Question: (a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?
Answer:
Given equation is y = 6x + 8.
Where y represents the number of baskets of berries the workers picked over a period of time x in hours.
Compare with slope intercept form y=mx+b, we get m=6 and b=8
Hence slope is 6 and y-intercept is 8.

Question: (b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
Answer:
Rate of change means slope so answer is 6.
Initial amount means y-intercept so that is 8.
rate of change of 6 means six baskets of berries are picked by workers in 1 hour.
Initial amount of 8 means there was 8 baskets of berries already filled in the beginning.

Question: (c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.
Answer:
first we graph y-intercept that is at point (0,8)
slope = 6 means make another point which is 6 unit up then 1 unit right from (0,8) so the new point is at (1,14)
Hence final graph is the line joining both points.
Answer:
2.0%
Step-by-step explanation:
The probability of two events happening in the sequence is calculated by multiplying the probability of each event happening separately by one another. Since there are a total of 7 letters in this word then the probability of choosing one letter correctly is . Since the first letter is replaced before choosing the second letter the probability remains the same. Therefore, the sequence would be the following...
= 0.020164 or 2.0%
This is an independent scenario because it does not depend on any external factors and under these circumstances the percentage will remain the same.
Answer:
<h2>270 ft²</h2>Step-by-step explanation:
<h3>METHOD 1:</h3><em>Look at the picture</em>
We can divide a given polygon into three rectangles:
The formula of an area of a rectangle <em>l × w </em>:
Calculate the area of each of the rectangles:
The area of the given polygon:
<em>Look at the second picture</em>.
We subtract the field of the smaller rectangle (<em>11ft × 6ft</em>) from the field of the large rectangle (<em>21ft × 16ft</em>):
