Answer:
0.25*4=1 the square root is 1.
Step-by-step explanation:
4 1/4 hrs if you take the 1/4 and you 4 divide by 1 which will give you 0.25. Then you take the 0.25*4=1. you take that 1 and it becomes the square root of the whole problem.
Answer:
2/3 miles
Step-by-step explanation:
this question is basically asking you to find the slope between two points: (4,3) and (-2, -1)
how to find slope: (y1 - y2)/ (x1-x2)
so:
y1 =3, y2= -1
x1 = 4, x2 = -2
[3- (-1)]/[4-(-2)]
[3+1]/[4+2]
4/6
2/3 miles
Answer:
Lets say its a right angle : we know that it is 90 degrees
Since triangles are congruent to each triangle, each triangle has half as many degrees, namely 180. So this is true for any right triangle.
The confidence interval for confidence level of 
is
where 
is the sample mean, 
is the critical value for the given confidence level, 
is the standard deviation of the population, and 
is the sample size. The margin of error is the 
term.
a) For a confidence level of 
, we have 
. So in order to have a margin of error of at most 25 points, we have
so Raina should collect a sample of at least 269 students.
b) A confidence interval with a higher confidence level would more closely approximate and reflect the population, so it stands to reason that Luke should collect a larger sample than Raina to meet his 99% confidence spec.
c) For a confidence level of 
, we have 
. Then the margin of error would at most satisfy
so that Luke should collect a sample of at least 666 students.
Step-by-step explanation:
Let's simplify step-by-step.
(6)(6)x−60x+900
=36x+−60x+900
Combine Like Terms:
=36x+−60x+900
=(36x+−60x)+(900)
=−24x+900
Answer:
=−24x+900
