Answer:
C. 49 sq units
Step-by-step explanation:
Area of a triangle is
A = 1/2bh
base is 14 and height is 7
14 * 1/2 is 7
7*7 = 49
Answer:
8x - 6
Step-by-step explanation:
5x - 2 - (-3x + 4)
1) Distribute
5x - 2 + 3x -4
2) Combine like terms
8x - 6

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.
