Answer:
0.588
Step-by-step explanation:
By law of large number, the probability of the mean of 30 boards sample would be the same as 1 sample being between 94.8 in and 95.8 in within a normal distribution with mean 95 and standard deviation of 0.52. We can calculate this probability by subtracting the cumulative probability of 94.8 from the cumulative probability of 95.8 in.
P(94.8<x<95.8) = P(x < 95.8) - P(x < 94.8) = 0.938 - 0.35 = 0.588
Answer:
The answer is
<h2>r =4 ft</h2>
Step-by-step explanation:
Area of a circle is given by πr²
Where r is the radius
From the question
Area = 64 ft²
So the radius is
64 = πr²
Divide both sides by π
![{r}^{2} = \frac{64}{\pi}](https://tex.z-dn.net/?f=%20%7Br%7D%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B64%7D%7B%5Cpi%7D%20)
Find the square root of both sides
![r = \sqrt{ \frac{64}{\pi} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%7B%20%5Cfrac%7B64%7D%7B%5Cpi%7D%20%7D%20)
r = 4 ft

If there is a 506,211 pound whale on a scale and you add another whale of 424,809 pounds on the scale how much would they both weigh?
Answer:
-1.6
Step-by-step explanation:
x = 5x + 8
Minus 8 from both sides ( if it were negative you would add it )
( x - 8 ) = 5x ( 8 - 8 )
-8x = 5x
Now divide 5 from both sides
-8x/5 = 5x/5
x = - 1.6
Answer:
Step-by-step explanation:
Area of circle = πr² = 15 m²
Volume of Cylinder = πr²h
= 15 * 3
= 45 m³
Volume of Cone = (1/3)πr²h
![=\frac{1}{3}*15*3\\\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%2A15%2A3%5C%5C%5C%5C)
= 15 m³
