Since each term contains x, x= 0 is one answer Also as x^2 is a factor  it has duplicity 2.
Factoring:-

x^2 (x^2 - 4x + 3) = 0
x^2( x - 3)(x - 1) = 0

so x = 3 and x = 1 are also zeros


Answer:-   x = 0 (duplicity 2), x = 1 and x = 3.

What you must do in this case is to find the roots of the polynomial.
 We have then:
 x ^ 2 + 20x + 100 = 36
 Rewriting:
 x ^ 2 + 20x + 64 = 0
 The values of the roots are:
 x1 = -4
 x2 = -16
 Remember that the values of the roots are what make the polinome zero
 Answer:
 x1 = -4
 x2 = -16

A ferritin test is a popular test to measure a person’s current iron stores. in women, ferritin is normally distributed with a m
MArishka [77]
Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation

Random variable, x = 100
To test P(x < 100), calculate the z-score.
 z = (x-μ)/σ = (100 - 89)/23 = 0.4783

From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%

Answer: 68.4%

If Susie is late for school one particular day of the week, the probability she arrives on time the next day is 0.8. If she arri
Andre45 [30]

Answer:

0.273 = 27.3% probability that she was late on Thursday.

Step-by-step explanation:

On time on Monday, late on Thursday:

Possible outcomes (tuesday-wednesday-thursday).

on time(0.7 probability) - on time(0.7 probability) - late(0.3 probability)

on time(0.7 probability) - late(0.3 probability) - late(0.2 probability)

late(0.3 probability) - on time(0.8 probability) - late(0.3 probability)

late(0.3 probability) - late(0.2 probability) - late(0.2 probability).

What is the probability she was late on Thursday?

Sum of these four outcomes. So

p = 0.7*0.7*0.3 + 0.7*0.3*0.2 + 0.3*0.8*0.3+0.3*0.2*0.2 = 0.273

0.273 = 27.3% probability that she was late on Thursday.

Someone pls help me out

The cookies because if they have 100°C, after 30 seconds it loses half it‘s heat and now it only has 50°C.
After the next 30 seconds it loses again half the heat so it‘s 25°C.

You can theoretically continue this forever. It‘s exponential decay.
