Answer:
1/2 or 0.5 in decimal
Step-by-step explanation:
you would want to make the 3/10 eqale to 20/100 like it has to have the same denominatior which is 10x10 and 3x10. because 10x10 eqal to 100, and what you do to the bottom you have to do the same on the top. and then you add which becomes 30/100+20/100=50/100 and 50/100 =1/2 if you simplfiy.
Answer:
174 inches squared
Step-by-step explanation:
First, we have to remember what the area of a triangle is:

Since there are 4 of the same triangle, multiply the area of one triangle by 4:




Answer:

Step-by-step explanation:
(2nm⁻³) * 2m³n⁻³
First, focus on the coefficients, 2*2 = 4.
Now the n, n * n⁻³ = n⁻²
Now the m, m⁻³ * m³ = m⁰ = 1
Now multiply altogether, 4n⁻²(1) = 
Answer: The standard deviation of the sampling distribution is 0.0110
Step-by-step explanation:
The standard deviation of the sampling distribution is given by :-

, where p = population proportion and n = sample size.
Let
denote the proportion in the sample who say they support the increase.
As per given :

Then , the standard deviation of the sampling distribution is

Hence, the standard deviation of the sampling distribution is 0.0110.
