You distribute the 30x to the equation in parenthesis

So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x

Hope this helps!

30x(x-3)
lets substitute x for 1
30 * 1(1 - 3)
1 - 3 = 2
30 * 1 = 30
30 * 2 = 60
I hope I did it correctly.

The tree in Miguel's backyard is 7.1 m high How high is it in centimeters? Be sure to include the correct unit in your answer.
lesya [120]

The height of the 7.1 m tree in Miguel backyard in centimeters is 710 cm

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

1 m = 100 cm

Hence:

7.1 m = 7.1 m * 100 cm per 1 m = 710 cm

The height of the 7.1 m tree in Miguel backyard in centimeters is 710 cm

The manufacturer of the ColorSmart-5000 television set claims 95 percent of its sets last at least five years without needing a
patriot [66]

Answer:

Step-by-step explanation:

Hello!

Your study variable is X: "number of ColorSmart-5000 that didn't need repairs after 5 years of use, in a sample of 390"

X~Bi (n;ρ)

ρ: population proportion of ColorSmart-5000 that didn't need repairs after 5 years of use. ρ = 0.95

n= 390

x= 303

sample proportion ^ρ: x/n = 303/390 = 0.776 ≅ 0.78

Applying the Central Limit Theorem you approximate the distribution of the sample proportion to normal to obtain the statistic to use.

You are asked to estimate the population proportion of televisions that didn't require repairs with a confidence interval, the formula is:

^ρ±Z_{1-\alpha /2}* √[(^ρ(1-^ρ))/n]

Z_{1-\alpha /2} = Z_{0.995} = 2.58

0.78±2.58* √[(0.78(1-0.78))/390]

0.0541

[0.726;0.834]

With a confidence level of 99% you'd expect that the interval [0.726;0.834] contains the true value of the proportion of ColorSmart-5000 that didn't need repairs after 5 years of use.

I hope it helps!
