Answer:
i hope this helps :)
Step-by-step explanation:
2.1.) A = bh = 3.2 * 1.8 ≈ 5.76
2.2) Using the formula A = bh, solving for h, h = A over b = 44.4 over 7.4 ≈ 6
2.3) using the formula A = wl, solving for w, w = A over l = 38.25 over 9 = 4.25
2.4.) using the formula A = a^2, solving for a, a = = 4
2.5.) A = bh = 30 * 2 = 60
2.6.) using the formula A = bh, solving for h, h = A over b = 336 over 4 = 84
2.7.) using the formula A = bh, solving for b, b = A over h = 135 over 5 = 27
2.8.) A = wl = 18 * 30 = 540 250 * 2 = 500, 250 * 3 = 750 3
The length of the garden is 12 square units
It could be a linear graph with a negative slope
x axis is height above ground and y axis id air pressure
so there willbe a point at (0,14.7) on y axis representing the pressure at sea level. There will be another point at (3.6, 7.35) where air pressure is half that at ground level. The straight line will continue until it reaches the x axis ad (0, 7.2) where there is no air pressure.
Answer:
Step-by-step explanation:
Given
---- proportion of watches with defects
--- Number of watches
Solving (a): Represent at least 215 of 400 are defective
In inequalities, at least means:
So, the probability is represented as:
Solving (b): Calculate
Normal or Poisson: Normal distribution is characterized by 2 parameters and .
These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution
Start by calculating the mean
Calculate standard deviation
By continuity correction, we have:
So, we have:
Calculating , we have:
Calculate z score
So, we have:
Using the z score probability table, we have:
So, we have:
