Answer:

Obtuse triangle.

Step-by-step explanation:

The triangle has angle measurements of 142°, 32° and 6°.

As notas de dois alunos X e Y estão representadas no quadro abaixo. Por meio da variância, qual deles apresentou ser o mais regu

Reil [10]

Answer:

Aluno X

Step-by-step explanation:

A nota média para os alunos X e Y são, respectivamente:

$X_m=\frac{5+3+5+7}{4}=5 \\Y_m=\frac{4+9+4+3}{4}=5$

A variância é definida pela seguinte expressão:

$V=\frac{\sum(X_i-X_m)^2}{n-1}$

Onde n é o numero de termos, neste caso, n = 4.

As variâncias para cada aluno são:

$V_x=\frac{(5-5)^2+(3-5)^2+(5-5)^2+(7-5)^2}{4-1} \\V_x= 2.7\\V_y=\frac{(4-5)^2+(9-5)^2+(4-5)^2+(3-5)^2}{4-1} \\V_y= 7.3$

O aluno X apresentou uma variância menor do que o aluno Y em suas notas e, portanto, apresentou ser o mais regular.

Explain why partitioning a directed line segment into a

shtirl [24]

Answer:

Step-by-step explanation:

This is actually a very important question and it is very subtle. Let's just take an ordinary segment.

Suppose we have a segment that is this long

=========o=========

The segment up to the o is nine equal signs long.

The segment after the o is also nine equal signs long.

Here's the crunch. Since they are equal, the ratio is 1 to 1. The segment is divided in half.

Now take the second half of the question.

======o============

The left side of the o is 6 equal signs long.

The right side of the o is 12 equal signs long.

The ratio is 1:2. There are still 18 equal signs but now they are divided as 6/12 which is not the same thing as 9/9

Very interesting question.

docker41 [41]

Answer:

$\frac{7}{18}$ of the distance

Step-by-step explanation:

We know that a ferry traveled $\frac{1}{6}$ of the distance between two ports in $\frac{3}{7}$ hours.

In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :

The rate of the ferry is the same at any time.

The ferry will travel $\frac{1}{6}$ of the distance in $\frac{3}{7}$ hours.

If we divide each fraction by 3 ⇒

$\frac{\frac{1}{6}}{3}=\frac{1}{18}$ and $\frac{\frac{3}{7}}{3}=\frac{1}{7}$

We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :

The ferry will travel $\frac{1}{18}$ of the distance in $\frac{1}{7}$ hours.

Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒

$(\frac{1}{18}).7=\frac{7}{18}$ and $(\frac{1}{7}).7=1$

We found out that the ferry will travel $\frac{7}{18}$ of the distance in 1 hour.
