Each smaller donation was for $20 The largest donation was $15 greater than the smaller donation. First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios. 5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35 So the 2 smaller donations were $20 each, and the largest donation was for $35. The largest donation was $35 - $20 = $15 larger than one of the smaller donations.
Answer:
Step-by-step explanation:
Probability is the occurrence of any event it lies between 0 and 1
If there is 100 % chance to occur any event then probability is 1 and if there is no chance to occur any event then probability is 0
Probability is given by
As the total outcomes is always greater than favorable outcomes so probability will be always less than 1 and it can't be negative so greater than zero.
Answer:
It will take 5 years for the population to reach 1,944. Option D is correct.
Step-by-step explanation:
Initial population = I = 8
Final population = F = 1944
number of years = x
As given, the population is tripled every year that can be calculated using:
F = I*3^x
By putting values in this equation, we get
1944 = 8*3^x
1944/8 = 3^x
243 = 3^x
3^x = 243
3^x = 3^5
x = 5 bases are same so powers can be simplified.
Therefore, it will take 5 years for the population to reach 1,944. Option D is correct.
