The lengths of the sides of a triangle are in the ratio

Mathematics
1 answer:
Anton [14]3 years ago
5 0
HOW TO SOLVE:

1) use x as a variable
2) the starting equation is:
          4x + 3x + 5x = 18

3) add all the like terms on the left side of the equation:
          12x = 18

4) Divide by 12 on both sides:
          x=1.5

5) Find the lengths of the sides:

        - 4x = 4(1.5) = 6

        - 3x = 3(1.5) =  4.5

       - 5x = 5(1.5) = 7.5

SO, the lengths of the sides of this triangle are: 6, 4.5, and 7.5

Answer:

21.21%

Step-by-step explanation:

Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.

Sample size(n)= 402

We know that standard deviation is given as

\sigma = \sqrt {\dfrac {p(1-p)}{n}}

Now by putting the values

\sigma = \sqrt {\dfrac{0.52\times 0.48}{402}}

σ=0.0249

Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249

We know that Z=\dfrac{\bar{X}-\mu }{\sigma }

So

Z=\dfrac{0.5-0.52 }{0.0249}

Z= -0.80

So P(Z<-.80) =0.2118 from standard table.

So the probability of news paper to predict defeat is 21.21%
