7. if you have a fraction with the same denominator, to add them together you add the numerators and the keep the denominator the same. to subtract, you subtract the numerator and keep the denominator the same.
8. the whole number times the denominator and add the answer to the numerator. to subtract you so the same just subtract rather than add
Answer:
a. 78.6 square feet
b. $7.86
Step-by-step explanation:
a. This simply asks us to calculate the area of the 10 feet diameter pool
Formula for area of circle is ;
pi * r^2 = pi * d^2/4
so Area = 22/7 * 10^2/4 = 78.60 square feet
b. This will be the area of the blanket multiplied by the price per square foot of the blanket
Mathematically, we have that as;
78.60 * 0.1 = $7.86
Answer:
a is x>3
b is _> x/4 +12
c is x>-3
Step-by-step explanation: hope this helps
So taking (0,-2) and (-3,-6) then it is -2-(-6)/0-(-3) or 4/3
Answer: The statements that describe a normal distribution are;
a. The density curve is symmetric and bell-shaped.
b. The normal distribution is a continuous distribution.
Step-by-step explanation: The normal distribution is the most commonly used and important statistic tool. It is referred to as the "Bell Curve" because of its bell-shape and the the fact that it is symmetric density curve. A continuous distribution defines the possibilities of a continuous random variable and a prime example of a continuous distribution is the Normal distribution.
The normal distribution is not a discrete distribution because it does not have discrete variables. The normal distribution is not a flat line that extends from a minimum to a maximum but it is a continuous distribution that extends in a bell shape from one minimum value going up to a maximum value before descending back to another minimum value.
68% of a normal distribution curve falls with one standard deviation from the mean not 32%.
The two parameters that define a normal distribution is the mean and the standard deviation.
