Answer=56 ounces
First lets find a conversion equation for pounds to ounces...
1pound=16ounces
9pounds=9*16=144ounces
3pounds=3*16=48ounces
Given the data, the following equation can be made, where x is equal to the weight of her science textbook.
144=48+40+x
144=88+x
subtract 88 from both sides
56ounces=x
The science textbook weighs 56ounces
Answer:the last one I’m not really sure
Answer:
79.31%
Step-by-step explanation:
First we need to find the total number of students.
We do that summing all the four values in the table:
Total students = 2 + 18 + 3 + 6 = 29
Then, the students that play a sport or an instrument are all student but the ones that don't play both:
Students(sport or instrument) = 29 - 6 = 23
So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%
