( i need a full explanation please :)
Students in school were asked what activity they like to do in gym class. The results are shown below.
( graph info below questions )
A - What percent of females picked volleyball?
B - What percent of males picked basketball?
C - What percent of the total number of students picked track?
GRAPH :
basketball ( f ) 23 ( m ) 30
volleyball 32 26
softball 16 12
track 18 21
totals - both 89
A. 35% girls picked volleyball.
B. 33% boys picked basketball
C. 43% students picked track.
can you show your work for that please math ?
for example
out of 89 girls
32 played volleyball
100(32/89) = 36
Total females = 23 + 32 +16 +18 = 89.
Total males = 30 + 26 + 12 + 21 = 89
Total students = 178.
A. 32/89 * 100% = 36%.
B. 30/89 * 100% =
C. (18+21)/178 * 100% =
.
To find the necessary percentages, we first need to calculate the total number of females and males who participated and the total number of students overall.
Given:
- Basketball: Females - 23, Males - 30
- Volleyball: Females - 32, Males - 26
- Softball: Females - 16, Males - 12
- Track: Females - 18, Males - 21
To find the total number of females, add up the number of females in each activity:
23 (basketball females) + 32 (volleyball females) + 16 (softball females) + 18 (track females) = 89 females
To find the total number of males, add up the number of males in each activity:
30 (basketball males) + 26 (volleyball males) + 12 (softball males) + 21 (track males) = 89 males
To find the total number of students: total females + total males = 89 (females) + 89 (males) = 178 students
Now, let's answer the questions:
A - What percent of females picked volleyball?
To find this percentage, divide the number of females who picked volleyball (32) by the total number of females (89), and then multiply by 100 to get the percentage:
(32 / 89) * 100 = 35.96%
Therefore, about 36% of females picked volleyball.
B - What percent of males picked basketball?
To find this percentage, divide the number of males who picked basketball (30) by the total number of males (89), and then multiply by 100 to get the percentage:
(30 / 89) * 100 = 33.71%
Therefore, about 34% of males picked basketball.
C - What percent of the total number of students picked track?
To find this percentage, add up the number of students who picked track (18 females + 21 males = 39), and then divide by the total number of students (178), and multiply by 100 to get the percentage:
(39 / 178) * 100 = 21.91%
Therefore, about 22% of the total number of students picked track.
