Answer:
C = 2·π·r. Se multiplicarmos o raio da circunferência por 2, encontraremos a medida do diâmetro (segmento de reta que intercepta dois pontos da circunferência passando pelo centro). ...
C = π·d. Como calcular a área de um círculo? ...
A = π·r²
Step-by-step explanation:
This is done by factoring. 1/8 is smaller than 1/2, so we can factor a 1/8 out of 1/2. This is what that looks like:
, because factoring after all is a form of division. When we divide a fraction by a fraction, we bring the lower fraction up and flip it to multiply, giving us this:
. This of course reduces to 4. So when we factor out 1/8, what we will have then is
, choice D from above.
Answer:
So, /(100÷2) = 117/50 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 234/100 is also equal to 2 17/50 when expressed as a mixed number.
Step-by-step explanation:
The set that is more variable is the daily temperature as they won't be clustered but rather spread out.
<h3>How to know the set that's more variable?</h3>
The mean of the temperature will be:
= (51 + 37 + 53 + 27 + 91 + 50 + 50 + 83 + 83 + 90)/10
= 615/10
= 61.5
The mean of the precipitation will be:
= (4.5 + 3.8 + 1.4 + 2.4 + 2.8 + 4.6 + 4.7 + 2.3 + 1.5)/10
= 28/10
= 2.8
