The answer to your question is: letter A

Step-by-step explanation:

From the graph we get the points,

P (2,1)

Q (6,8)

Formula

d = √((x2-x1)² + (y2-y1)²)

d = √((6-2)² + (8-1)²)

d = √ (4² + 7²)

An elementary school is offering 3 language classes: one in Spanish, one in French,and one in German. The classes are open to an
Alona [7]

Answer:

A. 0.5

B. 0.32

C. 0.75

Step-by-step explanation:

There are

  • 28 students in the Spanish class,
  • 26 in the French class,
  • 16 in the German class,
  • 12 students that are in both Spanish and French,
  • 4 that are in both Spanish and German,
  • 6 that are in both French and German,
  • 2 students taking all 3 classes.

So,

  • 2 students taking all 3 classes,
  • 6 - 2 = 4 students are in French and German, bu are not in Spanish,
  • 4 - 2 = 2 students are in Spanish and German, but are not in French,
  • 12 - 2 = 10 students are in Spanish and French but are not in German,
  • 16 - 2 - 4 - 2 = 8 students are only in German,
  • 26 - 2 - 4 - 10 = 10 students are only in French,
  • 28 - 2 - 2 - 10 = 14 students are only in Spanish.

In total, there are

2 + 4 + 2 + 10 + 8 + 10 +14 = 50 students.

The classes are open to any of the 100 students in the school, so

100 - 50 = 50 students are not in any of the languages classes.

A. If a student is chosen randomly, the probability that he or she is not in any of the language classes is

\dfrac{50}{100} =0.5

B. If a student is chosen randomly,  the probability that he or she is taking exactly one language class is

\dfrac{8+10+14}{100}=0.32

C. If 2 students are chosen randomly,  the probability that both are not taking any language classes is

0.5\cdot 0.5=0.25

So,  the probability that at least 1 is taking a language class is

1-0.25=0.75

What is the value of x in the equation 3/2 (4X - 1) - 3x = 5/4 - (x +2)
Leokris [45]

Step-by-step explanation:

3/2(4x-1)-3x = 5/4-(x+2)

6x -3/2 -3x = 5/4 -x -2

3x -3/2 = 5/4-2-x

4x=5/4 -2 +3/2

4x= (5-8+6)/4

4x=3/4

x=3/16

Need help with this math problem
-BARSIC- [3]

z = 37°

Step-by-step explanation:

The exterior angle theorem says that the sum of two internal angles is equal to the exterior angle

In this case the sum of z and z+4 will be equal to z+41

Writing mathematically

z + z+ 4 = z + 41\\2z+4 = z + 41\\2z -z = 41 -4\\z = 37

Hence

z = 37°

Help eight graders i don't understand this number 13
Evgen [1.6K]
<span>Just do 11-2 to get 9 so your answer is x to the 9th power where 9 is the exponent. Remember if u have to divide two numbers (same base or same number) and they have different exponents just subtract the exponents (top exponent minus bottom exponent)</span>
