A group of individuals were surveyed about their plans for vacation. There were 21 individuals who said they were going to the d
Alexeev081 [22]

Answer:

140 individuals were surveyed

42 people are planning on going to the mountains

Step-by-step explanation:

The question is missing the information regarding the percentage of people who said that they were going to each of the possible destinations. After a quick google search I've found that, in the original question, 32% of individuals were going to the beach, 15% to the desert, 23% to major cities, and 30% to the mountains.

If 21 people said they were going to the desert, and that corresponds to 15% of the total number of people surveyed, the number of people surveyed is:

21=n*0.15\\n=140\ individuals

140 individuals were surveyed

Since 30% responded "the mountains", the number of people planning on going to the mountains is:

m = 140*0.30\\m=42\ people

42 people are planning on going to the mountains

First do 12-5, which equals 7.  Next, subtract 1/10 from 2/5.  2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2.  4/10-1/10=3/10. Now add 7 and 3/10.  You will get 7 3/10 as the answer, which is letter C.)

In a survey of 120 8th graders, 84 liked math, 73 liked science and 23 liked math but not science. how many students disliked bo
hammer [34]
24  
We can divide the 8th graders into 4 groups. They are: 
1. Like both math and science. 
2. Like only math. 
3. Like only science. 
4. Don't like either math or science.  
The sum of the people in all 4 groups will add up to 120. So let's see how many are in each group. 
We've been given 23 as the number of people who like only math (group 2).
And since we know that 84 people like math, that means that 84 - 23 = 61 people are in group 1. And since we know that 73 people like science, that means that 73 - 61 = 12 are in group 3. So of the 4 groups, we now know. 
1. Like both math and science (61 people).
 2. Like only math (23 people).
 3. Like only science (12 people).
 4. Don't like either math or science (unknown).
 
 So for the people left in group 4 (don't like either subject) that will be 120 - 61 - 23 - 12 = 24.
