Pythagorean Theorem! I slacked off very the Weekend trying to sleep cause I've been overworked <br>

Lina20 [59]

Answer:

Step-by-step explanation:

The Pythagorean Theorem says if you have a right triangle with legs $a \text{ and } b \text{ ,and hypotenuse,} c \text{,}$ then:

$a^2+b^2=c^2$ .

You are given leg measurements 12 and 16.

You are given the hypotenuse measurement but are asked to find it.

$12^2+16^2=c^2$

$144+256=c^2$

$400=c^2$

Take square root of both sides:

$20=c$

A school offers band and chorus classes. The table shows the percents of the 1200 students in the school who are enrolled in ban

julsineya [31]

Using Venn probabilities, it is found that 240 students are enrolled in both classes.

<h3>Venn probabilities:</h3>

The events are:

Event A: A student is enrolled in band.

Event B: A student is enrolled in chorus.

The supposed percentages, which also represents the probabilities involving a single student, are:

50% of the students involved in the band, hence $P(A) = 0.5$ .

40% of the students involved in the chorus, hence $P(B) = 0.4$ .

30% involved in neither, hence $1 - P(A \cup B) = 0.3 \rightarrow P(A \cup B) = 0.7$ .

The percentage involved in both is:

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

Hence:

$P(A \cap B) = 0.5 + 0.4 - 0.7 = 0.2$

Then, out of 1200 students:

$0.2(1200) = 240$

240 students are enrolled in both classes.

marissa [1.9K]

Each sweater is $35
B/c in total it was $160
And we know that the skirt is $20
So we do 160-20 which is equal to 140
There are 4 sweaters so 140 divided by 4 which is
