The answers are shorter, higher, 2cm, 15cm, 20% and 15%.
Step-by-step explanation:
Step 1; From the given data Hugo measured his plant higher than its original height. Hugo measured his plant as 12 cm while it was actually 10 cm. So Hugo's measurement was off by 2cm. Hugo's percent error is given by dividing the difference in values by the actual value.= multiplied by 100.
% error = (difference in values / actual value) × 100
Hugo's % error = (12 - 10)/ 10 × 100 = 2/10 × 100 = 20%.
Step 2; Koby measured his plant lower than his plant's original height. He measured it to be 85 cm while it was 100 cm tall. So Koby's measurement was off by 15cm. The percent error is calculated in the same way.
% error = (difference in values / actual value) × 100
Koby's % error = (100 - 85)/ 100 × 100 = 15/100 × 100 = 15%.
Step 3; Hugo had a percent error of 20% while Koby has a percent error of 15%. So Hugo had a higher percent error of the two.
Answer:
s = 32
Step-by-step explanation:
–5(s – 30) = –10
Divide each side by -5
–5/ -5(s – 30) = –10/-5
s - 30 = 2
Add 30 to each side
s-30+30 = 2+30
s = 32
Answer:
Average annual tuition is $16991 for the year 2020.
Step-by-step explanation:
By using excel for the equation of the line of best fit,
Slope of the line from given data = 380.0286
y - intercept of the line = 11290.1
Therefore, equation of the regression line will be,
y = 380.0286x + 11290.1
Where x = number of years after 2005
Now we have to calculate the average annual tuition in the year 2020,
By substituting the value of x = 2020 - 2005
= 15 years
y = 380.0286×(15) + 11290.1
y = 16990.529
≈ 16991
Therefore, average annual tuition is $16991 for the year 2020.
Answer:
C.) go to a baseball game than watch it on television
Step-by-step explanation:
Only 7.9% of the 1200 people would rather watch a game on television than go to a game.

Step-by-step explanation:
Given that a librarian has a set of ten different books, including four different books about Abraham Lincoln.
The librarian wants to put the ten books on a shelf with the four Lincoln books next to each other, somewhere on the shelf among the other six different books.
First arrnage the 6 other books in the shelf.
This can be done in 
Now arrange the 4 books of Lincoln
This can be done in 
Now we have 7 places to insert Lincoln books including two corners and in between.
Thus this can be done in 7 ways
Total no of ways =
