The area is 3/8 yd².
Area = length x width
Given:
length = 3/4 yard
width = 1/2 yard
Area = 3/4 yd * 1/2 yd
Area = 3*1/4*2
Area = 3/8 yd²
In multiplying fractions, multiply the numerators, then, multiply the denominators. lastly, simplify the fraction. 3/8 yd² is already in its simplest form.
W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
Answer:
D. -93/20
Step-by-step explanation:
-6/5 is -1.2 in decimal form so then you multiply -1.2 by 3.875 and get -4.65, convert that into a fraction and get -93/20.
The correct answer is B. random
Further explanation:
Let us define sampling first.
When the population is very large, a small portion of population is chosen to perform the experiments and examine the results.
There are multiple sampling techniques are used to draw samples out of the population.
<u>Random Sampling:</u>
In random sampling, the observations are chosen randomly which means that each observation has an equal chance of being selected.
In the given example, the teacher puts the names of students on papers and puts them in a bad. If she has to draw a name, each name has an equal chance of being drawn so the technique used by the teacher is simple random sampling.
The correct answer is B. random
