Answer:
2250 trees
Step-by-step explanation:
Find how many eucalyptus trees are planted in an hour.
4 hours = 1000
1 hour = 1000 ÷ 4 = 250
20 pupils = 250
1 pupil = 250 ÷ 20 = 12.5 (in an hour)
30 pupils = 12.5 x 30 = 375 trees (in an hour)
6 hours = 375 x 6 = 2250 trees
Answer:
x = 2
Step-by-step explanation:
h(x) = f(x) + g(x) = x³ + 2x² + 1 - x³ - x² - 4x + 4 ← collect like terms, thus
h(x) = f(x) + g(x) = x² - 4x + 5
Given
h(x) = 1, then
x² - 4x + 5 = 1 ( subtract 1 from both sides )
x² - 4x + 4 = 0 ← in standard form
(x - 2)² = 0 ← in factored form ( perfect square ), thus
x - 2 = 0 ⇒ x = 2
6 is your answer.
With box and whisker plot, the first quartile is where the box starts. In this case it’s 6. The median of this set is 8, represented by the line inside the box. The third quartile is where the box ends, 11 in this case.
The whiskers show the lowest and highest numbers of the data set.
Hope this helped. LMK if you have questions.
