I really don't know how to explain it more.
Answer:
x=5
Step-by-step explanation:
Congruent triangles mean they have the same side lengths, so the equation here is x^2-7=4x-2. Then, solve the quadratic equation:
x^2-7=4x-2
x^2-4x-5=0
(x-5)(x+1)=0
x=5,-1
Since a side of a triangle can't be negative, the answer is 5.
Answer:
yes
yes is answer of this equation
Answer:
is closest to 4.
Step-by-step explanation:
Our approach consist in comparing the given cubic root with respect to other two cubic roots consecutive to each other and whose result is an integer. The following condition must be satisfied:
![n < \sqrt[3]{62} < n+1](https://tex.z-dn.net/?f=n%20%3C%20%5Csqrt%5B3%5D%7B62%7D%20%3C%20n%2B1)

If
, then the simultaneous inequation is observed:


Since 62 is closer to the upper bound, then
is closest to 4.
Answer:
The sample size must be greater than or equal to 756
Step-by-step explanation:
The formula to calculate the error of the proportion is the following

where p is the proportion, n the sample size, E is the error and z is the z-score for a confidence level of 95%
For a confidence level of 95% 
We know that for this case 
We require that the error be 0.03 as maximum
Therefore we solve for the variable n
