Answer:

B, D

Step-by-step explanation:

Since the number in parentheses has 1 + interest rate, subtract by 1 to find rate, which is 0.0325 or 3.25%.

Since the principal is multiplied by the parenthesis, $500 is the principal.

Step-by-step explanation:

Hey there!!

According to the question,

Initial velocity (u) = 1.5m/s.

Acceleration (a) = 2.4 m/s^2.

Time (t) = 3 s.

Final velocity (v) = ?

We have,

$a = \frac{v - u}{t}$

Put all values.

2.4 = (v-1.5)/3

2.4×3 = v - 1.5

$7.2 = v - 1.5$

$7.2 + 1.5 = v$

Therefore, her final velocity is 8.7.

Hope it helps....

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

$1-0.25=0.75$
