52.4/2= 26.2
26.2-3= 23.2
So the original number = 23.2

Step-by-step explanation:
The "opposite" of a number is that number with its sign changed.
__
- The opposite of zero is zero.
- A number and its opposite are located the same distance from zero on a number line.
- The opposite of a negative number is always a positive number.
Answer:
Expectation=240
standard deviation=3.098
Step-by-step explanation:
This is a binomial probability function with n=250 and probability of success is 96%
-The expected value is calculated as:
![E(X)=np\\\\=250\times 0.96\\\\=240](https://tex.z-dn.net/?f=E%28X%29%3Dnp%5C%5C%5C%5C%3D250%5Ctimes%200.96%5C%5C%5C%5C%3D240)
Hence, the expected germination is 240 seeds
b. From a above, we have the value of p=0.96 and n=250.
The standard deviation of germination is therefore calculated using the formula:
![\sigma=\sqrt{np(1-p)}, \ \ \ \\\\=\sqrt{250\times 0.96(1-0.96)}\\\\\\=3.098](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7Bnp%281-p%29%7D%2C%20%5C%20%5C%20%5C%20%5C%5C%5C%5C%3D%5Csqrt%7B250%5Ctimes%200.96%281-0.96%29%7D%5C%5C%5C%5C%5C%5C%3D3.098)
Hence, the standard deviation of germination is 3.098
Answer:
Step-by-step explanation:
1 yard = 3 feet
11 feet * (1 yard)/(3 feet) =11/3 yards = 3⅔ yards
Javon can cut three one-yard pieces. ⅔ yard is left over.
