(8,9)
To find the midpoint of coordinates is adding all the X axis coordinates and dividing it by 2 (9+7 divided by 2=8)
Same goes for the Y axis (5+13 divided by 2= 9)
Well, start from 100% and work backwards.
It takes 5600 years to get to 50%
Another 5600 years to get to 25%
And a bit under another 5600 to get to 15% (another 5600 years would get it down to 12.5%)
Add the first two 550s to get 1120, and add about 5,000 and see which answer is closest.
In this case, D is closest at 15!w29
There are more exact ways of solving, but for a multiple choice this is faster and efficient nonetheless
Answer:
68% of the pizzas are delivered between 24 and 30 minutes
Step-by-step explanation:
First we calculate the Z-scores
We know the mean and the standard deviation.
The mean is:
The standard deviation is:
The Z-score formula is:
For the Z-score is:
For the Z-score is:
Then we look for the percentage of the data that is between deviations from the mean.
According to the empirical rule 68% of the data is less than 1 standard deviations of the mean. This means that 68% of the pizzas are delivered between 24 and 30 minutes
Wrong category friend! I believe this belongs in the health section of brainly. However the answer should be vaccines since they contain the same anti-gens that cause the disease but not enough to give us the disease, it allows our body to build an immunity to sed disease over-time.
Answer:
8 and 10
Step-by-step explanation:
All you need to know to begin setting this up is that to get from one even integer to the next consecutive even integer, add 2.
Start with x = an even integer (yes, because you say so!)
Next even integer = x + 2
"five times the first integer is equal to four times the second integer"
5x = 4(x + 2)
Distribute the 4.
5x = 4x + 8
Subtract 4x
x = 8
The two integers are 8 and 10
5(8) = 4(10) as desired!
