Answer:
70.8 kg
Step-by-step explanation:
This is a division problem.
637.2 kg / 9 = 70.8
Answer: 70.8 kg
Answer:
- quadratic function
- y-intercept: y = -6
- x-intercepts: x = 2 and x = 6
- y = 2, x = 4
- y ≥ 0
Step-by-step explanation:
The given graph is a <u>parabola</u> and so it a quadratic function.
The y-intercept is the point at which the curve <u>crosses the y-axis</u>.
From inspection of the graph, this is when y = -6.
The x-intercepts are the points at which the curve <u>crosses the x-axis</u>.
From inspection of the graph, the x-intercepts are x = 2 and x = 6.
The vertex is the <u>turning point</u> of the graph, so the <u>minimum point</u> of a parabola that opens <u>upwards</u>, and the <u>maximum</u> point of a parabola that opens <u>downwards</u>.
From inspection of the graph, the vertex is at (4, 2), so the greatest value of y is y = 2, and it occurs when x = 4.
The curve is <u>above the x-axis</u> between the interval x = 2 and x = 6.
Therefore, the function value is equal to zero or <u>positive</u> in this interval.
So the function value in the given interval is y ≥ 0.
A) The amount of coffee remaining is the amount of coffee held at the beginning minus the coffee ground each turns times the number of times the crank is turned.
This relationship can be written as:
c = 200 - 2t
B) Since the amount of coffee changes according to how many times the crank is turned (and not vice-versa), we can say that:
t = independent variable
c = dependent variable
How to compute outliers:
1) Data in chronological order:
0.8 ; 1.6 ; 3.9 ; 3.9 ; 4.4 ; 4.5 ; 6.1 ; 6.4 ; 6.5 ; 10.6 ; 11.2
2) Get median: There are 11 numbers, the 6th number is the median.
median: 4.5
3) Get Q1 and Q3.
Q1: 3.9 ; Q3 = 6.45
4) Find IQR. IQR = Q3 - Q1
IQR = 6.45 - 3.9
IQR = 2.55
5) Find inner fence and outer fence:
Multiply IQR by 1.5 → 2.55 x 1.5 = 3.825
Add result to Q3: 6.45 + 3.825 = 10.275 outer fence
Deduct result from Q1: 3.9 - 3.825 = 0.075 inner fence
Outlier are outside the 0.075 - 10.275 range

V>5
To solve
Distribute the numbers -2v<-10
Then divide -2 on each side
When divide by a negative number the sign and arrow changes
so the final equation is v>5
