We can make an equation that would help this. X will be the discount rate.
4x=3.60
Now, we need to solve the equation to find what X is.
Let's divide each side by 4.
x=.9
So, we know that the item was sold for 90% of what it was before, meaning that it has a 10% discount.

A local grocer wants to find out whether how many mixed flower bouquets in his inventory everyday. To that end, kept records of
Alenkinab [10]
Given:
n = 27, sample size
df = n-1 = 26, degrees of freedom
xb = 11.8, sample mean
s = 2.3, sample standard deviation.

Because population statistics are not known, we should use the Student's t-distribution.
At 99% confidence interval, the t-value = 2.779 (from tables).
The confidence interval is
11.8 +/- 2.779*(2.3/√(27)) = 11.8 +/- 1.23 = (10.57, 13.03)

Answer: (10.6, 13.0) to the nearest tenth

The diameter of a cylindrical water tank is 12ft , and its height is 14ft . What is the volume of the tank?
Luda [366]
So the formula for finding the area of a cylinder is 2 \pi r^{2}+2 \pi rh . r=radius. If we put the numbers into the equation it is 2 \pi 6^{2}+2 \pi 6(14) We get 6 as the radius because half of 12 is 6. 6 squared is 36 and 6*14= 84. So our equation is now 2 \pi36+2 \pi84. 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(36)+6.283(84). Just multiply them. 226.188+527.772= 753.96 is your final answer.
