D. About 122 units I just took the test
Answer:
-1
Step-by-step explanation:
Since there are 300 students you have to use proportions to solve the percents. First for strawberry you need to set up a proportion such as x/300=30/100 to show you are trying to find 30%of 300. Then you must cross multiply so 300 times 30 and 100 times x. Then you have 9,000 and 100, so you divide 9,000 by 100 and then you get 90 which is the portion of kids who liked strawberry flavored ice cream. You should do the exact same thing for vanilla ice cream like this: x/300=29/100 but since you’re finding 29% you need to put a 29 over 100. Then you cross multiply and do 300 times 29 and do x times 100. Which makes you get 8,700 and 100, and then you divide 8,700 by 100 and get 87 for vanilla ice cream. Lastly you need to subtract 87 from 90 since it asked how many more students liked strawberry than vanilla: 90-87=
Can you please mark branliest? Thank you!
Answer:
Example 0-30 in 0-5 5-10 10-15 etc... upto 25-30
a) 12 and 15 or 10 and 15
b) none
c) none
a) Confidence Level Margin of Error Error Bar
68.3%, sx 12.2857 ±2.275 (±18.52%)
so a0 could be also 12.2857 - 2.275 = 10
Answer therefore may be 10 and 15
So try do a histogram go in 10's across 1-10,10-20,20-30,30-40,40-50
And if mean is 43 then you would need to multiply everything inside box by 0.3 before you can start the y axes
questions like this start with 0 - 50
