Answer: Actually, you must use the Pythagorean Theorem!

a squared plus b squared equals c squared. So if you substitute in the values, a is 2 units and b is three units. 2 squared is 4 and 3 squared is 9.

4 + 9 = 13 so the answer is the square root of 13. (√13)

Based on the areas of the squares determine whether the triangle shown is a right triangle
Stella [2.4K]

Answer:

The answer is "triangle ABC is not a right triangle".

Step-by-step explanation:

For a right-angle triangle:

Its square upon on longest or triangular edges is equivalent to the total of the other two squares

Its parameters indicated throughout the question are;

Square of lateral length A = 7 \ inch^2

The square of lateral length B = 18 \ inch^2

The square of lateral length C=27\  inch^2

Thus, the longest side is C, as well as the size inch^2 of the squares of its two sides, is7 + 18 = 25 \ inch^2, lower than square C = 27\ inch^2, hence, the ABC triangle is not correct. Its longest edge is consequently C.

Artist 52 [7]

Answer:

8 and 2.529

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

Given that

Total number of questions is n =  40

The Probability of correct answer is p =  \frac{1}{5}

So, the probability of the wrong answer is q =  1 - \frac {1}{5} = \frac{4}{5}

Moreover, this is the binomial distribution

Based on the above information

The mean is

= n \times p

= 40\times \frac{1}{5}

= 8

Now the variance is

= 40\times \frac{1}{5} \times \frac{4}{5}

= \frac{32}{5}

So, the standard deviation is

= \sqrt{\frac{32}{5} }

= 2.529

hence, the mean and the standard deviation is 8 and 2.529 respectively

Use the quadratic formula to solve the equation.
Sergeeva-Olga [200]

ANSWER

x =  \frac{ 5  - \sqrt{ 5} }{4}  \: or  \:  \: x =  \frac{ 5 +  \sqrt{ 5} }{4}

EXPLANATION

The given quadratic equation is

4 {x}^{2}  - 10x + 5 = 0

We compare this to

a {x}^{2}  + bx + c = 0

to get a=4, b=-10, and c=5.

The quadratic formula is given by

x =  \frac{ - b \pm \sqrt{ {b}^{2}   - 4ac} }{2a}

We substitute these values into the formula to get:

x =  \frac{ -  - 10 \pm \sqrt{ {( - 10)}^{2}   - 4(4)(5)} }{2(4)}

This implies that

x =  \frac{ 10 \pm \sqrt{ 100  - 80} }{8}

x =  \frac{ 10 \pm \sqrt{ 20} }{8}

x =  \frac{ 10 \pm2 \sqrt{ 5} }{8}

x =  \frac{ 5 \pm \sqrt{ 5} }{4}

The solutions are:

x =  \frac{ 5  - \sqrt{ 5} }{4}  \: or  \:  \: x =  \frac{ 5 +  \sqrt{ 5} }{4}
