the area (A ) of the trim is the area of the window frame subtract the area of glass
area of window frame = (5x + 3)(x + 6) = 5x² + 33x + 18
A = 5x² + 33x + 18 - (4x² + 26x + 15)
= 5x^2 + 33x + 18 - 4x² - 26x - 15 = x² +7x + 3 inches²
Answer: 7/12
Step-by-step explanation:
1/3 + 1/3 = 2/3
2/3 - 1/3 = 1/3 (Rearrange the denominator together)
= 1/3 + 1/4
(Multiple 1/3 by 4 for the numerator and the denominator)
(Multiply 1/4 by 3 for the numerator and the denominator as well)
= 4 + 3 / 12
=7/12
The new mixture has a total volume of 5 L + 9 L = 14 L.
70% of the 5 L alcohol solution is alcohol, so that it contributed 3.5 L of alcohol to the mixture. The pure water contributed no alcohol. So in the mixture, the concentration of alcohol is
3.5 L / 14 L = 0.25, or 25%
199.
the z score for the 90th percentile is 1.28, so you can solve the equation
which gets you the 199
Answer: The value is from discrete data set.
Step-by-step explanation:
Since we have given that
Discrete data set is the data set which can be measured in numbers.
Continuous data set is the data set which can take any value within an interval.
As we have mention that
Area of a park = 9.5 acres
So, it is the exact number so, it can be measured in numbers.
so, it is discrete data set.
Hence, the value is from discrete data set.
