Answer:

14.5

Step-by-step explanation:

$\frac{2}{7} = \frac{5}{m + 3}$

$2(m + 3) = 7 \times 5$

$2m + 6 = 35$

$2m = 35 - 6$

$2m = 29$

$m = 14.5$

Answer:

m = 14.5

Step-by-step explanation:

$\frac{2}{7}$ = $\frac{5}{m+3}$ ( cross- multiply )

2(m + 3) = 35

2m + 6 = 35 ( subtract 6 from both sides )

2m = 29 ( divide both sides by 2 )

m = 14.5

There are 200 students in the 8th grade class at Alleghany Middle School. Of these students, 8% play basketball and 14% play soc

sergeinik [125]

Answer:

The probability that a student plays either basketball or soccer is 19% or 0.19.

Step-by-step explanation:

Let A be the event that student play basketball and B be the event that student play soccer.

$P(A)=8\%$

$P(B)=14\%$

It is given that 6 students play on both teams.

$P(A\cap B)=\frac{6}{200}\times 100=3\%$

We have to find the probability that a student plays either basketball or soccer.

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

$P(A\cup B)=8\%+14\%-3\%$

$P(A\cup B)=19\%$

Therefore the probability that a student plays either basketball or soccer is 19% or 0.19.
