(1/2) * x^3 + 3.4y when X = 2 and Y = 5.
= (1/2) * (2^3) * 3.4(5)
= (1/2) * 8 * 17
= (1/2) * 136
= 136/2
= 68.
Answer:
According to the model, in 2025 the world population will be 8,493,750,000
Step-by-step explanation:
Rate at which population was growing per year = 0.09125 billion
Initial population figure in 1990 = 5.3 billion
World population prediction in 2010 ;
Predicted population figure :
Initial population + (population growth value per year * number of years)
number of years = (2025 - 1990) = 35 years
Predicted population figure in 2025 :
5.3 + (0.09125 * 35)
5.3 + 3.19375
= 8.49375 billion.
8,493,750,000 by 2025
The GCF of 12, 21, and 30 is 3.
The factors of 12 are: 1, 2, 3, 4, 6, 12
<span>The factors of 21 are: 1, </span>3, 7, 21
<span>The factors of 30 are: 1, 2, </span>3, 5, 6, 10, 15, 30
<span>Then the greatest common factor is 3.
</span>
The GCF of 11, and 44 is 11.
The factors of 11 are: 1, 11
The factors of 44 are: 1, 2, 4, 11, 44
Then the greatest common factor is 11.
Hope this helps.
Just add the two numbers and divide them by two
Mean and median both try to measure the central tendency in a data set. The mean is commonly used but sometimes the median is preferred.
