Yes, they are all equal to each other
Answer:
b. 0.0228
Step-by-step explanation:
We are given that
n=40
Mean,
Standard deviation,
g
We have to find the probability hat the mean weight for a sample of 40 summer squash exceeds 405.5 grams.






Hence, option b is correct.
Answer:
The reason Carlos chose A as the correct answer is because by the way 4,325,000,000 is set up in standard form he would have it set back to 4.325 x 10^-9 instead of 4.325 x 10^9
The polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.
<h3>Addition of Polynomials</h3>
Like terms should be combined together when adding polynomials.
Let x represent the polynomial expression that would be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n².
Therefore:
–7mn + 2m² + 3n² + x = 5m² + 2mn - 9n².
x = 5m² + 2mn - 9n² - (-7mn + 2m² + 3n²)
x = 5m² + 2mn - 9n² + 7mn - 2m² - 3n²
Combine like terms together.
x = 3m² - 11n² + 9mn
Therefore, the polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.
