Answer:
The sample size is
Step-by-step explanation:
The population proportion is
The margin of error is
From the question we are told the confidence level is 90% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the sample size is mathematically represented as
=>
=>
Answer:
Step-by-step explanation:
3x(5x+8y)=15x^2+24xy
4x(3x^2+5x-7)=12x^3+20x^2-28x
(3x+4y)(2x-7y)=6x^2+8xy-21xy-28y^2=6x^2-13xy-28y^2
(2-3a)(2a^2-3a+7)=4a^2-6a+14-6a^3+9a^2-21a=-6a^3+13a^2-27a+14
That would be 36 / 60 = 3/5 of an hour Answer
Answer:
<u>The answer would be 10^2 power.</u>
Answer:
The length of Fence B on the blueprint is 6 inches
Step-by-step explanation:
<u><em>The complete question is</em></u>
A blueprint shows a house with two fences. Fence A is 1 4/5 inches long on the blueprint and is to be 1 1/2 feet long. Fence b is 5 feet long. How long is Fence B on the blueprint?
step 1
Convert mixed number to an improper fraction
so
the scale drawing is
That means ----> 6 inches on the blueprint represent 5 feet in the actual
To find out the length of Fence B on the blueprint multiply the actual length of Fence B by the scale drawing
therefore
The length of Fence B on the blueprint is 6 inches
