The general rule for rotation of an object 90 degrees is (x, y) --------> (-y, x). You can use this rule to rotate a pre-image by taking the points of each vertex, translating them according to the rule, and drawing the image

Marianna [84]

Answer: hello your question is incomplete below is the missing part

Determine the proportion of radishes grown without fertilizers with weight less than 50grams

answer : p( x < 50 ) = 0.84

Step-by-step explanation:

Radish grown in without fertilizers ( normally distributed )

mean = 40 g

standard deviation = 10 g

Radish grown with fertilizers ( normally distributed )

Mean = 140 g

standard deviation = 40 g

<u>Determine the proportion of radishes grown without fertilizers with weight less than 50 grams </u>

lets assume x = radish without fertilizers

                    y = radish with fertilizers

hence

p( x < 50 )  = P (  (x-μ / б)  < \frac{50-40}{10}  )

                  = p ( z < 1 ) = 0.5 + p ( 0 < z < 1 )

                                   p( x < 50 ) = 0.5 + 0.3413 = 0.8413

attached below is the distribution related to this solution

Need now<br><br>find the discriminant of the following equation. 9x^2+12x+4=0
andrey2020 [161]

So to find the discriminant of a quadratic equation, the formula is b² - 4ac with a = x² coefficient, b = x coefficient, and c = constant. In this case, our equation is 12^2-4*9*4

Firstly, solve the multiplications and the exponents: 144-144

Next, subtract and we find that our discriminant is 0.

*Additional Info: Since the discriminant is zero, this means that this quadratic equation has 1 real solution.
