Answer:
42
Step-by-step explanation:
h(-6) = 41-5
h(-6) = 36
h = 36 + 6
h = 42
Answer: t = 6 s
Step-by-step explanation:
When Rose hit the water, the height of the jump is 0, so: h(t) = 0.
Resolving it, we have:
-16t² + 16t + 480 = 0
To simplify the second degree equation, divided it by 16:
-t² + t + 30 = 0
Now, solve the equation using Bhaskara:
Δ = 1² - 4. (-1) . 30
Δ = 1 + 120
Δ = 121
t = 
t₁ = 
= - 5
t₂ = 
= 6
Since time can be negative, it took t = 6s for Rose to hit the water.
Answer:
The percentage of Millennial students at his college who live in their parents' home is the same as the percentage of Millennials nationwide
Step-by-step explanation:
Given that a Pew Research analysis stated that in 2012, 36% of the nation's young adults ages 18-31 the so-called Millennial generation - were living in their parents' home.
After reading the analysis, a statistics student wanted to design a study to determine if the percentage was higher for the Millennial students who attend his college.
Hence proper hypotheses would be claiming p = 36% against p >36%
The percentage of Millennial students at his college who live in their parents' home is the same as the percentage of Millennials nationwide
Because null normally we give equal to against alternate.
447 is the distance between the numbers
