There are 870 boys and 800 girls in a school The probability that a boy chosen at random studies Spanish is 2 thirds the probability that a girl chosen at random studies Spanish is three fifths. Work out the number of students in the school who study Spanish

1060

Step-by-step explanation:

Given:

No. of boys = 870

No. of girls = 800

Probability that a boy chosen studies Spanish =

Probability that a girl chosen studies Spanish =

the number of boys in the school who study Spanish :

the number of girls in the school who study Spanish :

Therefore, total number of students who study Spanish would be :

480+580=1060

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
