PAINTING Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and
1 answer:
First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 
. Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.

Answer:
The critical value of F for this situation is 2.975.
Step-by-step explanation:
A test is being performed to determine if a particular drug, smartozine, affects maze learning in rats.
The groups are divided as follows:
- Three groups of 8 rats each are injected with one of three different doses of smartozine.
- The fourth group of 6 rats is injected with a saline solution as a control.
So, there were in total <em>k</em> = 4 groups with <em>n</em> = 30 rats.
The significance level of the test is, <em>α</em> = 0.05.
Compute the critical value of <em>F</em> as follows:
*Use the <em>F</em>-table.
Thus, the critical value of F for this situation is 2.975.
