Answer:
If we represent x (number of packages of saplings) on a number line graph, it will start on number 4 (number of packages Rita still has) then moves to the right to number 7, that is the number of packages when Rita started to plant.
Step-by-step explanation:
Answer:
The largest African elephant weighed 13.5 tons (27,000 pounds) The world record holder weighed this much and stood 13ft/4m tall at the shoulder. There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:
Answer:
The size of Isabella's pool is 220 liters.
Step-by-step explanation:
Let the size of Isabella's pool be 
liters, 
be the rate of fill, 
be the time of fill and 
be the volume of water filled in the pool.
As the rate of fill is constant,
Therefore, volume of water filled in the pool can be given as,
Volume of water left is given as 
From the table,
Volume of water left after 
minutes is 184 liters.
So, 
-------- 1
Volume of water left after 
minutes is 4 liters.
So, 
------------2
Multiply equation 1 by 6 and equation 2 by -1, we get
Now, we add the above equations, we get
Therefore, the size of Isabella's pool is 220 liters.
Answer:
Option b
Step-by-step explanation:
Given that a researcher measures IQ and weight for a group of college students.
In general, we think that the weight has nothing to do with IQ of a person and hence not correlated.
But if we go deep, we find that after a certain weight, the person becomes lazy and inactive with a chance to have reduced IQ
Weight gain causes also health problems including less activity of both brain and body and hence there is a chance for less IQ
So we find that as weight increases iq decreases and when weight decreases, IQ increases.
Thus we can say that there is a negative correlation but not necessarily near to one.
Hence option b is right
