Not sure if my rule will be correct, but the equation i would use would be y=27x for the spacers and y=5x for the beads.
for 18 inch: 486 spacers and 90 beads
for 24 inch: 648 spacers and 120 beads
Answer:
$16.30
Step-by-step explanation:
Hope this helps! Have a great day!!
The given points are: (-2,4) and (6,b)
The slope is -3/2
The slope is the change in Y over the change in x.
So you get: -3/2 = (b - 4) / (6 - -2)
Simplify to get: -3/2 = (b - 4) / 8
Now we see the denominator on the right is 8 and on the left is 2, this is a scale of 4: (8 / 2 = 4) so the numerator on the right needs to be scaled by 4 as well.
The left side is -3, so the right side needs to equal -3 x 4 = -12
Now we know b - 4 = -12, solve for b:
b -4 = -12, add 4 to both sides:
b = -8
Now check:
(-2,4) (6,-8)
Slope = (-8 - 4) / (6 - -2) = -12 /8 = -3/2
b = -8
Answer:
0.85
Step-by-step explanation:
The interquartile range of any given data set is simply the difference between the Q3 and the Q1, i.e. Q3 - Q1.
Let's find the Q3 and the Q1 of the given data set: 30.8, 29.9, 30.0, 31.0, 30.1, 30.5, 30.7, 31.0
First, let's order the data given in increasing order from small to the largest value:
29.9, 30.0, 30.1, 30.5, 30.7, 30.8, 31.0, 31.0
Let's find the median:
Since the number of data set given is even number (8), our median would be the average of the 4th and 5th data value = (30.5+30.7) ÷ 2 = 30.6
Let's find Q3 and Q1
Q1 is the middle value from the median point to our left = (30.0+30.1) ÷ 2 = 30.05
Q3 is the middle value from the median point to our right = (30.8+31.0)÷2 = 30.9
Interquartile Range = 30.9 - 30.05 = 0.85
