.5 \times IQR[/tex]
CollegeFor the college, we have:
[tex]L =8 - 1.5 \times 10 = -7[/tex]
[tex]U = 18 + 1.5 \times 10 = 33[/tex]
The range of the dataset is 6 to 20.
This means that, there is no outlier in the college dataset
High SchoolFor the high school, we have:
[tex]L =5.5 - 1.5 \times 10.5 = -10.25[/tex]
[tex]U = 16 + 1.5 \times 10.5 = 31.75[/tex]
The range of the dataset is 3 to 20.
This means that, there is no outlier in the college dataset
Since there are no outliers in both dataset, then it is best to use the standard deviation to describe the spread
Hence, both spreads are best described with the standard deviation.

Match each expression to the scenario it represents.

Using proportions, the amounts are given as follows:
18% off: 0.82x.18% more: 1.18x.Volume after [tex]\frac{3}{10}[/tex] is drained out: [tex]\frac{7x}{10}[/tex]New stock: [tex]\frac{13x}{10}[/tex]What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the amounts are found as follows:
18% off its list price (x), that is, 82% of x, hence 0.82x.Sells for 18% more, that is, 118% = 1.18 of x, hence 1.18x.When three tenths of the volume is drained out, the remainder is 100% = 1x subtracted from that, hence [tex]\frac{7x}{10}[/tex].For the new stock, three tenths of x plus the current stock of x, hence [tex]\frac{3}{10}x + x = \frac{13}{10}x[/tex].More can be learned about proportions at https://brainly.com/question/24372153
