Answer:
The answer to the question is -x+7.
Answer:
x = 0, x = 1
Explanation:
3x^2 - x = 2x
3x^2 -x -2x = 0
3x^2 -3x = 0
3x(x-1) = 0
x = 0, x = 1
Answer:
h = 12 cm
Step-by-step explanation:
Given that,
The area of the can of a soup, A = 354.2 cm²
Radius of the can, r = 4.7 cm
We need to find the height of the can. The formula for the volume of a cylinder is given by :
So, the height of the can is equal to 12 cm.
Using the normal distribution, it is found that approximately 79.67% of the bags weigh 3.00 ounces or more.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The proportion of the bags that weigh 3.00 ounces or more is <u>one subtracted by the p-value of Z when X = 3</u>, hence:
Z = -0.83
Z = -0.83 has a p-value of 0.2033.
1 - 0.2033 = 0.7967 = 79.67%.
79.67% of the bags weigh 3.00 ounces or more.
