Answer:
to get the circumference 3.14×14=43.96
radious is doubled because it is half the diameter
I included an attatchment of -8y - y = 8 graphed.
x-intercept: (-1, 0)
y-intercept: (0, -8)
domian: {x | all real numbers}
range: {y | all real numbers}
Is the question what c is?
if so just subtract 3 from 10
3-10 = -7
therefore c = -7
hope that helps :)
Answer:
x=27.5
FG=72.5
GH=60
HF=47.5
Step-by-step explanation:
Sum of angles in a triangle=180
Therefore, FG+GH+HF=180
Substituting the values we have,
(3x - 10) + (2x+5) +(x+20) = 180
Collecting like terms
3x+2x+x = 180 +10 - 5 - 20
6x = 165
X= 27.5
FG = (3x - 10) = 3(27.5) - 10
FG= 72.5
GH= (2x+5) = 2(27.5)+5
GH=60
HF= x+20 =27.5+20
HF=47.5
Answer:
<em>95% confidence interval for the proportion of blocks that are sufficiently strong</em>
<em>(0.83913 , 1.02293)</em>
Step-by-step explanation:
<u><em>Step:-1</em></u>
Given that the sample size 'n' = 29 blocks
<em>Estimate proportion </em>
<u><em>Step:-2</em></u>
<em>95% confidence interval for the proportion of blocks that are sufficiently strong</em>
(0.93103 - 0.0919 , 0.93103 +0.0919)
(0.83913 , 1.02293)
<u><em>Final answer</em></u>:-
<em>95% confidence interval for the proportion of blocks that are sufficiently strong</em>
<em>(0.83913 , 1.02293)</em>
