100 sq. ft of the yard is covered with bricks
Step-by-step explanation:
- Step 1: Find the area of the square part of the yard.
Length of the square part = 10 ft
Area of a square = (side length)²
⇒ Area of the yard covered with bricks = 10² = 100 sq. ft
Answer:
1/2 so A
Step-by-step explanation:
The others are actual ratios you cant be able to determine what is that ratio and this means it may not even be a ratio in standards in that process.
Answer:
The sample mean is and the sample median is 0.56
Step-by-step explanation:
The sample mean of observations is given by
Applying the above definition we get that
The sum of these 15 sample observations is
and the sample mean is
The sample median is obtained by first ordering the <em>n</em> observations from smallest to largest (with any repeated values included so that every sample observation appears in the ordered list). Then,
Sample median = The single middle value if n is odd =
Sample median = The average of the two middle values if n is even = average of and
Applying the above definition we get that
The data is already ordered and n = 15 so,
Sample median = = 0.56
Answer:Is an estimate of the average grams of salt used in 2012
Step-by-step explanation: Let
x ---> the number of years since 2012
f(x) ---> is the total amount of salt ingested in grams
we have
This is a linear equation in slope intercept form
where
The slope is equal to
The y-intercept or initial value is equal to
The y-intercept is the value of the function f(x) when the value of x is equal to zero
In this context, the y-intercept is the average amount of grams of salt ingested in the year 2012
The exact value of the average amount of grams of salt ingested in the year 2012 is 3,554 grams (see the data in the table)
Compare the exact value with the y-intercept
therefore
3,548 grams Is an estimate of the average grams of salt used in 2012
