Answer:
(5x²y⁴z/2x^5z³)
Step-by-step explanation:
That's a wacky looking multiplication! All you really need to do here is multiply straight across as you usually would; reducing terms and combining like terms where applicable.
(4x²y³z/9)•(45y/8x^5z³)=
(4•45•x²y⁴z/9•8x^5z³)= (<-- I reduce here)
(5•x²y⁴z/2x^5z³)=
(5x²y⁴z/2x^5z³)
You could put the "x" into the denominator as well and combine those terms, but I don't really see a good reason to do so.
Answer:
50.31 yards
Step-by-step explanation:
divide the length value by 914.4
46,000/914.4 = 50.31

Answer:
Width is 18 inches
Perimeter is 99 inches
Area is 567 square inches
Step-by-step explanation:
The ratio of width to length is 4 : 7
The length is 31.5 inches
The width = (31.5 ×4) ÷ 7 = 18 inches
Perimeter = 2(length + width)
Perimeter = 2(31.5 + 18) inches = 99 inches
Area =length × width
Area = 31.5 inches × 18 inches = 576 square inches.
4/7 to a percent is about 57 percent.
Answer:
a) The symbol for sample standard deviation is S
b) The symbol for population standard deviation is б (sigma)
c) The symbol for sample variance
d)The symbol for population variance is
Step-by-step explanation:
Step 1:-
Population:- Population consists of the total of the observations with which we are concerned.
Parameters:- The statistical constants of the population namely mean , variance and standard deviation 'б '
Sample:- A sample is a subset of a Population
statistics:-
he statistical constants of the sample namely mean , variance and standard deviation 'S '
step2:-
a) The symbol for sample standard deviation is S
b) The symbol for population standard deviation is б (sigma)
c) The symbol for sample variance
d)The symbol for population variance is
