Answer:y=50
Slope is zero
Step-by-step explanation:
50-50/25--25=0/50=0
The distance between two points:
(x₁,y₁), (x₂,y₂) - the coordinates of the points
The answer is A.
Make use of your knowledge of place value.
eighty-one hundredths = 81/100
Numerator and denominator have no common factors, so this fraction cannot be reduced.
Answer:
1.
2.
3.
Step-by-step explanation:
<u>QUESTION 1</u>
The given data set for the expenditure is
The formula for calculating the mean is given by,
We need to add all the expenditure and divide by the total number of days.
This gives us,
to the nearest hundredth.
<u>QUESTION 2</u>
The standard deviation of the data set is given by the formula;
This implies that,
This will give us,
to the nearest hundredth,
.
<u>QUESTION 3</u>
The variance is the square of the standard deviation.
To the nearest hundred gives,
Answer:
The function is positive at . The function has no zeros. The function is undefined at x= -4.
Step-by-step explanation:
The given function is
It is rational function. The numerator is constant and the degree of denominator function is 2, therefore the value of denominator is always positive for any value of x.
Therefore the function is positive for any real value of x. The function is positive at .
To find the zeros we have to equate numerator equal to 0.
Since this statement is false for all values of x, therefore the function has no zeros.
Equate denominator equal to 0.
The number -4 divides the number line into two parts and .
Since at x=-4 the value of the denominator is equal to 0 and the function is not defined.
