Answer: The experimental probability of 2/9
Step-by-step explanation:
2/18= 1/9 * 2= 2/9 so on the first try,she sold 2 out of 18 which means the experimental probability is 2/18 = 1/9 so since this is the second try, you will have to multiply 1/9 by 2 to find the next possible outcome.
Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
276.45 divides by 5.82 = 47.5
The Harper family was traveling at a rate of 47.5 miles per hour
Answer:
4 < x < 14
Step-by-step explanation:
The third side is between the difference and the sum of the other two sides
9-5 < x < 9+5
4 < x < 14
U=π(r+h)
r+h=U/π
r=U/π - h
Data:
U=16 1/2=16 + 1/2=(16*2+1)/2=33/2
h=2
π=22/7
Then:
r=U/π - h
r=(33/2)/(22/7) - 2
r=(33*7)/(2*22) - 2
r=231 /44 - 2
r=(231-2*44)/ 44
r=(231-88)/44
r=143/44 = (3*44 + 11)/44=3 11/44
Answer: r=143/44 or 3 11/44
