First one (x,y)=(0,-25/2) Second one (x,y)=(0,-26/3
Answer:
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here, we have 2.25000 and notice that there
is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would
need to move to get back to the original number, 225,000.
Since we would need to move the decimal point 5 places to the right,
we have an exponent of positive 5.
Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.
So we have .
Notice that the exponent is positive.
This is because we would need to move the decimal point to the right in order to get back to the original number.
So 2,917,000 can be written in scientific notation
as or just .
Remember that we can drop zeroes at the end of a decimal.
So we have .
Answer:
The standard deviation reduces when sample size (n) increases
Step-by-step explanation:
From the above information given, we have that mean = 75.5
Standard deviation = 3.5
But Standard deviation = √summation (x-u)/n
This simply implies that when sample (n) is increased there would be a reduction in the standard deviate.
Answer:
Infinite solutions.
Step-by-step explanation:
Just plug your equation into desmos graphing calculator and it will graph it for you. If it is infinite the two lines will lay on top of one another. If there is only one solution it will be where the two lines intersect. If there are no solutions the two lines will be parallel.
Answer:
x=0 or x=4
Step-by-step explanation:
<u>Lets Solve!</u>
First we need to factor the left side of the equation. Both terms include x.
If we multiplied x by (x-4) we would be back at .
Set factors equal to 0.
x=0 or x−4=0
x=0 or x=4
