Answer:
0/9 8/5
Step-by-step explanation:
Answer:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:
And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
Step-by-step explanation:
Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:
And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
Your answer should be 48x when you've completely simplified, but since we were not provided with answer choices to choose from, I cannot be for sure (unfortunately). :/ If 48x is one of your answer choices, than my answer is right! :)
Answer:
0.442m
Step-by-step explanation:
see attachment for the figure.
We know the formula :
sinθ = Perpendicular/Hypotenuse
From figure 1: when angle is 60°
perpendicular = 'h' and Hypotenuse=6m
by putting in the formula
sin 60°= h/6 (rearranging for h)
h=6 sin60°
h= 5.196m
From figure 2: when angle is 70°
perpendicular = 'h' and Hypotenuse=6m
by putting in the formula
sin 70°= h/6 (rearranging for h)
h=6 sin70°
h= 5.638m
therefore, h= 5.638-5.196=> 0.442m
the ladder will reach 0.442m much higher at the 70° angle
The definition of absolute value is the magnitude of a number without the sign.
Hope this helps!
