Apopulation of hyenas inhabits a tropical savanna. at the beginning of the year, there were 100 hyenas in the population. throughout the year, 20 hyenas died, 35 hyenas were born, 5 hyenas migrated into the population, and no hyenas left the population. what was the size of the population at the end of the year?

120 hyenas will be in population at the end of year.

Explanation:

Given data:

At the start of year:

Total no. of hyenas:  100Hyenas died = 20Left hyenas = 100 - 20 = 80Hyenas who are born = 35Now the population = 80 + 35 = 115Hyenas migrated into the population = 5So the increase in population due to migrated hyenas = 115 + 5 = 120

Hence the total no. of hyenas at the end of year is 120 hyenas. Actually increase in population due to new born and migration is 35 + 5 = 40.

Due to which population become 140. But 20 of them die, making population of hyenas 120.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
