This is an incomplete question, here is a complete question.
A hurricane wind blows across a 7.00 m × 12.0 m flat roof at a speed of 150 km/h.
What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.
Answer : The pressure difference will be, 
Step-by-step explanation :
As we are given:
Speed = 150 km/h = 41.66 m/s
Density = 
Area = A = 7.00 m × 12.0 m
Formula used :
Now put all the given values in this formula, we get:
Thus, the pressure difference will be,
Answer:
Graph A.
Step-by-step explanation:
The X-Axis refers to strictly horizontal movement, so the farther right it moves, the lower the dots should be on the graph because (x+,y-).
Answer:
|0.254 ≤ p ≤ 0.286|
Step-by-step explanation:
Given that:
In a made up poll :
Proportion of people who like dark chocolate than milk chocolate (p) = 27%
Margin of Error = 1.6%
Hence,
p ± margin of error
27% ± 1.6%
(27 - 1.6)% ; (27 + 1.6)%
25.4% ; 28.6%
0.254 ; 0.286
Therefore ;
Lower bound = 0.254
Upper bound = 0.286
Expressing p as an absolute value Inequality ;
|0.254 ≤ p ≤ 0.286|
Given:
6 out of 2000 students quit community college due to serious health issues.
$10,000 insurance company offer
$60 per year
Based on the data, there are 6 students who will be given the $10,000 insurance per year. So they need
6 * 10,000 = $60,000 to make a break-even on their insurance offer
If a student pays $60 per year, they should have
$60,000 / $60 = 1,000 students who will pay per year to reach the break-even mark of their investment. If the number of students will exceed 1,000, the company will begin to earn.
Answer:
6.48
Step-by-step explanation:
The computation of tiles are needed to make the border is shown below:-
where,
Length is 2.02 m
And, the breadth is 1.22
Now placing these values to the above formula
So, the number of tiles needed to make the border is
= 6.48
Therefore for computing the tiles are needed to make the border we simply applied the above formula.
