Answer: D.
The y-intercept of the line means that the weight of the empty jar is about 160 grams.
Step-by-step explanation:
We know that the equation of line is given by , where m is the slope of the line and c is the initial amount .
For the given linear equation
where x is the number of marbles added, and y (dependent variable ) is the weight of the jar.
Slope of line m= 4.95 which is approximately 5 , thus, for every increase in marble, weight of jar increased by approx 5 gram.
To find the y intercept , put x=0, we get
y=160.03 which means if there is no marble then the weight of the jar = 160.03 grams or approximately 160 grams.
Thus, The y-intercept of the line means that the weight of the empty jar is about 160 grams.
First arrange the data in an order
3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21
a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7
Q2 = 2(16)/4 = 16/2 = 8th item = 12
Q3 = 3(16)/4 = 3(4) = 12th item = 17
IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5
b.) 82nd percentile = 82(16)/100 = 13th item = 17
c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%
Answer:
Improper its 81/10
Step-by-step explanation:
8 1/10~ we should multiply denominator with whole number then add numerator:
10 x 8 = 80+ 1 = 81
In improper its- 81/10
Hope this helps :D
Answer:
24
Step-by-step explanation:
7x4
Replace x and y in the equation with what they tell you x and y equal.
2(14) / 13 - 9(1/3)
Now simplify:
2 x 14 = 28
9 x 1/3 = 3
You now have:
28/13-3
Simplify again to het 28/10 this can be reduced to 14/5
