There are 200 students in the 7th grade class at Manchester Middle School. Of these students, 22% play football and 12% play baseball. Eight students play on both teams. What is the probability that a student plays either football or baseball?

Answers

Answer: There is 30% student plays either football or baseball.

Step-by-step explanation:

Since we have given that

Total number of students = 200

Percentage of students who play football = 22%

Number of students who play football n(F) is given by

$0.22* 200\n\n=44$

Percentage of students who play baseball = 12%

Number of students who play baseball n(B) is given by

$0.12* 200\n\n=24$

Number of students who play on both teams n(F∩B) = 8

According to rules, it becomes,

$n(F\cap B)=n(F)+n(B)-n(F\cap B)\n\nn(F\cap B)=44+24-8=60$

Probability that a student plays either football or baseball is given by

$(60)/(200)\n\n=0.3\n\n=30\%$

Hence, there is 30% student plays either football or baseball.

What is the difference? –4.16 – (–2.3)A.
–6.46

B.
–1.86

C.
1.86

D.
6.46

Answers

Simple...

you have -4.16-(-2.3)

but remember there's a negative in front of the (-2.3) so that gets switched into +2.3....

so now you'd have...

-4.16+2.3

=-1.86

Thus, your answer, B.

The answer to your question is B. Hope I helpedd

A child is standing across the street from his apartment . His mother is on their balcony . The angle of elevation between the child's eyes and his mothers eyes is 22 degrees . If the distance between their eyes is 32 feet , how far is the child standing from his apartment building ? Round to the nearest foot .

Answers

You've got a leg and an angle next to it (and another, straight one, too), which is enough to calculate any side and angle of the triangle with some knowledge of trigonometry (in my country, you need to be in the last months of 9th grade or later to know that)
To calculate the other angle, you simply substract our known one (22) from 90. Nothing interesting here.
To calculate the hypotenuse, which is actually what is requested, you need to use the cosine of 22, which is about 0.9272, this way: h=l1/cos(L1), that means our distance is 32/0.9272, which is about 34.5131 ft (doesn't matter if there are feet, cm, inches, meters or whatever)

Answer:

30 Ft
