Answer:
The full Question is attached in the picture below.
PR = 5(9) +28 = 73
Step-by-step explanation:
Since the figure is a rectangle
SQ = PR
11x-26 = 5x +28
6x = 54
x = 9
Answer:
10
Step-by-step explanation:
10x0 is 0
10x1 is 10
Our equation for this table could be an equation in slope-intercept form:
y=mx+b
m=slope of the line:
b=y-intercept.
1) we have to calculate the slope of this line.
We need two points, you can choose two points of this table, for example:
the points (4,6) and (10,15)
m=(y-y₀)/(x-x₀)
m=(15-6)/(10-4)
m=9/6
m=3/2
2) we have to find "b";
We have this equation:
y=3/2 x +b
Now, we choose any point of this table; For example (8,12), now we find "b",
y=3/2 x+b
12=3/2 (8)+b
12=12+b
b=12-12
b=0
Therefore: the equation would be y=3/2 x
More easy:
if y vary directly with x, then: y=(y₂-y₁)/(x₂-x₁) x
You choose any two points of this table:
(8,12)
(10,15)
y=(15-12)/(10-8) x
y=3/2 x
Answer: y=3/2 x
Answer:
1, 3
Step-by-step explanation:
theyre across from each other.
The empirical rule says that roughly 99.7% of the population is within 3 standard deviations of the mean.
Start at the center 60 which is the mean. Add on 3 standard deviations
60 + 3*4.5 = 73.5
and subtract off 3 standard deviations from the mean
60 - 3*4.5 = 46.5
So roughly 99.7% of the population of cattle has horn lengths between 46.5 inches and 73.5 inches
<h3>Answer: Choice D. 46.5 in - 73.5 in</h3>
