Answer:
2 cm
Step-by-step explanation:
Figure RSTU and Figure XWZY are the same meaning it has the same side lengths and angles. Also, if you reflect the shape the angle will be on the same side. The side lengths are not shown on Figure XWZY but they are the same.
Answer:
It invaluatesa to 1
Step-by-step explanation:
sin25 ∘cos65 ∘+cos25 ∘sin65 ∘=sin25
∘ sin(90 ∘−65 ∘)+cos25
∘cos(90 ∘−65 ∘ )
=sin25 ∘
sin25 ∘ +cos25 ∘cos25 ∘
=sin 2 25 ∘+cos 2 25 ∘=1
hope this helped you!
Answer:
By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by
.
What minimum percentage of commuters in Boston has a commute time within 2 standard deviations of the mean
By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean
Answer:$0.25
Step-by-step explanation:
$3.00 divide by 12= 0.25
Answer:
$2,800
Step-by-step explanation:
14,000 x 0.80 = 11,200
14,000 - 11,200 = 2,800
