Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
We have the slope m = 3 and the point (-2, 3). Substitute:
the point-slope form
<em>use the distributive property</em>
<em>add 3 to both sides</em>
the slope-intercept form
<em>subtract 3x from both sides</em>
<em>change the signs</em>
the standard form
<em>add 9 to both sides</em>
the general form
3/4 divided by 1/6
copy dot flip
3/4 * 6/1
18/4
divide by 2 on top and bottom
9/2
4 1/2
Choice D
A = base side=3
b= base side=5
c = base side=3
h= height=7-4=3
l= lenght=6
w= width=5
h= height=4
V= 1/4h√(-a⁴+2(ab)²+2(ac)²-b⁴+2(bc)²-c⁴) + l w h
V=12.44+ 120=132.44 unit³
Answer:
3
Step-by-step explanation:
basically slope determined from a graph like this can be solved by counting. the formula you need to use is rise/run. choose one of the orange points on the line and then count how many spaces up the next dot is. once we have our number (3), you can count how many spaces over the dot is to the right (1) this leaves you with the fraction 3/1 or 3.
also if the dot is to the left it means the slope is negative. so if the dot is 3 up and 1 to the left the slope would be -3
Answer:
Step-by-step explanation:
Given that confidence level is 95% and sample mean is within 10 minutes of the population mean. i.e. margin of error = 10
Std deviation of population= 211 minutes
Margin of error = Z critical * std error
Std error = sigma/sq rt n = 
Hence we have
\frac{211}{\sqrt{n} }
The minimum sample size is 1710
