3 0

Solve:

(3x-2)^2-4x(2x-3)>=0

(3x-2)(3x-2)-8x^2+12x>=0

9x^2-12x+4-8x^2+12x>=0

The solution: x^2+4>=0

I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!

A plant manufactures part whose lengths are normally distributed with a mean of 16.3 centimeters and a standard deviation of 2.5
EastWind [94]

The probability that the plant manufactures a part between 10.8 and 12.8 centimeters 13%

<h3>How to find the probability that the part is between 10.8 and 12.8 centimeters</h3>

The probability is solved z scores, this measures the amount of standard deviation sample X is from mean. the formula is below

z = (X - μ) / σ

<u>Definition of variables</u>

mean, μ = 16.3 centimeters

standard deviation, σ = 2.5 centimeters

X = 10.8 and 12.8 centimeters

z score, z

substituting into the formula

for X = 12.8 centimeters

=  (X - μ) / σ

= (12.8 - 16.3) / 2.5

= -1.4

the p value for z of -1.4 = 0.161513

for X = 10.8 centimeters

=  (X - μ) / σ

= (10.8 - 16.3) / 2.5

= -2.2

the p value for z of -2.2 = 0.027807

the probability is calculated as below

0.161513 - 0.027807= 0.133706

= 0.13

=13%

olga55 [171]

Answer:

It would be 8 years ago.

Step-by-step explanation:

-First, subtract $14.35 from $16.35, which gives you 2.

-Next, remember that $0.25 is a quarter, so how many quarters make $2?

-0.25x4 gives you a dollar, so 0.25x8 gives you 2 dollars.

Hope it helps!
