Carlos needs to memorize words on a vocabulary list for French class. He has memorized 30 of the words, which is three-fifths of the list. How many words are on the list?

Answers

Answer 1
Answer: a neat trick for this problem is that you can easily multiply 3 by a number to make it 30. (3x10=30). using the same number, multiply it by the denominator. 5x10=50. the answer is 50 (3/5 x 10/10 = 30/50 without changing the original ratio)

What is the simplest form of the expression (–11.7y – 3.3x) + 1.2x + (5.2y + x)? –16.9y – 5.5x –16.9y – 4.5x –6.5y – 2.1x –6.5y – 1.1x

Answers

Answer:

(D)-6.5y-1.1x

Step-by-step explanation:

The given expression is:

(-11.7y-3.3x)+1.2x+(5.2y+x)

Upon simplifying the above equation, we get

-11.7y-3.3x+1.2x+5.2y+x

Rewriting the above expression by writing the like terms together, we have

-11.7y+5.2y-3.3x+1.2x+x

Solving the like terms, we get

-6.5y-1.1x

which is the required simplified form of the given expression..

Hence, option (D) is correct.

D

Need help with middle two questions... I’ll give points

Answers

Answer:

ok sorry i could not put this into a formula im have to go but i will show you a really easy way.

Step-by-step explanation:

for number 1 i got (7,-1)

This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.

The correct way for doing number 1 is using the distance formula i believe but im running out of time

for the second one i got  (3, -1/2)

we do this by using the midpoint formula.

The first picture is for number one and the second for number 2

The number that appears most often in a given set of data is called the ______.

Answers

Answer:  Mode

For instance, the mode of the set {1,2,3,5,4,4,6,4,8,4,4,7,4} is 4 because it shows up the most compared to the other values. Making a frequency table can be helpful to determine the mode.

Final answer:

In statistics, the most recurring number in a data set is identified as the mode. It is calculated by identifying the frequency of each number in the data set. A data set may have one mode, no mode, or more than one mode.

Explanation:

The number that appears most often in a given set of data is called the mode. The mode is an important concept of statistics and helps in identifying the most frequent value in a data set. There can be more than one mode for a data set if they have the same frequency, which is the number of times a value appears in the data set. For example, in a data set of [2, 3, 3, 5, 5], both 3 and 5 are modes because they appeared twice each, which is more frequently than any other number in the data.

In some cases, the data set might have no mode when no number repeats or two modes, which will then be referred to as bimodal.

What is the converse of the following conditional?If a point is in the first quadrant, then its coordinates are positive

a. If a point is in the first quadrant, then its coordinates are positive
b. If the coordinates of a point are positive, then the point is in the first quadrant
c. If the coordinates of a point are not positive, then then the point is not in the first quadrant
d. If a point is not in the first quadrant, then the coordinates of the point are not positive.

Answers

The answer is B because the converse just flips the two phrases within the statement.

Answer:

b. If the coordinates of a point are positive, then the point is in the first quadrant

Answers

To solve for (1)/(2)- (1)/(10) You first need to find a common denominator.

To do so, you need to make both denominators 10 by multiplying the top and bottom of (1)/(2) by 5

(5)/(10)- (1)/(10)=(4)/(10)    Reduce by dividing both the top and bottom by 2

Your answer is (2)/(5)
The answer is 0.4 that is what i got
