Ok, so at first this question seems tricky, since 5 does not go into 25.  However, you can't have a percentage of 1 person.  Since 5 goes into 25 5 times, then we will go with that.  So multiply 3 x 5 to get 15 girls.  Because you can't have a fraction of a single person.

You have to use proportion for this problem, so you do 
 
5 boys  =  3 girls
24 boys =  ? girls
24 times 3 equals 72. 72 divided by 5 equals 14.4. You have to round this answer to get 15 girls.
Hope this helped :D

Answer:

  245 cm²

Step-by-step explanation:

Filling in the given values, we have ...

  SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²

The surface area of the cone is about 245 cm².

<u>Spinner A</u>

  • Probability of red = 0.5,
  • Probability of blue = 0.5

<u>Spinner B</u>

  • Probability of red = 0.6,
  • Probability of blue = 0.4

<u>Probability of both A and B land on red: </u>

  • 0.5*0.6= 0.3

<u>Number of attempts to get outcome of 84 red on both spinners is:</u>

  • 84/0.3= 260

<u>Probability of both spinners land on blue:</u>

  • 0.5*0.4= 0.2

<u>Estimated number of both spinners land on blue:</u>

  • 260*0.2= 52
