Solve the quadratic equation by completing the square. x^2 - 10x + 18 = 0

serious [3.7K]

Okay so basically, you subtract 18 on both sides since the 18 doesn't work, making the equation
x² - 10x = -18
So then you add (b/2)², which is 25, to both sides, to get
x² - 10x + 25 = 7
After this, you factor.
(x-5)(x-5) = 7
Then you simplify.
(x-5)² = 7
Then you solve for x.
√(x-5)² = √7
x-5 = (+ or -)√7

~ x= 5 (+ or -)√7 ~

Hope this helps!

a cooler contains 50 bottles; 30 bottles of water, which 8 are lemon flavored and 20 bottles of tea, of which 5 are lemon flavor

xenn [34]

Answer:

The required probability is $\dfrac{13}{50}$

Step-by-step explanation:

Total number of bottles = 50

Total number of water bottles = 30

Total number of lemon flavored water bottles = 8

Total number of tea bottles = 20

Total number of lemon flavored tea bottles = 5

Probability of selecting a lemon flavored water bottle = Probability of selecting a water bottle $\times$ Probability of selecting a lemon bottle out of water bottles.

Probability of selecting a lemon flavored tea bottle = Probability of selecting a tea bottle $\times$ Probability of selecting a lemon bottle out of tea bottles.

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$
