Enter and solve a polynomial equation for the situation described.
klasskru [66]

Height = x (This is given)

Length = 5x

Width = 6x

Volume = length × width × height

The equation will be: (5x)(6x)(x) = 1920

simplify:

30x² × (x) = 1920

30x³ = 1920

Divide both sides by 30

x³= 64

x = ∛64

x= 4

If x = height, then, the height is 4cm

5x = length

20cm = length

6x = width

24cm = width

Brad has 10,000 in the bank and saves $225 each month. Write an equation to compute how much money Brad has saved. Let y be the
Yuri [45]
The equation is
y = $10,000+ $225x


<em>$225 (6) + $10,000 = y</em>

<em>$1,350 + $10,000 = y</em>

<em>$11,350 = y</em>

He will have saved $11,350 dollars in six months.

Solve this plssssssssssss
Kobotan [32]

Answer:

2 x^ (3/2)

Step-by-step explanation:

(x^2+x^2)

----------------

x^1/2

Combine like terms

2x^2

-----------

x^1/2

When dividing exponents with the same base, we subtract

a^b/ a^c = a^ (b-c)

2 * (x^2/ x^1/2) = 2( x^(2-1/2)) = 2 * x^ (3/2)

When you construct a confidence interval for the difference between two proportions, what do you use as an unbiased estimate of
Liono4ka [1.6K]

Answer:

Thus difference in sample proportions would be the unbiased estimate of the difference between the two proportions

Step-by-step explanation:

Given that you construct a confidence interval for the difference between two proportions

Let the proportions be p1 and p2

Sample sizes be n1 and n2

For samples of larger size randomly drawn we know that

p1 follows Normal with mean = sample proportion = p1 and

p2 is N with mean = sample proportion p2

Assuming these two proportions are independent we have

p1-p2 will follow a normal distribution with mean = p1-p2

Thus difference in sample proportions would be the unbiased estimate of the difference between the two proportions
