At Kirby Middle School, some students were surveyed to see which social
media app they used the most. The results are shown below.
App Number of Students
Face
8
Snap
22
Insta
20
Solve and explain how to calculate what percent of students used Snap the
most?

Answers

Answer:

Kirby Middle School

The percentage of students who used Snap the most is given as:

= 44%

Step-by-step explanation:

a) Data and Calculations:

App Number of Students

Face 8

Snap 22

Insta 20

Total 50

The percentage of Snap users = Number of Snap users/Total users * 100

= 22/50 * 100 = 44%

b) This represents the proportion of all the students surveyed about the use of social media app. Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap. This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.

The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?

Answers

Answer:

One number is 4.2, the other is 18.8

Step-by-step explanation:

1.) x+y=23

(x+6y)x2=4

2.) (x+6y)x2=4 = 2x+12y=4

3.)Use elimination/substitution to solve

2x+12y=4 = x+6y=2 = x=2-6y

2-6y+y=23

4.)Solve for y

2-5y=23 -> -5y=21 -> y=4.2.

5.)Solve for x

x+4.2=23

x=18.8

a) What type of correlation is shown in diagram A?
b) What type of correlation is shown in diagram B?
c) What type of correlation is shown in diagram C?

Answers

Answer:

A = strong negative correlation

B = positive correlation

C = very weak or no correlation

Step-by-step explanation:

Scatter plot A:

A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.

Scatter plot B :

Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.

Scatter plot C :

From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.

How many 1/9's in 31

Answers

There are a total of 279 1/9s in 31.

What is simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

To find out how many 1/9's are in 31, you can divide 31 by 1/9.

This can be simplified by converting the division of a fraction to multiplication with its reciprocal:

31 ÷ (1/9) = 31 × (9/1)

Simplifying the expression on the right side gives:

31 × 9 = 279

So there are 279, 1/9's in 31.
